As the title says.. What sort of economy are you getting out of your 3rd gen.

List your mods and the style of driving you do - even the year of the car...

For example: City/Country driving.. CAI + extractors etc etc..

This is to consolidate all the recent "OMG my cars a fuel hog" threads..

not to judge your excellent work bain, but the poll is kinda stupid (which you probably already know lol).
I can get any of those choices from a tank of fuel. It's totally dependant on conditions, driver, how much it's being thrashed.
So i just selected my best option, which was 600+. I have a TJ sports muffler, K&N panel filter, lowered springs. I get 800kms from mostly highway driving.
Atm i'm getting about 450-600 in half stop-start and half highway driving, in stop start i'm gunning it a fair bit hehe.

Yes and no..

If people put in there listed mods and how they drive, then you should beable to find out (as its a public poll) what that person gets per tank of fuel.

Some people might have a list of mods as long as my arm and get 600+kms out of tank all because they baby the car..

Others with no mods might only get 300kms a tank.. These people seeing others getting bigger and better value out of their tanks of fuel can then go and start a topic.. "Whats wrong with my car" or use the search button in regards to "poor performance" or something..

If anything, it slows down the amount of "whats your fuel economy thingo's"

Heck even the supercharged or hi-po na cars might be getting better fuel economy than some stock cars.

Stock TJ2 AWD Sports consistently around 520km/tank. All city driving, in Grandma mode.

Stock TL AWD, City driving, for more details.. look at my sig.

Not quite stock KL AWD, my economy is ****house. In the city(where I live) I get 15-18km/100. On the open road 10 or less. Im not really that upset though, I knew it wouldnt be great on fuel when i bought it.

stock engine wise, hilly city driving, with country weekend driving. 450 - 500kms pt

3.5 kf varada auto sports muffler and hot dog + k&n filter 550klm around town baby mode and 650klms hiway driving (melb to syd).thats with full (boot slammed down) and 2 adults and 3 kids in her.

TL ES 5 speed manual. All "city driving" so to speak. Consistently get low 12L/100km around town, low 8s on highway trips.

Student with poor paying job, so it's driven like a wimp as much as possible for the "economy", I ignore the fuel economy when I'm feeling enthusiastic (up to 18l/100 in a particular week) so I guess that is the point of the poll.

3.5 TH Sports. No engine or exhaust mods. Stereo gear is the only weight. With all city driving and a mixure of driving hard and soft I get about 10.5l/100kms which is about 550-600ltrs to the tank.
Oh and thats running Premium Unleaded all the time.

96 TE V6 Auto Sedan

Cold Air Intake and K&N Panel Filter
Done Roughly 144k kms.

Mostly Stop Start City Driving, with a bit of a burst here and there.

i get 500 -550
usually.

magna tf auto, cat back exhaust,

i can stretch it it more, if i didn't have the p plater streak ( off the traffic light bursts)

sometimes less if i use only 1st 2nd and 3rd gears,

i range from high 10's-13L/100km depending on how i drive it and the condtions in the city/suburban roads. i got about mid to low 8 or close 9L/100km (can't really remember) when did alot of highway driving @ mostly 110km/h and a tiny bit of city driving. i drive a 98 TF V6 Solara auto, all stock and my a/c is rarely on. i have never driven till the fuel light comes on, it only get close to E then its filled up and when it got there the last time, only about 50 odd litres of fuel went in and i did about 530km on that tank. I only fill up with regular unleaded.

haha im happy to get 350 out of my tank.
highway i get 600 but i do all driving round town.
with nos its about 350 aswell, depends how many bottles i use :D

i average 550-600 with my normal day-day driving, get an easy 600-650 with country driving, havent tried my car long distance yet, but dad's 3.0 TE wagon got over 700!!

99 TH exec. Mods: hotdog and aftermarket muffler, K&N panal filter. get about 550 out of a tank of optimax but the ks are slowly goin up as i drive more light footed lol. when first got the car was getting bout 350-400 and for the past year im slowly gettin more out of a tank. do 50% city run and 50% suburban driving.

99TH Altera, only perf mod is cat-back Redback system. Get around 500 or so, majority of my driving is a 3 min drive from home to work and back at night, so thats not gonna help. Mildura is full of roundabouts too...and when theyre on an 80kay road theres a fair bit of brake/accel all over town. Cannot complain about open road though. Nearly did Adelaide and back, so gettin on 850-900 in that tank i reckon...fairly big esstimate though

2003 TJ2 Sports Manual. Normally get about 450 kilometre's out of a tank. Have Extractors, new muffler and K&N panel filter. Generally use the car for travelling to and from work and some miscellanous cruising. Also the occasional bout of traffic light Grand Prix. :redface:

01 TJ 5spd auto. around 600km (11.5/100)tank combo city highway. extractors ,modified CAI, std sports muffler k&n panel

2001 TJ auto, no mods, its done 110,000ks, tyres at 35psi, well serviced and looked
after....

800+ per tank is easy. Premium fuel, but I see no difference with ordinary ULP. 99%
country driving, flat roads, semi grandpa mode, nearest town worthy of the name is 240k away. Low 8s/100k is average. Chasing economy I get into the 7s, but air con drives
it up over the 8 mark again....

A couple of weeks ago I drove the 240k to the nearest "city", and not being in a hurry I
tried to see just how good I could get the fuel economy. Sitting on 103k, no air con,
granny mode "on".....I saw 7.5 average consumption just as I got to the outskirts.

Best ever! I don't think I can get better than that. Maybe if I sat on 90kph, but that
gets very boring....getting the 7.5 figure was boring enough.....

But city driving, even just around town, is a different story. Economy goes out the window. 10 litre/100k....11.....12.

Old One.

city/suburb drivin, 03 tj vrx man, no engine mods. 400-450 from one tank.

80% city driving at 60 to 70 kms lotsa red lights i still get about 500kms to the full tank

Te manual-no mods-mostly grandpa driving (sitting at the 100km speed limit)
About 90% highway driving, but theres some big hills to go up and down.
You forgot to define how much a "tank" was Bain, if i used the whole 71L the range would be around 750-800km. But for some reason my fuel light comes on at around 51L :confused:

CAI, VR-X muffler, Other than that i got 11.5 -12.3 /100km every week but since ive added the CAI ive got 13.5/100kms so the CAI is coming off.

I usually get over 700km from a tank (bloody expensive to fill though:rant: ) with a mixture of approximately 65% freeway and 35% suburban driving (commuting to and from work with no passengers). It works out around 8.5-9.5l/100km give or take.

If I go out driving on the weekend I get a bit less obviously (more suburban driving, may have passengers = less fuel economy).

Car is mechanically stock and runs on normal ULP.

kbye:)

I get about 750 kilometres from a tank generally, and this is mainly Melbourne to Geelong. I find that running about the suburbs doesn't hurt that figure too much, providing that there is not too much stop/start. I have seen an average figure of mid 6 litres per 100kms on the trip computer while travelling in Gippsland over a distance of 100 kilometres or so. This is in a TH Advance 3.5 auto.

2000 3.5l TH Advance Wagon. Totally stock engine wise.


600-680km per tank(if i run it till dead empty) usually sits about 9.5-10.2 average fuel usage on the trip computer.

Country open road driving most of time to and from work, some country town driving on weekend. Usually put the boot into it overtaking trucks or lines of cars but other than that I use cruise control set to 100 most of the time with minimal stops and starts through towns/at intersections.

mods = Pod, Zorst, Stractors, eManage

driving style = on the quick side, all the time

401-450 a tanks :D (without the fuel light turningo on, never seen it lol)

You probably had 20L left in the car and thats why it never came on.

yeah ive been told that before hey :D

im paranoid about the fuel level lol

TL VRX manual, no rear muffler, K&N & intake around town 620ks with the air con on, 650ks with off that's using about 65lt. I dont drive it granpa like either.

On the highway with air con on and a full car I get over 800ks out of it before the fuel light comes on and that comes on at 59lt or so. I love that, so good on fuel.

