X-pack-Glyn Posted July 20, 2008 Report Posted July 20, 2008 i need some MPG figuires sorting for me please... no, im not tight i just wana make sure im not using more than i should be. Twin 40s with 30mm chokes, FR32 on a 2 litre, 4 speed, 3.77 and 185 60 13 tyres. 68 miles, (duals and motorway) at 70-ish. 25 quid of fuel used, surely thats not right...is it?
pauln Posted July 20, 2008 Report Posted July 20, 2008 Right take the money spent and divide it by the cost per litre. (£25 div £1.18=21.18 litres). Multiply your 21l x 1.76 to get pints (37.28 pints) and divide by 8 to get gallons (4.66 gall). Take your 68miles and divide by the amount of fuel to get mpg (68 div by 4.66 = oh shit 14.5mpg).You can take your fuel from litres to gall by multiplying by .22 (21.18l X .22=4.65). Is your milometer accurate and you did go from brimmed to brimmed when filling.

That'll only lean it off on the idle circuit, maybe you need to look at the mains too.
