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
exceptional
high-temperature
film
strength
and
contains
a
heavy
treatment
of
anti-wear
additives
to
reduce
wear
regardless
of
the
operating
conditions.
AMSOIL
20W-50
Motorcycle
Oil
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.
