OE 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.
Package sizes include:
1-Quart Bottle
1-Quart Bottles (case of 12)
30-Gallon Drum
55-Gallon Drum
AMSOIL OE Synthetic Motor Oils are excellent for use in all types of gasoline-fueled vehicles. They are recommended for all domestic and foreign vehicles requiring any of the listed performance specifications:
• API SN (Resource Conserving), SM
• GM dexos1 Gen 2 (supersedes 6094M)
• ACEA A1/B1
• Chrysler MS-6395
• Ford WSS-M2C945-A, WSS-M2C930-A
• ILSAC GF-5, GF-4
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.
1 Based on independent testing of OE 0W-20 in the Peugeot TU3M Wear Test as required by the dexos1 Gen 2 specification.
2 Based 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.
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.
*All trademarked names are the property of their respective owners and may be registered marks in some countries. No affiliation or endorsement claim, express or implied, is made by their use.
AMSOIL OE Synthetic Motor Oil is compatible with other synthetic and conventional motor oils. Adding other oils, however, will shorten the life expectancy of AMSOIL motor oils and reduce their performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
Aftermarket oil additives are not recommended for use with AMSOIL OE Synthetic Motor Oil.
In gasoline-fueled vehicles, AMSOIL OE Synthetic Motor Oil is recommended for the intervals stated by the vehicle manufacturer or indicated by the oil life monitoring system. Change oil filter at every oil change.
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

I use this oil for our daily driven family car and it has worked great. I've used it almost since we got the vehicle so looking forward to seeing the long term benefits Amsoil is known for. I also purchased because I don't necessarily need long interval oil like signature series as well as more mileage. We use the car maybe 10k kms a year at most. Also, Its cheaper for this full synthetic than buying at a parts house locally. It in many cases is the same or cheaper than semi-synthetics. Great stuff.
