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 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 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.
