AMSOIL Recommended Oils For Harley Davidson Motorcycles
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 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 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
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 photos 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®, Victory®, 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 for shaft drive hypoid gears or 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
For “on road” use in engines, transmissions and primary chaincases,
change AMSOIL MCV 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, transmissions and primary chaincases, change AMSOIL MCV 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.
