  1. Just bought a used 2017 Denali with the 6.2 earlier this week and took it from Colorado Springs CO to Ogden UT and back and got 37.0 for 25 miles and 30.6 for 50 miles between Laramie WY and Fort Collins CO and 21.7 for the last 400 miles. This was on a cold and windy day doing 75 to 80 on I-80 and dealing with Denver weekend traffic. Granted the stretch from Laramie to Ft Collins I had the cruise set at 68 and it must be a lot more down hill than I thought but by no means is it flat there are some pulls on 285. I was pretty impressed, did a lot better than my 06 Chevy crew 4x4 with the 5.3 ever did on this same run. Hand figured mileage for the entire 1253 mile trip was 20.8
