Harley-Davidson/AMSOIL Oil Chart
AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil is a premium oil designed
for those who demand the absolute best lubrication for their motorcycles.
It 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 Synthetic V-Twin Motorcycle Oil is multi-functional
and fulfills the requirements of both domestic and foreign motorcycles.
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 Wear and Deposits
AMSOIL Synthetic V-Twin Motorcycle Oil
contains a heavy treatment of anti-wear
additives to reduce wear regardless of
the operating conditions. It is thermally
(heat) stable and contains maximum
levels of oxidation inhibitor additives.
After 250 hours (13,647 miles) on an
engine dyno, AMSOIL Synthetic V-Twin
Motorcycle Oil eliminated piston scuffing and wear for long engine life and
maximum power (see image).
Withstands Extreme Heat
Big, powerful V-twin engines run
extremely hot, especially in summer
during stop-and-go rally or parade traffic. High heat breaks down oil
formulated for standard service,
inviting wear and performance-robbing
deposits. AMSOIL Synthetic V-Twin Motorcycle Oil is formulated with
naturally heat-resistant synthetic base
oils that resist oxidation in extreme heat.
Its unique additive system helps keep engines clean and running efficiently in
the toughest riding conditions.
Extreme-Pressure Protection for
Gears and Chains
AMSOIL Synthetic V-Twin Motorcycle
Oil delivers exceptional protection in
transmissions and primary chaincases.
It is absolutely shear stable and will
not thin out from mechanical activity.
AMSOIL 20W-50 V-Twin 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.
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, wear, compression
loss and blow-by. Good rust protection,
however, comes by design and is
not natural to motor oils. Unlike many
motorcycle oils, AMSOIL Synthetic
Motorcycle Oil contains special antirust
agents. It passes the ASTM D1748
humidity cabinet rust test, demonstrating
superior rust protection to help your
engine achieve maximum performance
and long life.
- Resists extreme heat
- Retains viscosity for excellent
wear protection
- Convenience of one lubricant
for all three sumps
Provides Excellent Wet-Clutch Performance
AMSOIL 20W-50 Synthetic V-Twin 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 improve clutch life by
resisting the acids that can degrade clutch material.
APPLICATIONS
Use in motorcycles that require 15W-50 or 20W-50 motorcycle oil and any of the specifications listed below, including those
made by Harley-Davidson*, Buell*, Ducati*, Aprilia*, BMW* and
Triumph*.
JASO MA/MA-2 • API SG/SL/CF/CG-4 • ISO-L-EMA2
Do not use where an API GL-4 or GL-5 gear oil is required.
COMPATIBILITY
AMSOIL 20W-50 Synthetic V-Twin Motorcycle Oil is compatible with
other synthetic and conventional motor oils. Mixing AMSOIL oils
with other oils, however, will shorten the oil’s life expectancy and
reduce its performance benefits. AMSOIL does not support
extended drain intervals where oils have been mixed.
Aftermarket oil
additives are not recommended for use with AMSOIL Synthetic Motorcycle Oils.
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 20W-50 Synthetic V-Twin Motorcycle Oil at motorcycle manufacturer-recommended intervals.
Racing or modified engines are excluded from extended
drain interval recommendations. Oil changes are at the
owner's discretion.
