PRODUCT DESCRIPTION
AMSOIL Synthetic High Performance 20W-50 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 and is recommended for applications requiring the following
specifications:
API Service SJ, SH, SG, SF, CI-4, CH-4,
CG-4, CF-2, CF, CD, JASO MA
In general, Japanese motorcycles use 10W-40 (AMF) while US and European motorcycles use 20W-50 (AMV).
Check your owner's manual.
SERVICE LIFE
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.
RACING ENGINES
Change AMF and AMV at intervals specified
by used oil analysis.
