Hi all!

Just wondering what other TJ AWD Sports drivers are getting for fuel economy?

I do mainly driving less than 60km/h and always have had 14-15L/100km and now it's creeping up to mid 16's!

This is with regular unleaded - with premium it seems slightly better (about 0.5 L/100km)

while mine is a KL Verada, its also AWD

i filled up today, and the trip computer was telling me 11.2l/100km average.
i do about 50/50 city vs highway last week.
i didnt have the aircon on much at all last week either, so that helps with the econ too.

interestingly, when i calculated out kms vs actual fuel put in, i got 10.7l/100km - so the TC was reading a little high, as i put in less fuel than the TC said i had used.
(completely stock engine wise, not even a KnN air filter!)

hope that helps out somewhat?

I've found my trip computer to be a bit discrete as well. Last time I filled up the comp said 13.1L/100 but I found I'd done 12.5L/100.

I have a KW GTVi AWD and average around the 12.5 - 13 lt per hundred....

Mostly stop start type driving with average speed around the 40kph mark.......

Hmmm... thanks for your replies - looks like I have high fuel consumption for some reason...

I don't drive very aggressively... perhaps the oxygen sensor or something is not quite right?

I've had it serviced regularly - perhaps I should point it out...

Does anyone know why the reported fuel consumption and the actual fuel consumption is different?

The reported fuel consumption is a load of rubbish...

When I bought mine I researched and the AWD GTVi was quoted at 7.5lt per hundred or close to that.........

I flew to Coolangatta QLD and drove back to Melbourne same day.....2 guys and no other weight and best we got with cruise running 110 most of the way was 9lt per hundred........

thats weird. I drove to qld, car loaded to the hilt with gear, wheels way up into the arches, got 6.9km/100 all the way there

Haha - I haven't got a snowflake's chance in hell of getting such a low consumption even on the highway. Mine is more like 10L/100km (according to the display) :shock:

Anyone had really bad consumption that they found a fix for?

Yeah, my AWD does anywhere between 9-14 l/100km on unleaded and up to 16l/100km on lpg if I don't use the a/c. With the a/c petrol can be as bad as 18l/100km if your not careful. & the only way the AWD can match it's published fuel values is when it's doing nothing else but going straight at 60km/h, downhill & with a tail wind.

I was rather disappointed with MMAL that they've lied so outrageously on the fuel consumption of the AWD, afterall this was made in australia and were supposed to lift the co's profile & keep it's factories going. Well it kinda reflected the culture & lack of professionalism thru the organisation, so they probably deserved to closed down. Not that other car manufacturer's don't do the same but there's a gulf between the published Hwy numbers and the actual Hwy numbers an owner of the AWD would get.

Yeah, to fix the bad consumption - I've parked the AWD in the garage to drive the other car which has an engine half as small and weighs half as much, so the fuel economy is 1/2 as thirsty.

thats a bit harsh dont you think?

Highway speed is considered 100km/h, if you had've been doing 100km/h you probably would have found yourself closer to 7.5. I've run 7.6L/100km in the Verada before, don't see why once your up and cruising the AWD's would use much more.

G'day,
Have a VRX AWD I average around 12.5-14.5l per hundred around the city. I do live in a "hilly" area which has a impact and most trips are under 15 minutes long. Note the lower side is when the boss is driving........ which I don't get as she "loves" the power and the VRX exhaust note :shock: . On the highway very different story constantly manage return trip down the coast and back of 8.5l per hundred, and out west (over the mountains) to the in laws average around 9. I was up around 17-18l in the city but the o2 sensor was not plugged in (so much for the 100 point inspection) fixed second week of ownership.

I am hoping this is the problem mine has - did you find this out yourself or did a garage find this for you?

DAMN!

some of you AWD owners get GREAT economy out your cars!!!!
the best i have EVER gotten out of mine is 9.8L/100 and that was driving the nicest i have EVER driven the car, gently accelerating away, cruise controlling everything and no / very little aircon.

BlackAWD - it could be the o2 sensor a mate of mine also suggested the AFM as well.
i found that a bottle of injector cleaner through the tank helps a bit with the economy factor, but not much - and its not really worth the 12bucks or so a bottle to save a maybe a total of 5bucks over the course of a tank....

keep your tyre pressures correctly inflated and checked that also helps as well.
i run my tyres at 36psi (cold) and check them once a week.

Thanks again...

I think I will need to get my car looked at...

Any recommended garages around Kew (VIC) - I have taken my car to Essendon Mitsu since it was bought - nice people - but I am not sure they are fixing the car!

Anyone have experience with Heidelberg Mitsu - or any other good garages around here?

Thsnks!

I am hoping this is the problem mine has - did you find this out yourself or did a garage find this for you?

