Product Application Specs

XLM 5W-20 Synthetic Motor Oil

• API SN (Resource Conserving), SM
• ACEA A1/B1
• Ford WSS-M2C945-A, WSSM2C930-A
• Chrysler MS-6395
• 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.

SERVICE LIFE
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.

The only oil that I use

For over 12 years Amsoil is the only oil that I use for all of my cars. I can't really say if it has helped
my mileage but just from the comparison specks and the way my vehicles run is proof enough for me.
Better cold running, smoother idle, and longer change intervals are some of reasons the higher cost
is justified.

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.

Full syntetic motor oil.

I have a 2004 Mustang GT and have loved it since the day I got it way back in 2006. Because I plan to keep it, I try to keep it in top shape just like you would... and not cut corners. 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.

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.

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.