This is done on e95 fuel aswell (ethonal)

2002 TJ Manual Sports with a 2.5inch Cat back exhaust and K&N Filter and I get about 10.4L per 100km around town and I don't give it much at all to save fuel. On the Highway I get about 8.5L per 100km.

I'm looking at buying a 2002 Series 2 TJ VRX, 5 speed tip tronic. What sort of fuel economy do you reakon i will get???

City, about 450-500

TE 3.0 auto sedan Ive got 700kms for 60 L with highway driving. The light tends to come on with around 20L left. Even with the gauge well under the empty mark i have never put in more than 62l (supposed to hold 71L). Its all stock exhuast ect. Short trips around town and its all gone in 350-400kms

Has anyone fitted the vaporate collars to their car and what sort of improvment did it make?

Not quite stock KL AWD, my economy is ****house. In the city(where I live) I get 15-18km/100. On the open road 10 or less. Im not really that upset though, I knew it wouldnt be great on fuel when i bought it.

Aiiii - the burden of AWD in the city :nuts: , i feel that - I too avg about 450 - 500 ks per tank around town or 600+ on the open road, if I run it dry - however it rearly gets more than 50L used before it is refilled...

2000 TH Si 123000Ks, get 670Ks from a tank, driving it slow as, around adelaide.

401-450, 98 TF Exec, mostly city driving. Grandma driving with occasional foot to the floor.

']yeah ive been told that before hey :D

im paranoid about the fuel level lol

use your trip computer then.. it tells you how much fuel you've used (provided you reset it when ya fill up)

fuel light comes on at around 55L used.. i run it til it gets to about 65-68L used, then fill up (71L tank, still got 2 or 3 Litres in reserve:P) and its usually pretty accurate.. ive said a couple of time, ill have 66.3L of unleaded and its been within 0.2 of that figure..

most ive ever gotten out of my tank was 670 (75% highway driving) but its usually 501-550kms in normal, day to day driving..

last week i booted the crap out of it to see how quick it would go.. got 440 kms out of 62L of fuel.. which i didnt think was too bad

I did a trip over easter, Canberra - Adelaide - Port Augusta and back, clocked 3440kms on 300L of juice, mostly highways.It was loaded up to the brim, running 36 psi and it used 105 litres for the 1250 km Canberra to Adelaide (via Ouyen). even with the price of fuel it only cost $140 - not cheap but cheaper than flying a family of four. FOund the trip meter to be pretty accurate, as long as you fill it consistently. And even in Balranald it was no dearer than Canberra, price ranged from $1.31 to $1.38 on Good Friday.

On a trip I get around 8.5L/100kms(best I have seen is 7.8 without the air con on - highway only and around 110kms/hr), around town it gets scary around 12L/100 - we only live 4 kms from work & supermarkets and its 80km/hr zones everywhere with lots & lots of roundabouts!Car is an 2002 S2 exec with 66000kms with tiptronic box.

My car has never seen a full fuel tank. I'm already carrying enough luxo barge weight as it is, and dont need another 30kg or so of fuel.

Mods are extractors, 18" rims, exhaust (2.5", hi flow cat, hi flow muff).

On average I get about 14.5 - 15L / 100km. ****ty yes, my car hardly gets time to warm up before I arrive at work. On other normal city driving it's around 11.5-12.5L/100km. Country driving its 8.5L-9.5L/100km.

Subtract 0.5-1L / 100 km for the addition of a pod. However this no doubt meant the car was running lean.

My car: 17c per km.
CBR250R: 4c per km.

I can't wait till I get my bike licence.

just did a trip down south and its 300kms south of perth and i only used just over a 1/4 of fuel:badgrin:

2000 tj exec
get about 550-600 with suburban and city driving, i dont drive like a grandma either. Went away over easter car did 700kms and according to trip i had 50 left. was pretty happy with that considering i had 4 people and was packed.

I get over 600k in a working week with mostly highway then some city driving :)
Only engine/performance mod i have is a rear sports muffler and i drive in tippy shifting never before 3,000rpm cause im used to manuals and atuos are gay for shifiting before 3k, gay i tell u :P.

Mods are listed in my profile. Either way it's a high powered N/A car with a tune that is probably too rich.

On the highway, averaging around 135kph I get 11.9L/100km. Around town at the moment it's more like 18L/100km.

Fuel of choice is 95 RON premium unleaded.

98 TF Magna with no mods except interior, 135K Kms, I mainly do all city driving (stop/start) and lucky to get above 80km/h and manage around 500-550kms a tank. However If I do freeway driving I've managed to do around 625kms. That was really pushing it though :bowrofl:

My manual 3.0 TF will average about 500-550km per tank (on a normal work week, so I usally drive on the same roads).

99 TH 3.5 4-speed auto Solara, mechanically stock with 154,000 kms on the clock. Tyres new about 3500k's ago, running at about 34-36 PSI. I use BP Ultimax, or whatever that 98-octane fuel is - don't get a huge performance boost out of it over standard ULP or PULP, but I feel good knowing it isn't gunging up my fuel system. :)

The fuel light comes on at around 530kms, and the trip computer usually says I have around 80 or so to empty, so I guess that means I get around 600k (11.5L/100k) to a tank, city cycle. Then, I don't give it much stick (but I like dragging Commies off the lights, and winning :)) and I baby it for the first 5-10 mins of a trip if it's been sitting for more than 2 hours.

Highway cycle I can quite easily manage 7L/100k, or around 800k per tank, sitting on 110 - my wife's manual 2002 Corolla gets about 10L/100k city and 8ish highway. She was surprised lol

Wonder if I'll get even better fuel economy now that I've just changed the air filter... :think:

KJ 2 Verada wagon with the 5 speed tippy. No mods but has the roof bars fitted, also carries a 12kg pram and a child seat all the time. 82,000 km on the clock. Driven normally, not flogging but not granma either. Commute between Queanbeyan and Canberra CBD twice a day then running around Queanbeyan with the wife's work. Usually get about 450-500km from a tank, average around 11.9L/100km. With intake snorkel removed average is about 11.0-11.5L/100km. Due for service.

just did melb to adelaide on weekend.
filled up in melb, got all the way to adelaide (shell on south road at darlington) with one tank.

total time 8:40
total km 767km
ave speed 88.4 km/h
fuel total 59.8L
Av fuel 7.8L/100km

ride is 2002 TJ exec, normal consumption is 11-12.6 L/100km city driving.

I chose 600+. We just got 370kms out of 37 litres of fuel (10L/100km:cool: ) Half a tank for our stock 97TF Wagon. This was a Ballarat-Melbourne-Ballarat trip.

im in the 501-550 bracket with the combination of daily driving 12/100 and highway drive 9.5/100 on weekends. mods are k&n panel , barry's fuel kit, zorst and always on 95 and up octane:think:

99 Exec. 3.5 Manual. only lowered... during the week drivin to work and home (about a 4 min round trip) get about 600+ks outta the tank.. and depending if i venture into town a few times.. do some laps.. etc etc... my avg fuel normally sits around 10.5... but on the weekends, drivin to the goldie and back., with limited to no drivin whist there its usually at about 8.8l/100km

99 green exec here too...

just took it from Canberra to the Gold Coast. 2 kids, full boot. Got from Canberra to Taree on 3/4 of a tank and then filled up again. Got home with 1/4 tank to spare.. so 1200km on one and a half tanks... not bad. Trippy was telling me 7.5 to the 100km.

In town (GC) I do 9.5 to the 100km, but I travel the highway alot.

I do a drive to Brisbane and back for work once a week, average 8.5L/100km (EZBoy podbox + K&N pod, extractors + zorst) Rest of the time is a mix of small amounts of 80km/h+ and lots of 60km/h. Average on the whole is usually around 10.5L/100 per tank.

i have a standard 2000 model TH si

around town, (small country town driving to an from work) im getting 400 to 450k's with a/c on all the time stopping and starting. on a trip easily 700 to 750k's going from home to the gold coast (approx 500k's away) and driving in the city for 4days.

