Product Details
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 to12,000-miles or one year, whichever comes first, between oil changes.
Product Description
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 293ºF (100º 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 (GMOD) Test
Protects Pistons from Low-Speed Pre-Ignition
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.

Reduces Maintenance
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 or one year4, if you choose, allowing you to change oil on your schedule, reduce maintenance, save money and reduce waste oil.

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" designation5 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.

Use AMSOIL XL Synthetic Motor Oil in applications that require any of the following specifications:

5W-20 (XLM)
API SN PLUS (Resource Conserving), SM…; GM dexos1 Gen 2 (supersedes 6094M); ACEA A1/B1; Ford WSS-M2C945-A, WSS-M2C930-A; Chrysler MS-6395; ILSAC GF-5, GF-4…; Fortified with detergents that exceed the dexos1 Gen 2 sulfated ash specification

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.

In gasoline-fueled vehicles, AMSOIL XL Synthetic Motor Oil is recommended for up to 12,000 miles/one year oil change intervals, or longer when recommended in owner's manuals or indicated by electronic oil life monitoring systems. Change the
oil filter at every oil change regardless of filter brand.

Technical Information
Extra Information
How does XL motor oil benefit the environment?
XL motor oil is better for the environment than traditional petroleum oils due to its superior additive construction and premium base oil chemistry. Its chemistry extends oil life, resulting in fewer oil changes, less waste oil and less packaging generated. By resisting volatility (burn‐off) and reducing wear, fewer emissions exit through the tailpipe and engines last longer. XL is also formulated with additive technology specifically designed to promote proper emission system operation and longevity.
What is the recommended drain interval for XL motor oil?
XL Synthetic Motor Oil is fortified with an "extended‐drain boost" to effectively achieve oil drain intervals of up to 12,000 miles/ one year or longer where recommended in owners' manuals or by oil life monitoring systems. XL's protects engines longer thanks to its unique additive technology, a high total base number (TBN) and strong base oil construction. Extensive testing proves its ability to maintain excellent protection and performance over long drain intervals.
