What oil do you use? I'm hearing all sizes of GM motors having trouble with the 0w20 oils so they recommend going 5w30
Edit to add.. I've been a GM guy my whole life but don't think I'll ever go back.
It had to be Dexos 2, I can't remember what brand. 5w something. I don't buy 0w anything, just seems wrong.
Have a gas colorado now with 2.8 turbo. It has been flawless.
