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.

My new Yukon has grade braking and it works too well when empty. I didn't buy it to tow but may tow an enclosed trlr someday and I will let you know.
