Nemesis Posted May 13, 2013 Report Share Posted May 13, 2013 I posted details up in the Japfest thread but wondering what the best fuel economy you have ever got out of your car After Japfest was over I drove down to see family & stay over the Saturday night & drive home Sunday afternoon I filled up & just about topped the tank Sunday morning before going to see my parents, sister & brother in law again in the morning before driving home Heres the receipt I did a total of 9 miles before the drive home & the total for the run was 214 but when I got home I had to top the tank again as the gauge was just below 3/4 full & wanted to know the actual economy I actually slightly over filled the tank as there was a little running out at the bottom, had also forgotten to change the time for BST so the time stamp was an hour out The total fuel used was 23.64 litres for the 214 trip This works out at 5.2070 gallons (litres divided by 4.54 to convert to gallons) [edited to 4.54 not 2.54 doh] So the MPG worked out at 41.098 which is a lot higher than I ever managed before In theory I would be able to drive a staggering 542.5 miles on a full tank Also interesting that Shell fuel is 3p a litre more expensive in the south than in Yorkshire Whats the best you have managed?

dublet Posted May 13, 2013 Report Share Posted May 13, 2013 That's actually 5.20007 UK gallon, so 41.148mpg. ST202s are supposed to be capable of 43mpg but I never got much more than 35mpg. Best not ask about the Faff. :rolleyes: Link to comment Share on other sites More sharing options...
cooperman Posted May 13, 2013 Report Share Posted May 13, 2013 on a trip to pick up a land rover disco in mid wales i got 39.8mpg (or 38.9 was a while ago now) in the gen5. mostly motorway with a bit of tiny welsh tracks to find this car and back again. worst i got was at santa pod and i think it was some thing like £20 for 4 runs so about 2 gallons to the mile. but that is a bit of waiting in line and pushing 90mph in 3rd.

Askari Posted May 13, 2013 Report Share Posted May 13, 2013 Are you sure you've got the maths right there? You said 23.64 litres for 214 miles? Divide by 2.54 would give 9.3 gallons surely, not 5.2 gallons. Therefore around 23 mpg?? Not sure I've done the maths right either. I've probably miscalculated it myself and I'm at work so I haven't got time to work it through again. Sorry. Anyway, I took my gen 5 round North Wales over the weekend - and did 300 miles almost exactly. I put a fraction under 38 litres of fuel in before starting - and the fuel indicator was almost exactly back to where it started when we got home. So that's 300 miles divided by 38 litres equals about 20-21 miles to the gallon! The database says that typical consumption on a gen 5 is 28.5 mpg - but I guess you've got to drive more carefully than I was doing to get that. Expensive stuff.

dublet Posted May 13, 2013 Report Share Posted May 13, 2013 Dividing by 2.54 is to convert centimetres to inches. However Phil's basic calculations are mostly correct, apart from what I corrected him on. 38 litres is 8.35883 gallon. Over 300 miles that's 38.89mpg.

ams Posted May 13, 2013 Report Share Posted May 13, 2013 1 gallon = 4.54litres - think sums are correct but just a typo Link to comment Share on other sites More sharing options...
dublet Posted May 13, 2013 Report Share Posted May 13, 2013 1 litre is 0.219969 imperial gallon. Or vice versa, 4.54609 litres in an imperial gallon. Link to comment Share on other sites More sharing options...

Yep, you're right - I got all my calculations wrong - including my own mpg which as you say works out at about 38mpg. Apologies. Link to comment Share on other sites More sharing options...

vvtirob Posted May 13, 2013 Report Share Posted May 13, 2013 Celica 7 Fuel Tank Capacity: 55Ltr (12.10g) 1 Imperial Gallon = 4.54 Litres 136.9 = 1 Litre of V Power Nitro I personally fill up about 25 quid a week, which is about 18.24 litres in my 140. 22 mile round trip, 2.8 miles of 40mph carriageway usually riddled with traffic, the rest is motorway. 18.24 / 4.54 = 4.017 Gallons 22 * 5 = 110 miles 110 / 4.017 = 27.38mpg Baring in mind, 8 miles of this is literally crawling traffic. My BEST run was on the way over to Brum, averaged about 51.8mpg down the motorway and A38. I think that's all right... if my calculation is off, then my results are totally wrong.

NJay Posted May 13, 2013 Report Share Posted May 13, 2013 (edited) 32.4mpg is my best so far ...... with the supercharger fitted I just about got 31 driving to and from work 25 mile round trip when mine WASN'T supercharged. With it it dropped to 23 lol. On the journeys to meets (typically 90miles each way) I would get 36 and 28 before and after charging. The auris that I have as my daily driver does at least 37 for the the same daily commute. However I only got 34mpg going to/from japfest as there was no convoy this time Edited May 13, 2013 by NJay Link to comment Share on other sites More sharing options...
