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 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 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 Clutch Performance
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 is required.
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
