Winter Four-Stroke Performance

October 11th, 2010: Conventional oils thicken in the cold, which can result in inadequate lubrication to critical engine parts at cold start-up, or even prevent the engine from starting.

AMSOIL Formula 4-Stroke Power Sports Synthetic Motor Oil provides serious protection and performance in four-stroke engines, including ATV's and snowmobiles. Its broad OW-40 viscosity rating effectively protects in both hot and cold temperature extremes. AMSOIL Formula 4-Stroke Synthetic Small Engine Oil provides exceptional protection in the severe-service conditions common in both gasoline and diesel-fueled small engines, including welders, skidsteers, compressors, snowblowers and more. It remains fluid at sub-zero temperatures for superior cold-weather protection.

Winter Two-Stroke Performance

AMSOIL DOMINATOR and INTERCEPTOR Synthetic 2-Cycle Oils provide exceptional performance in snowmobiles and other two-stroke equipment. AMSOIL DOMINATOR is formulated with heavier base oils for "on the edge" operation, while also protecting pistons and bearings subjected to the rigors of extreme riding. AMSOIL INTERCEPTOR is engineered specifically for power sports applications and engines equipped with exhaust power valves. It contains the finest synthetic base oils and additives for exceptional cleanliness, while controlling exhaust valve sticking and providing outstanding overall lubrication.

Gasoline Additive

AMSOIL Quickshot SE is formulated to thoroughly clean varnish, gums and insoluble debris in two and four-stroke gasoline-powered small engines and power sports equipment fuel systems, restoring peak performance. It effectively addresses performance issues related to ethanol, water and dirty pump gas, while stabilizing fuel between uses and during short-term storage periods.

AMSOIL Reformulates its Line of XL Synthetic Motor Oils

AMSOIL Extended Life (XL) Synthetic Motor Oils have been reformulated to boast an extra measure of select additives that neutralize contaminants longer. Now featuring bolder packaging, XL Synthetic Motor Oils continue to provide significant benefits compared to conventional oils, including superior wear control, improved high and low temperature protection and increased fuel economy.

Meets or Exceeds New Motor Oil Specifications

Reformulated AMSOIL XL synthetic Motor Oils meet or exceed the new or exceed the new ILSAC GF-5 and API SN service requirements for motor oils used in gasoline-powered vehicles, and AMSOIL XL 5W-30 also carries the dexos1 applications recommendation (GM only grants dexos1 licenses to SAE 5W-30 products). They are API SN certified and bear the API donut on the label. API SN is the designation of the American Petroleum Institute and shares a number of criteria with ILSAC GF-5. The International Lubricant Standardization and Approval Committee (ILSAC) created ILSAC GF-5 primarily to address three important areas within the automotive industry: fuel economy, emissions system life and oil robustness.

Improved Fuel Economy

To achieve government-mandated fuel economy standards, OEMs are examining every engine component for potential efficiency gains, including motor oil. To meet the GF-5 specifications, motor oils must demonstrate an improvement in fuel economy compared to reference oil and retain at least part of that improvement after 100 hours of testing.

AMSOIL XL Synthetic Motor Oils are fuel-efficient formulations that reduce friction-related energy loss and meet the GF-5 specification. They provide better fuel economy compared to conventional, non-fuel-efficient motor oils.

Emissions System Improvements

Phosphorus is often used as an anti-wear agent in motor oils. Over time, however, it can volatize and enter after treatment devices such as catalytic converters and oxygen sensors, shortening their lifespan, increasing tailpipe emissions and causing increased engine oil oxidation and thickening.

AMSOIL XL Synthetic Motor Oils have excellent phosphorous retention and help improve catalytic converter service life for low exhaust emissions, in accordance with GF-5 requirements.

Engine Oil Robustness

For GF-5, engine oil robustness is defined as oil's performance in the areas of piston cleanliness, sludge resistance and turbo protection. Oils meeting GF-5 must exhibit improvements in each area relative to the previous GF-4 specification.

Fortified with extra detergent and dispersant additives, AMSOI XL Synthetic Motor Oils are engineered to resist sludge better than conventional oils, promoting clean operation for longer-lasting, better-running engines. As temperatures inside the combustion chambers of modern engines continue rising, piston cleanliness and turbo protection become more important. Deposits on the piston crown can cause pre-ignition, reducing performance, while sticking rings can cause blow-by, reduced compression and poor performance. Turbo charges can reach 100.000 rpm and temperatures of 1,200°F, creating an environmental that can destroy lesser oils, leading to thermal coking and bearing failure.

AMSOIL XL Synthetic Motor Oils resist the effects of thermal breakdown, including evaporation, viscosity loss and deposit formation for increased piston cleanliness and turbo protection.
