uses premium synthetic base oils and proprietary additives to surpass the protection and performance demands of modern engines, which often feature smaller displacements, turbochargers, gasoline direct injection (GDI), and start/stop systems. Modern GDI engines have achieved unprecedented power and fuel efficiency, but this progress has led to higher loads on smaller engines, increasing wear and causing low-speed pre-ignition (LSPI). The advanced additive technology in High-Performance engine oils is specifically engineered to tackle these challenges, helping engines maintain optimal performance and reliability. Viscosity: 5W-30 Weight: 10 lbs 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 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
