I drive normal with some spirited driving. In town, I get between 12.5 to 15.5. I haven't had a chance to go on a road trip yet. I will next week. Best I've gotten with a combination of town and some interstate was 18. Maybe my 3.73 gearing hurts some, but I wouldn't think that bad. I hear a lot of folks on here saying they get 18 or 19 in town. Hmmm.
