I recently purchased a 2006 F-250, Supercrew, with the 5.4 gas engine. I have been checking my fuel mileage periodically, and I am averaging about 12-13 mpg. Can you recommend anything to help with the mpg (Superchip, exhaust, etc.)

 

Drive like there are eggs under the go-pedal. Thats about all you can do.

Don't think that you bought the wrong truck though. The 6.4L diesel is getting the same if not less than what you have.

 

Thats all I get too. once I got 16 on a trip. I am looking for help how to change the back emergency brakes, any help would be greatly appreciated. mike

 

i have a 04/f250/5.4 /a trans i get about 12 to13 around town and 14to 16 on the highway i have a superchip i have changed the y pipe were it goes form 2 1/4 down to 1 1/2 back to 2 1/4 i have opened up the intake tube from 2" to 4" and i know there is still 1 or2 things i can do and am working on doing p.s the 5.4 and the v10 / the superchip works best on tow safe

 

I have a 1997 F250 HD with a 7.3 PS and 410 rear end and I get 16mpg around town and 20 on the highway. Man and I thought my mpg sucked. I won't say a thing ever again.

 

Is it true that if you change the gearing from 4:10 to a 3:73 the tow rating goes down a little but your MPG goes up a little. I may have it bassackward but just a thought.
