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.

Amzoil to keep my high performance WRX humming

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.

Used this product for my 2008 350z Roadster, this is the second go runaround with this product. I have noticed my engine runs smother and idles better (66,100 plus miles). I used other brands of synthetic oils on my prior vehicles (Mobil1, Royal Purple, Castrol) but by far I am the most satisfied with Amsoil. I want to use the best product available and so far this is the best to me until otherwise. I have not performed any lab test or chemical analysis but real life driving. Also I need to mention better gas mileage, how I know I am getting better gas mileage? I know because I do not fill my tank as often (i use Premium that is what Nissan requires for maximum performance) I wish Amsoil had a high-performance filter like K&N or aFE, I would buy it too

When I first switched to it, I kept careful MPG records and found that the increase in mileage with Amsoil more than offset the higher cost of the synthetic usage. What's more important, oil consumption in both cars between oil changes (6,000 miles on average, which I arrived at as a time for changes based on lab analysis of the used oil) has been zero, even when my last car was up at 200,000+ miles.

Great Products

I bought a 2005 GMC Serra 1500 new in November 2004. I have used XL5-30 and wix oil filter ever sense the first oil change. It now has 183000 miles on it and other than a set of spark plugs (it's due for another) the motor has been untouched and runs great dose not use but half a quart of oil between oil changes (every six months).
I also have changed the transmission fluid twice and used am soil transmission fluid and wix filter and the fluid is always nice and red and no transmission problems.
My 1996 Harley Davidson electraglide has been running on 20-50 V-twin oil in the motor, tranny, and primary for years again no problems great stuff !

Still using Amsoil

Many years ago I had an 87 ford f150 with lifter noise at 100k miles. I ran across an Amsoil dist. at that time, I changed to Amsoil, noise went away and I put another 150k miles on the truck and the engine was still quiet when I sold it. All I ever did to it was a new timing chain. Been using Amsoil ever since in every vehicle.

For years, I used mobil1. When the time came, I switched to Mobil 1 high mileage. About 2 years ago I started to get a subtle knock coming from the bottom end of the motor. It also started to use oil between oil changes. When I switched to Amsoil, not only did the knock go away immediately, my now 170,000 mile engine consumes no oil between oil changes.

Great product and made my trip worry-free

This summer I decided to do my #1 bucket list trip of a lifetime and I drove cross-country from Connecticut to Oregon/Washington and everywhere in between. I used amsoil for the first time in my 2013 GMC Terrain (new to me in Feb.) and I drove over 8,000 miles in 3 1/2 weeks. I never had to add any oil and my vehicle ran perfect. I was over 10,900' elevations and others many times on the drive out and back and was in temperatures from 50-95 degrees. I am now hooked on using amsoil in my vehicles and thank my boss for recommending it.

Helping my RallyX car scream

I have always used synthetics in my motors and never miss a beat when it comes to maintenance. I recently started racing RallyX with my wife and I have heard great things about Amsoil so I thought we would give it a try. I had no idea what we were missing out on. Basically it took the motors efficiency and turned it up to 11. Just changing to Amsoil from one race we were able to push our 88' Mazda 323 motor into a top 5 finish against cars as new as 2016. I now use Amsoil in all my cars and buy oil by the case.

Best oil around for the price

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.

So Far ; So Good

This wasn't my first AMSOIL purchase but lost my local dealer so bit the bullet and became a preferred customer. Just wish I was bright enough to buy some extra oil that I will lose when I do the filter change in 5K miles! DUH! Bought a GM Certified 2011 GMC Canyon with 73,000 miles . I did the AMSOIL engine flush as per instructions and NO; the high mileage engine didn't start weeping oil! Let it drain all day to get the last drop of whatever was in there out. Within the first 500 miles, I can say I am getting noticeable increase in fuel efficiency. I haven't done the math because I don't have a reference for the pre-change MPG. I just know that a tank of gas stretches a bit further. What is also noticeable is the engine seems smoother at startup and runs cooler on the road. Not a very technical review but I can say I've been using and will keep on using this product.

When I had it (Toyota) torn down the shop couldn't believe how clean it was internally.
I have not had my F150 worked on internally because it is still great with over 247,000 miles.
