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. Its race-proven formulation is designed specifically to reduce friction, inhibit wear and promote power in extreme racing conditions.

Excellent Heat Stability
Synthetic Super Heavy Weight Racing Oil is highly resistant to thermal degradation and oxidation. Even in long-term, high-temperature service, it maintains viscosity and resists the formation of sludge, varnish, deposits or acids for continued wear protection.

Reduced Oil Consumption
By resisting evaporation, Synthetic Super Heavy Weight Racing Oil reduces oil consumption and inhibits thickening, allowing the oil to flow freely for dependable engine lubrication and protection.

Inhibits Corrosion, Rust and Foam
Synthetic Super Heavy Weight Racing Oil inhibits 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 metal-to-metal contact and wear that occurs when air is trapped in oil.

Viscosity Retention
Synthetic Super Heavy Weight Racing Oil resists viscosity loss due to the shearing forces found inside high-horsepower/high-stress racing engines. Its excellent viscosity retention ensures formation of a protective film between moving metal parts, which inhibits metal-to-metal contact and consequent wear and failure.

APPLICATIONS
AMSOIL Synthetic Super Heavy Weight Racing Oil is recommended for use in gasoline- or alcohol-fueled engines requiring an SAE 60, API SL/CF engine oil. It is not recommended for use in cold-temperature environments.

COMPATIBILITY
AMSOIL Synthetic Super Heavy Weight Racing Oil is compatible with conventional and synthetic motor oils. Mixing Synthetic Super Heavy Weight Racing Oil with other oils, however, will shorten its life expectancy and reduce the performance benefits. Aftermarket oil additives are not recommended for use with AMSOIL motor oils.

SERVICE LIFE
Follow the equipment manufacturer's recommended drain intervals.
