Hmmm.... even though I don't have a recent model GM product, use DEXOS1 licensed 5W30 syn-blend in my Subaru because 1. Jug of it is cheap at Walmart and 2. DEXOS licensing tells me it's high quality . . . even though it's Quaker State which some people bash (even though QS is part of SOPUS since whenever).
