Just wondering guys, I saw the magna section has a thread about it.. I know theres one about the fuelconsumption for the 380 but i thought i'd make a new one.

I do mainly city driving - average speed 40. Fuel consumption 14.5L. Making just 410KMs on a fuel tank whether 98ron or e10.. Using 60Litres ( computer says)

what do you guys get?

Mines a 2007 series 2 vrx

thanks guys.

Series 1 base model manual, 98RON, 510km/60l when 90/10 suburban/highway, up to 650km/60l if the other way around (10/90 suburban/highway), overall average around 550km/60l, and like Braedz I give it plenty of WOT!

I tried driving like a granny, setting cruise on 60kphs LOL, can't be asssed to though, i give it alot too. maybe thats the reason im getting 410ks a tank.. 50kms of tiptronic and high end shifting. ;s

Funny this has come up.

I've been comparing ranges with my kids' cars that I am driving ATM while mine is repaired.
All hwy driving and exactly the same route.
Holden Vectra 2.2L- ~ 550km
Toyota Celica 2.2L 6th Gen ~ 600km
My car VRX Series 2 with Xede - 690km

Haha... Chip Torque Exede. It's a piggyback and I get 8.6L/100km with normal driving and the occasional squirt (WOT). I could get better than this - I've seen 7.9 but I can't be bothered driving like Grandpa for a full tank - that would give around 730km.

$1500 with dyno tuning. Some say not worth it, but for me it obviously is, as I do a full tank - 650km, sometimes more, per week. You get an extra 7kw as a bonus.

if you are worried about fuel economy 20s are probably not for you. i get 350-450 kms to a tank. with 20s. extractors, and (very) straight through exhaust. grandpa driving yields about 13l/100kms (according to the trip computer which we know is woefully not accuarate) Jamie style driving yields 16-18l/100 lol.
still get down tio about 8.5 on the freeway however.

Alright so mine ATM, as is with the 20's on around town ill get between 530 to 550 k's per tank. I can and have done Sydney to Melbourne on a tank with the 20's on. JUST. So 870 k's. With however with my stock 17's the best i ever got and i shit you not was 1002 k's till i literally ran out of juice and had to call my brother for help, that was a full tank from Sydney to just before Albury (VIC border) and back home then to work the next day then broke down lol. 560 k's on half a tank i saw during my drive. That was when i was on my red p's and restricted to 90km/h on cruise. I only ever use shell's V Power 98.


Oh and do get the 20's instead lol. Fuel econ is worse but looks PORN.

Idk how you're getting 500+ in town? currently mines fully stock apart from amc stickers lollol
great grandad driving style will get me 460 with 98ron shell. maybe the new intake will get me that 40K more for 500k maybe?:badgrin::badgrin:

Like Richard (Knotched) I also have a ChipTorque Xede piggyback ECU. Tuned to run on 98RON. But Richard gets better fuel econonmy than me with highway driving coz his auto is doing only 2,200 rpm at 110 km/h where my manual is doing 2,900 rpm. With suburban driving we would be much the same, as a properly tuned Xede leans out the air fuel
ratios (AFRs) at wide throttle openings by quite a bit. If you plan to keep your 380 for many years (at least five) and you do plenty of km then fitting an Xede will be cost effective. But there is a strong rumour that someone has finally cracked the 380 ECU so in the not too distant future you might be able to get a re-flash of your ECU for around $500 rather that spending approx $1,500 on an Xede (including fitting & tuning).

Out of interest, what is the Capacity of a 380 Tank??

According to the brochure 67 litres.

But once you get down to about 7 litres left the fuel guage reads empty and the trip meter reckons your have 0 km range to empty.

So practically speaking the capacity is 60 litres.

That's all I have ever been able to pump in at one go.

First thing you should do is look at the simple cheap mods that have been proven to improve fuel economy and throttle response, not to mention sound.

The 90mm Galant intake snorkel, a less restrictive rear muffler and cut the end off the lower resonator.

i have a fuel receipt somewhere where i filled up 67.6 litres. Though i do remember turning off my car and the fuel gauge didn't even go down the slightest, it was that empty.

