carman850, that's good gas mileage, our mpg is about the same, mine went down 16 to 17 mpg, since my repairs I hope it goes back up. Has your mileage gone down with mileage and how bad is your mpg for winter driving in all that snow?
Concerning Sunoco gas, my old BMW friends would never use Sunoco gas, it had something to do with the blend and it would in someway harm the engine?? well that thought must have been totally wrong, with 220K KM on your 400E.
enjoy your drive, timreid
