Pennzoil Platinum High Mileage SAE 10W-30 is a full synthetic motor oil that is uniquely engineered from our revolutionary PurePlus gas-to-liquid technology which is a patented process that converts pure natural gas into a high quality, full synthetic base oil. Because it is made from natural gas, the base oil is 99.5% pure, contains fewer impurities than base oils made from crude oil, and when combined with our advanced additive technology, creates one of the best formulations in our Pennzoil high mileage portfolio. As your car ages, leaks may develop and cause higher oil consumption and burn off, potentially causing your engine to need frequent top-offs. Pennzoil Platinum High Mileage motor oil is enhanced with an excellent combination of special conditioning seal agents and additives to help stop leaks from seals and reduce the oil consumption that is typical of older and worn engines. Our full synthetic high mileage motor oil also protects engines for loss of horsepower, offers excellent performance in extreme temperatures, and provides unsurpassed wear protection, and protection against abnormal combustion phenomenon like low-speed pre-ignition observed in modern turbocharged gasoline direct injection (TGDI) engines. Pennzoil Platinum High Mileage SAE 10W-30 is engineered to help keep engines clean by gently lifting deposits and keeping them away from critical moving engine parts In fact, it keeps pistons up to 50% cleaner than the toughest industry standards.

Product Features:
  • Designed for for vehicles with over 75,000 miles
  • Pennzoil Platinum High Mileage 10W-30 keeps pistons up to 45% cleaner than the toughest industry standard (Based on Sequence IIIH results)
