I saw 28 a few times and even got the missus to take some pictures of the DIS on her mobile. I'll post them up once we've got them off her phone.
I use to struggle to get that with my old 2.8 v6! I wonder if its the tyres on mine that are causing me to get such a bad mpg?
Since I last filled up I have done about 150 miles and the range is saying 140 left so thats an improvement at least
