Pennzoil Platinum full synthetic SAE 5W-30 motor oil 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. Our high quality 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 portfolio. Pennzoil Platinum full synthetic SAE 5W-30 motor oil is licensed and meets the vehicle warranty requirements of GM's dexos 1 Gen 2 specifications that are set forth to meet today's modern engine technologies. This means that our Pennzoil Platinum full synthetic products meet the stringent requirements of leading car manufacturers. Why does this matter? Modern engine technologies have evolved over the years and today's engine parts have reached an unprecedented level of fine manufacturing tolerances which require a high-quality engine oil to help provide complete engine protection. This includes protection against abnormal combustion phenomenon like low-speed pre-ignition observed in modern turbocharged gasoline direct injection (TGDI) engines.
