I got better mileage than that in the Mustang!
Eh, to be honest I'm surprised it's that good. It's high strung, crazy short geared engine / drivetrain. 6th gear at 80 is @ 4500 RPM. On the up-side, when you hit the throttle going up a hill on the interstate in top gear, it will actually do something, as opposed to the protege which would usually just stay the same speed lol
