Also does anyone know the gas tank size for the 2024 AT4? Thanks to everyone for the help. I'm new here.

27 gallons I believe unless they changed it

gm recommends premium for the 6.2. you can run lower grades but wont get the advertised power from the engine.

Actually they did change it to 24 gallons.

i don’t have the carbon pro series, but I do have the 6.2L. The dealership said it was recommended that I do mid grade (89 or higher); the weird things is after I fill up, I’ve seen “380 till empty” all the way up to “430 till empty” with mid grade. Can’t figure that out. Any others?

The distance to empty is calculated by the current mpg’s the computer is showing. In town driving will be lower mpg thus lower DTE. Highway driving will be higher mpg thus a higher DTE will show at fill up.

Well that made too much sense for me to figure out. Lol. And here I thought shell gas wasn’t as fancy as BP this whole time.
