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.
See
specific service life notes
for Harley Davidson
Motorcycles
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.
