My 2022 AT4 6.2L I noticed it consuming oil at less than 3500miles on the vehicle when it started to ping me that my oil was low. WTH??? I bought the truck brand new with 50miles on it. When I checked the dipstick, it was completely dry and took two full quarts of dexos™1 0W-20 Full Synthetic Motor Oil to bring it to a full level. After that experience I have been taking it into the GMC dealership every 700-1k miles to have an oil consumption test done on it and it is always down at or over a quart of oil which they conveniently top it off. They have been documenting the oil consumption's since I have purchase this truck back in Jan 29, 2022. I am now at over 17k miles and coming up on my 3yr anniversary of the truck purchase this coming January 29, 2025. I will be discussing "what is next?" with that dealership and my truck issues after the warranty falls off and that this needs to be fixed as I am not going to be continuing to carry spare quarts of oil in my truck to use every 1500 miles so that it doesn't run low. It is ridicules that a brand new vehicle eats oil like this. My '06 5.3 Silverado never ate oil.
