Too many variables to say. My Diesel cars didn't have choices on drive axle gears and just two transmission choices - auto or standard. Not the same for trucks.
Long story short, dont buy a 3/4 or 1 ton for MPG. You are KIDDING yourself. Buy it because you need it, which to me means you pull more then 10,000# weekly. I have both a 06 F-350 diesel and a 08 Nissan Titian. I pull a 9,700# load weekly 120 miles with the Titan and average 9.3 mpg because it does the job and when you look at the cost of ownership of a diesel truck (tires-filters-oil-batteries-breaks) its cheaper to run the gas Titan.

The new H.O Cummins putting down 800 lb.ft gets less mpg's than the Ford 6.7l but that's what happens when you turn up the fuel on an older design to stay in the power wars. The normal Cummins making 650 lb.ft. seems to return much better fuel mileage.bdog said:I have a duramax in the past and it was ok but I really prefer dodge or ford more. I know the older cummins were legendary for mpg but it seems the new fords 6.7 is reporting better mpg than the new cummins?
