AMSOIL RC Series lubricants are made from high-quality synthetic base stocks and additive systems. This product prevents wear and protects equipment by maintaining its viscosity, resisting thermal and oxidative breakdown, incorporating antiwear additives, preventing rust, and resisting the degrading effects of water.

Viscosity Characteristics
AMSOIL lubricants are very shear-stable and oxidationresistant, which prevents viscosity loss from mechanical shear and viscosity increase from oxidation. In addition, the high viscosity index and low pour points allow for extended temperature protection and performance. AMSOIL RC Series oils are fluid at cold temperatures—providing easier startups, quick lubricant circulation and limiting the need for sump heaters. At higher temperatures, AMSOIL maintains a thick lubricating film, reducing metal-to-metal contact and component wear.

Additive Performance
AMSOIL RC Series oils are formulated with complete additive technology, enhancing performance. The nondetergent, ashless antiwear additives in the RC Series provide an additional layer of protection against wear in severe conditions. Rust inhibitors protect critical components against corrosion in the presence of water or process contaminants, antioxidants increase the oil’s oxidation resistance, which extends lubricant life, and the foam suppressants prevent unwanted foaming and air entrapment.

Water Resistant
Hydrolytic stability (stability in the presence of water) and demulsibility (ability to readily separate from water) are important features provided by the RC Series lubricants. This increases lubricant life, prevents oil/water emulsions, and allows for reservoirs to be drained of water caused by the environment, processes or condensation. AMSOIL RC Series oils make use of a unique combination of synthetic base oils and additives to extend service life and provide clean, problem-free operation.

Application Recommendations
AMSOIL Synthetic RC Series oils are primarily recommended for gear and bearing applications and circulating systems requiring R&O and/or antiwear additive technology. RCE is a clear, nonstaining oil with an ISO-10 viscosity designed for high-speed spindles such as those found in textile applications.

The lighter viscosity AMSOIL RC Series oils (RCF-RCH) provide superior protection in high-and-low pressure gear, vane and piston hydraulic systems, compressors, highspeed bearings, small gear sets, pumps, high-speed spindles, high-speed gears, and many other industrial applications. Higher viscosity grades of RC oils, beginning with RCI (ISO 46) meet AGMA specifications for R&O and Synthetic gear oil specifications 1 through 8, respectively, for the lubrication of intermediate-speed equipment where mild shock loading and intermittent service are involved. These applications include machine tools, roller chains, gear reducers, cone drives, large motor bearings, medium speed ball and roller bearings, blowers, and worm gear sets. Consultthe manufacturer for properviscosity recommendations. The ability of RC Series oils to extend drain intervals is subject to operating environments and maintenance practices and should be monitored by oil analysis.

Although AMSOIL lubricants are compatible with mineral oil–based lubricants, for optimum performance it is recommended that the system be thoroughly drained and cleaned, if warranted.

NOTE: AMSOIL RC Series oils are not designed for applications requiring Extreme Pressure (EP) agents. For EP fortified lubricants, please refer to AMSOIL SG Series Gear Oils.
