Prime Series Conventional Motor Oil SAE 10W-30 (12 pk., 1-qt. bottles)

Minimize start-up wear Increase sludge protection Reduce oil consumption Enhance piston cleanliness API Service SN, SM, SL ILSAC GF-5 Prime Series Conventional Motor Oil's anti-wear additives provide excellent wear protection of critical engine parts. A high level of dispersancy in Prime Series Motor Oils protects against deposit and sludge formation in stop-and-go driving, sustained high-temperature operation, and protects against corrosion. Their excellent high-temperature oxidation stability helps prevent viscosity increase and oil gelling in the crankcase. They help keep PCV systems clean to maintain smooth engine performance. SAE 10W-30 is suitable for use in many older vehicles and a few late model cars and trucks, often those with larger 6-cylinder and V-8 high-performance engines. SAE 10W-30 is also designated as a "resource-conserving lubricant" by API. Prime Series is a precision engineered, high-quality, high detergent multi-grade motor oil High viscosity index mineral oils, combined with a carefully selected additive package Outstanding protection against wear, rust, corrosion, oxidative thickening, acid formation, sludge and varnish deposits Exceeds API Service SN and all previous categories
