OE Synthetic Motor Oil provides excellent wear control and protects critical engine parts like pistons and cams. This added protection is particularly important in the extreme environments produced by today’s smaller displacement engines that often run lower viscosity oil. Camshaft wear can result in poor valve timing, greatly reducing engine efficiency and leading to expensive repairs. The Peugeot TU3M Wear Test (CEC L-38-A-94), which must be passed to meet the GM* dexos1® Gen 2 specification, determines a motor oil's ability to limit wear. For 100 hours the four-cylinder test engine is subjected to extreme, wear-inducing conditions. AMSOIL OE Motor Oil provided 47 percent more wear protection1 than required by the GM dexos1 Gen 2 specification.

OE Synthetic Motor Oil features unique chemistry proven to protect your engine against the harmful effects of low-speed pre-ignition (LSPI). LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. Most new engines feature gasoline direct injection (GDI), often coupled with a turbocharger. These technologies heighten the possibility of LSPI events, which can destroy pistons and connecting rods. A properly formulated motor oil is critical for protecting your engine against LSPI.Original equipment manufacturers (OEMs) like GM have addressed the issue by designing tests to determine a motor oil's ability to prevent LSPI. OE Synthetic Motor Oil achieved 100 percent protection against LSPI2 in the engine test required by the GM dexos1 Gen 2 specification– zero occurrences were recorded throughout five consecutive tests.

OE Synthetic Motor Oil has a 100 percent synthetic, pure chemical structure that is engineered to remove harmful contaminants. Its synthetic base oils naturally resist chemical breakdown to help prevent deposits. Its detergent and dispersant additives give OE excellent sludge and deposit fighting properties. OE Synthetic Motor Oil helps keep your engine clean, reliable and running at peak performance.

Synthetic base oils and an advanced additive package make OE Synthetic Motor Oil ideal for today's hotter running engines. It effectively fights heat to control deposits, prevent thickening and limit oil consumption. OE's uniform structure keeps it fluid in low temperatures for easier cold starts and rapid lubrication of components to reduce start-up wear.

OE Synthetic Motor Oil is licensed by the American Petroleum Institute (API) to meet and exceed the requirements commonly found in owner's manuals. It excels in fuel-economy testing, earning the additional "Resource Conserving" designation from the API. OE is also friendly toward modern emissions-control systems, promoting proper operation of catalytic converters for optimum service life and low exhaust emissions.
