Royal Purple High Performance Motor Oil

Royal Purple blends top-tier synthetic base oils with exclusive additives to surpass the needs of contemporary engines, often featuring compact designs, turbochargers, gasoline direct injection (GDI), and start/stop systems. Today's GDI engines achieve unprecedented power and fuel efficiency in passenger cars, yet they subject smaller engines to elevated stress levels across all RPM ranges. This heightened strain leads to accelerated wear in critical engine components and triggers a harmful occurrence known as low-speed pre-ignition (LSPI). Royal Purple's cutting-edge additive technology is tailor-made to combat these challenges, ensuring engines uphold their performance and dependability.

Royal Purple High Performance Motor Oil 5W-30 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.
