Depends on how big of a hurry I am in 
!
I usually get around 15-17 Hwy @65mph and 13-15 in town.
But on the other hand if I drive like an old grandpa, I can squeeze as much as 20 mpg out of the 'Crew.

Before putting on my 6" lift and 35" tires, I was getting about 14 mpg in town and 19.5 mpg on the highway with my 2003 F150 5.4L Supercrew. I have the 3.73 rear end gearing.
Now with the lift/tires I get about 14 on the highway and about 11 around town.

Thanks for the responses.
I was just seeing what they get. I have never tried to see what the mileage was at normal speeds. I get around 10 mpg with mine, doesn't matter where - city or highway.

I have a 98 F150 5.4L 4X4 with a 3:55 rear end. The truck has a K&N air filter and I normally use partial synthetic oil. I have kept a mileage log on the truck since the first tank of gas. The present mileage is 68000. It is difficult to generalize but in round numbers ....here goes. City 13.5 to 14, highway 15 to 18 (I think wind speed and direction matters), highway towing a 7,500 lb boat/trailer 8, and highway towing a car hauler trailer and car (5500 lb total) about 12. These trips are back and forth from Michigan to south Florida and therefore pure highway.
Hope this helps.
I have an exhaust manifold leak caused by a broken stud that I intend to use as an excuse to upgrade my exhaust with a header and hi flow muffler and hopefully before November purchase a 1715 superchips tuner. I will do these upgrades one at a time and should be able to establish verifiable mileage changes.
