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
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 photos 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®,
Victory®, 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 for shaft drive hypoid gears or
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
For “on road” use in engines, transmissions and primary chaincases,
change AMSOIL MCV and AMSOIL engine oil filter at twice the motorcycle
manufacturer change interval or one year, whichever comes first. Change
other brand oil filters at standard intervals.
For “off road” use
in engines, transmissions and primary chaincases, change AMSOIL MCV at
the standard motorcycle manufacturer change interval.
For racing or in engines modified from the original factory
design, no change interval recommendation is made. Oil changes are at
the owner’s discretion.
