AMSOIL 10W-30 Synthetic Motorcycle Oil is a premium oil designed for
those who demand the absolute best lubrication for their motorcycles.
It 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 10W-30 Synthetic Motorcycle Oil
is multi-functional and fulfills the requirements of both domestic and
foreign motorcycles. It outperforms other conventional and synthetic
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
Reduces Friction, Heat and Wear
In high heat conditions, engine protection is not sacrificed with AMSOIL 10W-30
Synthetic Motorcycle Oil. It exceeds the standard for high-temperature film strength
(see graph at right) to deliver excellent wear protection. It 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. AMSOIL 10W-30
Synthetic Motorcycle Oil is thermally (heat) stable and contains maximum levels of
oxidation inhibitor additives. It is extremely resistant to volatility and is engineered to
prevent damaging sludge and carbon deposits for superior engine cleanliness.
Provides Extreme Pressure Quality
Protection for Gears
With AMSOIL 10W-30 Synthetic Motorcycle Oil, there is no need for separate
transmission lubricants. It is shear stable and will not thin out from mechanical activity.
It 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 10W-30 Synthetic Motorcycle Oil contains special anti-rust
agents that deliver superior rust protection. With its high 11.1 total base number (TBN),
10W-30 Synthetic Motorcycle Oil provides greater protection from acid corrosion and
helps maintain internal engine cleanliness.
Provides Excellent Wet
AMSOIL 10W-30 Synthetic Motorcycle Oil contains no friction modifiers and
promotes smooth shifting and positive clutch engagement. It is engineered to control
heat and prevent slippage and glazing, promoting longer clutch life.
AMSOIL 10W-30 Synthetic Motorcycle Oil is recommended for
liquid- or air-cooled four-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 two- and four-stroke motorcycles. AMSOIL 10W-30 Synthetic
Motorcycle Oil 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
AMSOIL 10W-30 Synthetic Motorcycle Oil is compatible with
conventional and synthetic motor oils; however, mixing oils may
shorten the oil’s life expectancy and reduce its 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.
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® Motorcycle Oil Filter, change the filter
at standard intervals. For off-road use, change AMSOIL 10W-30
Synthetic Motorcycle Oil at motorcycle manufacturer intervals.
Racing or modified engines are excluded from extended
drain interval recommendations; oil changes are at the owner’s
