Gas milage on 2005 F250 Diesel

[61cadman]

I'm new to diesel last year. I cannot get more than 285miles out I a full tank. I get like 12 miles per gallon. It has a leveling kit with 35" tires. Is this normal? Everything else is stock.
Thanks for any advise.

My 2007 CC, 4in lift, 35s'' gets about 13-14 MPG.

Stop putting gas in it. Just kidding

What gearings in the rear end. Should be better mileage than that

[61cadman]

Not to sure. It's all stock. I bought it from the original owner that never did any modifications. How could I check to see?

3.73 gears?

Would a dirty fuel filter give me bad gas milage?

It's not all stock if it has a levelling kit and 35's. However, 12mpg is probably 2-3 mpg less than what I'd expect. Really depends on how you drive (city vs highway, how hard you accelerate, ....)

Are you hand calculating or going off the overhead monitor?

[SuperCrutyPS]

Dirty filters (Fuel, Air) can contribute to lower mileage. Another common thing to check would be to check air pressure in tires, especially now that the weather is turning cooler. But probably the biggest contributor, as stated above, is how you drive. The easier on the skinny pedal you are the better the mileage you may get.

Same here averaging 11 with sig mods plus power service fuel additive in every tank.

what are you complaining about. i hand calculated and ended up getting 9.
