At walmart, pennzoil platinum and PP HM are the same price. Also, valvoline synpower and synpower with maxlife are the same price. Valvoline says that you can use their synthetic maxlife oil in a new engine, and it would help prevent high mileage problems before they occur. They also say that their synpower with maxlife is their top-tier oil, with a stronger additive package than regular synpower. It has more detergents/dispersants/antioxidants, more anti-wear/friction modifiers, and seal conditioners. It even contains an ashless anti-wear/friction modifier which is most likely an ester.
Is there any reason not to use PP HM or synpower maxlife in a new engine? For the same price, wouldn't they be an upgrade over their regular synthetic oils?
