Fuel Consumption

[Wolf]

Hi

I've been running the Supe on around 18-19 psi for a couple of months now and the average fuel consumption is 12 mpg - is this about normal for these or is it conspicuously high??

At this rate I may have to sign a liver or kidney over to Shell....

round town, all motorway....what driving pattern please?


Auto or manual, AC on or off?

[George L]

12 mpg, BASTID! :eek: Going to kill me a Supra is!

[Wolf]

It's a J spec Auto with 90% of the time spent in "spirited" country road and A road driving.

AC is on a lot...

Must be fairly spirited driving, im getting 18.93 mpg in a modded uk spec, A and B road driving.

The good news is you get about £20-£30K for a kidney depending on condition

You're either a total nut case or you have a bit of a problem. I've run mine for a year now with up to 1.1bar, and get 20-22 normally and 7 on the track. I cant see how you can get 12mpg on average. Where do you live? Santa Pod?

[Adam W]

I run my Mk3 at 1.1. bar and get about 12-14mpg if I'm really going for it. Try filling up, going for a thirty mile motorwa cruise at 70 or 80 being as boring and slow as you can, and then filing up again. You can then work out your mpg and if it's less than 20-25 (depending on how slow you can make yourself go!) you could have a problem.

I've never really bothered to work it out before but now that I have I'm quite pleased.

My car's a bpu'd J-spec auto running 1.1 - 1.2 bar generally. My cars in daily use doing the commuting run and some fairly 'spirited' moments.
I regularly get ~ 220 miles to a tank full, (usually fill up before the light comes on - 60 litres approx) which I believe means I'm getting ~18 mpg...

[Steve Cargill]

I get about 300K's out of 50L in normal commputing (16-18MPG) and the best I've ever seen is about 21MPG

[Wolf]

I'll try driving down the motorway slowly as suggested and see what I get - what sort of problem would make it drink so much gas??

Peter

[George L]

Fuel consumption is awful, but thats what expect from a fsat TT I suppose?

[Steve W]

BEST EVER = 31mpg , 2-ways , on holiday down to Cornwall.
BUT, that was limited to 85mph MAX. and ALL motorway/traffic-free
A-Roads ! ! (ie. just about the most 'ECONOMICAL-ist' trip ever !)
[limited due to being with a Megane/family and Eng'Man' light
would come on if went above 3,000 revs !!!!! -not problem but
couldn't trust light otherwise !?!]

I find to/from work, NOT really booting it, local B-Roads = ~15/17.

Up-to Pod, 6/7 runs, back again = ~23/25 -ish.

Only De-cat though !

YEAH, it's thirsty, but, wadya' 'spect from a 300hp GT car ? ?
[with A/C, auto, Fat-Bast'-Driver etc.etc.]

[Chase]

What's the most fuel-efficient speed to travel at on the motorway? or any other road for that matter?

Is it highest gear with lowest revs? what about an auto?

Cheers

If it's that low are you sure you know if it's registering kms or miles. Mine reads kms but registers miles. Could be you think you're getting 12mpg (19km), when you're actually getting 19mpg. Just a possibility? :music:

:looney:

[Wolf]

It's certainly shows KM but I'll have to go and test it now over a timed distance to see if it's reading miles...

Could be that or else I seem to have the juiciest car here

I measured my mpg a couple of weeks ago - here's the info...

22mpg doing a fairly even mix of normal, fast, slow, town, mortorway, a-roads although I would say on average I was making "more progress" than I usually do. ;o)

('93 RZ de-catted exhaust, approx 1.2bar, hks induction kit, and 275&235 tyres).
