Yeah, been my experience as well. I get much better mileage on parkways and stuff with 45mph speed limits than I do on the interstate at 75mph. Also, I can't speak for anyone else but the MPG computer tends to be further off when cruising. Like if I do an 80mph 200 mile trip, it'll say 39, but once the math is done it's actually 34. Cruising around town, if the computer says 34, I actually get 34.
My Focus actually got slightly better mileage cruising at 80mph. (But significantly worse mileage at every other speed)
