Thats what I passed. I don't believe 25mpg under any real world driving for a second. Maybe on a fluke, but not even at 55mph steady should it be able to get 25mpg. Seriously, my pickup without all that extra weight and stuff hanging out in the wind got a max of 28 at 55mph, I usually get about 24 at 75ish.

If a car has to be driven at full throttle it will/should run rich, unless its been modified to do otherwise, and it will burn more fuel than a larger engine that is producing the same power at a lower throttle. When moving several years ago my father inlaw helped us move with his full sized truck, under similar loads my mileage droped from 26 at the time to 17, his droped from 20 to 18. He actually burned less gas because I was straining my engine too much, and his was just chugging along just fine. We even dropped down to 60mph for most of the trip.
