The big oil companies offer lots of slick fluffy marketing claims like "Nothing outperforms Mobil 1", but offer no proof or facts. The truth is, AMSOIL synthetic oil outperforms Mobil 1 and all other conventional and synthetic lubricants. And we have the proof to back it up. They don't, which is why they can only use slogans. AMSOIL, the First in Synthetics.

"Our Company makes the best lubricants in the world, period, and challenges anyone or any company to prove us wrong! That won't happen because our competitors know it's true." -A.J. Amatuzio, President & CEO.

PRODUCT DESCRIPTION

AMSOIL High Performance Synthetic 20W-50 Motor Oil is specifically formulated to provide tough lubricating protection in the most demanding operations.  It is recommended for use is motorcycles, pickup trucks, recreational vehicles and other high-stress vehicles powered by gasoline or diesel engines. AMSOIL SAE 20W-50 High Performance Synthetic Motor Oil may be used in all motorcycle engines, including those with a wet clutch system, requiring an API CD, SG-CG or SH-CD oil.

WEAR PROTECTION

The AMSOIL High Performance Synthetic 20W-50 Motor Oil anti-wear additive package contains high levels of zinc and phosphorous for superior protection of cam lobes and other high-pressure parts.  In fact, AMSOIL High Performance Synthetic 20W-50 Motor Oil contains more zinc and phosphorous than most popular motorcycle manufacturer motor oils.  Its superior anti-wear package offers superior wear protection.  AMSOIL High Performance Synthetic 20W-50 Motor Oil leaves a wear scar up to 40 percent smaller than the scars left by other popular brands in the ASTM D4172 Four-Ball Wear Test.

Some motorcycle transmissions and engines share an oil sump, so the engine oil also provides wear protection to the transmission gears.  AMSOIL High Performance Synthetic 20W-50 Motor Oil offers superior wear protection to transmission gears, which are often subjected to high surface pressure and rotation speed.  It also promotes proper wet clutch performance.

FRICTION MODIFIER FREE

AMSOIL High Performance Synthetic 20W-50 Motor Oil contains no friction modifiers.  The friction modifier free formulation of AMSOIL High Performance Synthetic 20W-50 Motor Oil ensures dependable starting, smooth running, good fuel efficiency, desirable stall speeds and clutch compatibility.

DIESEL FORMULATED

AMSOIL High Performance Synthetic 20W-50 Motor Oil contains a robust dispersant/detergent additive package, making it ideal for use in high-stress diesel engines.  Its 12+ TBN ensures lasting protection against acid and soot in high-stress diesel applications.  In fact, its dispersant/detergent additive package is a proven extended drain lubricant.

TEMPERATURE AND PERFORMANCE

AMSOIL High Performance Synthetic 20W-50 Motor Oil offers the superior protection and lubrication at high and low temperatures found only in top-quality synthetic oils.  Its outstanding low temperature fluidity ensures easy cranking, dependable starting and fast post-startup protection.  Its superior high-temperature protection ensures the formation of a clean, protective film of oil between working parts during high-temperature, high-stress operations.

High-temperature operations often lead to the thermal degradation and oxidation of conventional oils, which leads to the formation of deposits, sludge and varnish.  AMSOIL High Performance Synthetic 20W-50 Motor Oil withstands thermal degradation and oxidation at higher temperatures than conventional oils do, ensuring clean, dependable performance in high-stress, high temperature operations.  

SERVICE LIFE

AMSOIL High Performance Synthetic 20W-50 Motor Oil (ARO) is formulated for extended drain intervals.  Length of service depends on application.

PERSONAL VEHICLES WITH NON-TURBOCHARGED GASOLINE ENGINES

Change ARO at three times the engine manufacturer's recommended drain interval or one year, whichever comes first.

VEHICLES WITH TURBOCHARGED GASOLINE ENGINES

Change ARO at two times the engine manufacturer's recommended drain interval or six months, whichever comes first.

RACING ENGINES

Change ARO at intervals specified by used oil analysis.

VEHICLES WITH LIGHT-DUTY AND NON-TURBOCHARGED DIESEL ENGINES

Change ARO at two or more times the engine manufacturer's recommended drain interval if the findings of used oil analysis support those drain intervals or six months, whichever comes first.

HEAVY DUTY AND TURBOCHARGED DIESEL ENGINES

Change ARO at two or more times the engine manufacturer's recommended drain interval if the findings of used oil analysis support those drain intervals or six months, whichever comes first.

MOTORCYCLES, ALL-TERRAIN VEHICLES, ETC.

Change ARO at two times the engine manufacturer's recommended drain interval or six months, whichever comes first.

MARINE CRAFT AND OCCASIONALLY USED GASOLINE ENGINES

Change ARO at three times the engine manufacturer's recommended drain interval or six months, whichever comes first.

FLEET VEHICLES AND INDUSTRIAL GASOLINE ENGINES

Change ARO at two times the engine manufacturer's recommended drain interval or six months, whichever comes first.

If a vehicle is equipped with an AMSOIL Oil Filter, the filter should be changed at 12,500-mile or six-month intervals (whichever comes first) in gasoline engines and 7,000-mile or six-month intervals (whichever comes first) in diesel engines.  Non-AMSOIL oil filters should be changed at the engine manufacturer's recommended filter change interval.
