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.
