My mileage on the hwy. hovers between 28-32mpg. 28 if I have to get out of cruise a lot, and Ive managed 32 on quite a few occasions with the cruise pegged at 80mph. Usually stays somewhere in between. I have no idea what kind of mileage I was getting before the mods.
Gotta love cross country driving when you can set the cruise and forget about it until you have to stop for gas!
