GM Duramax 3.0 oil consumption

Guys, manufacturers and engineers know best. If GM says it’s normal than I’m sure a hoard of engineers carefully reviews and studied the problem and deemed it OK. No manufacturer would make a statement that is not backed by cold, hard facts. Their reputation is at stake here.

Just keep giving them $70-$100k for these trucks and be glad they sold you one. 😉
lol, ever heard of a little company called VW that was run by a Nazi in the 21st century?
