However it only averages the last 50 miles. So just drive.
If that's true (only last 50 miles averaged) then mine's broken because it hasn't budged even a tenth of a mpg since I got the coach 3 years ago. That includes driving with/without a toad and over varied terrain. I always figured the average mpg was for the life of the motor -- hence, once you got 20-30K miles on the rig, the average was unlikely to move, unless you had a problem with the engine.
