OE 5W-20 100% Synthetic Motor Oil 

No other product comes close on price for a true 100% synthetic. Any competitor product in this price segment will still be 100% Group III or have a very slight amount of Group IV. Thus the performance will not be equal. Plus for the price this is the only oil in the market to protect 100% the issue of LSPI. (Low Speed Pre-Ignition)  Call us at 800-579-0580 as this is the best synthetic for lube centers to offer as a true synthetic upgrade at a price conventional users will gladly upgrade too.

OE (Original Equipment) 5W-20  Synthetic Motor Oil is for mechanics and drivers seeking peace of mind protection and exceptional value in synthetic motor oil. It delivers 100 percent synthetic engine protection for advanced automotive technology, including turbochargers and direct injection. OE is specifically formulated for the longer drain intervals recommended by original equipment (OE) manufacturers.

Provides Advanced Wear Protection

 OE 5W-20 Synthetic Motor Oil This OE 5W-30 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.

Protects Pistons from Low-Speed Pre-Ignition

The OE Line of Synthetic Motor Oils 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.

Keeps Engines Clean

OE Original Equipment 5w-20 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.

Protects in All Temperatures

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. Remember those competing products called “fully Synthetic” will thicken and leave deposits should you have the most minor overheating or imminent engine problem. That’s why AMSOIL was developed, to safeguard you when these things happen.

Improves Fuel Economy & Maintains Low Emissions

OE Synthetic 5W-20 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.

1Based on independent testing of OE 0W-20 in the Peugeot TU3M Wear Test as required by the dexos1 Gen 2 specification.

2Based on zero LSPI events in five consecutive tests of AMSOIL OE 5W-30 Motor Oil in the LSPI engine test required by the GM dexos1 Gen 2 specification.
