hey, just had a thought (fleeting thought it was) about how my fuel economy compared to everyone elses. I use around 16L/100km, which is worse than my dad's 6L V8 (I have a TT). Is this excessive in comparison?

cheers

very, i average around 10 to 12L/100 This is with alot of spirited driving.

Im sure if i drove sedately for a while tank id be under the 10L mark hehe

I did 748km off a tank with about 5l fuel left gauge said zero. That wAs highway v8 totally black air filter clogged cats and on 20's. And car full of crap!
Around town it uses the same as the 1990 2.6l magna 4cyl I'm driving at the moment and goes heaps harder

I'm not a loony but I do not drive for economy. I accelerate moderatley and am always pressing the go pedal. I could easily save 1-2l/100km if i tried

My V8 gets around 12-13L/100km in the city and as low as 8.5L/100km on the highway depending on speed etc.

16L/100km is crazy bad, I know two different people with lightly modded 1J's both making over 200rwkw that get better economy then that.

If your driving the car hard accelerating hard braking hard etc then 16L/100km sounds fine. I found simply by changing my driving style I could easily get an extra km or two out of a litre over normal non 'fun' driving.

something must be wrong i'm thinking. although i do tend to accelerate hard occassionally. i always try to prevent hard braking though, never have the air con on and even keep the windows shut most of the time to improve aerodynamics ! I've taken the spare wheel out and only ever fill the tank half full so the engine doesn't have to pull as much weight. and i don't weigh like 200kg or something either !!

My first V8 was 12L/100km.
The current supercharged++ V8 is close to 10L. Its in the way its tuned using the Adaptronic ECU.

Michael you will probably find your oxygen sensor is due for replacement, my economy (TT) went from 11L/100 to 14-15L/100. I replaced the oxygen sensor and it went back to normal.

Out on the highway if I drive sensible and only really use a lot of boost to pass I get 7.5-10.5 L/100

I'm working out my mileage at the moment. So far the fuel gauge read today just under half a tank and my trip meter reads 360k's, and that's driving around giving it a bit of stick now and then, but most of the time normal driving. My guess is that I should get close to the 700k mark out of a tank of fuel quite easily.

Wow 16 sure is high haha!

I record my trips and over the last 3 months have averaged 12.81L/100 which I am happy with. I do a lot of highway driving and the occasional fang but usually economy minded. I have been down as low as 11 before - on a cruise which was interesting haha.

Also, probably a good idea to put your spare back in - it's not worth the risk for such minimal weight saving. Same with fuel tank - unless you are on a race track, 30kg of extra fuel on board really wont affect your economy.

Hope the O2 sensor fixes it for ya, and you can save some money with less fuel to pay for!

is there a quick way to check the oxygen sensor (or does the ecu think it's working fine? and therefore it doesn't pick it up in diagnostics?) i might see how many kms i can get out of 10L driving really economically (ie. little to no boost) if it's still around 60-70km, i'll take it in to...a good place in perth (hollywood joe, 've heard is quite good)

the thing is though, the chap i bought it off had it serviced every 5000km and had just recently been serviced. ever since i've had it the fuel economy has always been this bad, so surely his mechanic would've picked it up at leastone of the 5000km times...or maybe he just missed it the last service. i don't know what to do..

Serviced means serviced. Oil, filters etc.

If the owner never reported a problem, eg fuel consumption, then the mechanic wouldn't know to look for it.

yeah i suppose, they can't check everything i guess. day number two: never using turbos i'm as bored as hell, trying really hard to keep the engine revving below 3000 while still trying to accelerate reasonably.

remember these cars came out when fuel was cheap and no one cared about fuel consumption.... yet still they match most similar sedans, a V8 Holden of the early 90's used up to 25L/100km in urban use according to published figures, and still only made from 165kw LOL

yeah, also, i tried driving using no boost at all, and if i extend my trip computer out for the 10L, my fuel economy improves from 60km/10L to around 90km/10L. need to find a compromise i think...

Other than the O2 sensor it might be worth trying another ECU, if the Caps are leaking fuel economy can be effected.

