Product Application Specs

XLM 5W-20 Synthetic Motor Oil

• API SN (Resource Conserving), SM
• ACEA A1/B1
• Ford WSS-M2C945-A, WSSM2C930-A

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.

A long time user.

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. Amsoil has been my desired oil for years. Is it better than any other brand of synthetic oil? I don't know from experience, however synthetic oils help my vehicles run cooler, and I believe that synthetic lubricants provide a more consistent layer of lubrication under all conditions of use.

What's not to like.

Is AMSOIL expensive, yeah a little, but if you sign up for the Preferred Customer it not bad. I'm definitely a pay a little more in maintenance and avoid having to pay a lot in repairs.

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. I would buy again for sure.

My next door neighbor got me started using Amsoil some years ago. I now use nothing but Amsoil in all my vehicles. It is an excellent product and it is really cheaper to use than conventional motor oils because of the extended change times. I have run Amsoil as long as 24,000 between changes with no problems. I now change my oil when the vehicle computer tells me it is time to change and that is usually aroung 9,500 to 10,000 miles.

The Right Lubricant for the Job

The Amsoil XL series has protected my vehicles for many years. When the formula was changed to protect against Low Speed Pre Ignition (LSPI) as well as an extended drain interval, I knew it continued to be the right lubricant for the job. Recently I purchased a pickup truck that could be vulnerable to LSPI so this formula change was very timely. I appreciate that Amsoil offers many choices for lubricant applications. This is a better approach than "one oil fits all" approach.

Thus I usually buy Mobil 1 because I can get it at Costco, don't have to pay shipping and this makes it much cheaper.

Amsoil saved me from expensive engine repairs!

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!

Impressed !

I had heard about Amsoil and reviewed their data and wondered how much was real and how much is just advertising. 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 will always use AMSOIL in my vehicles.

AMSOIL makes oil changes well worth it. I know they upped their change intervals, but I still change my oil every 10k miles. When I do the oil change, it almost seems like I should be following their new interval suggestion. The oil after the amount of use is darker, but it's still very fluid and not thick like other oils I've used before AMSOIL. I use their filters along with the XL oil and it is the perfect combination. I thank AMSOIL for some of the best products.

Not so sure about this product?

I recently switched to this oil in my 4.6L f150. This truck has 106,100 miles on it. It's had motorcraft synthetic blend changed every 3k-5k miles with a fl-820 filter since new.
Immediately after switching to this oil the engine developed some cold start and low RPM knocking.
I believe this is due to the timing chain tensioners and or guides?
The tensioners rely on oil pressure to keep the chains tensioned.
So either the motorcraft was hiding a mechanical issue or this 5w20 isn't of similar viscosity to the motorcraft?
Oil sample will be sent to blackstone at 3k miles.
Still using the motorcraft fl-820 filter with this product.
I cannot recommend this product until I have more info.

I go out of my way for the best possible quality in the products I use to keep it looking good but also running even better. It's up in mileage so this is one reason why I switched to a full synthetic oil for the engine. I wasn't familiar with AMSoil but once I was introduced it's all i use now. But like I said earlier, I go out of my way to find the best quality for the price. I've been pleased with this oil more than any other I've used for the past 11 years.

Best oil on earth

This is the main body area. I'd much rather not receive these emails anymore. I've unsubscribed about 4 times now, but the emails just don't stop. I won't stop using Amsoil, but I mean, grow up.

Hemi oil I can trust

I use this oil in my Ram 1500 Hemi. Works as described.
Amsoil is the only oil I use in all gasoline and diesel engines I own. Not one oil related problem in 25 years. Not even an oil leak!

Getting My Friend to Switch to Amsoil

I finally talked my Friend into trying an oil Change to Amsoil. After changing he told me that his truck seemed to be running better, starting much easier, and he thought he was getting better milage. A few days later he told me that now he knew he was getting better milage, about 2mpg. His truck is an older Chevrolet half to 4wd extra cab. I personally was converted a few years ago but thats another story. We can call my friend Brent, He has been building hot rods and high performance motors for years. He wanted one grade higher in weight than was recommended for his truck because of the high miles but now thinks he would have been fine. He is converted and wants to get gear oil and atf so he can change all his fluids to Amsoil products. We will both be changing differentials and transfer case lubricants at the same time.

I have been aware of Amsoil since the late seventies. It is a superior product and the only synthetic I use.

Perfect for the HEMI!

The 5.7 sees some harsh use during the summer. Towing, extended idling time and dusty roads tend to abuse oil. The Amsoil stands up to the job. Because it is still under warranty I do not exceed the manufacturer recommended service intervals but lab tests show the oil can go well beyond that.

Xl 5w20 synthetic oil

I am on my second oil change with this product that replaced a factory synthetic blend. On initial start up there was a noticeable difference in how quiet engine noise was. Especially after several days not being started there was no "ticking" on start up with this product. Even after

No need for Signature Series oil...XL Works Great!

I find that the XL works great, and is not as expensive as the Signature Series. I change the oil every 6 months or 5-7000k miles regardless, so I see the XL as excellent for those of us who do regular fluid maintenance.

Running strong!

My truck (Dodge 03 1500) has 140000 on it. Amsoil has been there for me the whole time. Not one single issue. Runs like a champ. I run Amsoil in all my vehicles including my Harleys after initial break in period. I live in Tucson Arizona & Amsoil holds up great against the heat. Keeps everything running cooler. Oil is not all the same as many say it is. Big difference.

XL 5W-20 Synthetic Motor Oil

Outstanding product I change oil at 10,000 miles not the 3,000 dealer oil change (so they can get in your wallet more often). I have 200,000 miles on my truck and 130,000 on my Toyota Hylander and they use about 3/4 qt of synthetic oil between oil changes. I use the highest rated Amsoil oil and air filters with every oil change.

Best synthetic

I decided if I was to do extended oil changes for my vehicles that synthetic is the way to go. All my research says that XL is the best. My engine runs smooth, it starts easy in the middle of winter at -20 below. With a $30,000 vehicle why not take care of it with the best. As a preferred customer I think the price is reasonable.

Highly recommended

Use in my wife's daily driver-2010 sequoia- ran for 6400 miles on first change, drained and sent to Blackstone labs. Results were motor was good (like the last analysis stated) but the difference was even at 6400 miles of stop and go driving it still had 2.9 tbn's. They recommended 7500 and re-sample but I wouldn't be scared of 8000 mile drain intervals. Great great oil.

Best all around synthetic engine oil.

I have been using AMSOIL XL 5w20 synthetic engine oil, in my 2007 Dodge Ram 1500 with the 5.7L HEMI, for three years. I have engine conditions from long idle times to full out performance with my performance modified truck. I change my oil & oil filter every 5,000 miles, even though I think this oil would work all the way up to double mileage. The oil still looks very good at that mileage interval. I highly recommend the AMSOIL XL series, it cost less than the top grade synthetic engine oil, works very well in todays modern engines.
