PRODUCT DESCRIPTION
AMSOIL Synthetic 10W-40
Motorcycle Oil (MCF) is
a premium oil designed
for those who demand the
absolute best
lubrication for their
motorcycles. AMSOIL MCF
is the
result of extensive
research, and it is
specially formulated to
excel in all areas
unique to motorcycles,
including high engine
RPM, wet clutch
lubrication, extreme
pressure regions of
gears and rust common to
short drives and
storage.
AMSOIL MCF 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 at right).
AMSOIL MCF 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 MCF, there is no
need for separate
transmission lubricants. It
is absolutely shear stable
and will not thin out from
mechanical activity. AMSOIL
MCF performs like a gear
lube without the negative
effects of extreme pressure
additives. In the FZG gear
test, AMSOIL MCF 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
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 MCF
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 MCF contains no
friction modifiers and
promotes smooth shifting and
positive clutch engagement.
AMSOIL MCF 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 10W-40
Motorcycle Oil is
recommended for liquid or
air-cooled 4-stroke engines.
It meets SAE 80W/90, API
GL-1 gear oil requirements
and is recommended for
transmissions on both 4- and
2-stroke motorcycles. AMSOIL
MCF is recommended for
Honda®, Kawasaki®, Yamaha®,
Suzuki®, BMW®, Husqvarna®,
KTM® and other motorcycles
where 10W-40 or 20W-40
engine oils or SAE 80W/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 10W-40
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
and transmissions, change
AMSOIL MCF 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 and
transmissions, change AMSOIL
MCF 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.
