2013 Ford F250, 6.7 Diesel, Suggestions to improve mileage.

Empty and you're only getting 11.8 MPG????????


On an F 250??????

Good grief, I previously owned a 2011 F 350 crew cab dually with the 6.7L diesel and I got a LOT better than that empty. Driving slow at night (58 MPH) I got 20 miles to the gallon once, and could usually average a good 16-17 miles per gallon.

Somethings wrong with your truck. I'm not mechanical enough to venture a guess, but something is really wrong to get that poor a mileage.

Or, you've got diesel thieves. :B
