Use AMSOIL XL Synthetic Motor Oil in applications that require any of the following specifications:
Product Application Specs
XLO 10W-40 Synthetic Motor Oil
• API SP, SN PLUS, SM
• ACEA A3/B3, A3/B4
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.
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.

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.
For immediate answers to your technical questions call (715) 399-TECH (8324) between 8 a.m. and 5 p.m. Central time or email firstname.lastname@example.org.
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.