TJ 3.5L Sedan, 501-550km under metro driving.

my fuel consumption ranges from 11.5-12.5 so its between 550-650 really dependant on what times i drive to uni.

Mostly driving northcote - clayton (peak and non peak hour). also night time driving to city and around the suburbs

car - heavily modified n/a 3.5L tj manual

before starting the mods on my car i was able to drive to sydney on 1 tank of petrol with fuel to spare.

Just did a round trip from Adelaide to Melbourne in a 04 Stock TL AWD VRX. Average for the trip was 9.7lt/100km, including some driving around melbourne, a little dissapointed thought it would be a little lower, at least in the 8's. Hopefully the exhaust when I get it fitted will improve things.

i avg about 450kms - 500 kms before the lgihts comes up, avg about a touch under 13 100% city plus bit of towing for a long long time.

now after using the "new" shell unleaded(being using shell unleaded for a long time) my driving range dropped to 420? figure went up to like 13.7? :nuts:

the tickets and ads says it was suppose to increase your fuel economy? :doubt:

I post 550km-600km in city driving mode, It goes over 750 easily for country side driving.
Thats the rsult i am posting for my 4 cyl TE.

I will be travelling from Melbourne to Wagga Wagga Soon and will be using optimax. The drive is about 440kms (Highway). How many kms do ya think 1 full tank (72L) will give me, assuming no traffic and crusing speed of 110km/hr in 5th Gear with all 4 tyres @36psi

My car is a VRX and is stock and i'll be the only 1 in the car. So minimum weight!

ill take a guess and say 100% highway driving will result in 680kms to the 70L tank untill the light comes on.

and u will use roughly 38L to get there.

410 - 450 - short trips around the suburbs but i'm going have to do long trips to take full advance for petrol on my car, but when i reset my computer on the car it said 410km til empty, so yeah.

1998 TF V6 3.0 Auto, 207,000km


Town: 65L tests gave me between 450 and 500km. (13-14.4L / 100km):
80% gentle driving, 20% heavier accelerating

Highway: 40L got me 550Km (7.2L/100km) after throttle body clean with 95% lightfoot driving and climbing tmba range end of trip. (Equivalates to about 976km to full 71L)

I'm pretty impressed with that. I rarely floor it anymore, and dont drag it, too costly with fuel these days.

96 TE 2.4L Extractors, everything else standard under the bonnet.
A trip down south last week got me 720km to a tank of ulp. All country driving 110-120km/h.
Just ticked over 185000kms.

2004 TL stock standard. 42oookm on the clock. Brisbane - Melbourne - Brisbane. 5200 km. Standard ULP
9.1 l/100k on the way down, went up to 10.7 with a thousand km around Melbourne and back to 9.6 overall by the time I got back to Bris. Took my time but boot and back seat were pretty well full to the brim.

ive always used my odometer when i fill up, and i used to get about 500km-530km but for some reason now im only gettin about 450km to a tank and i havnt done any mods since.

anyone know how i can fix it or is it dodgy petrol that theyre given out now???

Came back from Wave Rock in WA, Travel 758km with 9L remain in tank.

This would be country side driving and off road. A main reason why I have never changed to fancy rims. But I wanted to.:doubt:

I always go until the tank is almost empty (i.e. about 67-69 L used out of the 71 L tank). That's enough to know that the fuel pickup is in the right hand side of the tank (beware of fast, long right hand corners!!). I always get 600 out of a tank, and usually get 650+. I guess that's between 10 and 11 L/100km. On longer trips I have made it to Sydney and back (about 600km) with about 20 L left (I think my best was 8.3 L/100km).

Cheers,

Could be your O2 sensor playing up, or any other sensor for that matter. Engine might need a tune? When was it last serviced/tuned?

i average bout 600km out of a tank of fuel with mainly city driving and driving reasonably to hard.. however long distance trips i get bout 750 out of a tank of fuel, my mom drove the car and she gets bout 800 but on her way to sydney she got 900 km out of a tank of fuel.

it will vary on how you drive and when you fill up to. it may give you a differnt reading if you fill the tank when it has only half a tank of fuel in it. I usually look at the fuel usage one.

How many kms did you get on the trip meter before you filled up? (not how many til your tank is empty).
If i was you Erik i'd get the car checked out for any worn items in the engine bay, it appears the owner didn't really care about the car and who knows what they haven't had fixed?
Could be causing your poor fuel economy.

it read 350km before i reset itt/filled up, i will be getting the car check out when my major service is due when it hits 105000km so after then gets done, i hope my fuel ecnomy changes, i'm gona go for a mini cruiose with my car 2day and see if it makes a differance if not i'm just going have to wait til my service is due tell mitz about and see if they can fix it.

That's really poor economy mate, if i was you i'd get the mechanic to change ALL fluids, ALL filters, maybe even all the gaskets (prob done as its a major service anyway)? may cost you an extra 1-200 bucks but will have your car running like new.
There's no way it should be that bad.

its just the trip comp averaging ur driving. if u reset it and choose instant fuel and drive around town will be something like 18l/100 on the freeway and it will drop to about 7l/100. go for a drive on the freeway it will change.

Could be your O2 sensor playing up, or any other sensor for that matter. Engine might need a tune? When was it last serviced/tuned?

yeh well it hasnt bin properly serviced for ages, i want to get that done soonish, ive just serviced it myself like oil and air filters etc. wot do you reccomend getting done in my service??? p.s its gone just over 180 000 kms

Air filter, spark plugs maybe leads, fuel filter, maybe get throttle body cleaned out, if it's dirty then it can cause worse economy

2003 TJ awd 99,000km im getting around 14.5L/100 on short trips to work 16km each way not going on any reasonable high speed roads for any length of time, taking it reasonably easy, but then nailing it quite a bit too though :D i reckon it would easily get down at least 1L/100km if i put on the std rims.... the 20's weigh a ton!! and it does make a difference to acceleration and economy (thouroughy tested on previous car) any way i get low 13's on average suburban driving not city eg... preston to springvale etc....

highest consumption to date 44.5l/100km just after i filled up and floged it for about 10min... then reset the comp...lol

driving from geelong to lorne 5 days a week in my 3L, best trip was 720kms, filled up and still had 8 litres left.:D
Average about 600-700 a tank

99 3.5l TH Manual Sports. 2.5" Full Exhaust System w/ hotdog, sports muffler & 3" dump tip, full whiteline suspension.

Ive had it six mths and never gotten less than 500klms, and that was based on fangin round the streets of Melbourne. Now living in the country(80% country/20% city cycle) it sits on 8-9l/p 100klms which gives me up to about 700ish per tank, if running premium up to 800per tank.
Its over due for a major service, which will be done shortly, including engine/gearbox oils, flush and refill brake fluid, timing belt, plugs(all 6) & leads, all filters, camshaft seals, new rocker/manifold gaskets. And a new HD clutch will be fitted at the same time.
Hoping this will make it a bit smoother.

[QUOTE=Anon]My car has never seen a full fuel tank. I'm already carrying enough luxo barge weight as it is, and dont need another 30kg or so of fuel.

How can you worth out your fuel economy if you dont filled it up???

Ok for all those worried about the trip computer:

When you reset the computer, it calculates the range to empty based on your last average fuel consumption. So if your last average fuel was like 20L/100km you're range to empty will likely be 350 -400kms. If ur last average was like 10L/100km, your range to empty will be ~600kms. So there's no need to panic.

Other things to consider:

Not all magnas are the same

1. Manual V/S Auto
2. Verada V/S Magna (Weight Factor)
3. Advance, VRX V/S Executive (Weight Factor, Power Factor)

All these contribute to fuel consumption and economy. Also for those people that have a trip computer it would be best to post all your data like your average speed etc. This would give memebers an idea of how ur fuel is being consumed

For instance i get about 450kms from 66L of petrol and my average speed is about 30km'hr according to the computer. That's because i spend a lot ot time in traffic, travel distances less than 8kms, and fill up every 2 weeks.

I bet for those people getting 550+kms ur average speed would be like 60km/h or more and travelling greater distances, hence the better fuel economy.

