What happened to 3k miles before changing oil? Is that old school now?
Why at 2200 miles? Was it run hard, dirty, or you just wanting something to do to it?
You actually want the thinnest possible (in the sae 20 range) for low shear (pouring) viscosity, and the most important viscosity for wear is the high-shear high-temp (HTHS) figure, which has a good value in the Valvoline.I've always felt like Valvoline was a bit thinner out of the bottle than other oils.
