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 LL-A-025, 6094M and 4718M)
• ACEA A1/B1,A5/B5
• Chrysler MS-6395
• Ford WSS-M2C946-A, WSS-M2C929-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've been using Amsoil products since shortly after they hit the market, and have never had a regret. It's the best of the best. I've never had any kind of failure in any engine that was using Amsoil, even though I sometimes went over the recommended mileage or time limit. My first usage was in motorcycles like the old Honda CB-750F, etc. many decades ago. Back then, the oil filtration systems were poor at best and with conventional oil they became very dirty and gummy inside. Once I switched the first one to Amsoil, and ran if for a long duration before checking the oil, I was shocked to find the oil up in the valve train pristine clean with no gumming, etc., and I was hooked. And, everything I used Amsoil in returned better performance and RPM increase to the point that it had to be turned down. There is no better lubrication product on the market......period.

Without testing it is hard to know exactly what the oil is doing for your engine. But when I drain the oil it still looks fairly clean unlike most other oils I've used. And the engine never uses any oil between changes. Being that it is on an older Toyota I have to change the oil every five to six thousand miles. And if by feel you can tell anything about an oil I do not know, but this stuff is the slipperiest oil I've ever felt. :-)

I am not a chemist or engineer, so I cannot speak as to what's inside the bottle. However I am a mechanic and can speak as to what's inside a engine, transmission or differential. I've used Amsoil on and off over the years alone with other bands of synthetic and conventional oils. I've never used anything that didn't work. However, I've found good oils last longer. Being a fleet mechanic I change a lot of oil and get to see what it looks like under abuse. Amsoil always holds up. That's why I use it.

I ran a purple brand for 10 years. I've always heard good things about Amsoil so after feeling like the product quality of my previous brand was going downhill I decided to try it out. As a preferred customer I can get Amsoil cheaper than my previous brand. My truck runs smoother with less engine noise. Great product with superior performance!

I have tried many types of oils and read a ton of reviews, which can be hard to decipher with everyone giving their personal comments and feelings. But hands-down without a doubt Amsoil is the best product out there, tested over and over again. I know this is the only oil I will trust in my vehicles.
Now, I wish Amsoil will create their own waterless radiator fluid so that everyone will enjoy all the fluids in their cars are coming from a trusted source.

This is just one of Amsoil products that I use. I have used Amsoil synthetic oil for 20 years, and every time I get a new or used vehicle, I waste no time in switching the crankcase to Amsoil. I have 267,000 miles on my 2005 Camry, used Amsoil since it had 300 miles on the speedo, and it's still purring like a kitten and not burning oil. I am a very satisfied customer.

I have used other oils but was sold on Amsoil after a cross country trip where unbeknownst to me all the coolant leaked out of my vehicle. I never noticed because my engine never got hot. I drove all the way through the Great Smokey Mountains and hot Texas heat without my diesel engine ever getting hot even though I was towing a trailer. Great Stuff. Thats the kind of performance I like.

Years ago I use to race & rebuild our engines. Rod bearings and piston rings would wear and need to be replaced quite often. Once I converted to 100% synthetic Amsoil oil I could run a full season on the same bearings and piston rings, savings in $$ and time replacing rings and bearings. Virtually NO wear on moving parts. This proved to me how valuable the oil is and I now run 100% synthetic Amsoil in all my internal combustion engines.

I had always purchased the top-line signature-series for my cars and trucks in order to take advantage of their long drain intervals.
Recently I bought a new midsize truck with a V6 engine. The dealer offers a free one-million-mile powertrain warranty to the first owner. Owner must follow the factory-recommended service intervals; oil drain and filter come every 5,000 miles.
I went with OE because it has to be drained so often, but would it provide about the same protection and mileage as the SS? Before OE the mileage average was 23.4 mpg. After 5,000 miles on OE the mileage average is 24.3, an increase of about 9%. The engine is very quiet at idle and runs very strong. No oil seeping anywhere.

Have been using this product in our 2007 Tahoe with a 5.3, and my 2012 Chev. 2500 with a 6.0 liter gas engine. Very particular about everything, Watch for new leaks, old seeps, consumption, color, smell, everything. Tahoe has 80,000 miles, PU has 60,000 miles. Tahoe has had a slight seepage around rear main area and also had started using a quart of oil in 3,800 miles after every oil change at about 30,000 miles. Since switching to AMSOIL, seepage has just about completely stopped, and consumption has slowed to approx. 1/2 quart at 3,800 miles after about a year and a half of usage and 3 oil changes at 4,000 miles. Hoping for continued improvement with time and miles. PU has never used a drop or leaked a drop between changes. Have always used Valvoline products prior to trying AMSOIL. Still watching results and hoping for the best. Also put 50 wt. SYN. AMSOIL in my '80 diesel truck transmission and saw easier, faster shifting, and less noise. No leaks.
