AMSOIL Synthetic Super Heavy Weight Racing Oil is formulated specifically for wear protection and friction reduction in the extreme service conditions of racing.  It has been proven on-track to bring down high engine oil sump temperatures by 20 degrees F, which speaks directly to its ability to reduce friction, promote power and inhibit wear.

MOTORCYCLE APPLICATIONS
AMSOIL Synthetic Super Heavy Weight Racing Oil is formulated with a complete American petroleum Institute (API) SJ/CD additive system.  AMSOIL Synthetic Super Heavy Weight Racing Oil may be used in all engines for which API SJ/CD SAE 60 oils are specified.

AMSOIL Synthetic Super Heavy Weight Racing Oil is also formulated with a complete Japan Automobile Standards Association (JASO) MB additive system.  AMSOIL Synthetic Super Heavy Weight Racing Oil may be used in motorcycles requiring JASO MB oils.  Such engines include vintage and classic motorcycles, often equipped with air-cooled engines, and specifying straight grade SAE 60 oils. 

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 allows oil to flow freely without significant "boil-off" 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 metal-to-metal contact and wear that occurs with foamy oils.  

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.

APPLICATION
AMSOIL Synthetic Super Heavy Weight Racing Oil is recommended for applications requiring the following specifications:

• API SL, CF
• JASO MB

AMSOIL Synthetic Super Heavy Weight Racing Oil is not recommended for use in cold temperature applications.

MIXING AMSOIL
AMSOIL Synthetic Super Heavy Weight Racing Oil may be mixed with petroleum-based oils or with other synthetic oils.  However, a mixture of AMSOIL Synthetic Super Heavy Weight Racing Oil may not provide as much protection as unadulterated AMSOIL Synthetic Super Heavy Weight Racing Oil.

SERVICE LIFE
Follow engine manufacturer's oil drain interval recommendations when using AMSOIL Synthetic Super Heavy Weight Racing Oil.

Race Engines: specified by Owner Experience/Oil Analysis

Motorcycles and Recreation Vehicles: change according to manufacturer's recommendations, without oil filtration. With oil filtration (AMSOIL SDF Filter), up to 2 times longer than manufacturer's recommendations or 6 months, whichever comes first. If a Hastings or other filter is used, filter should be changed at manufacturer recommendations.
