From 17-19 two wheel drive on the highway. 12-14 four-wheel drive in town, not towing. towing a hefty load and some hills, 8-12. Really depends on what you are doing. These also vary a little depending on if you have a power stroke (turbo) and if you run fuel additives, and if you let it idle during a hockey game, because it is -30 outside.

Hope that helps.
