Royal Purple High Performance 0W-20 is a full synthetic motor oil sold in a 5-quart jug. It is built around a patented anti-wear additive package and is marketed for modern turbocharged, gasoline direct injection and start/stop engines, with a claim of low-speed pre-ignition (LSPI) protection. The 5-quart jug at $19.49 from eBay as of November 5, 2026 is well below what this oil usually costs, so it is worth checking that the listing is genuine and sealed.

Royal Purple High Performance Motor Oil 0W-20 Premium Synthetic Motor Oil, 5 Quarts. Royal Purple uses premium synthetic base oils and proprietary additives to enhance engine protection and performance, especially for modern engines with features like turbochargers, gasoline direct injection (GDI), and start/stop systems. GDI engines have achieved unprecedented power and fuel economy, causing smaller engines to operate under higher loads, leading to increased wear and low-speed pre-ignition (LSPI). Royal Purple High Performance engine oils incorporate advanced additives to address these issues, ensuring engines maintain their performance and reliability. Weight: 10 lbs
