X3 3.0D MSport Auto Fuel Economy
Ok been onto BMW regarding fuel economy on my car as the absolute best i can get on a good run with sensible driving is 28.4 mpg and it has been down as bad as 21mpg. So what are you achieving on your 3.0 diesel auto box. I also have 19" rims if this affects economy at all. So let me know what size rims and mpg
Cheers
