Our product for lube centers, retailers and the oil where customers buy based on price

API Certified 5W-30 Synthetic Motor Oil (OEF)

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

Formulated for Excellent Engine Protection and Performance
AMSOIL OE Synthetic Motor Oils help provide better wear control, high- and low-temperature protection and increased fuel economy compared to conventional oils. The oil drain interval recommendations for many of today’s vehicles extend well beyond the traditional 3,000-mile interval, some up to 12,000 miles with electronic oil monitoring systems. AMSOIL OE Oils provide excellent protection and performance for the entire length of the original equipment manufacturer’s recommended drain interval.

AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, The First in Synthetics®, to do the best job protecting your engine.


Provides Advanced Wear Protection

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.

Protects Pistons from Low-Speed Pre-Ignition

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.

Keeps Engines Clean

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.

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.

Improves Fuel Economy & Maintains Low Emissions

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.

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.

OE line Reviews


Works great in the Volvo T5/ 2.5T engine.

By  BRIAN,  a  Verified Buyer  from  The Carolinas  on  January 08, 2024

I have been using OE 5W-30 in the old P2 Volvo 5 cylinder turbo wagon (XC70) for over six years. The wagon has over 280,000 miles on it and it still runs strong. I change the oil and filter every 5K. OE is great oil at a great value.

Best oil

By  JERRY,  a  Verified Buyer  on  December 30, 2023

So far this is the best oil I have ever used. I can feel and hear the difference in the engine and exhaust. Cost more than your typical oil but it’s worth it. I would refer this oil to all my family and friends. Thank you for making a great product!

Runs like new

By  Eric,  a  Verified Buyer  from  Utah  on  December 08, 2023

Instead of paying for another overpriced oil change at the dealership, I wanted to give this a try and see if it lived up to the hype. I feel as though the engine runs smoother compared to the oil changes I got at the dealership. I like knowing that I am putting true synthetic in and getting the protection to help my engine last longer. Will be purchasing again.

Runs Smooth

By  NICK,  a  Verified Buyer  from  Greeley,CO  on  December 13, 2023

Been using Amsoil for about 3 years now, and my Subaru runs stronger and longer. Boost in gas miles and no pinging.
