quote:My thoughts exactly! I just got back from the trip and recorded my best ever on my 325i - 30MPG. I made 450 miles on a tank with on-board computer showing some 30 miles left, 150 miles were done in the city, the rest on a highway doing around 80MPH. The car is just reaching 16K miles and I run BMW synthetic, rather thick 30 weight. I expect even better mileage in a future and don't see how 20 weight could make a significant difference. One think that amazes me is how big is the difference between city and highway driving on my bimmer. OBC shows only 18MPG during city and occasional backroad driving. I bet it would probably go down to 12MPG if I took the car to the track.
