Royal Purple High Performance Motor Oil

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.

• Royal Purple High Performance Motor Oil 5W-20 Premium Synthetic Motor Oil, 5 Quarts
• 300% BETTER OXIDATION RESISTANCE ? Maximum protection from oil breakdown.
• 100% LOW SPEED PRE-IGNITION PROTECTION? Prohibits major damage to cylinder walls, pistons, piston rings, connecting rods and spark plugs, maximizing engine life.
• 14% ENHANCED SLUDGE PROTECTION ? Cleaner engines operate more efficiently, lowering operating temperatures
• BETTER WEAR PROTECTION ? Enhanced additive technology prevents metal-to-metal contact beyond both GM dexos1* and ILSAC GF-6A specs
• INCREASED FUEL EFFICIENCY ? A low coefficient of friction results in optimized fuel efficiency (our 5W-30 meets the fuel economy requirements of a 0W-20 oil; our 0W-20 meets fuel economy requirements of a 0W-16)
• BETTER PROTECTION FOR VEHICLE EXHAUST EMISSIONS EQUIPMENT ? Patented anti-wear additive chemistry minimizes the harmful effects exhaust gases pose to the catalyst
• IMPROVED COMPATIBILITY WITH FUELS CONTAINING ETHANOL ? Patented additive technology prevents the white sludge and lubrication starvation that can occur with higher concentration gasoline-ethanol blends
• SUPERIOR CORROSION PROTECTION ? No rust observed in standard industry testing
• Royal Purple High Performance engine oils carry the current API and ILSAC engine oil licenses, as well as the GM dexos1* gasoline engine oil approval.
• *dexos1 is a registered trademark of the General Motors LLC. **Comparisons based on dexos1 Gen3, API SP and SN+, and/or ILSAC GF-6A requirements
