I'm totally onboard with the calculations it's just the tank size that's confusing me. £21 means I'm only putting about 15 litres of fuel in (3.3 gallons). Just seems very odd that the light on a 20 litre tank comes on when the needle is right at the bottom of the guage, but I technically have 1/4 of a tank left.
re MPG, I get about 180 (just under) miles for my £21 before the light comes on again, that's 54 mpg and that's with some fast acceleration, 80/90 on the 10 miles of dual carriageway each day.
I've recently done a little experiment on the last fill up. I didn't go above 5k revs. No over takes, 60mph on the dual carriageway and the light came on at 207 miles, that's almost 30 miles more per 15 litres! WOW, didn't think it would be that different.

Money doesn't buy happiness, but it buys beer, and that helps!
