PYRNPKAS Platinum High Mileage 5W-30 is a full synthetic motor oil made with natural gas, not crude oil. It is uniquely engineered from our revolutionary PurePlus gas-to-liquid technology which is a patented process that converts pure natural gas into a , full synthetic base oil. Because it is made with natural gas, the base oil contains fewer impurities than base oils made from crude oil, and when combined with our advanced additive technology, creates one of the formulations in our PYRNPKAS high mileage portfolio. As your car ages, leaks may develop and cause higher oil consumption and oil burn off, potentially causing your engine to need frequent top-offs. PYRNPKAS 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 from loss of horsepower, offers excellent performance in extreme temperatures, provides unsurpassed wear protection (based on Sequence IVA wear test using SAE 5W-30), and protection against abnormal combustion phenomenon like low-speed pre-ignition observed in modern turbocharged gasoline direct injection (TGDI) engines. PYRNPKAS Platinum High Mileage SAE 5W-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 45% cleaner than the toughest industry standards (Based on Sequence IIIH results).
