 High
Performance 10W-40 Synthetic Motorcycle Engine Oil
AMSOIL Synthetic High Performance
10W-40 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.
(see below)
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, 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.
