    Hello all,
    I just got a 1995 Ford F250 with the 351W and auto e40d trans. The truck has 95000 miles and well i know it is not going to sip gas, i would like to get a little better mileage than I am now. Just from driving it around town i calculated 6.8MPG with the truck empty:eek:. For me that is pretty rough and I really think it should be better. The truck has an MSD distributor, flowtech headers, and a K&N filter in the airbox from the previous owner.

    Although the plugs and wires looked okay to me but I am going to pull them and put in new ones as part of a tune up and see if that helps, I am also going to seafoam the engine before I put in new plugs to try to clean it out a littl bit and hopefully that will help. Is there anything else I can/should do to try to get some mileage back?!

    5.8W good luck, is that 6.8 around town or highway because you might get 10 mpg's on the highway.

    Yeah when I worked as a Ford Tech that was a big concern for Ford truck owners.

    Andy that 6.8 mpg is gonna look good once you start plowing. I have a 96 F-250 with a Snoway V on the front, and a rear plow on the back. I think 4 mpg is about what I am going to get with it once it finally snows here.

    Well good news... kinda.... my mileage is going to go up very soon... i was doing some work tonight and noticed I smelled gas... low and behold I look underneith and the front tank is leaking :( haha. the old owner replaced the back tank though so I am going to use that one for now and probably swap out the front one in the spring... Having all my gas might help my fuel economy :)

    I never got better the 10 mpg highway driving to work in Cleveland and back. A 60 mile round trip. But it was a 3 speed C-6 transmission no over drive. No weight on the truck. It was in total tune and everything lubed and straight. I just drove, no aggressive / angry / high speed driving.
