AMSOIL 20W-50 Synthetic Motorcycle Oil
(MCV) recommended for
Harley-Davidson, Buell, Victory, Ducati, BMW, Aprilla and Triumph
motorcycles calling for a 15W-50 or 20W-50 viscosity, providing superior
protection in engines, transmissions and primary chaincases.
AMSOIL 10W-40 Synthetic Motorcycle Oil
(MCF) is recommended for Honda,
Kawasaki, Yamaha, Suzuki, BMW, Husqvarna and KTM motorcycles calling for
a 10W-40 or 20W-40 viscosity, providing superior protection in engines
and transmissions.
Improved Transmission Protection
AMSOIL Synthetic Motorcycle Oils not only provide superior protection
for motorcycle engines, they also provide superior gear protection,
meeting API GL-1 gear lube viscosity requirements. AMSOIL Synthetic
10W-40 Motorcycle Oil (MCF) meets SAE 80W-90 gear lube requirements,
while AMSOIL Synthetic 20W-50 Motorcycle Oil (MCV) meets SAE 90 gear
lube viscosity requirements.
Viscosity is the most important characteristic of a lubricant.
Motorcycle gears create a shearing effect that causes permanent oil
viscosity loss. This thinning effect reduces the oil's ability to
prevent metal-to-metal contact and wear. The stability and natural
operating temperature ranges of the premium synthetic base stocks used
to formulate AMSOIL Synthetic Motorcycle Oils eliminate shear and reduce
wear. AMSOIL Synthetic Motorcycle Oils exhibit absolute shear stability
as measured by the Kurt Orbon shear stability test.
The high temperatures and tight tolerances common to motorcycle
applications also affect viscosity. The High Temperature/High Shear (HTHS)
Test (ASTM D-4683) measures a lubricant's viscosity under severe high
temperature and shear conditions. The more resistant an oil is to high
temperature viscosity loss, the better it protects, and even a HTHS
difference of 0.1 cP makes a significant difference.
AMSOIL Synthetic Motorcycle Oils exhibit higher HTHS viscosities than
competing conventional and synthetic motorcycle oils. As seen in the
graphs, AMSOIL Synthetic 20W-50 and 10W-40 Motorcycle Oils displayed the
highest High Temperature/High Shear viscosities in their respective test
groups, providing motorcycle engines and transmissions operating in the
harshest conditions with superior protection against wear and viscosity
loss and eliminating the need for separate gear case oils as recommended
by some competitors. Synthetic 10W-40 may also be used in two-cycle
transmissions.
Excellent Wet Clutch Performance
Many motorcycles utilize a clutch that is immersed in the motor oil. The
friction modifiers present in many automotive motor oils and the extreme
pressure additives present in EP gear lubricants produce a low
coefficient of friction between the clutch discs and plates, resulting
in clutch slippage and glazing. Slippage leads to increased operating
temperatures and reduced clutch life. AMSOIL Synthetic Motorcycle Oils
are formulated without friction modifiers, providing positive clutch
engagement, longer equipment life and reduced temperatures. AMSOIL
Synthetic Motorcycle Oils meet the clutch compatibility requirements
mandated by JASO MA.

Excellent Corrosion Protection
Most motorcycles spend the majority of their lives either parked or in
storage, but most motorcycle oils fail to address corrosion problems.
Corrosion protection during storage and in humid conditions is
essential to extending equipment life. AMSOIL Synthetic Motorcycle Oils
are formulated with specialized additive technology that not only
protect against corrosion and acids during operation, but also provide
exceptional protection during storage. The ASTM D-1748 Rust Test
measures a lubricant's ability to protect against rust and corrosion. A
standard metal reference coupon is immersed in the test oil before
being placed in a humidity cabinet for 24 hours at 120 degrees F. As
seen in the photos, the reference coupon treated with AMSOIL 20W-50
Synthetic Motorcycle Oil showed no signs of rust and corrosion, while
the competitor failed the test.

Outstanding Heat Resistance
Motorcycles operate in demanding, high heat conditions that require
robust high temperature deposit control additives. While many
conventional oils break down and oxidize when faced with high
temperatures, causing formation of carbon and sludge deposits, AMSOIL
Synthetic Motorcycle Oils effectively withstand oil break-down and
oxidation, keeping equipment running cooler and minimizing oil
consumption, thickening and emissions. Air-cooled engines get
especially hot while idling in traffic, commonly reaching temperatures
up to 240 degrees Fahrenheit. The extra margin of protection provided
by AMSOIL Synthetic Motorcycle Oils is especially important for hot
running air cooled motorcycle engines.
Foam Control
High engine
speeds and transmission gears in motorcycles churn the oil, suspending
air and causing foam. When this oil and air mixture is drawn into a
loaded area, the air compresses and decreases the thickness of the oil
film, compromising wear protection. In addition, suspended air promotes
oil oxidation, reducing its service life. AMSOIL Synthetic Motorcycle
Oils greatly reduce foaming to provide long term lubricating protection
in high speed, high RPM conditions.
Robust Additive Levels
Recent
automotive motor oil regulations have limited certain additive levels,
including the anti-wear additive known as ZDDP. ZDDP is an extremely
effective anti-wear, anti-oxidant additive, and reducing its level
results in compromised wear control and shortened service life. Because
motorcycle applications require robust additive systems to control wear
and oxidation, use of an automotive motor oil or an automotive motor
oil re-labeled as a motorcycle oil compromises protection and
performance. AMSOIL Synthetic Motorcycle Oils are overtreated with
robust additive packages, including high levels of calcium, phosphorus,
zinc and additional oxidation inhibitors, to extend oil life
expectancy, provide unmatched engine cleanliness and greatly reduce
wear.
AMSOIL Synthetic Motorcycle Oils are recommended for twice the
manufacturer's recommended drain interval for on-road motorcycles.
The Four Ball Wear Test (ASTM D-4172) determines the wear protection
properties of a lubricant. The smaller the average wear scar, the
better the wear protection provided by the lubricant. AMSOIL Synthetic
Motorcycle Oils produce significantly smaller wear scars than competing
motorcycle oils, providing unsurpassed protection against engine wear,
reducing maintenance costs and extending equipment life.
Cost Effective
AMSOIL Synthetic Motorcycle Oils provide excellent cost effectiveness and
are cost competitive with competing high end motorcycle oils. The unmatched
protection and performance provided by AMSOIL Synthetic Motorcycle Oils is
excellent insurance for today's expensive motorcycles and custom bikes.
