My 52 plate Cooper seems to be getting rubbish MPG.
According to the computer, I only got a average of 34.8 mpg on a recent m'way run from Glasgow to Blackpool and back.
I was sitting at a average of 80mph, tyres were all inflated to 31psi and it had a INSP 2 service only 4k ago, the car was 4 up and the air con was on.
I did the exact same trip last year in my dads A8 3.7 and it got 28mpg, any ideas?
