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
requiring any of the following specifications:
API SH, SG, CF, 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
AMSOIL High Performance Synthetic Motorcycle Oils (AMF and AMV)
are formulated for extended drain intervals. Change AMF and AMV
at three times the engines manufacturer's recommended drain interval
or one year, 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. Non-AMSOIL oil filters should
be changed at the engine manufacturer's recommended filter change
interval.
RACING ENGINES
Change AMF and AMV at intervals specified by used oil analysis.
MARINE CRAFT AND OCCASIONALLY
USED GASOLINE ENGINES
AMSOIL High Performance Synthetic Motorcycle Oils are also ideal
for marine engines and all terrain vehicles (ATVs). Change AMV at
three times the engine manufacturer's recommended drain interval
or one year, whichever comes first.
FLEET MOTORCYCLES
Change AMF at three times the engine manufacturer's recommended
drain interval or six months, whichever comes first.
