PRODUCT DESCRIPTION
AMSOIL Synthetic 10W-30 Motorcycle Oil (MCT) is a premium oil
designed for those who demand the absolute best lubrication for
their motorcycles. AMSOIL MCT is the result of extensive
research, and it is specially formulated to excel in all areas
unique to motorcycles, including high engine RPM, wet clutch
lubrication, extreme pressure regions of gears and rust common
to short drives and storage.
AMSOIL MCT is multi-functional and fulfills the requirements
of both domestic and foreign motorcycles. It outperforms other
conventional and synthetic motorcycle oils.
AMSOIL, the leader in automotive synthetic lubrication,
produced the world’s first API-qualified synthetic motor oil in
1972. Trust the extensive experience of AMSOIL The First in
Synthetics® to do the best job protecting your engine.
Reduces Friction, Heat and Wear
In high heat conditions, engine protection is not sacrificed
with AMSOIL Synthetic Motorcycle Oil. AMSOIL 10W-30 keeps
engines running cool by effectively reducing friction and heat,
and it contains a heavy treatment of anti-wear additives to
reduce wear regardless of the operating conditions (see
Four-Ball Wear Test graph below). AMSOIL MCT is thermally
(heat) stable and contains maximum levels of oxidation
inhibitor additives. It is extremely resistant to volatility
(see NOACK Volatility graph on reverse) and engineered to
prevent damaging sludge and carbon deposits for superior engine
cleanliness.

Provides Extreme Pressure Quality Protection for
Gears
With AMSOIL MCT, there is no need for separate transmission
lubricants. It is shear stable and will not thin out from
mechanical activity. AMSOIL MCT performs like a gear lube
without the negative effects of extreme pressure additives,
such as poor wet-clutch performance.
Delivers Superior Rust and Corrosion
Protection
Motorcycles are prone to rust from storage, humidity and short
drives. Rust can cause major damage such as uncontrolled wear,
compression loss and blow-by. Good rust protection, however,
comes by design and is not natural to engine oils. Unlike many
motorcycle oils, AMSOIL MCT contains special anti-rust agents
that deliver superior rust protection. With its high TBN (see
TBN graph on reverse), AMSOIL 10W-30 provides greater
protection from acid corrosion and helps maintain internal
engine cleanliness.
Provides Excellent Wet Clutch
Performance
AMSOIL Synthetic 10W-30 Motorcycle Oil contains no friction
modifiers and promotes smooth shifting and positive clutch
engagement. It controls heat and prevents slippage and glazing,
promoting longer clutch life.


APPLICATIONS
AMSOIL Synthetic 10W-30 Motorcycle Oil is recommended for
liquid- or air-cooled 4-stroke motorcycles, scooters, ATVs and
UTVs requiring an SAE 10W-30 fluid. It meets SAE 80, API GL-1
gear oil requirements and is recommended for transmissions on
both 4- and 2-
stroke motorcycles. AMSOIL MCT is recommended for Honda®,
Yamaha®, Suzuki® and Kawasaki® motorcycles and scooters, as
well as Arctic Cat®, Can-Am®, Honda®, Kawasaki® and Suzuki®
ATVs and UTVs. Not recommended where an API GL-4 or GL-5 gear
oil is required.
MIXING AMSOIL
AMSOIL Synthetic 10W-30 Motorcycle Oil is compatible with
conventional and synthetic motor oils; however, mixing oils may
shorten the oil life expectancy and reduce the performance
benefits. AMSOIL does not support extended drain intervals
where oils have been mixed.
Aftermarket oil additives are not recommended for use with
AMSOIL motorcycle oil.
SERVICE LIFE
Recommended for use up to twice the motorcycle manufacturer
change interval (miles/hours) or one year, whichever comes
first, in engines and transmissions. When using an engine
filter other than AMSOIL Ea, change the filter at standard
intervals.
For “off road” use, change AMSOIL MCT at motorcycle
manufacturer intervals.
Racing or modified engines are excluded from extended drain
interval recommendations. Oil changes
are at the owner's discretion.
