Thats a little lower then what we are getting, nothing special,, have the same year as yours, we are getting that 14mpg with a combination short runs and some highway, all highway getting around 18 out of it on cruise. Newer 5.3L have the multi displacement and are supposed to get better. We have 3.42 gears, wondering if yours has the 3.73's in it.
