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 oil.
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.
