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.

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.

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.
 

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.
