I have a 2023 Yukon Denali with the 6.2. I'm about 400 miles in and am getting 12MPG.. about 1/2 my miles are at around 50 MPH, the others are surface streets. what are others experiencing?
Mines a 2022 and I get right at 22.5 mpg. Expressway averaging 70 to 75 mph. Both ways on trips But just running around town it’s about 16 mpg. I do drive like a granny when trying to get good mileage which is hard with the 6.2 and all the trans shifting.
