I get about 320 miles per tank when taking it down to about 20 miles remaining if using momentum and about 300 miles with anything else. A quick solo shopping trip in the R last night saw some very low mpg as I was keen to feel the power of the R again after being in the A1.
That's the trouble, I'm a bit too keen to feel the power of the R anytime, even on the school run!
The long term average mpg, is better than I got with my Mk6 at the same stage. If I can get 280mpg in time, from a tank, I'll be happy, anything over will be a bonus.
