I know I never built my car to be economical, but I just went out to fill the car up as I have an early start tomorrow.

I had only done 48 miles since my last fill up and it cost me £10 to fill her back up again, so it gave me a chance to work out the MPG - I have worked it out at approx 25mpg does that sound about right..................not really too fussed as I did enjoy those 48 miles

that is good, the best i got on a sensible long run, 500miles was 24.8mpg

so 25mpg sounds good it that is proper driving.lol

stuart

About right! I get about that when blatting

Sounds about right - not very efficient those bike engines

That's OK then, it was driving round the local 'B' roads so bits of 'pootling' too bits of 'making progress'

I got 30 MPG out of my carbed R1 MNR. I drove it to the red line at full throttle in every gear when traffic allowed too so I wasn't being gentle with it. (when I was running it in I got closer to 40). It wasn't a particularly light weight BEC either. On the track I would get more like 20 MPG.

im getting 37mpg if im going steady and 25ish when playing with locor1, kev and ed

I'd be very concerned about ca. 25 mpg, very.

You clearly have a serious problem, but before you panic, I'd advise checking a few simple things: Are the revs being kept above 10K at all times?; Does the throttle open all the way?; Are the rear tyres smoking on pull-away?
If all is positive in the above, ensure the injection rail is running at ca. 3 Bar.
If all else fails, an overbore, race cams or forced induction might get the mpg down a bit. Good luck, hope you sort it.

You wont get that tomorrow! Last 2 south coast runs I've nearly run out! Lets just say I spent a significant amount of the last run to Goodwood with the RPM light on

Prefer not to think about it normally lets just say it likes a drink when it gets some stick
Worked it for the first time on our trip to Belgium this year and it averaged 33mpg on the 800+ mile round trip!

Crikey! Can't believe that some folk are concerned about the MPG figures quoted on this thread! Bloody good if you ask me!

I was a sports-biker for years and would have been delighted to get those figures when blatting!

A long long time ago, so long ago I was living at home still, and staying in when brother, sister, mum and dad were all on individual nights out and I was skint. My Dad felt sorry for me, and offered a tenner to stick in my bike so that I could take it for a spin - I explained that a tenner would get me to my G|F's, but not home if I was driving "properly" (). Her house was 34 miles away - Jeez, I used to ride that bike hard! Oh to be fearless and 21 again!!!

At a TD at Anglesey last year, I took a FuryBlade, and couldn't fix a fellow Locosters, Blade Striker that was having problems, and because I couldn't fix it, I felt quite sorry and lent him the Fury for a couple of sessions!
Gezza from here then in turn lent me his MK (Busa) for a quick spin, took it out, did a few laps, changed some suspension settings and then took it out in earnest. The MPG figures for the day were:
Gezza's Mate - 5.1 MPG
Gezza - 3.8 MPG
Me - 3.1 MPG


25MPG's just is not trying hard enough!!!

i can do more than 80 miles of thrashing on a 25L tank.

I can just about road test the engine driving to the local petrol station (12 miles away) with the 10 litre tank. Westfield GSXR1000 (Mistral race unit).

MPG isn't the problem, it's usually MPE.

If I need MPG and boredom I simply get on my Tenere (XT660Z),
