How many miles since the O2 sensor was replaced? A bad sensor will cause the Motronic to run a richer fuel mix. A couple of years ago I changed the O2 sensor and it improved mileage by about 3 or 4 mpg.

'90 735iL 155k mi: I am not getting the mileage that I think I should be getting - 18 mpg vs. what most people say should be at least 21 mpg. I am beginning to think that the tranny may not be shifting properly. I will be changing the tranny screen soon.

My question is: what should the RPMs be in the top gear riding steady on a level road? I see about 2100 RPM at 60 MPH and somewhere around 3000 RPM at 80 MPH.