Also, when i did the 100k's on a tank the only mod i had done was lowering, standard air intake also. I had recently brought it so all intake and everything was stock. To date i have recently put back in the paper filter and only mod i have to my engine area is the 90mm Galant intake and stock (shame) exhaust.

Filled up at fitzroy in Melbourne. Drove the Hume to gosford 733klm. Cruise control all the way. Two adults with boot full of luggage. 36psi in the tyres. In excess of 40c all the way. Refill took 63litres.

Dont know. Never drop below half. Got a thing about running out of fuel. Unlike my dear missus!

flyboy
22-04-2011, 09:38 AM
I refill when the range just gets to 0km.

Around town 500km, trip computer average speed 30-35km/hr.
On the highway 700km, trip computer average speed 105-110km/hr.

67 litres is the useable capacity. Aircraft also list fuel capacities as "useable fuel". The tank holds more than that, and the rest is considered "unuseable" because continuous fuel supply can not be guaranteed in all environments (ie if you car is on a steep slope). In reality, normally the car is fairly level and so more than the 67 litres can be accessed.

I'd probably guess the unusable fuel in a 380 would be between 2-3 litres, so that's why people have managed to get up to 68-69 litres in.

I know that when the trip computer range says 0km, I still have approx 7 litres left and could hence do 50-60km around town or 100km on the highway. But I don't take the risk - running out of fuel is not good for you vehicle's fuel system components and catalytic converter.

Running out of or really low on fuel is not good. You are dredging up all the crap from the bottom of the tank. This will eventually stuff things up like your injectors and cat. On the subject of crap in your tank, running a tank of E10 (ewwww yes I know:naughty::angry::shock:) will help get the moisture out of your system. I used to put some metho in too.....ages ago lol

Sorry but I will have to call BS on this as I don't believe that a 380 could sustain an average of around 6.7L/100K for 1000 kms. How much fuel did you put in when you filled up? I have tried some economy runs and find that this is unachievable, esp on cruise as it is far less thrifty than an educated right foot. Is there anyone else out there that thinks it can do 6.7 over 1000 k ? I would be interested to know.

Knotched
22-04-2011, 03:25 PM
67 litres, useable, eh?

That's good to know. The most I've ever put in is 58L so I might run mine to empty (that is; indicating 0 range).

You will wreck your electric, in tank fuel pump.
They are designed to be immersed.

Though it will take a few times, not just once, you will need to thump it to loosen the bearings duue to bearing migration.

Very common remedy by RACV road side assist...just thump the motor and shes away until tank gets low again...

Would only do any serious damage if you did it lots of times or if you didn't rectify it immediately (ie left dry for ages).

1. Like Blackstar said, not good for in tank fuel pump.
2. Seals in the fuel system are not lubricated, can go dry and crack.
3. As the engine starts to get starved of fuel and begins coughing and eventually conking out, the fuel mixture alternates between super lean and super rich as the fuel pressure fails and the ECU is wildly trying to fix. As a result, quite often raw unburnt fuel goes down the exhaust - and the cat can get very, very hot as a result.
4. Detonation if accelerating hard at the time of the starvation due to lean mixtures, but wouldn't last more than a couple of seconds so wouldn't do any real damage.

I don't really buy into the "crap in the bottom of the tank" theory ruining your injectors... That's what a fuel filter is for, and the fuel sloshes around a LOT during normal driving, so it's all mixed in rather well anyway.

I can get over 500 around town, my average speed in Canberra is in the 50's.

I don't see how 1000km's to a tank on the highway is possible but I think I remember reading about this before and there was a pic of the distance to empty readout showing over 1000?

Yeah but that is how you stuff up your in tank filter with a whole lot of crap. mind you fuel is a lot cleaner these days. Perhaps you have managed to mix fuel and water by sloshing around in the tank?

Sorry mate i dont recall how many litres it took to fill up as my brother brought me a half filled 10 litre jerry can of fuel (have no idea how many litres was in it but fuel light was still on when i started it). All i can say is i filled it up, drove it at 90km/h on cruise control all day, had lunch near Albury before heading back home to Sydney, i'm very sincere with this and those photos are of my trip because i too was very surprised with the fuel economy as well.

