Royal Purple utilizes premium synthetic base oils along with proprietary additive technologies to surpass the protection and performance demands of modern engines. These engines often feature smaller displacements, turbochargers, gasoline direct injection (GDI), and start/stop systems.  Modern gasoline direct injection (GDI) engines have achieved unprecedented levels of power and fuel efficiency in passenger car engines. However, this progress has led to smaller engines operating at higher loads across all engine speeds. Consequently, critical areas of the engine experience increased wear, and a harmful occurrence known as low-speed pre-ignition (LSPI) has emerged.  The advanced additive technology in Royal Purple High-Performance engine oils is specifically engineered to tackle these challenges, aiding engines in maintaining optimal performance and reliability.
