XL Synthetic Motor Oil: Stronger for Longer

The new XL Synthetic Motor Oil formulation delivers more cleaning power, complete protection against oil breakdown and new extended-drain recommendations.

XL Synthetic Motor Oil (XLZ, XLM, XLF, XLT, XLO)

XL Synthetic Motor Oil features a boosted formulation that delivers more cleaning power and promotes longer engine life. It’s engineered for advanced automotive technology, including turbochargers and direct injection. XL is the perfect choice for enthusiasts who want to do something extra for their vehicles. The new formulation will become available in October or when current inventory is depleted.

  • 25 percent more cleaning power1
  • Achieved 100 percent protection against LSPI2
  • Extra protection that lasts up to 12,000 miles or 1 year, whichever comes first
  • API-licensed to meet the requirements commonly found in owner’s manuals

Fights Breakdown

XL Synthetic Motor Oil maintains its fluidity (viscosity) under the most extreme conditions. Some oils break down after extended periods of high- or low-temperature operation. These viscosity changes can lead to numerous issues:

  • Excessive oil consumption
  • Engine deposits
  • Accelerated wear
  • Difficult cold starts

The GM Oxidation and Deposit (GMOD) engine test simulates severe operating conditions to assess a motor oil’s 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 breakdown, ensuring protection in extreme temperatures.3

XL = Extended Life

AMSOIL XL Synthetic Motor Oil now provides even longer-lasting engine protection. Drain intervals can now be extended up to 12,000 miles, one year or longer when recommended in owner’s manuals or indicated by electronic oil life monitoring systems. This recommendation extends to aftermarket, original equipment manufacturer (OEM) or AMSOIL Ea® Oil Filters as well – simply replace the filter at every oil change.

Protects Pistons from Low-Speed Pre-Ignition

Like Signature Series and OE, XL features an advanced detergent system to protect vital engine parts like pistons and connecting rods. Most new engines feature gasoline direct-injection (GDI), often combined with a turbocharger to boost power and improve fuel economy. These new technologies pose significant challenges to motor oil, one of which is low-speed pre-ignition (LSPI). LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. It occurs in today’s advanced engines and is much more destructive than typical pre-ignition.

OEMs like GM* have addressed the issue by designing tests to determine a motor oil’s ability to prevent LSPI. The GM test allows up to five LSPI events to receive a passing score. XL Synthetic Motor Oil provided 100 percent protection against LSPI2 – zero occurrences were recorded.
