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 photo 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,
helping improve clutch life. AMSOIL Synthetic 10W-40
Motorcycle Oil meets the wet clutch frictional requirements
of JASO Standard T903: 2006, MA/MA2 and ISO-L-EMA2 of ISO Standard 24254:2007.
For irrefutable proof of the superiority of AMSOIL Synthetic Motor Oils refer to the AMSOIL A Study of Motorcycle Oils white paper (G2156).
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®, Victory® and other motorcycles where
10W-40 or 20W-40 engine oils or SAE 80W/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 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.
