AMSOIL XL Synthetic Motor Oil is the choice for those who want to do something extra for their vehicle. Its boosted formulation delivers extra cleaning power, outstanding wear control, excellent high and low temperature protection and exceptional fuel economy. XL is engineered for advanced automotive technology, including turbos and direct injection. It is packed with extra engine protection, allowing you to go up to 12,000 miles / 19,000 kms or one year, whichever comes first, between oil changes.
Package sizes include:
Quart Bottle
Gallon Bottle
30-Gallon Drum
55-Gallon Drum
Use AMSOIL XL Synthetic Motor Oil in applications that require any of the following specifications:
• 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.
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.
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.
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.
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.
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.
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.
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.
For immediate answers to your technical questions call (715) 399-TECH (8324) between 8 a.m. and 5 p.m. Central time or email tech@amsoil.com.
In gasoline-fueled vehicles, AMSOIL XL Synthetic Motor Oils are recommended for up tp 10,000-mile/six-month oil change intervals or longer when recommended in owner's manuals or indicated by electronic oil life monitoring systems. Change aftermarket, original equipment manufacturer or AMSOIL Ea 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).

Look my friends, if you have searched for the best oil on the internet for countless hours as I have, AMSOIL is truly the best you can get so stop searching and just get it. I have tried many, many other brands and nothing I have ever used even comes close to AMSOIL. I use AMSOIL products in all of my small engines, lawnmowers, weed eater, pressure washer, generator, as well as my personally owned vehicles. This stuff is the real deal and doesn't evaporate, and does just what is it is supposed to do, that is, protect your equipment/vehicles. Don't waste your time and money looking elsewhere, just give AMSOIL a try and you wont use anything else. I have been down the road looking for the best protection and have finally found it in AMSOIL products. Thank you AMSOIL.

I used to buy the AMSOIL Signature version of the 0W-20 that my truck calls for, but I switched to this to save about 50% on the cost. I get about 6k miles between oil changes (changing at the 20% oil life remaining mark) and it appears I'll get that same interval maybe a bit more (maybe 500-750 extra miles) with this grade oil vice the Signature.

Ok, I am an Amsoil customer for life... Seriously! In February when it was still wicked cold here in Maine, I was having some engine starting and idling problems with my SUV when the overnight temperatures were 15F and colder. The engine would default to a safe "limp home" mode, and I was facing some expensive engine overhaul costs. My mechanic was very sure the symptoms had to do with dirty cam phasers. He suggested using Amsoil Engine and Transmission Flush to clean the engine (including the cam phasers) and switch to Amsoil Signature Series Synthetic Oil. I followed his advice and the results have been AMAZING! After the treatment I have had zero starting problems. And even better, the rattling sound that I thought was the water pump turned out to be the timing chain... no more noise! The Amsoil Engine Flush and motor oil solved both problems and they have given my 135K mile engine new life. I plan to treat all of my vehicles with these Amsoil products, and that includes the transmissions as well. If that wasn't reason enough to use Amsoil products, when I made my first purchase I decided to register as an Amsoil Preferred Customer. I saved much, much more than the registration fee over the cost of Amsoil products at the local auto parts store on that first purchase alone. Engine problem solved and low prices equal CUSTOMER FOR LIFE!! Thanks Amsoil!

Then I bought a new truck and thought to myself that I'm really going to have to take care of this thing because I probably wouldn't be able to buy another one in this lifetime due to cost and old age. If the data I had seen was accurate than Amsoil was the direction I needed to go for protection. I used the factory oil for 4900 miles then made the switch to Amsoil. So far I'm very pleased. Most notably with the fuel economy. I've gained 1.5 to 2.0 MPG in highway driving. That to me is impressive. I'm sold.

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.

I have been using this oil in my present 2012 Honda Pilot since I bought it and is excellent oil. I also used it in my 2000 Acura TL for about 4 years before I sold it. Never an issue with oil problems using this oil..

Purchased the product for my 2015 Subaru. I have used Amsoil products in all my vehicles, including motorcycles, for many years. Have never had a problem that was oil related. I am very pleased with Amsoil products.

I've been using Amsoil XL motor oils and EA filters now for over 10 years in all my vehicles and small engines such as lawn tractor, snowblower, etc. The lawn tractor is a John Deere and is 32 years old. Engine still runs strong. All engines appear to be wearing just fine and the internals remain extremely clean. I change oil and filters in my on-road vehicles every 6000 to 7500 miles. Great products, and I will continue to use the XL motor oils because of their excellent price/performance value.

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.

I routinely run this oil for 10,000 miles with a filter change @5,000 miles. Oil analysis @17,000 miles shows continued protection with acceptable metal wear and good TBN levels so I run the 10,000 mile schedule without hesitation. Amsoil always produces quality products!

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.

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.
