Has anybody here ever used Schaeffer oil? I'm changing my oil in a couple of weeks and i'm giving them a try. Everything I've read and heard they make some really good oil and been around for a long time since 1839. I've used Royal Purple for years in my other vehicles, just last year i've tried Amsoil which i'm thoroughly impressed with. Now i want to see how Schaeffer Oil is.

Schaeffer's does make some good oil but since your car is under warranty I'd only use oil that's recommend by GM. You can't go wrong with any oil meeting GM specs from a name brand.
