Royal Purple combines premium synthetic base oils with advanced additive technologies to surpass the protection and performance requirements of modern engines, which often feature smaller displacements, turbochargers, gasoline direct injection (GDI), and start/stop systems.  GDI engines have revolutionized power and fuel efficiency in passenger cars, but they subject smaller engines to higher loads at all speeds, leading to increased wear in critical areas and the development of low-speed pre-ignition (LSPI). Royal Purple's state-of-the-art additive technology is uniquely designed to counter these challenges, ensuring engines maintain optimal performance and reliability.
