Protect Your Engine With AMSOIL Synthetic Motor Oils
Motor Oils That Are Designed – Not Refined

Get Top Performance, Protection and Extended Drain Intervals from Virtually Any 4-cycle Engine

Amzoil-canAzo-SigWhen the first can of AMSOIL 10W-40 appeared on the market in 1972, it signaled the birth of an entire industry. AMSOIL synthetic lubricants have expanded the boundaries of lubrication science and redefined the performance possibilities of modern machinery and engines.

AMSOIL will save you money and give you the protection and peace of mind that comes from using the best. Today’s engines produce more power from a smaller plant with a smaller radiator and a smaller volume of oil to cool and lubricate them. They need more protection from heat than conventional oils give them. Conventional oils keep engines from failing most of the time, but there’s a big difference between marginal failure prevention and the total wear protection that AMSOIL delivers!

AMSOIL eliminates friction and wear

AMSOIL Virtually Eliminates Friction and Wear

**To develop a way to clearly establish AMSOIL Synthetic Motor Oil as the top choice for superior wear protection, AMSOIL Signature Series 5W-30 Synthetic Motor Oil was subjected to the 100-hour Sequence IIIG Engine Test (ASTM D 7320), an industry-standard test designed to evaluate motor oil in several key performance areas. It must be passed to meet the API SN and ILSAC GF-5 motor oil specifications. The laboratory that performed the test was instructed to DOUBLE the test to 200 hours. Signature Series not only passed the double-length test, it did so with flying colors. See complete results in the Double-Length Sequence IIIG Engine Test Study listed above, or click here.

XL Series 100% Synthetic Motor Oils

AMSOIL XL Series 100% Synthetic Motor Oils

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 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.

 

  • 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

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.

Formula 4-Stroke® Synthetic Motor Oils

Four-stroke gasoline engines have long been a mainstay of the general marine industry. They have succeeded in reducing emissions and increasing fuel efficiency, and they have also been a hit with consumers. When four-NMMA Approved FC-W Catalyst Compatiblestroke outboard motors were introduced to the market, manufacturers recommended either their own specially formulated oil or an API SG or SL automotive oil. However, because the specific lubrication requirements of automobiles and outboard motors are different, it soon became apparent that four-stroke outboard motors would require their own oil specification. This standard, entitled FC-W, was released by the National Marine Manufacturers Association (NMMA) in August 2004.

AMSOIL Synthetic Marine Engine Oils are certified by the National Marine Manufacturers Association (NMMA) for use in four-stroke outboard motors. They are also designed for use in 4-stroke marine inboard engines, and excellent for personal watercraft.

These high-quality oils demonstrate outstanding performance and meet the NMMA FC-W Catalyst Compatible specification requirements:
