Product Code: AMF | 10W40 HIGH PERFORMANCE |
AMSOIL Synthetic High Performance 10w40 Motorcycle Engine Oil is specially formulated to provide tough lubricating protection in the most demanding operations. It is recommended for use in all four-cycle motorcycle and ATV engines, including those with wet clutch systems requiring API CD, SG-CG or SH-CD oils.
WEAR PROTECTION
AMSOIL Synthetic Motorcycle Oils are specially formulated with high levels of zinc and phosphorous for superior protection of cam lobes and other high pressure components. In fact, AMSOIL Synthetic Motorcycle Oils contain more zinc and phosphorous than other popular motorcycle oils (see graph). AMSOIL Synthetic Motorcycle Oils leave a wear scar up to 40 percent smaller than the scars left by other popular brands in the ATM D4172 Four-Ball Wear Test.
Some motorcycle and ATV transmissions and engines share an oil sump, so the engine oil also provides wear protection to the transmission gears. AMSOIL offers superior wear protection to transmission gears, which are often subject to high surface pressure and rotation speed. It also promotes proper wet clutch performance.
FRICTION MODIFIER FREE
AMSOIL Synthetic Motorcycle Oils contain no friction modifiers, making them ideal for motorcycle and ATV engines. The friction modifier free formulation of AMSOIL ensures dependable starting, smooth running, good fuel efficiency, desirable stall speeds and clutch compatibility.
PERFORMANCE FORMULATED
AMSOIL Synthetic Motorcycle Oils contain a robust dispersant/detergent package, making them ideal for use in high-stress motorcycle engines. The dispersant/detergent additive packages allow them to stay serviceable longer than other oils.
TEMPERATURE AND PERFORMANCE
AMSOIL High Performance Synthetic Motorcycle Oils provide superior performance. Their outstanding low temperature fluidity ensures easy cranking, dependable starting and fast post-startup protection. The 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 withstands thermal degradation and oxidation at higher temperatures than conventional oils do, ensuring clean, dependable performance in high-stress, high-temperature operations. Especially in air-cooled engines.
APPLICATIONS
AMSOIL High Performance Synthetic Motorcycle Oils may be used in all four-cycle air- and liquid-cooled gasoline motorcycle engines requiring any of the following specifications:
API SJ, SH, SG, SF, CI-4, CH-4, CG-4, CF-2, CF, CD, JASO MA
In general, Japanese motorcycles use 10w40 (AMF) while US and European motorcycles use 20w50 (AMV). Check your owner's manual.
Change AMSOIL High Performance Synthetic Motorcycle Oil according to manufacturer's recommendations, without oil filtration. With oil filtration (AMSOIL SDF Filter), up to 2 times longer than manufacturer's recommendations or 6 months, whichever comes first. If a Hastings or other filter is used, filter should be changed at manufacturer's recommendations.
Change AMF and AMV at intervals specified by used oil analysis.
