Anyone running Rotella T6 full synthetic in there l5p or is the general consensus that these motors like Mobil delvac? And follow up question is anyone happy with conventional over synthetic or vis versa for any specific reason.

Duramax's are super easy on oil, any CK-4 rated oil will do. Lots run T6 with no issues, lots don't and no issues.