At the end of the day I'm not going to twist anyone's arm into believing me, that is of course up to you to believe it or not, obviously your not convinced but mate, I'm VERY honest here mate, i really am not into making stuff like this up if it didn't actually happen

Move aside Prius !! We have a new contender! I do believe you are honest in what you say and if you live on the south western side of Sydney then the kilometres travelled would be pretty well spot on. My only issue is I often drive to economy as a challenge, and have never achieved anywhere near your average on a trip. I have done the 90mm and lower intake mods and have a straight through redback muffler and run my tyres @ 40psi. If you have done this then your ECU must be different to mine!!

as stated, only mod was it was lowered, stock intake, stock filter stock everything and have always ran 40psi in my tires, i live about 2 k"s from the hume highway in Liverpool so it was straight onto the Hume highway so there was no stop-starting driving at all.

TJ 3.5L - gunning it around town for 300 km - av = 14.5
90 KPH cruise = 6.3 - 6.7 (inst fuel consumption)
100 KPH cruise = 7.2
110 KPH cruise = 7.5

On a non stop run, with no stops or traffic to be help up by, or zoom past, flat road, cruise on, I think kif's claim is achievable. So you would use 67L in 1,000 km. Still some fuel left. lol

Big difference in fuel economy between the manual and auto equipped 380's.

The auto is much faster in the 0-100km/h and uses a lot less fuel.

From what I've seen there is a huge difference in the rpm at 100km/h, you've got to expect it to use more fuel simply on that basis.

Auto at 100km/h = 1800 rpm
Man at 100km/h = 2800 rpm


That's a huge difference.

So one tank Liverpool to Albury? Well done. Coming from a 2001 220kw XR8 (That's a Ford V8 for anyone that doesn't know) that is lucky to get 400km around town from 60 litres (yet got me from Melbourne to Yass, with enough juice to get me home, ie around 10.xxl/100km), I'm now looking forward to a long trip in the 380. Even if I only achieve 8s or 9s on the highway, it's still way better than our other car (Ford Territory AWD, averages around 13l/100km on the highway at 110km/h).

Too bad Mitsubishi stopped producing these cars - those sort of figures would go very well right at the moment with the price of fuel and the focus on fuel economy.

I think a lot of people in this thread are missing the point that kif was travelling at 90km/h when recording that fuel consumption figure which saves quite a bit of fuel when compared to travelling at 110-115km/h which most people travel at on the highway.

Didn't know that, is the manual so high in the revs so it has power for top gear cruise control????

Travelling at 90km/h makes a huge difference to fuel econ, around 90 for a v6 should be the Optimal speed for econ, varies from car to car obviously.

Wow you should get a manual magna ralliart haha. I've been driving with much spirit around town (40-70 zones) and am still on 10.8l/100 after 250km, Amazing.

Hey Hayden,

I don't bother trying to work out how good/bad my car is on fuel anymore. I just fill it up when it needs it lol

EDIT: the average consumption readout says 10.8 at the moment though. Probably the best I have ever averaged. Usually it hovers around 12-12.5 i think.

I'm getting pretty bad economy Lucky to get 330 - 350kms on a tank and I can't figure out why. If I even average out what I'm reading on the thread I should be getting at least 400 - 500km on a tank, and by the sounds of it you guys are more rev heads than me :P . It's a daily driver and hard to give it WOT during peak traffic but I do give it stick from time to time. I'm hovering around 17 - 18L on the gauge which certainly isn't great.

I'm beginning to wonder if there something fishy with the car or if it's purely because I city drive daily. Any ideas on what I can look at during next service?

Car has done 97,000 to date. Got the car when it had about 50,000 on the clock. Since I got the car it's been doing about that per tank so I never gave it much thought but now with petrol prices being like gold I'm a little more conscious of mileage. To put it lightly it does no more mileage than my old 2L impreza and that sucks.

