Provides Advanced Wear Protection

OE 5W-30 Synthetic Motor OilOE 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 protection than required by the GM dexos1 Gen 2 specification.

Note on this dexos1 Gen 2

Now to pass Gen2 it’s not a test of no failures but a level of an ok number of failures which are micro detonation events which leave visible damage to pistons. AMSOIL passes without any damage. Real protection not available elsewhere.

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. 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 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.

  • Good initial impression.
    By  Shea,  a  Verified Buyer  on  September 02, 2019
    Bought Amsoil to run in my wife’s new 2019 Subaru Forester. Did a short interval initially to get the engine break in oil out of the car and noticed smoother idle and better gas mileage. I plan on changing all of my vehicles (except for my Subaru STi) and lawn equipment over to Amsoil as I exhaust my oil stash.

    I would recommend you try it, you’ll be glad you did.
    By  Michael,  a  Verified Buyer  on  September 01, 2019
    Used amsoil for decades in a company fleet of 26 construction vehicles, plus my personal fleet of 18 classic and off-road vehicles. Also use 2 stroke lubricants for my outboards. Never lost a engine or gearbox in any of these vehicles as a result of poor lubrication.
  • I would definitely buy this product again!
    By  Van,  a  Verified Buyer  on  July 11, 2019
    Run this in my GMC Sierra, and I plan to continue. Great oil! Reduced lifter noise to almost nothing and oil doesn’t seem to sludge up when going over the service mileage.

    My 2008 Toyota Highlander has 325000 km on it. My oil change interval is every 15000 km. Runs and accelerate as smooth as the day I bought it.

    By  John,  a  Verified Buyer  on  June 27, 2019
    I am now comparing Amsoil with another product on price, life, and evaporation. So far the increase in mileage per gallon is equal. Evaporation will need more miles to be sure, but it looks the same right now. I did not need to add until I had 1500 miles on the new oil. Price: depends on longevity. I changed oil & filter at 7000
