Ford F250 mpg and other info?

They come with a 5.4l engine or a v10... The 5.4 will get around 10-12mpg. That is a very small engine to be pushing such a large truck. I had the Expedition with the 5.4 and that got about 9 mpg in the city and around 12 on the highway... You could almost watch it move. I've installed the chips and programs to most of my vehicles and I have never noticed a difference in mpg.... The BEST item to increase MPG has to be a K&N filter....Good luck!
