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 ...

Mileage won't change due to break in, that's an old wives tale.
I would disagree with that statement...
In early 2000 I bought a VW jetta TDI for commuting.
Off the lot it would return about 35-37 mpg with 90% freeway driving.
I logged the mpg over the next 14 months and the mpg steadily increased until it reached 50.1 mpg average.. Mpg got better as the engine broke in, my driving habit ( speed and miles driven ) was consistent. Even more surprising was the mpg after 300,000 miles.. still averaging 45 to 48.. !!
So.. how do you explain the increase in mpg over time if not from
reduced frictional losses as the engine's surfaces "smooth out". ?
No kidding my 98 12V RAM's mileage kept improving up to 150K.
