High Performance Lubricant for Engines, Transmissions and Primary Chaincases
API SG, SL/CF; JASO MA/MA2; API GL-1
PRODUCT DESCRIPTION
AMSOIL Synthetic 20W-50 Motorcycle Oil (MCV) is
a premium oil designed for those who demand the absolute best lubrication for
their motorcycles. AMSOIL MCV is the result of extensive research, and it is
specially formulated to excel in all areas unique to motorcycles, including
high temperatures of air-cooled engines such as Harley Davidson® V-Twin,
wet clutch lubrication, extreme pressure regions of gears and chains and rust
common to short trips and storage.
AMSOIL MCV 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 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 motorcycle.
Reduces Friction, Heat and Wear
In high heat conditions, engine protection is not sacrificed with AMSOIL Synthetic
Motorcycle Oil. It has the best high temperature film strength (see High
Temperature Viscosity Protection graph below) of all oils tested and contains
a heavy treatment of anti-wear additives to reduce wear regardless of the
operating conditions (see Wear Comparison graph on reverse). AMSOIL MCV
is thermally (heat) stable and contains maximum levels of oxidation inhibitor
additives. It is extremely resistant to breakdown and engineered to prevent
damaging sludge and carbon deposits for superior engine cleanliness.

Provides Extreme Pressure Quality Protection
for Gears and Chains
With AMSOIL MCV, there is no need for separate transmission or primary chaincase
lubricants. It is absolutely shear stable and will not thin out from mechanical
activity. AMSOIL MCV performs like a gear lube without the negative effects
of extreme pressure additives. In the FZG gear test, AMSOIL MCV achieved a
perfect score with a “zero” wear rating (see photo below).

Delivers
Superior Rust Protection
Motorcycles are prone to rust from storage, humidity and short drives. Rust
can cause major damage such as roller bearing failure, 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 MCV contains special
anti-rust agents. It passes the ASTM D-1748 humidity cabinet rust test and
clearly demonstrates superior rust protection (see photos below).

Provides Excellent
Wet Clutch Performance
AMSOIL MCV contains no friction modifiers and promotes smooth shifting and
positive clutch engagement. AMSOIL MCV controls heat and prevents slippage
and glazing, and its high TBN resists acids that can degrade clutch material,
helping improve clutch life.
APPLICATIONS
AMSOIL Synthetic 20W-50 Motorcycle Oil is recommended for air or liquid cooled
4-stroke engines. It meets SAE 90, API GL-1 gear oil requirements and is
recommended for transmissions and primary chaincases. AMSOIL MCV is recommended
for Harley Davidson®, Buell®, KTM, Ducati®, Aprilia®, BMW®,
Triumph® and other motorcycles where 15W-50 or 20W-50 engine oils or
SAE 90, GL-1 gear oils are used. Not recommended where an API GL-4 or GL-5
gear oil is required.
MIXING AMSOIL
AMSOIL Synthetic 20W-50 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, transmissions
and primary chaincases. For Big Twin Harley-Davidson transmissions only,
follow the Harley-Davidson recommended drain interval for synthetic oil
of up to 20,000 miles or one year, whichever comes first. When using an
engine filter other than AMSOIL Ea, change the filter at standard intervals.
For “off-road” use,
change AMSOIL MCV at motorcycle manufacturer
intervals.
Racing or modified
engines are excluded from extended drain
interval recommendations. Oil changes are
at the owner’s discretion.
