Coincidentally, I just put 300 miles on a brand spankin' new F-350 today. Averaged 13.1 MPG pulling a loaded trailer. The truck it replaced was an '09 F-350 with a 6.4 and the afterburner exhaust; on the same run it would get 7-8 MPG.
You are comparing it to a 6.4 though! Haha. Worst diesel ever built!
I'm a duramax fan. The new d-max is pretty awesome. I guess i would deal with it til the warranty is up then delete all the crap.
