GMs new 6.2 di seems to get great mpg
I have read a lot of owners reporting 16-18 average and 20-21 highway out of a 6.2. Any here have a new one?? MPG numbers please.

The problem with engine braking on the 6.2L is similar to thee Ecoboost. They have enough power that the engine doesn't need to exceed 3000rpm very often and there is not enough compression braking at that low of engine speed. Spin either one up to 5000rpm and it will help slow down. Not as much as a diesel with exhaust brake, though.
