Remember "weight" "tranny" and "altitude" have quite a bit to do with it too. Say for instance you're going through areas that are 1K ft higher on the average and don't have AC or anything on you may get the same mileage as you do at 1K ft lower and hammering it. Then the weight. Even 100lbs will make a difference. Doesn't seem like much but it adds up on a whole tank. Can you say, uh 260 miles per tank?!! I can. LOL!