But if you have not got the 90mm intake I would get that pronto as I got a 10% gain in econ off the bat, also inflate your tyres to 38-40 PSI in the front and 42 in the rear for a little more savings in econ if you are running the stock 17' rim

I'm a Parramatta local I'll check out the meet threads. I did get the 90mm intake and it's on there. Didn't notice much on economy side but pretty sure throttle response was much better. I am running stock rims so will look at checking my typre pressure. Car's due for service in about another 1000km so was thinking of getting mechanic to check a few things out like sparks, and anything else fuel related.

i think this whole convo is a little blurry... to not make it blurrier lets set it straight guys - average consumption is heavily dependent on the average speed - so before you say "I am too high" or I am too low on fuel" check your average speed... my 380 does around 13.3l/100km on average speed 35km/h over a week, 15l on on average speed 30km/h over a week, 16-17l100km on average speed 25km/h over a week, and much better when driving faster around 10.2l/100km on average speed 40+km/h over a week of driving - it also makes big difference on the same route driven in the peak on off peak - school holidays etc.

If you averaging more than 15l on average speed 30k/h than i would think there is a drama somewhere but otherwise i wouldnt bother too much - its V6

i like this post.
im not complaining! that 18+ figure is using the car to work and back which is a 4 km trip with four sets of lights where the posted speed limit is 60. so average speed is quite low.
another thing is tyre size... as most of us are no longer running stock wheels/tyres. - in L per 100kms there are two points how many litres. and how many kilometres are in your recorded 100. i know that my rims/tyre combo is larger than standard so my 100 kms is almost exactly 100 (a stock car is about 95 as far as i can tell)

oh and VRX one idea chris and I (380ftw) came up with for the poor economy on my car is actually a lack of back pressure in the exhaust. since that was about when it started performing differently from standard cars.
unfortunately i cant identify which part as i had extractors, hi flow, and dual mufflers all installed over the course of a day. plus all new stainless piping for the whole lot. (larger than the standard pipe if i remember correctly - ill dig up the receipt later haha)

These things have 5% speedo error from factory (check it against GPS), so at 110, you're doing more like 103. Just thought I'd throw that in .....

Hi it's not speedo error it's the size (diameter) of tyre - bigger the tyre slower on the speedo and also smaller the faster.

Its not a problem as explained in the post before tyre size affects the speedo reading its quite simple and can be fixed with a different tyre diameter. Manufacturers do this on purpose to give the motorist a buffer

I've had my 380 for exactly a year now and the most I ever got was about 380ks. I have been averaging 350 per full tank with Shell V-Power. It was costing me too much so I decided to sell it.

However, 2 weeks ago, I tried Magnatech oil instead of Penrite and also changed my sparkles for the first time. I used NGK Platinum ones. Now my car is doing 500km a full tank. I seriously don't understand how new sparkplugs and new oil can make such a massive difference, but it has. My car has only 54,000kd on it and is in top condition.

Unfortunately, the car is sold and the guy is coming to pick it up in 20 minutes. I am now regretting selling it but now I have a chance to get an S3 instead of my current S2.

hi Guys,

VRX380 - check you average speed also to cross reference with the fuel consumption. I am usually perfect on the long stretches but City driving not so impressive.

Had my battery done on Wednesday - it just died at 5pm. so as I had my computer reset and i checked my fuel consumption back home... not impressive at all average speed 22.5km/h with 19.9L /100km... but considering walking speed its just cool - i am doing about 14.4l/100km over a week time - 80%city with the rest on the weekend a bit faster travel.

Just filled up - 426km for 55 litres, average speed 46km/h. 12.9l/100km (dash told me 13.0, so pretty close). Thsi was a tank of vortex 95, and I just filled with E10 to see if there's any difference - first ever tank was 12.8 on standard ULP, so will be interesting to see the differences, and the route to and from work has only slightly changed, so that should make little difference to the results.

Nice drive down on Cruise Control most of the way - adjusted so GPS was reading the speed limit - ie 110 most of the way, with speedo showing about 117. Speed check overhead radar just south of Wodonga corrsponded exactly with GPS.

