PRODUCT
DESCRIPTION
AMSOIL Synthetic Super Heavy Weight
Racing Oil (AHR) is a high-viscosity
oil designed for high-horsepower racing
engines, typically supercharged and
alcohol-burning or nitro-fueled,
requiring a high-viscosity oil to
resist the thinning effects of fuel
dilution.
AMSOIL Synthetic Super Heavy
Weight Racing Oil is formulated
specifically for wear protection and
friction reduction in the extreme
conditions of racing. It is race proven
and reduces friction, promotes power
and inhibits wear.
Motorcycle
Applications
AMSOIL Synthetic Super Heavy Weight
Racing Oil is formulated with a
complete and robust additive package,
making it suitable for all engines for
which API SL/CF SAE 60 oils are
specified or desired. AMSOIL Synthetic
Super Heavy Weight Racing Oil contains
no friction modifiers and is wet-clutch
compatible, meeting the frictional
requirements of JASO MA and ISO-L-EMA.
The combination of high viscosity, full
additive system and wet-clutch
compatibility make this oil an
excellent candidate for use in
air-cooled vintage and classic
motorcycle engines such as the
Harley-Davidson Knucklehead and
Shovelhead models.
Heat
Stability
AMSOIL Synthetic Super Heavy Weight
Racing Oil is highly resistant to
thermal degradation and oxidation. Even
in long-term, high-temperature service,
AMSOIL Synthetic Super Heavy Weight
Racing Oil maintains its specified
chemical and physical properties,
forming no sludge, varnish, deposits or
acids and maintaining its specified
viscosity and ability to protect and
lubricate engines.
Oil
Consumption
AMSOIL Synthetic Super Heavy Weight
Racing Oil is highly resistant to
evaporative losses, which keeps oil
consumption rates low. Low rates of oil
consumption allow oil to flow freely
without significant “boiloff”
thickening to ensure dependable engine
lubrication and protection.
Corrosion, Rust and
Foam Control
AMSOIL Synthetic Super Heavy Weight
Racing Oil seals out rust, neutralizes
acids and resists foaming. Rust
inhibition is especially important for
engines subject to frequent short-trip
operations or frequent periods of
storage. Acid neutralization protects
engines from damage caused by corrosive
by-products of combustion. Foam
resistance ensures protection against
the metal-to-metal contact and wear
that occurs when air is trapped in an
oil.
Viscosity
Retention
AMSOIL Synthetic Super Heavy Weight
Racing Oil is shear stable, so the
viscosity grade that’s installed in the
engine is the viscosity grade that
stays in the engine. That’s especially
important for race engines, motorcycle
engines and other engines subject to
high-temperature/high-stress
operations. Viscosity retention ensures
the maintenance of a protective
lubricant film between working metal
parts, which prevents metal-to-metal
contact and consequent failure or
wear.
APPLICATIONS
AND RECOMMENDATIONS
AMSOIL Synthetic Super Heavy Weight
Racing Oil is recommended for use in
gasoline- or alcohol-fueled engines
requiring and SAE 60, API SL/CF engine
oil. Also recommended for motorcycle
engines requiring an SAE 60 JASO MA or
ISO-L-EMA fluid.
AMSOIL Synthetic Super
Heavy Weight Racing Oil is not
recommended for use in
cold-temperature environments.
MIXING
AMSOIL
AMSOIL Synthetic Super Heavy Weight
Racing Oil is compatible with
conventional and synthetic motor oils.
Mixing AMSOIL motor oils with other
oils, however, will shorten the oil
life expectancy and reduce the
performance benefits. Aftermarket oil
additives are not recommended for use
with AMSOIL motor oils.
