There is no better oil. Each oil has more or less benefits depending on your situation. Like anything you get what you pay for, cheaper oils have less costly additives that keep your engine clean and wear to a minimum.
valvoline is the best oil you can get. its alittle exspensive but it keeps your engine in good strong running condition.