Cheers

i average bout 600km out of a tank of fuel with mainly city driving and driving reasonably to hard.. however long distance trips i get bout 750 out of a tank of fuel, my mom drove the car and she gets bout 800 but on her way to sydney she got 900 km out of a tank of fuel.

:nuts:
:gtfo: :gtfo:

That sort of economy is near impossible. A new BMW X5 diesel gets 900km to a tank. No disrespect to you or your mother but i think you need to get your facts straight!

?? If I drive my car like a grandpa highway driving I'll get 7.8L/100. 72 litre tank, that's 920 kms. Why is it so hard to believe?

tested this out last week
full tank gets me 635klms 50% freeway 50% city/suburbs
mines the 2.4l with K&N
is that pretty crappy for a 2.4l???:confused:

my fuel economy has gone to **** recently, but you get that when you keep holding off a much needed service (200 000kms major one coming up). Spending about $1500 on it soon though, and hopefully she'll be apples again :)

FWIW, i used to get about 11 for city driving, now its about 12.5-13 :doubt:

Did a big highway trip with a 3 people in the car, air con on, did 458ks and averaged 7.2lt per 100ks

Depending on the Fuel i get around 580 to 600 ks to a tank

Hey guys, i just filled my car 2day since my service and its increased from 420 - 550 now, thats so much better than i used to get but it will change depending what driving i do i did a long drive drive on sunday to mt dandenong so that might've help, now i'm so much happer with the car now wahoo, my average is now 12l/100, pus my car hasn't been serviced for 9 monthes.

02 ralliart magna standard, except lowering, wheels and HU

suburban driving. not much cbd material. i do like the 'buffer' of distance from the lights. so a fair few squirts and the odd quick run. but rest of the time its relatively tame light throttle accel.

trip computer returns figure of ~13.5/100Km, which i worked out to be really accurate.

i use 95RON petrol only from shell, mobil, caltex etc. BP

Just got through my first tank since I got this about 10 days ago...tank lasted 7 days...

520kms doing suburban driving and I am on the freeway alot.

I read on this forum that TEs have a 72L tank, First 2 times I filled up its bin under 60L....i was down to the 'E' on friday, 58L to fil it up...so Im thinking its a 60L tank...opinions?

This car is an exec...yet it has some features that are apparently not standard...IE cruise control...

No either you trip computer is out or it's just where the previous owner filled up all the time. I find that is I fill up at 60lt used for a few weeks the fuel guage goes to E.

I fill up after 68-69lt used anyway.

man or auto? My TE fuel light goes on at just under 1/4 a tank and thats still like 15+L of fuel. Driving my 3.0L on cruise all week going to and from work this week got me 750kms with giving it heaps overtaking cars and taking off at lights etc. :cool:
Also those with trip computers, try running the car and manually working out kms and fill ups to see if your computer is accurate. Dont just rely on your trip computer to tell you how much fuel you have left or are going through. After 6 months with my magna i know quite well what my economy should be whilst driving and the comparisons at the pump on a full tank confirm that.

te and tfs dont have trip computer, its normal for lights to go on after using only 60 ltrs or so, you can still do 50+kms easy when the lights stays on, if it flickers then 100k is possible

hmmmmmmn fuel economy...

ok so say medium driving style (slight hooning with more sober driving most of the time)

minimal mods to the 4G64 manual... catback exhaust, PAF

noramlly get bout 500ks out of it... again depending on that mix of sober driving/hoonage

jus that the exhaust sounds sooooo good when u plant it lol

tw vrx with 14,000kms on clock - on a full tank have averaged around 400-450...

Since I've had the Haltech installed and my car's been tuned to run 98 ron fuels, my economy has been nothing short of excellent. I've just run the first tank of Optimax through it and my combined cycle is reading 9.9 on the trip computer and I've done just on 670kms and have about 6 or 7 litres left in the tank. When I fill up tomorrow I'll get an accurate reading of average fuel used. But I'm very happy.

Damn that's pretty good mate, i can get under 10 if i do more than 50% highway driving, but at the moment 50/50 is giving me about 10.5L/100km.

So I guess you drive it very hard all the time? Thats like driving a v8.

I've had mine for 14months now (24000kms) and am getting 480km for 64ltrs using BP
(450km using caltex). That's 30%city/60%suburban/10% highway with two people on
board for 90% and 10% with two plus toddler for the city section, 45% by myself, 45%
with two people and 10% with two people plus a todler for the suburban section, and 50%
by myselft and 50% with two people plus a todler for the highway section. I also tend to
gun it at the lights if I'm by myself.

I did manage to get 515km for 64 litres one time when I did not gun the car at all for the
same above scenario.

Well I just filled up. Trip computer was bang on! Said I used 68 litres, and sure enough, 68 litres filled it to the brim! It also said fuel consumption was 10.0 and sure enough, exactly 10.0 combined cycle. That's probably 20% city, 5% highway and 75% suburban. If I didn't gun it to the servo flat out, I woulda averaged 9.9L/100 combined cycle. I did 685kms on 68.5l of fuel. I am happy as Larry.

Yeah mines still doing very well, my average doesnt go above 8.6 have it since Jan and now have done 35000klms. Now I do about 60% HWY and 40% Town driving most of the time with the Mrs and 2 kids.
Its overdue to be serviced so It can be better.

Luke

So I guess you drive it very hard all the time? Thats like driving a v8.

yeah - im a bit of a lead-foot :badgrin: - but i do a lot of short trips and city driving in it, so that cant help either... :confused:

I consistently get about 550km from a tank (100% city driving)
This is with cruise control being used 90% of the time
If i don't use cruise control i usually get around 520km from a tank
I love cruise!

Got a TJ 11 wagon
From Mt Gambier to Melb i averaged 8.0/100 which is about 35mpg with the family on board and heaps of luggage.
I'm happy with that

Get about 550-570Km a tank out of mine, even mixture of city and freeway driving.

im looking at all these figures and they are pretty consitent. my thought is, a late model V8 consumes only a marginally higher amount than us.

any thoughts?

Yeah, if you drive a V8 harder, you'll use more.. but with fuel prices as they are, not many ppl can afford to thrash V8's... the V8's dont have to work as hard so they use less fuel.. so to speak.
V8's can even be cheaper on the highway

im looking at all these figures and they are pretty consitent. my thought is, a late model V8 consumes only a marginally higher amount than us.

any thoughts?
V8s on the highway (the newer 6 speed manuals) use 9l/100. Take it anywhere but the highway (city, suburban) and it'll use 15-20l/100. Plant your foot and it'll use 30-50l/100.

im not talking about just highway consumption. motor and wheels always return figures of 13-14 L/100k and i think it gets upwards of 20's.

just a thought thats all.

i think its just ~4 years of automotive development and progress.

Those figures are very optimistic. I can tell you first hand as my dad owns a 2002 Monaro with an LS1 6 speed manual, and it'll return real figures of about 15-17l/100 for a combined cycle. My car returns 9.5-10.5l/100 combined cycle. There's a big diff.

Just took the car for a trip down to margaret river in WA, combination of looooong highway stretches, some heavy footed overtaking, and a few days of stop/start and winding roads. managed 680 from a full tank over 4 days. Pretty Stoked:)

Got a 5.7lt commodore 6 spd man and the mrs gota TJ series 11 auto.
Driving on the Highway only, theirs about 1lt/100 difference 8 vs 9/100 and around town 11.8 vs 12.7 not much in it.

I'm stunned at my TF's economy getting better still.. have been driving it a lot lately, seem to get 10L/100km city driving with heaps of open throttle driving and high revving.. and on the highway, 7.1L/100km is the best I've done, 495km to exactly half a tank of 35.5L and that was even with full throttle overtaking etc. Average between 7.1 and 8L/100km on highway. This car is a freak. About to take it for a 500km trip today and drive sedately to see if I can nudge it under 7L/100k.

