High Performance Motor Oil API LICENSED MOTOR OIL Royal Purple High Performance Motor Oil combines premium base oils with proprietary additive technologies to create a high performance synthetic engine oil that optimizes performance and protection. Royal Purple High Performance Motor Oils carry the current API and ILSAC engine oil licenses, as well as the GM dexos1 gasoline engine oil approval. ILSAC GF-6 AND GM DEXOS1 Modern gasoline direct injection (GDI) engines have achieved levels of power and fuel economy never before possible in passenger car engines. As a result, smaller engines operate at much higher loads across all engine speeds. This has caused increased wear in critical areas of the engine, and created a destructive phenomenon called low-speed pre-ignition (LSPI). The unique, state-of-the-art additive technology in Royal Purple High Performance engine oils is designed specifically to address these issues, and help engines maintain performance and reliability.
