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:
1-Quart Bottle
1-Quart Bottles (case of 12)

1-Gallon Bottles (case of 4)
30-Gallon Drum

Use AMSOIL XL Synthetic Motor Oil in applications that require any of the following specifications:
XLM 5W-30 Synthetic Motor Oil
• API SN (Resource Conserving), SM
• ACEA A1/B1 A5/B5
• Ford WSS-M2C946-A, WSS-M2C929-A
• Chrysler MS-6395
• Honda HTO-06
• ILSAC GF-5, GF-4
• GM dexos1 Gen 2 (supersedes LL-A-025, 6094M and 4718M) 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 12,000-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.

Upon cleaning out the oil drain pan, the used Amsoil oil was so slick, it actually appeared to not have broken down at all. Don't buy any other product, buy Amsoil and you too will use nothing else.

I have been a mechanic for over 40 years on everything from lawnmowers to autos and mostly class 8 trucks with Cummins, cats, Detroits both 2 and 4 stroke, Mack and Volvo diesels. also every type of heavy equipment from all the major manufacturers. I have rebuilt hundreds of gasoline and diesel engines. I know very well how important top quality engine oil is but I didn't think you could hear a difference in engine sound until I put 0w20 xl amsoil in my 2011 honda crv with 110,000 miles on it. I didn't expect to feel or hear any difference as I never did at any other oil change in my life but the first time I brought it up to speed on the highway it sounded quieter than usual so I done a few rapid accelerations and was convinced it was definitely quieter so I changed it in my 2012 crv with the same results. This amazes me that oil can make this difference as after thousands of oil changes in my life I had never experienced this before.

All my cars (well, except for the ones with mileage above 400,000 km) and motorcycles get synthetic oils in them. When I can get Amsoil, that is my oil of choice.

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!

When I bought my 2004 Subaru Impreza WRX back in 2004, I wanted to use the best motor oil around to keep it performing at it's peak. I tried other brands of synthetic motor oil first and then found out about AmsOil while looking online to try and find the best. I then asked some co-workers about it and started to understand more about the company and the products offered. I signed up for a membership and ordered the regular synthetic from AmsOil and I could feel the difference from the other brands while driving my WRX. I eventually went with the XL product and extended the oil change intervals to between 5,000 - 7,000 miles on my car. My 2004 was totaled recently in an accident and now have a 2017 WRX which I plan to continue treating it to AmsOil XL synthetic oil while I have it.
As long as the prices for products remains competitive, I know what I'll be buying for my cars.

I have been using XL 5W-30 in a Chevy Vortec 8.1 L V8 and in several automobiles for several years. It has kept my engines squeaky clean and running. This is a solid motor oil. I change oil every 6 months which sometimes gets a little over the limit for miles (6k to 8k), but the oil could withstand many more miles it is so strong.
Recently, I serviced a 5.3 L Chevy Vortec that we had no service records for. The engine was not running well and we took it to a dealer who said they would have to replace the oil pump. I knew the oil pump was ok and explained to them that the oil pressure was going up and down, indicating a bad sender unit, but they wouldn't even try.
I took the vehicle back, drained out half the oil and replaced it with ATF and ran it for several minutes. The oil pressure came back after about a minute and hasn't been any trouble since. I then changed the oil/filter and put in 6 qts of XL 5W-30. It runs like a new engine. The engine had 237,000 miles and my guess is that it had been serviced with some standard brand of oil, which is fine for most engines, but not this brand. It was so chocked full of crud that when I put a good synthetic (not Amsoil, the owner provided the oil) in it, it loosened all the stuff up but couldn't deal with it. The ATF cleaned everything out and the XL 5W-30 cleaned the rest and makes her purr.
I have never found a better oil than this for the price.