Noob member here hiya all,
Bought myself a 02 sports about three weeks ago (sable) and so far very impressed, its lookin like at least 600+ out of a tank for me :D mainly hwy/mwy to work and back.

i got just under 10L/100km in my last tank (660km to about 65ish Litres, about 100+km of it was a flogging), i have been running my car on Shell Optimax/V-Power and wow...i have been doing rough calculation in my head when i was using regular unleaded (Shell) and i thought i was getting something between 11-12ishL/100km, so for some reason my car responds better to the premium fuel...i dunno, but i don't drive my grandma either.

That's interesting, because your motor doesn't have a knock sensor, so using different ron fuels shouldn't make a difference to the fuel economy.

hmmm true, my only explanation is maybe his timing is off/out of tune? Or the engine just isn't running at it's optimum on regular.

im in around the 470 mark full tank syd to adelaide was ok on hi way 610 per tank but around town it is crap no mods

But i have just relaised i have clogged\shagged injector so they are getting looked at in the morning
:D

and my last tank i just filled up again i got 9.3L/100km of which it consisted of some city driving, start stop, a drive on Beach road and a drive to philip island. with the mention of my engine is out of tune, i think u are right, at idle and with a broken driver's side engine mount, the engine has a rough idle, in a sense it more of a "pulsating" kind of idle...and with the car running on regular, it just doesn't sound as nice as when it runs on premium (at idle) if u wanna know what i mean i might take u out for a drive one day. i'll stick to premium now...its not too expensive atm anyway

i can get about high 500-low 600 in suburban driving, depending on how far the foot goes at times. i did get a mid 600's on one tank and that had about 40mins or something on the Monash Fwy but the needle got down the E and the fuel light was coming on and off

I'm driving a 3.5 tj magna si. Have no mods and I usually get around 550km to a tank

Reading car sales today and the official results are for a TJ 3.5:
9.0 highway, 14 city. wtf? My city driving hasn't gone over 11 and highway i can get better than 9.

Average =12
Full Tank 2day = 580km
Thats the best ever wahoo finally get a really good reading plus reset my battery 2 times this week because of my interiour light and installing steering wheel.

You sure thats not for the TJ AWD?

I notice that even with BP, I get better kays with certain petrol stations compared to
others. With the driving I do as mentioned in my previous thread, filling up at BP on corner
of South and Henley Beach Roads in Adelaide, I'm getting close to 8km/ltr or close to
12.5 l/100km. Whereas, at the BP on Churchill Rd, I'm only getting 7.5km/lt or 13.3l/100km.
These were averages taken over a period of 15 weeks, with 5 weeks on the better BP and
10 weeks on the worse BP with around 400km per week.

Hi guys,

New member here.

I have a well maintained Dec. 98 TF Sports

Done 150k on it and have been diligently checking the mileage the last 4 years by recording it in a spreadsheet.

On average (no pun intended) the average has been 8.93 kmpl or 11.19 litres per 100 kms. This is a mixture of freeway and city driving and mostly with Woolies unleaded. Have noticed that the average improves slightly with Shell unleaded. Have not noticed any discernable difference with PULP.

I'm with you on woollies petrol. Eventhough it is 4c/l cheaper with a docket, I'm actually
better of going to BP. For 400km, with petrol at $1.10 at BP and $1.06 at Woollies Caltex,
I'm saving 2 dollars per week, thats $04 a year. Better still, I've found a BP station which
has better fuel again, giving me another $2 per week.
Thus, using Woollies Caltex, I'm getting 7km/l, with the lesser BP, I'm getting 7.5km/l and
with the better BP, I'm getting close to 8km/l.

Hey guys hows things?.. Fuel Economy on my magna is freakin brilliant, I would get between 700-800 klms from a tank absolutly no worries at all (Highway driving), being in the country roads the average speed of that would be 110-115. I have done Brissy to Emerald on one tank of fuel the distance being 974km, admittingly I didnt once step over 100k/h and the average got down to 8.1ltrs/100km

I will admit the A/C does add at least 1.0ltr/100km

The Car is a TH (99) 3.5ltr Sports 5sp, I have the K 'n' N Filter as well as an extra air pipe fitted to bottom of air box. Pacemaker tuned length extractors.
The fuel tank has never seen a drop of normal unleaded fuel, from day one its been Shell Optimax or BP Ultimate. This fuel eco kills any of the "top market cars" although the Camry isnt too far behind it (Drove it for a hire car).

I reset the trip comp every trip and Im disappointed if i get more then 9.0ltr/100km, if trip says 70ltrs used generally thats about 2-3ltrs out at fuel station, this has only been like this since the introduction of the extractors.

Take it easy guys :D.... Damo

Is amazing that you really got so good fuel economy for your Magna.

Most of the time I find that the less mods you have the more Fuel economy you get.

When I was with stock wheels I get about another 50kms more than usual. But however the Verada wheels do give me a better steering and grip on the roads. is a plus minus thingy.

Well, the 16" verada alloys, been lighter than the stock 15" steels should yield better
economy. Less unsprung weight, less energy used to spin the wheels etc. However, there
is a difference between the overall diameter of the wheels:
stock: 205/65R15 = 647.5mm overall diameter
verada: 215/60R16 = 664.4mm overall diameter

So, the verada alloys are 2.61% bigger than you stockies and unless you had you speedo
and odo re-calliberated, you'll be doing 102.61km/hr when the speedo indicates 100km/hr
and for every 100km, your tacho would have only registered 97.39km, thus say if you were
getting 600km per tank before, you'd be getting (indicated) 584.3km. Thats a difference of
15.7 kms. Plus, you are probably driving it alot harder due to better grip, so add a few more
kays and there you have it.

Just out of curiosity, what RPM are the engines doing at steady 90 and 110?

With cruise control my TF 3.0 V6 churns over at ~2025 rpm whilst doing 90 kmph and ~2200 whilst doing 100 kmph

Would lesser RPM's equate to better economy?

Someone’s avatar on here had their ride happily ticking over just over ~2k @ 110. I assume that it was a 3.5 V6.

Also realised that it would vary dependant if the tranny is 4 speed, 5 speed, auto or manual......

Im the same as Disciple, 5sp man would all be round that figure although the auto's are sitting at about 2000 @ 110k/h, I noticed this when I drove a 380 auto out of adelaide. But it still only managed 9.1l/100...

I drive a TH 1999 Executive magna, only mods are 17” rims, sub, amp and spoiler, when I travel to Moonta that’s about 200km away from where I live, I can get up there and back on a half a tank of petrol doing 100km. only going that fast because im only on my P’s.

I can sometime get above 600kms but its usually just short of that. All my driving is done on highways so no stopping/starting to ruin my fuel consumption.

Dammit, How are some of you guys getting 500km to a tank? Even driving granny style I still can only manage about 400km. I once drove the tank into the ground till it was suckin fumes and it still only got about 420-430!!!

Erm... might wanna look at changing your O2 sensor or something man. I can get 600-700kms out of my tank comfortably doing suburban driving mostly. I'm averaging 9-11l/100.

Gee this is an old thread

Looks like i'll have to change my vote now from (351 - 400) to (300 - 350)

or if someone can add (Below 300) lol

You cant be serious ??.... I pretty p!$$ed if I dont get 350 out of half a tank... I noticed you have the S/C verada, has the fuel difference been since the addition of the S/C??

yes, my right foot became alot heavier as soon as I drove out of the performance shop lol

seriously i can get around 450km out of a tank but its been very hard to get close to that with the extra power under the bonnet and the awesome sound it makes.:cool:

Ahh cool, love ur honesty lol... Im in the process of S/C mine, I was like sht a brick if the fuel is like that, I'll leave the S/C in the shop.

The best I have seen out of my Parents TF v6 was driving between canberra and melbourne, with luggage and 3 of us in the car it did 7.8L per 100km. We checked and double checked the mileage, even added it up on the map. The only thing we can put it down to was steady driving at 100km and maybe a tail wind?

Remarkably it seems to be using less fuel now than it was when it was newer, possibly because mum drives 60km each way each day highway driving its obviously done the engine some good. They have never done anything to the car at all, and they keep their cars very well maintained, it has now racked up 240,000. They usually get around the high 8's driving on the highway now.

