Mileage
I just replaced my 2001 7.3 powerstroke with a new 2016 6.7 powerstroke 4X4 I know the 6.7 won't get the mileage that my old truck got but once it's broke in what kind of mileage are you 6.7 owners ...

My friend bought a 2016 F350 CCLB and got 21 mpg on the highway from Maryland to Florida earlier this fall. At highway speeds these new diesels are impressive with power and economy.
