I just did the 3rd oil change on my 2023 GMC Sierra 1500 with the 2.7 "TurboMax" engine. Absolutely no problems with the truck but I for some reason decided to use Valvoline Restore & Protect 5w30.
After the factory fill was out the 1st oil change was a dealer freebee and the 2nd one was Quaker State Full Synthetic that I had previously selected to run also in my 2024 Ford Transit 250.
For the first 9,000 miles of the trucks life on generic dexos and the QS, the truck met the advertised 18/20/19 mpg on the Maroney sticker, but in the first few hundred miles running the Valvoline Restore and Protect the mpg has jumped on average 2mpg.
I have never ever experienced a mpg jump just due to oil brand change so this is weird.
My plan of action is to run 3,000 miles and then do a change to Valvoline Advanced FS to see if the mileage drops back to what it was doing on the generic oil. Also I realize that the Restore and Protect is not dexos certified but i'm not worried about it and honestly this was just sticking my toe in the water to try the oil. Was probably just going to go back to Valvoline Advanced or Pennzoil Platinum after the experiment anyway.
