HI highflier, Your a lucky guy, I bought my 2008 6.4PSD SC LB 4X2 last week, only have 241 miles, I check the computer for MPG and it said 9.2 MPG, WTF !!! My 1999 7.3 would give me 15.5 to 19.0 MPG with A/C on and me driving it like I stole it, and in BAD TRAFFIC, MOTHER FLECTHER, I should have bought the dodge with a cummins, The FORD tech told me as I break it in the MPG will get better, he said like 12.0 MPG. If thats the case, I mite forget to remove the keys from it, when I'm in the PROJECTS !!!

HI atk, No not yet, only use the on-board computer, BUT I filled the tank all the way, and I'm going to hand calculate it !!!!

The on-board computer dont work right all the time and there off even more with a tunner. Mine said I'm getting 15.6 mpg, but if I do it by hand I'm getting like 18 mpg.

HI GUYS, I hand calculated my MPG on the 2008 F250, and got 14.029 MPG, then I check the on-board computer, and it said 15.3 MPG. I think FORD'S on-board computer is lying to me ????? :dunno
