I average 300 miles and the best i have done is 350 miles but that was motorway driving.

Other day when i got fuel, the clock was on 262 and i put in 20 litres in a 45 litre tank. I worked out the mpg and it was 46 i think. Again motorway driving.

My moded G running 65mm pulley and chip etc averages from 170 to 220 miles from a tank of unleaded. If I use super unleaded I get about 20 to 25 miles more.
My stock G averages 360 to 380 miles which is nice.

It depends what spec your running and what roads you use like town or motorway?

i normally stick 15 quids worth of super (either v power or momentum) and get between 70-110 miles depending on how i drive

fuel consumption is always worse in the winter.

15 quids worth in the 16v afh mk2 got me 120-140 miles,a and i drove that like a bastard everywhere

not being funny but if your answer is coming to 46mpg I think you are working it out wrong. 

35mpg is reasonable on a good run, 40mpg is possible if you drive like a granny.  46 is just a bit too good though, especially in the cold weather, maybe if you are working out mpg while coasting down a large hill?

I definitely get better mpg on motorway runs in mine since the turbo conversion though.

I worked that out myself and i was proved wrong by this website. This website actually came to 59.55 to the gallon. Have a look for your self.

When I did my best at 350 miles and 40 litres of fuel it came up at 39 Mpg

Best I've ever had out of a tank is 430 but that was running a charger in very gently on one long run. I normally get about 350 with mixed driving but that has dropped in the cold weather.

Yes, that is true... But you reconsider every time you have to refuel! :D

That's only 43mpg or so Dan! I've got 41mpg out of my turbo taking it steady(ish) on the motorway.

i once did 436 to a tank but that ran dry and was stranded on the motorway - this was basically 60 mph for teh whole tank though off boost

it's actually a smidge under 48mpg! (assuming 9 gallon tank)

You must get more than 9 gallon in, I worked it out to be about 43mpg as I recall. Dan if it makes sense or not, it happened.

i get what you are saying but there are variables that could be wrong(wheels, tyres, gearbox error), and user error too


i personally can not see it, but if you say it happened it must have lol

The tanks are 45 litres though I thought, so more like 9.9 imperial gallons.