They also got 70,000km out of a set of tyres, twice. Thats also attributed to the highway driving, and the fact the Dunlop 300E's seem to be a pretty good tyre... Thats 70,000km with it still being legal tread, there's no way that dad would allows the tread to get too low!

The best I have seen out of my Parents TF v6 was driving between canberra and melbourne, with luggage and 3 of us in the car it did 7.8L per 100km. We checked and double checked the mileage, even added it up on the map. The only thing we can put it down to was steady driving at 100km and maybe a tail wind?

Is the car an automatic?.... My old man drives an auto TF, I drove it from Adelaide to Moonta (about 200k) and it averaged 7.2l/100k, I drive a 5sp TH and I would only dream of getting that economy, I get great ecomony as it is, but the only thing I put it down to was the difference with transmission. For example 110k for me is sitting at 2600-2700 revs, the auto was sitting at 2000...

As for the tyres, if I get over 50000 Im very happy, the last set lasted 3 1/2 years @ 57000klms, but that was mainly due to the fact of a company car.

Yes it is an auto, how come the manual revs so high? What on earth did they do to the later manuals! I have a TP manual myself and it revs around 2000rpm at 110 (5th gear of course).

7.2L/100km is pretty good though!

Erm... might wanna look at changing your O2 sensor or something man. I can get 600-700kms out of my tank comfortably doing suburban driving mostly. I'm averaging 9-11l/100.

Okey Dokey
So what are some basic things I can do to improve economy? Its getting a fluid flush and a cat back exhaust soon anything on top of that? Just dissapointed cause my old 2.6 TR Auto got the same 400km per tank and I thought getting a Manual 3.0ltr would improve upon that.

Number of things to check for economy, fuel filter (full of crap maybe), injectors (clogged?), air intake, yeh o2 sensor, air filter (change to k 'n' n panel)... vaccum lines (no kinks)..Check the Cat to see if its not clogged with crap.. Getting like extractors/exhaust will improve but dead set if the 3.0 / 3.5 lrt are driven within reason I cant see why you cant get 10L/100... Think anything to make the engine run easier / smoother / free will save you fuel.

Got absolutly no idea with the revs, but im sure every third gen 5sp will rev approx same... autos would be geared different (ratio), hence why they are gutless with pick-up... 7.2 is freakin excellent, like I said before i can only dream of them figures

Best fuel economy was when I did a weekend trip to Guyra... 7.6L/100. Very happy. Did it in my TJ 3.5 Wagon - stock.

Get about 550-600 with highway city combined driving. The engine is completey stock and I don't push it or anything.

Weekend trip to Yeppoon, one way trip of 310klms, drove down thursday night with an average of 9.7/100 (trip computer), 9.5L/100 actual (from pump)... Coming home last night I thought stuff it, I'll see how good I can get this fuel eco. Reset trip at Yeppoon, cruised on 110k/h (100 zone) 115k/h (110 zone), only time i went above these speeds was overtaking.

For the people who dont know the road, its pretty flat with only a few hill climbs.

Average speed for the trip 108klm, with average fuel 8.7L/100 (trip computer) and pretty much the same from the pump. I would say 400klms for half a tank. Im pretty pleased with that :D

Running a TJ Sportswagon without mods & get about 350-400kms (if lucky) per tank locally, running at 16l/100km, but get it on the freeway & then it gets up over 650km.

Vortex muffler :D some 2.5 inch piping. I'm actually surprised more people don't have one! They made here but more popular overseas!

I don't know how you guys get such bad economy figures. I've got the heaviest car here
and around town and suburbs I get 500km/tank (64ltr tank). My car has a kerb mass of
1680kg plus tow bar = 1700kg.

i sometimes struggle to get 300km :P but thats cos my car spends alot of time just sitting idling and driving around at 20km/h

Whats everyones average speed. Mine states 37.0 kph

I get 10.6L/100 on my vanilla '05 Verada AWD (avg speed of around 66km/h). My route to work is usually on 100km/h country roads and highways. No inner city stuff.

OT - Whats up with Verada AWD badges Vlad? I have 'Verada' on back left and 'GTVI' on back right with only 'AWD' on rear passenger doors. I haven't seen any other Verada like that. They all seem to have the 'AWD' badge on the back.:confused:

That would have to be a whole lot of idling! Don't they use around 2.8L per hour idling? Hmmm 20km/hr efficiency depends on what gear your in and brake use etc... lol

Driving at low speeds and extremely high speeds are both bad for fuel economy. I've
posted a webpage in the what to mod to improve fuel economy thread which contains a
graph which clearly state that fact. I've attached the graph so people don't have to
search for it.

Travelling at 15mph==24kph is worse than travelling at 75mph==120kph.

I knew there was the case, just didn't realise it was that much! Interesting to see the peaks around 35 and 55 with a dip in the middle... Weren't the basic speed limits in the US 35 and 55? Would that signify ECU tuning with only a couple of 'stations'. I have heard its the same here, that EFI cars (Australian at least) have ECU stations at like 55-65, 75-85, 105-115, etc. but wasn't sure whether it was true or not!

i basically use my car as a courier van lol my average speed is usually below 20km/h despite the fact the engine is actually running for 6-7 hours a day. Rarely gets into 4th gear, tend to brake pretty hard, lots of inner city traffic driving when i actually am moving, lots of accelerate, brake, accelerate, brake type driving.. Give you an idea as to why my economy is so crappo?

Ah ok! Well that much idling that makes sense then! If its using 10L/100km, then an average speed of 20km/hr would make it 14L (of actual fuel used when driving), plus the 2.8L/hr idling figure I suggested. That would make your daily fuel use around 28L-30L? I guess that would equate to around 300km a tank :)

The last time I filled up I'm pretty sure the 'range' gauge showed 450. Would this be a default value as per the factory or does this vary depending on the kms you clock up?

It will also go off the Last average fuel used, I have had time of where I have started on 500klms, I'll drive 100k n the reading will have gone to 550klms... :nuts:

Driving in to fill up as normal last yesterday & before I filled up yesterday checked the trip computer to find Av. Fuel = 9.4/100km where I would have expected around 11.5L. Try explain that?

Don't worry, just another one of me mindless post. When I bought the car it was running 12.7 and it's been getting better ever since.

My TF is runnin' heaps rough, Somebody said its probley my valve lifters sticking, My clutch aint slippin but feels ****, my boss said the bearings on my water pump are making a noise and my tyres are pretty much bald. Despite all this I pull the best figure so far on fuel economy with a 467km at the dead bottom. Yew! Now just have to fix up the car and figure how you guys manage 500

Despite all this I pull the best figure so far on fuel economy with a 467km at the dead bottom.

Geez, 467 is veeery thirsty ... your car must be running rough!! Mebbe check your injectors as well ... ?

I can consistently get 560-580 to a tank in my auto 3.5L TH ...!

And yeah, the trip computer does use your driving history to determine the range to empty - mine usually says 570 upon fill-up but if I'm refuelling after a long trip it goes way up to 800 or so, then drops really quickly when I get back into suburbia!

might be doin better this week, was up to 120k just (JUST JUST JUST) after the first 1/8th mark. Im goin to try a bit more restraint and avoid the need to show up Red platers and I'll check back at the end of the week with what I got out of this tank.

As soon as you plant your foot the good fuel economy is out the window. If you drive with even a slightly heavy right foot, don't expect good economy.

My Stock Solara when I picked it up said 500km to the tank, now it reads 660 - 680 and I will drive till Ive done 600+km per tank. I do city and freeway driving.

YEA!!!! THE TF DID IT!!! YEW!!!! From top of the tank to the very bottom I pulled a 573km. Hella YEAH! I dunno whats changed, in the last week the car was driving heaps rough, felt like it was gunna sh*t itself but last two days its calmed down, feels bit smoother now and this week pulled the best figure ive ever got from it """573""". I reckon I coulda hit 600km but when I saw I had 1/8 of a tank left and was at 500 I thrashed it to wollongong and back to my place then drove around a bit till the needle rested directly on the white line. YEW!!

