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-fuelled, 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.

Applications

Recommended for use in gasoline- or alcohol-fuelled engines requiring an SAE 60, API SL/CF engine oil. It is not recommended for use in cold-temperature environments.

Performance Features

• Excellent heat stability
• Highly resistant to thermal degradation and oxidation
• Maintains viscosity
• Resists the formation of sludge, varnish, deposits or acids for continued wear protection
• Reduced oil consumption
• Inhibits thickening
• Allows oil to flow freely for dependable engine lubrication and protection
• Inhibits corrosion, rust and foam
• Ensures protection against metal-to-metal contact and wear
• Resists viscosity loss due to the shearing forces
• Viscosity retention ensures formation of a protective film between moving metal parts
