Tank #1: 25.7 MPG
Tank #2: 25.2 MPG
Note, both of these include about 20% of city driving. I drive about 7-8 MPH over the speed limit. So around 78 MPH on the interstate drive. Overall, the truck did very well and it's one of the smoothest engine combos I've ever driven. This is my 4th Duramax altogether.
06 LBZ
11 LMM
17 Colorado 2.8L Duramax
21 LM2 Duramax
I'm just now including this as I just purchased the truck on 5/28. I started this site back when they first announced and drove my friends off and on for a week while I was deciding, then life happened (Covid, etc).
Still waiting on my floor mats, but hope to get those by the end of the week since I'm back from vacation.