Ralliart Auto, I get about 520kms per tank city/country driving, hard!

Freakin Confused, Thought Id be fuel wise and see what I could get going to Yeppoon (320k approx/640 round trip) on the weekend, trip down avg'd 8.6, average speed of 106k... anyways on the way home I couldnt of given a flyin rats a**e bout the ecomony and averaged 8.9, wont mention average speed thou... Is it telling me to get stuck into her and still grab 800plus out of the tank ??...Got me stuffed lol....

Only if you maintain that average for the whole tank.

That was the average over 320km, but the thing I cant work out is that the fuel usually gets sucked out when the speedo needle goes over the 1?? mark, but it was remarkably brilliant :confused:

How much over 100? The thing you have to remember is that doing higher speeds mean
that you do that speed for a shorter amount of time. I the engine is not struggling to
maintain that speed than it shouldn't be using a lot of fuel.

Covered the trip in 2hrs 35mins, averaging round the 125k mark... obviously there were times of slower n higher speeds... I was just surprised when I seen the fuel used....

Did Canberra to Sydney yesterday morning sitting on ~110, car empty except for me and got 7.8km/l, average over return trip was 8.4 on about the same speed, carrying an extra 80kgs on way back. Travelled at a constant speed.

Hi Jar
Is it possible that you have filled up with an ethanol blend ? - well known to absorb water and causing rough running before settling into a good tune - Shell is a common one

In any event can you tell us what brand/grade of fuel you have been using ?

Thanks, Barry

you've got to take into account the fact that the trip back is uphill... I've gotten into the 7's to Sydney, but never better than 8's on the way home.

it'll be interesting when I go to Sydney next month for the SC... the trip back might not be economical at all:D

of course it did. because with the pod ya just floor it all the time to hear it roar. thats not an issue with the panel

i gave the old girl a good cracking over the hols with a 550 k trip home on LPG i get about 65 ltrs of usable fuel in the tank and im just about to crack 600 or so k's but with an average speed of 107 kph for 5 hours it was nice on the juice

havnt tried out the petrol yet as i have no fuel guage for that need to macgyver 1 up switching from lpg to petrol borks the trip computer

looks like i will struggle to make 400K's around town on the same tank

i dont no what theve done but after using shells vpower i got from cairns to ayr which is 443ks on half a tank now that is pretty good

So you're saying that changing to a panel air filter instead of a pod increased your fuel economy by 100-150kms per tank? ARGFDLKJNKLJSNK><MNKJKMNJBJKFLK :nuts:
yeah mate.. but i had one of those Pods that wasnt designed for MAF, it was Cicrular one not in an oval shape, and the car was running very rich had problems sometimes with it, feeling like it was gonna stall wen i took corners etc.....

I thought ethanol blends now have to be labelled, and Shell's standard fuels aren't labelled as ethanol blend...

If they are ethanol blends they're just ripping you off, the ethanol component is far cheaper than the fuel component, so it should be several cents cheaper...

I've never had a problem with ethanol blends. Oh, I also read an article that its a simple engine management modification that is required to run E85 on most latel model cars (all the Australian built ones), which, if E85 were available here would be a very good consideration since it should be significantly cheaper (the modification costs around $200).

Filled up last week with Shell Premium, got 620k when i filled her up again and still had just over 11L left in the tank. Would of got more but i had to make a lot of short trips.

This is nuts what you guys are saying... 600 k's to a tank...? im lucky to get about 350-400 and my TF is a stock 3 litre manual. i mean yeah sometimes ill fang it round a bit but not hugely...? (never over 4000rpm). WTF is wrong with my car?????

WoW, I only get about 250- 300km's out of 50ltr's of LPG. Thats mostly around town though.

I have got close to 800km's from it on Petrol doing highway driving, sitting at 100kmh on cruise. Around town that pretty much halved, so I would expect 500 - 600km's on a trip.

Are the tank sizes any different between models and the 3.0/3.5? Mines a 71L tank.

Check your O2 sensor.

The 3rd sedans should all be 71 litres. The wagons are a tad less at 68 and the AWDs are
a tad less again at 64 litres (like the 2nd gens).

According to the owners manual in my TL VRX AWD, its stated that the fuel tank on AWD's is 70lt????. I was sure it was 65 in AWD's but on a recent trip to Melbourne the trip was showing used 68lt when I checked it whilst filling up???

yep around town lpg sucks when petty was less than $1 and lpg was about 45 - 50 c i used petrol but now there is still a bit of saving from lpg around town but if you had to go fit a lpg tank now i dont think you would recover the savings unless you do a lot of ks

just got back from a long trip.. on the way using caltex vortex i got 735k on one tank and the reserve light was just starting to come on.... avg fuel was about 9.1, sitting on 118kph on cruise (in a 110 zone too) . Wasnt going to risk tryin to get to the next town on reserve. Not so good on the way home.. further west i went, the worse the fuel got. but thats the best effort so far..

According to Carsales research section, the TL AWD has a 70l tank all other AWD variants
of L and W series has a 65l tank. However, from memory, due to the tailshaft and rear
drive shaft, the tank was split into two and thus the capacity was reduced. Mine is
definitely around the 64/65 litre mark as calculated every time I fill up.

around town about 18L/100km
Possibly 11 to 12 on the hwy.

With that amount of fuel, you might as well get a v8 falcon or commodore or a nisan patrol.

Ok, just checked my manual and it also says the AWDs have a 70L tank. Must be a
missprint as according to my last calculation of 12.59L/100 and a range to empty of 530km
after a refill, it should be 66.7L tank. Although the trip computer says 13.1L/100 avg and
with the 530km range, the tank should be 69.5L. Hmmmm, need to confirm it with Mitsu.

my trip is definately a bit out, it usually says 13-15, but everytime i fill up i only use about 12 from my calculation, ltrs filled/kms travelled :doubt:

I suppose if you drive like a granny, short shifting, it should be okay.

Doubt you will be able to resist the urge to use the extra grunt, the sound is enough to be addicted.

For the performance, particularly considering the AWD, the fuel consumption in much better than a V8.

My XB Ford 351 4V used about 30 - 35Litres per 100km when driven with only a bit of vigor, had no traction and was cop bait.

I'm sure the first month or so will be expensive on fuel, but after that I'll probably only give it one or two squirts (when necessary :badgrin: )

I always change before 3000, so I guess that would be short shifting. I don't usually run it out to red line on the way to and from work!!!

I have just done the Adelaide-Sydney trip (and return) and averaged 8.2L/100km, for the whole trip!
I'm stoked lol

This was on cruise control at 110km/hr and aircon flat out the whole time!

just got back from picking up my newly supercharged car in Sydney...

8.1L/100km on the way to Sydney (went up to 8.4 through some heavy traffic on the way to Mona Vale)

9.8L/100km on the way back (uphill!!) and through very heavy traffic (i.e. stopped on the M5, 20kmh through the last tunnel). it should be said that I didn't reset it before I started back, so that includes all the running and testing that the guys did (I think it was at 33L/100km when I got in it:shock: ).

on the run to work this morning it was about normal until I started giving it a bit. I'm sure the first couple of weeks will be expensive.:badgrin:

Get your car tested. It may be running very rich.


ok... where would you go to get your car tested if it was running rich?

and how do you check your O2 sensor?

the misses is getting 560-580 around town to a tank of 91 ron with her '00 TJ 3.5 auto, including just putting around and the odd rev or 2 when she needs too.
that mileage is going to and from work, which is 35 k each way, and can take 45-50 minutes some days, to and from juniors school, and the other usual 'mums taxi' type of stuff.
she says that the second air intake that ive put on it has made about a 40 k improvement around town too, so maybe they are a bit restrictive in the air intake??

*edit* BTW, it's a stocky other than the intake too.

