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. 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 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.
