Product Applications

Use AMSOIL XL Synthetic Motor Oil in applications that require any of the following specifications:

Product Application Specs

• API SN (Resource Conserving), SM
• ACEA A1/B1
• Chrysler MS-6395
• Ford WSSM2C947-A
• ILSAC GF-5, GF-4
• GM dexos1 Gen 2 (supersedes 6094M) Fortified with detergents that exceed the dexos1 Gen 2 sulfated ash specification.

Product Description

Motorists, business owners and fleet managers benefit from the boosted engine protection of AMSOIL XL Synthetic Motor Oil. Frequent oil changes are expensive, time-consuming and inconvenient. The extra protection built into XL can provide extended drain intervals up to 12,000 miles / 19,000 kms or one year, if you choose, allowing you to change oil on your schedule, reduce maintenance, save money and reduce waste oil.

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.

Resists Oil Breakdown

XL Synthetic Motor Oil maintains its fluidity (viscosity) under the most extreme conditions. Some oils break down and significantly increase in viscosity after extended periods of high-temperature operation. These changes can cause excessive oil consumption, engine deposits, accelerated wear and difficult cold-starts. The GM Oxidation and Deposit (GMOD) Test consists of a 5.7L V8 engine running at 293°F (100° hotter than normal) for 100 hours. These severe operating conditions test an oils ability to control viscosity increase, deposits and oil consumption. The testing revealed that AMSOIL XL Synthetic Motor Oil provides 64 percent more protection against oil breakdown1 than required by the GM dexos1® Gen 2 specification, ensuring protection in extreme temperatures.

GM Oxidation and Deposit Test Results

Protects Pistons from Low-Speed Pre-Ignition (LSPI)

XL 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-inject (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. XL Synthetic Motor Oil achieved 100 percent protection against LSPI2 - zero occurrences were recorded throughout five consecutive tests.

Keeps Engines Clean

AMSOIL XL Synthetic Motor Oil is fortified with detergent and dispersant additives. Its boosted additive package effectively raises the total base number (TBN) to neutralize acids and resist sludge, corrosion and carbon deposits. XL provides 25 percent more cleaning power3 to help keep your engine running smoother, longer.

Hot and Cold-Engine Protection

AMSOIL XL Synthetic Motor Oils are multi-viscosity formulations. Compared to conventional oils, they better resist the effects of thermal breakdown, including evaporation and viscosity loss, while remaining fluid in cold temperatures for easier cold starts and fast start-up circulation.

Maximizes Fuel Economy & Maintains Low Emissions

XL Synthetic Motor Oil is licenced 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" designation4 from the API. XL is also friendly toward modern emissions control systems, promoting proper operation of catalytic converters for optimum service life and low exhaust emissions.

1 Based on independent testing of AMSOIL XL 5W-30 motor oil in the GMOD engine test required for the GM dexos1 Gen2 specification.

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

COMPATIBILITY & MIXING AMSOIL

AMSOIL XL Synthetic Motor Oil is compatible with conventional and other synthetic motor oils. Mixing other oils with AMSOIL motor oils, however, will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL XL Synthetic Motor Oil.

I won't run anything else in my truck

I use this oil in my 2013 Toyota tundra and have been changing it around 8000 miles every time and every time I drain it the oil has never come out black it always has a little bit of an amberish tint left which makes me think that it could hold up well past the recommended 10000 mile change intervals.

Best darn oil on the planet!

I started using synthetic oil in the late 90s after observing the inside of gearboxes that used regular gear oil compared to the ones that had been switched to synthetic. The difference was astonishing. I started with Mobil 1 and I have used various brands but none can compare to the quality and reliability of Amsoil. I started using Amsoil on my new 2007 Camry which my son has now and then on my new 2011 Camry. On the 2011 I have changed the transmission fluid with your premium fluid. (Even though it is supposedly lifetime fluid) My 2011 Camry now has 174,000 miles and it still runs and shifts like new. The 2007 has over 200,000 miles and runs great. I bought a used 2004 Silverado with 84,000 miles and switched it over to Amsoil. After about 500 miles I noticed that my oil pressure had dropped by almost 50 percent. I drained the oil and pulled the filter and a thick slime was in the filter and in the oil. It took 2 more oil and filter changes but eventually your product cleared out all the built-up sludge from the engine. My oil pressure increased even more and has remained steady ever since. Fantastic product.