The result from trip computer was 9.1 l/100k at average speed of 101.7 kmh over 632 km. Of course the trip computer doesn't know I am running LPG, where the actual full to full results gave 10.5 l/100 - 16% higher than petrol which is better than I would expect - usually in my mind say LPG 20% less energy per litre than ULP.

First half of trip - lunch at Gundagai - indicated 8.8 l/100, but in later I had some "finger" trouble with Tiptronic on long down hill run and left it in 4th for a long time afterwards - dumb!

Will be more careful on return run next week! :)

GPS vs Odo pretty good - ODO about 1.5 % more, compared to to speedo indicating 6% high

Also a question, I've been using insnt fuel computer lately and when I don use the throttle at all, I still get 2.2-2.8L ? Is that normal?

Mine is currently sitting on 397km travelled and 50.7 litres used for an average of 12.7l/100km. Wonder if the new 19s will affect it (rolling diameter is the same as the 17s I had, but 19s are heavier)?

I remember when I picked the car up, it had a travelled distance of 5000km (ie hadn't been reset for a while), and average fuel showed 11.3 - must have been a real grandpa driver.

I've seen mine in the 20's around inner Sydney where we live. Especially if a lot of CBD and back (4k round trip) in peak hour with the A/C on, so some ~9 on a "grandpa" drive down ther freeway is a pleasant change!

In regards to throttle off the lowest I saw on "instant" was about 0.3, but only when using tiptronic back to 4th to hold speed on long down hill runs. As the V8's are on at Winton this week there was lots of police prescence on the Hume!

Back to Sydney from Wang today. Same procedure with cruise set for GPS to be at speed limit.

Trip computer said 9.3 l/100 over 642 km with average speed of 104.2 - we had a good run with little traffic!

I am on LPG, where fuel added/used (full to full) was 77.25 litre, giving 12.05 litre/100 which is worse than on the way down there or an average of 11.4 over the entire journey, compared to the trip computer average of 9.2 over entire trip - or a 24% penalty for LPG energy density compared to ULP - close the the truth I think!

I used to park my car on the steep driveway of a friends place, every day, and soon noticed the angle was throwing my nice economy right out. Regardless of where I was in the current tank, I could never recover that loss fully. So I parked on the road instead and never saw that again. It was showing that my fuel was running out faster than it was, so I guess the fuel sensor is near the front of the tank. Could be a similar thing that you're experiencing.

yeah i think so too, but the way down, (obviously downhill) i seem to recover it, but the only reason why is i throttle for less than 1Km all up then 2-3km with no throttle so...

and i realized why they weren't picking up.

Cruise control on most of the way with stops in Gundagai and Aubury, filled up at Kalkaloo just outside Melbourne which is 638k's. Still had just under 1/4 of a tank left, trip computer said I still had 90km to go before empty. Instant fuel reading stayed steady on around 8 l/100K the whole way.

My average l/100K is exactly 11, I haven't reset it for 6 months, that is mostly Canberra driving with 2 Melbourne trips and a few coast trips. Not too bad I reckon.

Have been driving my TL manual for a few months now and it has settled around 11. Average speed about 40. It seems to vary alot at constant load, from 6 to 9 at 80 in 5th, level road and constant speed. I think ignition is weak and am looking at earthing upgrade and replacing plugs.

And I usually fill tank when it has shown light and put in 55litres , so about 550kms per tank.

Does better than mine..

Ended up with 15.4L per 100K. 39.5KM average speed. 1/5 WOT. 91RON fueled. 394KM done and filled 60.4 L.

I really think i should reset, do a hwy trip and not reset it. whenever i come back from a big long trip, fill up to full, average fuel sitting @ 10.5l, same driving style around the city, i seem to get 500+KMs. 395 is lame.

I put in 61.1 litres today (display showing 10ks remaining - haven't seen less than that), at 601 kms. That's the most fuel I've put in, but I once got 614kms from a tank (which was also with 61L). And this, today, is BP 95 which is all I use now.
Just for trivia sake, my best ever economy was 9.43 - and worst was 12.78 (all motorway driving, no city or heavy traffic, etc).
