2.oltr d auto ltz have done 4375 miles so far MPG on a run is about 38 to the gallon. Around town i get around 28 miles per gallon. not bad for a big car. But son gets more to the gallon as he says don't put your foot down so hard. Can't help it just to see how many BMW drivers i can upset. HEHE The car not that slow is it?Also i found the engine is much quiter on shell disel compaired to others and seems much happier. Still verey happy with the car.
