So after reading all the terrible mileage questions and answers about the 6.2 I did a trip yesterday from northern NV to Scottsdale AZ and I ended up with a mileage or 20.9 after 721.4 miles at a average speed of 70 on the computer, a lot of the drive was in the low to mid 80 mph. Is this normal with a 6.2 ? Or did I just get lucky. I am running premium fuel as recommended. Stock wheels and tires. My brother gets this mileage in his 5.3 RST but I didn’t think the 6.2 would.
This can’t be normal ?

Was the whole drive downhill with a tailwind? Only partially joking, but congrats on the solid MPG.

For sure some of it was with a tailwind but mostly a nasty crosswind in Northern NV. Technically it is downhill cause I’m going south right ? All jokes aside it is about a 4,000 foot difference but there is a ton of ups and downs, I guess I will see what it looks like on the way home I will reset the computer and try again.

This was last month while I was in Florida. 6.2...
On my Tundra, that display always claims 4-5 mpg more than I actually get. On my '24 GMC 6.6L, that display is exactly right every time. I do the calculation every time I fill up.

My 24 GMC 6.6L gas motor gets absolutely horrible gas mileage..like 10 to 12.…I’m not complaining to much. I just thought it would be a little better, but for 76.5K sticker I feel sorry for the guy who didn’t put down at least half because you will go thru some gas in this thing.
I'm hitting 12-13 combined with my 6.6 gas HD but I typically hit 18-19s and touched 20 a few times if all highway.

Had a 6.2 in a Yukon, it did in the mid 20’s all the time. My 2022 AT4x, not as good. Gonna say high teens to low 20’s- depending. Quit lookin, figure did not buy for MPG. She holds solid as a rock- F to E Every tank

This is my first N/A gas vehicle in a very long time. Anything is Better than my hellcat and TRX. Best I ever got was 9. I welcome more than 200 miles per tank at this point lol.Had a 6.2 in a Yukon, it did in the mid 20’s all the time. My 2022 AT4x, not as good. Gonna say high teens to low 20’s- depending.

My AT4 is on order and I'm new to this scene. Not related to initial post but is the dash customizable? I never understood the tach on the right.
