Gasoline Oe Motor Oil. Advanced wear Protection Provides 100% synthetic engine protection for advanced automotive technology, including turbos and direct injection. Specifically formulated for the longer drain intervals recommended by original equipment (OE) manufacturers. Fights sludge and deposits with 100% synthetic formulation. 47% more wear protection than required by the GM dexos1 Gen 2 specification. 100% protection against LSPI2 in the engine test required by the GM dexos1 Gen 2 specification. Protects Pistons from Low-Speed Pre-Ignition Includes unique chemistry to protect against low-speed pre-ignition (LSPI). Achieved 100 percent protection against LSPI2 in the engine test required by the GM dexos1 Gen 2 specification. Zero occurrences of LSPI were recorded throughout five consecutive tests. Keeps Engine Cleans Engineered to remove harmful contaminants. Synthetic base oils naturally resist chemical breakdown to help prevent deposits. Detergent and dispersant additives provide excellent sludge- and deposit-fighting properties. Protects in all Temperatures Suited to today's hotter-running engines. Fights heat to control deposits, prevent thickening and limit oil consumption. Easier cold starts and rapid lubrication of components to reduce start-up wear. Improves Fuel Economy & Maintains Low Emmisions Licensed by the American Petroleum Institute (API) to meet and exceed common OEM requirements. Excels in fuel-economy testing, earning the additional "Resource Conserving" designation from the API. Promotes proper operation of catalytic converters for best-fit service life and low exhaust emissions.
