mikeb Posted December 3, 2004 Share Posted December 3, 2004 Well I am getting about 30-32 mpg on a tank of mostly motorway stuff. It too, would only do 18 mpg around town! Sounds like a Supra wouldn't be much worse than my current car then. Quote Link to comment Share on other sites More sharing options...
Kopite Posted December 3, 2004 Share Posted December 3, 2004 my MPG is all over the place. One week i got 406 miles out of a tank before the light came on.....week after i got 200 miles and that was with similar driving - mainly at speed limits with average acceleration with the occasional hammer down a slip road. The last tank i got 190 miles out of but that was all town driving! edit: decatted UK with Nur spec Quote Link to comment Share on other sites More sharing options...
Whitelightning Posted December 3, 2004 Share Posted December 3, 2004 During testing of Whitelightning in Germany, I managed to finish a whole tank in less than 1 hour. Speeds were a min of 100mph and a max of 186mph during this period (early sunday on the A2) not including running up and down for fuel stops on Autobahn, (slip roads only) The fuel disappeared in 55 mins. I really should not use the average speed to calculated mpg as there was very excessive acceleration which would have used much of the fuel up. However I covered 140 miles in 55 mins which could equate to 9.3mpg (140 miles / 15 gallons). Luckily I was getting the fuel tax free (22p/litre). (My friend in his Porsche filled up at the same rate I did with similar performance figures.) And my point is ? If you are getting 10mpg out of your Supra AND are not driving like this then I suggest a tune is in order. The downside is that I was forced to have surgeory after this Sunday morning thrash . . . . . to remove my smile !!!! Quote Link to comment Share on other sites More sharing options...
paul mac Posted December 3, 2004 Share Posted December 3, 2004 Originally posted by Whitelightning During testing of Whitelightning in Germany, I managed to finish a whole tank in less than 1 hour. that my friend is awesome, top respect, am i the only one here wondering about all this talk of fuel "economy" and thinking i dont give a b****x, i just stick the nozzle in and pour in the optimax, if i WAS bothered i would NOT have bought a 3 litre twin turbo Quote Link to comment Share on other sites More sharing options...
250horses Posted December 3, 2004 Share Posted December 3, 2004 I managed an entire tankful at under 3000 rpm It was boring but I got 350 miles to a tank - I reckon thats +26 mpg I normally get 19 mpg If I go above 80 mph on long runs I can almost see the petrol gauge drop So dude if youre worried about mpg, keep her under 3000 rpm, thus only running on turbo 1, and you will get 26+ mpg Trouble is....................... What do you do when a Saxo VTS over-takes you? Do you stay mature, calm and collected ignoring him; knowing you could piss over him if you wanted to Or DO You Smoke Him :devil: Quote Link to comment Share on other sites More sharing options...
Terminator Posted December 3, 2004 Share Posted December 3, 2004 Originally posted by geoffvalenti It all depends on how you drive it I suppose. you drive it sensibly all the time, you may approach the above stated level of economy, but then it begs the question, why do you want one in the first place? Well said. Whats the point of not using the performance just so you can get 25+ mpg. For a high performance 3L TT, 18-19 mpg is pretty good. If you are looking for economy don't buy one you will be disapointed. Quote Link to comment Share on other sites More sharing options...
carl0s Posted December 4, 2004 Share Posted December 4, 2004 y'know what... I've been preparing (eventually) to make a post to uk.rec.cars.misc regarding my observations on fuel consumption. It's become apparent to me that, the journey to Leeds (town/beeston/M621) from Manchester (Posthouse Forte/Airport) uses FAR less fuel than the journey back. Also, driving round town (altrincham) uses fuckall fuel for me. Perhaps because I'm not racing, and I'm happy to utilise the torque-convertor and stay in overdrive, 'cause I'm in no race and it works. But driving BACK from Leeds (same place) to Manchester (same.. airport), always uses a quarter (last quarter - £10) of a tank of fuel. I've contemplated whether it's an uphill / downhill thing, or whether it's emotional thing - for example, perhaps I want to get the fuck home, so I drive every so slightly (although unaware) harder on the way back. But there's no doubting it. The journey there can be made on fuckall fuel, but the journey back always takes loads, usually after halfway there. hmmmm. I am pissed, so I might be chatting shit, but I've been ready for an enlightening discussion on these observations for some time. Just waiting for the right moment. Could it be air-pressure? But I'm getting the same both there and back. Maybe I don't start watching fuel meter 'til I'm nearly there, and the bit in the hills (yorkshire - lower air pressure?) results in less fuel consumption, so on the way TO Leeds, the guzzling starts to happen before I'm halfway there (don't notice it), yet on the way BACK, the guzzling starts when I'm nearly back.. when I'm looking for the result. Did I mention I sometimes think too much? I definately use less fuel going to Leeds than I do on the way back. Althought it seems to go badl once I get off the motorway.

mikeb Posted December 4, 2004 Share Posted December 4, 2004 Maybe when you leave the car in Leeds someone 'borrows' it and takes it for a good thrashing! Carl0s, your mpg figures from earlier in the thread seem pretty good anyway. Quote Link to comment Share on other sites More sharing options...

That doesn't make sense, I don't think. Actually, it might.. if it was an airpressure thing, but if it's an uphill/downhill thing, then it wouldn't make sense, 'cause the change of direction reverses the effects of the hilliness.

dangerous brain Posted April 15, 2005 Share Posted April 15, 2005 Hmm time to resurect this thread. My car has all of a sudden decided to empty its tank for only a mere 160 miles. Now I used to get around the 260-280 marker and my driving style and mileage type hasn't altered. the car did sit around not doing a great deal since chrimbo. Now it seems to chew through optimax like I have a fuel leak or something. It can drop a notch or two on the gauge in heavy stop-start traffic for only 5-7 miles. Its getting scary how quickly its emtying. My point is that it didn't do this before and now it does anyone got any ideas? Quote Link to comment Share on other sites More sharing options...
250horses Posted April 15, 2005 Share Posted April 15, 2005 Old fuel filter Old air filter Sticky brakes - try rolling car down hill in neutral Quote Link to comment Share on other sites More sharing options...

dangerous brain Posted April 15, 2005 Share Posted April 15, 2005 To be honest I need an oil change, I want to change the tranny oil as I'm not certain what type is in it at the mo, Dunno how old the fuel filter is. But this problem seems to just have arrived overnight. How do I check things like the O2 sensor or will I need to get it into a garage for this?

tbourner Posted April 15, 2005 Share Posted April 15, 2005 How do I check things like the O2 sensor or will I need to get it into a garage for this? Easy to do, measure the voltage coming out of the pin in the diagnostic port. http://www.mkivsupra.net/vbb/article.php?a=14 Otherwise put some cardboard or something against the exhaust whilst it's idling for a minute and it will be black if you're overfuelling.

dangerous brain Posted April 15, 2005 Share Posted April 15, 2005 if its been standing for a while its poss the rear handbrake shoe is sticking. try the hill test first Might just try that but i don't think thats the problem. It pulls away even uphill with no gas whatsoever. I think its a fuelling problem as the idle can be really strange. It'll idle at 1200 rpm for ages before it settles down to around 650 even when warm. If I could liken it to anything I would say its almost like the choke is permanently on.
