Hi guys and gals, i have a 02 sports 5spd tippy, i am ony getting 350ks to a tank, i dont drive it hard and thats all i am getting, WTF is going on here. Has anyone else got this economy aswell or is it just me? is there something wrong with my car it only done 55k If you have had this problem and has been fixed what did you do to fix it? All help is appreciated Thanks Timbo

I have a tj sports 03 tippy and get about 11 to 12l per 100ks town driving and way better than that on the highway so i would say that something isnt right mine has 74,000 on the clock i would start investagating as to what the problem is. :cry:

wow only 350K per tank. wat fuel u usin??? and ne mods. i use shell optimex and only mods a have is a K&N panel filter and exhaust and i get bout 600K per tank and 550 to 580 on normal unleaded and i have a heavy foot at times.

Have you actually driven the car that far? Dont believe the trip computer, its lying to you! Evil bastard little things.

I'm not sure why my fuel economy has been improving. when i bought the car a year ago was getting 13.5 City. Some of youse may remember my ranting of the heavy fuel consumption here....

....then July this year when I checked again it was 11.7. now its 11.2 for a month. Hwy = 9.2L. I haven't done anything to the car except changed the oil from whatever it was to full syn 5W50 in March so far due to the distance (lack of) that I drive.

can be many things that you could change to help your economy.... run a higher octane fuel for a while to give it a clean out, has your transmission been serviced properly and is the oil in there clearish-red? is your car serviced reguarly, engine oil clean, not black? spark plugs and leads shouldnt need doing this early, but is possible... tyres in good condition with proper inflation (should be about 36psi i think, give or take a couple), air filter clean? engine might need a carbon/injector clean? when excellerating, do you push the pedal halfway down or more when your taking off, or just a little bit (you'd be surprised how little you need to get off the line briskly) the further you push the pedal, the more fuel it sucks through.

I cant think of much more for now. all these things will help a little bit each, but not enough to give you 200k's i wouldnt think. :doubt:

Im pretty sure that most people with 3.5l autos have similar fuel economy(400-450), and it seems to be the 3l manuals that are mainly getting into the 500-600k's per tank.

thanks guys, off to repco to get oild and injecter cleaner

my 3.5L get me bout 600Ks on high octane and 550-580Ks on normal unleaded :D

I put fuel last night. I did 780 k's. I am driving to Brisbane from the Gold Coast everyday. On the motorway i am geting sometimes 7.7lt. with new transmission.

Mine- 3.5L TJ auto, about 540km's city, and and over 700km's hwy.
Like any car shorter stop start trips will chew the fuel. My friends BA XR8 auto gets up to around 24L per 100kms in stop start driving!!!!!!!!!!!!! So it could always be worse!!!

Haha my TJII 03 tipper auto get about 500k's out of a tank, I have 20Km of highway
and a 15Km hill climb just to get home from work five days a week. :cool:

bleh, im getting close to 600km out of 40L on pure city driving, hoping to get about 750km on the open road after a service, oh thats in a 99 civic by the way, lol it uses less than half the amount of fuel my verada did

Unreal isn't it. I also used to regularly get 5.8 out of a civic. But that's because they're 1/2 the weight of an AWD.

ive been having a look at 3rd gens that come into work to get serviced with trip computers and im suprised how much they vary..

one TJ 3.5 exec's avg. fuel was 7.9L/100km and ones was 18.2 :shock: most are round the 10.8-13.8 mark so mine is fairly spot on.. plus if i want good economy, ill drive sedatley, if not, its foot to the floor :badgrin:

*checks economy reading on trip compuer* 15.8L/100kms for this tank

oh thats in a 99 civic by the way

Very helpfull :D

I find that changing gears at 3k instead of 4k to redline usualy knocks off anywhere from 2-10L/100Km ,but i may have been acused of driving Ms Daisy lol

With the AWD i try to hold the revs between 1800-2000rpm during acceleration and then back off when 5th gear kicks in thus getting an av. economy of 11-12 with respectable acceleration.

for the manual mazda, it's also 1800-2000 rpm till 5th gear and av. fuel economy is 6.6l/100km.

is about 440km in a 4 pot TR manaul Bad? what size is my tank, if any one still has an owners manual.

i have a 2001 tj with 64000kms and get about 600km to the tank. has your battery ever been disconnected???? when this happen you need to reset the the trip computer to show that it is a sedan or wagon and 3.0l or 3.5l. not sure if that has anything to do with it???
