Royal Purple Premium Synthetic High Performance Straight-Grade SAE 50 Motor Oil - 5 Gallon

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.

• Enhanced Engine Performance
• Optimized Fuel Economy
• Long-term Protection