I dont know how much I usually get ltr / km's but I know I get roughly 600 - 650km's a tank driving to and from work everyday. MUCH better than the supra which is roughly 400km a tank and not much less to fill up.

just making sure i didnt calculate it wrong...

480km to a 78L tank
480/100 = 4.8
78/4.8 = 16.25 ~16L/100km

for this run i did.

i've never tried finding out what it could do so i drained it out after changing my fuel filter, put in enough to get me to the gas station and reset the trip computer after filling it up.

might be worth giving it another go though. 1 trial probably isnt reliable enough. 2 or 3 times could give a better picture.

How bout just fill your car up to the point where the pump nozzle stops automatically.

Reset the Trip computer to 0.0km. Drive for whatever amount of k's until the fuel light comes on or petrol is too low for your next journey.

Fill up, record the number of litres it took to fill up to the brim again. Use that number and check the trip computer to calculate the consumption as it will be a whole heap more accurate then saying '78L'.

Spot on Aaron - but I would top upt the tank until you can SEE the level in the fuel filler neck (and make sure it is on level ground too)
Full tank to full tank is the only accurate way of figuring fuel consumption - anything else is just guess work.

Something wrong there Matthew - my JZZ31 gets over 600km per 70 litres mixed driving, with a little bias to open road

Don't forget you probably don't have a 78 litre tank, JZZ31's I think pretty much all have the smaller 70 litre tank. It would still be pretty poor to only get 480km out of 70 litres in a JZZ31 though.

Just measured mine, 18 lph

I know i need an oxygen sensor, but I have a blitz access ECU, is doing the caps on it wise? Or am I more likely to break it (or modify it badly)

Holy guys.

I average 11/12L/100km.

Running 360hp @ wheels. And that's with a decent amount of boosted driving..

You fellas need to go get tuned!

And Michael. Fill your car up, put your spare back in, use the aircon when you need it, and wind your windows down when you feel like it.

I was kinda kidding when i said that. I only fill her halfway up because i don't have the money at the time. i don't have the spare in cause it didn't have on when i bought it, i never used the air con (hardly ever) in my old car (a 1.8ltr kia), and i do wind my windows doesn't whenever i feel like it.. i was just trying to emphasise my really bad fuel economy.

There is nothing to tune on a stock car, nothing at all, not even base timing.

What computer are you running?

And does any one know if doing the caps on my blitz ecu will effect anything? (obviously economy)

Stock soarers run pretty rich. I was suggesting those of you upgrading in the future go get some form of tuning apparatus and get some fuel trimmed.

Sorry Michael, I thought you were serious haha. Some people literally do all those things..

i've been scraping over some speed humps and i think i've cracked parts of my exhaust/ cat. I'm assuming this can contribute to bad fuel economy? (as well as drop in power)

michael, your ecomony is crap, I get 650kms per tank in my V8 and a friend gets >700kms in his TT. We both have the "egg cup" BFI mod to the airbox.

where does your temp gauge sit? should be in the middle, if you are running cold (change the thermostat)fuel consumption will be up on a cold engine. It should get up to full temp in a couple of KMs driving.

my temp gauge does sit in the middle. your friend sounds like he doesn't spend a lot of time on boost if he gets better fuel economy than the v8. unless the tanks are different sizes

worked it out more accurately now,and it seems not as bad as i thought. only 14L/100km, i'm thinking of getting an ecu, any ideas?



Try an ECU reset first (check the "Handy Tips" forum)
Although if you have a number of mods or a boost controller it may be running richer naturally.

Personally i average ~17L/100km but thats just because of the tune and the that has been done to it.

To be honest 14L/100km is not a scary figure for a twin turbo Soarer no matter how much of a grandma you drive like.
At the end of the day the 1jz loves to drink so just keep it's supply healthy. =P

Guys I can do ECU caps for $50 + postage, that's if there is no leakage. I also have a pretty much brand new O2 sensor for a TT for $125+post.

David my friend Tra went from 13l/100km or something like that to the 11l/100km above with an ECU with new caps.

I get 11.5/12l/100km, pretty much all city driving.

That means send me your ECU and I send it back by the way...not just send you the capacitors :-)
