AMSOIL 20W-50 Synthetic Motorcycle Oil is a premium oil designed
for those who demand the absolute best lubrication for their motorcycles. AMSOIL
20W-50 Motorcycle Oil is the result of extensive research and is specially
formulated to excel in all areas unique to motorcycles, including the high
temperatures of air-cooled engines such as Harley-Davidson® V-Twins, wet-clutch
lubrication, extreme-pressure regions of gears and chains and rust common to
short trips and storage.
AMSOIL 20W-50 Synthetic Motorcycle Oil 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
Oil. It has exceptional high-temperature film strength and contains a heavy
treatment of anti-wear additives to reduce wear regardless of operating
conditions. AMSOIL 20W-50 Motorcycle Oil 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 Synthetic Motorcycle Oil, 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 20W-50 Motorcycle Oil performs like a gear
lube without the negative effects of extreme-pressure additives. In the FZG gear
test, AMSOIL achieved a perfect score with a “zero” wear rating (see test
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 Synthetic
Motorcycle Oil contains special anti-rust agents. It passes the ASTM D-1748
humidity cabinet rust test and clearly demonstrates superior rust protection.
Provides Excellent Wet Clutch Performance
AMSOIL 20W-50 Synthetic Motorcycle Oil contains no friction modifiers and
promotes smooth shifting and positive clutch engagement. It controls heat and
helps prevent slippage and glazing, while its high TBN helps to improve clutch
life by resisting the acids that can degrade clutch material.
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.
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.
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
Racing or modified engines are excluded from extended drain
interval recommendations. Oil changes are at the owner’s discretion.