Found out by the lovely "Egg Gas" smell that was extra strong to the pregnant wife at the time. That told me busted O2 sensor & or Cat convertor. suspected the Cat was gone due to previous owner sitting in car with engine running at idle alot. Took back to Mitsu dealer I bought the car from and they found it wasn't plugged in. Was "unplugged" accidently by the previous owner taking out lights radios and sirens etc wish they just left them in :D

My misses averages around 14ish for town driving which is normal.
We have had it down to low 8's on a long country drive but usually round the 9 mark.
I know the TL/KL onvards software was updated to give it better economy that the TJ/KJ's.
I wouldnt theink there would be much wrong. You have to be really gental on the gas to get it lower than 14 to 13's.

Don't stress mate.

So was it plugged into the ECU end, which would register it as connected but not connected to anything at the other end, or was it completely disconnected meaning the car didn't even pick it up as existing?

i would think that it would 'know' that its not getting the correct information that its expecting to get.

so yeah, it would 'register' as connected at ecu end but not getting the correct info it needs to be able to operate correctly.

its safer to run an engine richer than lean it out too much, so it (i think the way it works - correct me if im wrong!) it will add more fuel to the mix to prevent it from becoming too lean as its not sure what the engine is actually doing.
the extra fuel in the mix adds to the fuel average figures at the end of the day.

I have a TJ VR-X so please bare with me...

I was returning an absolute best of 11.1 L/100k's combined city / hwy driving...driving as gentle as I could.

I accidentally disconnected the battery during a clean and had to get a tippy 5 speed computer "re-learn" at mitso..

Since the "retune" the auto is much smoother and changes gear a lot lower in the rev range...

My best since..... 9.6L/100k's city and hwy cycle.... absolute best on the fwy up the coast was low 8's.....
My worst 10.7L/100

Just my .02c

The AWD unlike the FWD will not venture in the 7's unless you going down hill with a tail wind......Have done trips to Geelong and back with only myself in the car for work and no other tools on cruise at 100kays and still it would not go below 9lt per hundred......

I can live with it cause I enjoy having AWD in the bigger car but MMAL and other makers for that fact have something to answer for when they publish figures re consumption that belong in a fairy tail book.......

I didn't realise the computer had to re-learn anything. I thought it just relearned your driving style?

I didn't realise the computer had to re-learn anything. I thought it just relearned your driving style?

yeah it learns your driving style - BUT it also has to relearn how to run the engine correctly so to speak.

when you disconnect the battery, the ecu has to relearn how to make the engine idle correctly (engines wear over time, and this is to allow the ecu to still be able to run the engine effectively when its getting older and more worn etc)

the most trouble you will have, will be the first day or two, when it willl try to stall on you when sitting at the lights, or with aircon on, or when turning sharp corner (power steering will 'rob' more power from the engine)

after that, its fine - if you do a search on ecu resetting, im sure there is plenty of information and opinion on it here :)

altho - when iv done the full reset, iv never had any of these problems others have, i can just get straight back in it, and it drives excellently and doesnt even hint at thinking about stalling in the first 10mins of driving.
its almost like it didnt reset on my car :)

I have a TJ VR-X as well

"According to the trip computer", i get an average of around 12 L / 100k's combined city/freeway driving, that's with the occasional booting though :)

geez i'd be happy with 9.6l/100 !!

Mine sticks on 11.9l /100 around town.

Mid 9's on the highway.

Going away this weekend - will try it out again!

Just an update...

This week I had a mixture of urban and highway driving - 13.1 L/100km - much better.
I think it is the short trips in peak hour traffic that really wrecks the fuel economy for me... since I like taking short cuts - i.e. lots of turns - i.e. lots of braking / accelerating...

Thats where the problem is; stop braking when you come to the corners!!

AWD FTW

Lol - I don't - that's when I step on the gas - I only brake if I want to dial up some oversteer or when I get to the lights lol

Around town 11.7L/100 and just recently on a 300km round trip returned 8.4L/100 and mine is AWD.

I have a 2003 TJ AWD. Normal city driving around Sydney gets about 14.5 L/100km. Country driving never seems to get better than about 10.5 L/100km. Too many short trips to local shops sends it as high as 17 L/100km.

In short, the AWD is definitely more thirsty than the equivalent FWD model, which can save up to 2 L/100km, in my experience. I still love the way the AWD drives, so I will live with the extra consumption.

I have noticed that there is a lot of soot over the back of the car after a while. Do they run quite rich??

Im averaging around 11.5 which is only 1l better than my tuned xr6t

Hi RHR,that sounds normal enonomy wise.

I have noticed that there is a lot of soot over the back of the car after a while. Do they run quite rich??

Im averaging around 11.5 which is only 1l better than my tuned xr6t

is that an around town average? or highway?

highway purely - it can drop below that MAGIC 10L/100 mark, but have to be nice to get it to drop below 9.5L/100km....

11.5L/100 is quite reasonable for AWD iv found.
my awd doesnt show up with soot over the back end - and i would notice.
maybe another issue causing your car to dump soot everywhere.

Geeze you guys have bad economy i get 9.5l even with the blower
