AMSOIL High Performance Synthetic 10W-40 Motor Oil may be
used in gasoline or
diesel engines requiring oils meeting the following specifications:
AMSOIL High Performance Synthetic 10W-40 Motor Oil is
specially formulated
to provide tough lubricating protection in the most demanding operations. It is
recommended for use in motorcycles, pickup trucks, recreational vehicles and
other high-stress vehicles powered by gasoline or diesel engines.
AMSOIL High Performance Synthetic 10W-40 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.
The AMSOIL High Performance Synthetic 10W-40 Motor Oil
anti-wear additive
package contains high levels of zinc and phosphorus for superior protection of
cam lobes and other high-pressure parts. In fact, AMSOIL High Performance
Synthetic 10W-40 Motor Oil contains more zinc and phos-phorus than most popular motorcycle
manufacturer motor oils (see graph at right). Its superior anti-wear
package offers superior wear protection. AMSOIL High Performance Synthetic
10W-40 Motor Oil leaves a wear scar up to 38 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 10W-40 Motor Oil 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.
AMSOIL High Performance Synthetic 10W-40 Motor Oil contains
no friction
modifiers, making it ideal for motorcycle engines. The friction modifier free formul-
ation of AMSOIL High Performance Synthetic 10W-40 Motor Oil ensures dependable starting,
smooth running, good fuel efficiency, desirable stall speeds and clutch compatibility.
AMSOIL High Performance Synthetic 10W-40 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.
AMSOIL High Performance Synthetic 10W-40 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 10W-40 Motor Oil withstands thermal degradation and oxidation
at higher temperatures than conventional oils do, ensuring clean, dependable performance
in high-stress, high-temperature operations.

AMSOIL High Performance Synthetic 10W-40 Motor Oil will not
void new vehicle warranties.
New vehicle warranties are premised on the use of oils meeting specific API service
classifications and
SAE viscosity grades. AMSOIL High Performance Synthetic 10W-40 Motor Oil meets the current
API and SAE requirements (as labeled) and is perfectly suited for use in any new vehicle
stipulating those requirements.
AMSOIL High Performance 10W-40 Synthetic Motor Oil (AMO) is formulated for extended drain intervals. Length of service depends on application.
Change AMO at 25,000-mile or one year intervals, whichever comes first.
Change AMO at three times the engine manufacturer's
recommended drain interval
or six months, whichever comes first.
Change AMO at intervals specified by used oil analysis.
Change AMO 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.
Change AMO at two times or more the engine manufacturer's
recommended drain interval if the findings of
used oil analysis support those drain intervals or six months, whichever comes first.
Change AMO at three times the engine manufacturer's
recommended drain interval
or one year, whichever comes first.
Change AMO at three times the engine manufacturer's
recommended drain interval
or one year, whichever comes first.
Change AMO at three times the engine manufacturer's
recommended drain interval
