my 08 Duramax got 16-17 mpg when i got it. after i pulled all the emission crap off and added a "little" tuning,
and a 4'' exhaust, she consistently got 20 if you didnt drive like a bat. stay away from the 6.7 Cummins. they're a piece
the 6.7 has been just as good as any of the other brands new engines. they all stumbled a bit to begin with. id prefer it over any but i just dont like the dodge truck really
