Had the truck for a couple of weeks now and I'm getting 16.8 mpg. The F150 (6.2L V8) got around 17.8 mpg given the same driving conditions. As the Rebel is not yet broken in, I think that's pretty good all things considered. I expect there will be an improvement after break in? Realizing this is a truck and not a Prius, I don't expect to get phenomenal gas mileage!!
