1,550 mile round trip high speed mileage!
 

had to drop off my friend off in Alabama from Michigan i drove an avg of 80 mph so 75-95 mph and was surprised with getting 31 mpg! for a 2000 cavalier 3 speed auto on a 211,600 mile car.... i thought for sure i would get like 25 mpg because of 3 speed auto... did snag a few backed up traffic i am sure it killed my mileage for a little bit.. so i thought it was pretty good mileage for the high speed...

Congrats, I guess that much of all highway helps, mines a 4 speed and I do like 65-70 on the highway and average 30-31. So doig an average of 80 and getting that is better than I'd expect.

yeah i was surprised with a good mileage at high speeds lot of it was the wolf pack at one time i was at 90 mph for a good hr or so and like 10 of us in the left lane was just whizzing by!..the whole trip was just sunny out

just courious, what are the rpms at 70

don't have tachometer on my car.... a 3 speed auto they are supposed to run around 3000 rpm
