AMSOIL OE 5W-30 100% Synthetic Motor Oil

Delivers 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.

Advanced Wear Protection

• Excellent wear control to protect critical engine parts like pistons and cams.
• 47 percent more wear protection¹ than required by the GM dexos1 Gen 2 specification.
• Added protection in extreme environments produced by smaller displacement engines.

Protects Pistons From Low-Speed Pre-Ignition

• Features 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 Engines Clean

• 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

• Ideal for 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 And Maintains Low Emissions

• 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 optimum service life and low exhaust emissions.
