My other car is a MINI!!!!
i was going to say..... 248 miles to 31 litres sounds damn good!
working it out its actually 36.4mpg! which is actually awesome. at that mpg i highly doubt the computer is bringing the light on early due to driving style!
as far as miles to a full tank goes, i can get around 360 if i try, in theory i should be able to get 400 to a tank, but i always get bored after 200 miles or so and the economy drops off a little as i get bored.
last week on a trip up north i got 39.8mpg cruising from portsmouth up to northampton,
then 34 on the way back because i was in a hurry :D
that said, i thought the A3 had a 55 litre tank?