Well i used just under 2 tanks of fuel over the period of two days which we done just a little over 1500 kms

i always thought cruise helped lower economy, but ive been experimenting a bit..

fill up at the same BP Servo with ultimate (makes no difference, yeah, i know.. i just use it) and drive about 60 ks with 99% highway driving with cruise on returns a reading of around 9.8L/100ks..

do it without using cruise and trying as hard as possbile to get it lower and its down to 8.2 :confused:

regardless, im still happy with the economy for a big V6..

depends how flat the road is i guess. i mean if you have little rises and stuff the cruises steps on it to keep it at 100 or watever whereas you might just hold it steady when your not using cruise which would use less.

Filled up at Mobil, West Gosford, NSW and arrived at Shell, Billinga Beach?, Gold Coast QLD 789km later on ONE TANK. Fill up cost me $76.02 for 66.74 litres of 91 unleaded.

I turned the air con off but left my windows up when I reached Tweed Heads and sat behind a semi trailer as I was starting to get a little concerned as the range to empty had read - - - for sometime and the fuel light was permantely lit. But it was getting too hot so I switched it back on and hoped for the best. Other than that brief period, the air con was on the entire journey. I did but at times exceeded the speed limit with one full throttle overtaking manoeuvre (was no overtaking lane and I wanted to get past) so I was by no means driving to maximise fuel ecomony until the last stages when I wanted to avoid running out of fuel and make the Queensland border. I found driving at 100kph resulted in the best economy and being a Monday, the traffic was pretty light so there was minimal interruptions to my cruising speeds. I am very proud of Maggie.:D

I'm my bog stock TL ES, I managed to get from Adelaide to Mildura (about 400km) using only half a tank of fuel.

Still have another 400km to go according to the trip computer... :shock:

Yeah I know you dont drive the ralliart now, but the situation is cruise control uses more fuel. As you can let go your acceleration padals on your reaction compared to the cpu. The cpu for cruise is only trying to maintain that speed through out.

Pluses is you gain fuel economy minuses is that is more stressful driving. A give and take situation.

Funny that I find this quite true, at a certain speed like 100 suits the car best as you not pushing it too much. my 2.4L engine gives the same results as yours reaching 780kms or so with enough to go actually just touching 800kms but wont push my luck. I find that when I was on stock 15" wheels I get even more fuel econonmy! reaches 800kms easily. But I love the look of my 16" rims. lol

Hi bain I have a 2002 model TJ with the following modifications 3 inch exhaust and lowered suspension on 17 inch wheels she is a four speed auto and with easy going on the pedal I get usually 800 k's to tank driving in to Orange and shoping and work I live 40'ks out of town so I drive each day into town mind you I am very light on the pedal :badgrin:

2.4L TE. I get approx 380km on a full tank. Thats town driving (to and from work) and saturday night crusing.

K&N pod filter. Zorst coming soon woo!!!

That is absolutely **** mate, check out your fuel filters and injectors for cleaning and replacing filters. The only time my fuel economy is ever that bad is when I am running rich on fuel using Barry's kit but was normal and even then, it goes over 400kms touching 500.

When normal I get minimum of 500-600 on city driving and 700-800 on country roads.

Yes talking about 2.4 Spec, have it check, there is something wrong getting under 400kms. I am using K&N penal as well.

I'm using a pod, but it shouldnt make that much difference. I thought it was bad, I do have a heavy foot.

Can you tell me what to check? And what I should be looking for. Please.

Have your injectors checked. decarbonise the fuel lines in necessary, and change the fuel filter. Check your Engine oil, use semi syn as minimum grade.

ensure your tyre pressue.

Cheers!

Tyre pressure was checked and adjusted night before last. What type/rating oil do you recommend. I dont mind spending money providing I get top quality. I take it decarbonising the fuel lines and checking the injectors needs to be done by a mechanic and is not something I can do in my backyard?

might wanna check your oxygen sensor
sounds like its not doing its job right

To what am I looking for? Would the new air filter have a bearing on it?

For Engine oil there is a whole list mate. Set abudget on what you willing to spend.
Example 20-30 dollars would be semi syn grades where you can get Castrol Magnetic, Shell Helux Plus or econ, Pentrite semi synthetic etc... where is $40 and above you can go fully synthetic.

Main thing is to check your O2 sensor as well as Rob suggested.

Cheers!

Well i broke my personal best for kilometres out of a tank since i did a engine rebuild.. I got 416kms..:P

Well that makes me feel really good. with more tweaking on my magna and the haltech i have now worked out some averages.

City Driving with some free way driving - average 450km per tank
Long distance - Perth to Albany - average speed 115 km/hr hilly territory - 600km per tank average 10L / 100km
Long distance - Busselton to Perth - average speed 115 km/hr straight roads - 8.5L / 100km didn't use a full tank so still going.

When we built the engine we only run 8.3 : 1 static compression so really suffers on the fuel economy wish I had now bumped it back up to 8.7 or 9.0 : 1 for more off boost economy.

This was all done on either BP Ultimate 98 or Vortech and was done in the last two weeks whilst I was on holidays. Gotta love overtaking :)

Main thing is to check your O2 sensor as well as Rob suggested.

Cheers!

[I think i need to get my o2 check as well, how do you do it ( im a n00b) or does it have to be taken to the mechanic?

im driving a v6 altera TE 97 model and im getting 350km for full tank
can some one please help. - how do I check the o2 as well as change the fuel filter and get it decarbonised.

what's involved and roughly how much will it cost would be great thank. :shock:

oh by the way it's auto and i drive like grand ma.

From 11th of december 2005 till 10th of december 2006 I travelled 17594 kilometres,used 1,928.38 litres of petrol(42 fillings@petrol station) which I paid $2,355.83.Average cost was122.1 cent per litre, average fuel consumption was 10.96 l/100km which mean that each 100 kilometres travelled cost me $13.38 petrol only. About 60% was city driving. My driving stile is rather agressive than grandma kind of stile, by that I don't mean burnouts or any other stupid behaviour on the road, just strong acceleration whenever possible.
Modifications are K&N panel filter, custom made intake snorkel, hiclone, VRX rear muffler and 02 series VRX wheels (which are on the market). Being 4 speed auto I am happy with fuel consumption. Have car for over six years, it has 199000 Km on the clock, servicing car by myself since warranty expired five years ago. Have trouble free ride(touch wood) since bought car.
Cheers,
Zdenko

Last time I checked, gand ma overtook me in her Camry. LOL

Dont assume old people drive their cars slow.lol

Anyway, Do the following first, change fuel fiter, decarbonise fuel lines, change your engine oil if you have to, perferably a semi-synthetic oil blend at least.

And see how is your mileage.

If its still bad ask for the O2 sensor to be changed.

Just bought a 2004 AWD about a month ago, and have started reading this site. The question of fuel econmy is a good one which i put to the test recently.
Having packed the wife and kids, camping gear (on roof racks) and absolutely filling every corner of the car we took off for the north coast of NSW. We averaged 9.5lts over a three hour drive. Next we dropped off the camping gear and racks in Forster on our way to the ACT, we got 8.2lts to Sydney and got down to 7.3lts between Syd and ACT. This was sitting on 110 most of the way with the AC on. All fuel results were the same on the return trip. The car ran faultlesly the whole way and is awesome to drive, much better than my old TF and much better fuel economy too.
One annoying note the fuel light comes on when ive got 18lts of fuel left in the tank and a range of over 130ks to go. A bit of overkill i think.
Great car, great drive

Forgive me for the ignorance, but how does one decarbonise the fuel lines?

How the flipping hell do you get those figures with an 04 AWD!!!! :shock: The best I get with my 04 VRX AWD is 9.4lt/100kms on the open road, and thats with the cruise set at 100kph.

Using cruise uses more fuel. That could be one explanation.

Only thing i can think of is that the drive from Sydney to canberra is flat, good quality roads and little traffic. I just put the cruise on and steered, very boring but the car just got in a groove and i dont think it changed gear once 2.5hrs.
Also checked it agianst the fuel amount used and it was right on the money, i did notice a big difference in driving north of sydney where i saw mid 8s, alot more hills, crappy roads and heaps of traffic.
I know it seems hard to believe but i double checked everthing.

eh?

i dont think it does. if anything it uses, well, not less. but as opposed to an unsteady foot, and fluctuating throttle openings.
