Car runs 5w-20, thought I'd run 0w20 now since there's no point otherwise for the 5w. Last oil change had the Pennzoil high-mileage blend, so what should I add to the oil to help maintain that high-mileage formula? Would a bottle of 5w-20 high-mileage whatever be suffice?
The Havoline and Magnatec are the exact same price for the 5qt jugs, and am not sure which to go with.