Basic Excellence

This is in my daughters 2012 Honda Accord. Since we will be changing the oil according to on board diagnostic recommendation I went with this lower priced alternative to the signature line I use in my other vehicles that go a full 12 months between oil changes. I have no reason to doubt this oil will work as well as the other have for my vehicles in the more than 10 years I have been using AMSOIL.

Proud Amsoil Customer

I use Amsoil in all my vehicles. Oil retains viscosity better then I even hoped. I do change at the recommended manufacture interval, but it is noticeable especially in my Turbo vehicle toward the end of the interval the manufacture oil would start to break down and Amsoil has maintained consistency.

Changed my second car to AmsOil after maintenance ended

I've been using AmsOil for my Subaru Impreza WRX since 2005 and when our family truck, the 2008 Toyota Sequoia finally used up the extended maintenance service contract in 2013, I started performing the oil changes myself with AmsOil XL products. Since my WRX has been on this synthetic oil for many years, I figured having both vehicles on the same oil would be the best thing I could do for them to keep them performing at their best. It's been the best feeling to be able to treat the cars with these proven and high quality products, specially Oil and Oil Filters on both my cars. I don't feel bad if I push the cars a bit or if I miss the change interval by a few thousand miles, although that is rare, but I have a sense of trust that it will continue to protect the engine even if I slip a bit.
glad to be using these products.

Best synthetic ever made.!

I started using the longer interval synthetic oil recently and did notice my gas mileage improved along with the engine running very smooth. I have to admit at first I was not sure Amsoil was able to produce a oil that could go for 10,000 miles and beyond. I took the plunge into using a longer time interval change for my car. Amsoil is a company that has dedicated probably countless hours of coming up with a synthetic that can in the real world condition do this. I have taken care of every car I've own since I want them to last me a long time. When the most recent oil change was done I was very impressed on how good the oil looked after. I recommend this oil to all my friends but some you can convince and some remain sceptable. As they say you can lead a horse to water. So I cleaned the throttle body, changed the oil and entered into my maintenance log. If you are on the fence about trying their products, trust me. Become a yearly member and you probably will not go back to whatever oil you were using. I feel Amsoil needs to keep their prices lower for members as they have done so that more people will be able to switch over without question. Cost will always be the factor on if the consumer will give the product a try. I think free shipping, reward points and sales would give existing members to purchase more in advance. Thank you to the entire Amsoil team for their commitment to protecting our engines.

Best engine oil

I used Signature Series 0W-30 for 70,000 highway miles in my motorhome. When I bought my 2016 Subaru Outback, ( which calls for synthetic 0W-20), I wanted to use Amsoil in it. I have 2 free service but I buy Amsoil 0W-20 and the appropriate filter and give it to the service dept to put in my car. I think Subaru's synthetic oil is made in Canada. I trust Amsoil and not some oil I've never heard of and don't know anything about.

Not even a question, Oil changes with Amsoil only.

I have used Amsoil for years, with zero failures related to lubrication in any of the vehicles, I have "amsoiled" Built three LS motors with this as the break in, and beyond. Drove these motors HARD and when doing some upgrades on one we were all amazed that the internals looked as they had when built and the micrometer showed nearly unreadable wear after 30K of performance driving. Just bought a 65K Tahoe with all the toys, the first thing done, tinted windows and full amsoil change out, Oil, diff's, trans, PS, you name it... done.. Why... because I have a known quality product in place of what I'm sure was just fine factory fluids BUT... It is done with something I know and trust, simple as that.
