AMSOIL Synthetic Motorcycle Oils have been reformulated with new high performance additive technology that provides even greater multi-functional benefits for the special requirements of motorcycle applications. These independent and exclusive new AMSOIL formulations provide second-to-none viscosity protection for hot-running American and foreign motorcycle engines, transmissions and primary chaincases. Performance specifications include:API SG, SL/CF; JASO MA/MA-2; API GL-1
High Performance Lubricant for Engines and Transmissions
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 MA/MA2 as outlined
in JASO Standard T903: 2006.
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.
