I got 38.9mpg for my 30 min drive to work this morning

that was through a mix of town driving and 50mph lanes, and I was trying to get the best mpg.
I used to have a passat 1.8T - it had done 135,000 miles and the best I could do on a drive to work was 32mpg, I think the golfs lighter weight and an
engine that has only done 29,000 miles makes a fair bit of difference, the golf is chipped too!
I know most chat is about the quickest and fastest cars but it's fun (and hard!) to try driving to get the best mpg too!
Whats your best?
