Gear Lubricants Product Data castrol.com/GPS 800 255 4417 May 2025 GPS Castrol ® Alpha™ HC Castrol Alpha HC Lubricants are a series of ISO grade, technically advanced chemistries that exceed the performance levels historically attributed to the traditional synthetic products that are available today. Castrol Alpha HC Lubricants excel in applications requiring excellent oxidation control and thermal stability, consistent anti-wear performance, and low carbon forming tendencies, with chosen synthetic components that provide the potential for extended drain intervals and reduced maintenance costs. Castrol Alpha HC Lubricants have noted viscosity range properties for low temperature fluidity and controlled volatility. Other exceptional benefits of this innovative formulation include rust protection, consistent demulsibility and hydrolytic stability. Castrol Alpha HC Lubricants excel in circulating oil and gear set applications, and pass a 12 stage minimum in the demanding FZG spur gear test, which provides an additional margin of safety in the noted applications. (Please note that the Castrol Alpha HC Lubricants series should not be used for heavily loaded gear sets and where the OEM requires an AGMA [American Gear Manufacturers Association] EP lubricant.) Oxidation Control Castrol Alpha HC has increased oxidation resistance as evidenced by field test results in the RBOT Oxidation Life Test. is test showed that even aer 835 hours in use, Castrol Alpha HC's minutes to oxidation still exceeded that of new commercial mineral and synthetic fluids. is increased oxidation control contributes to outstanding deposit protection and extended compartment life. Castrol Alpha HC's oxidation resistance is also important for users who want to extend drain intervals in conjunction with a used oil analysis program. Wear Protection Castrol Alpha HC's anti-wear additives give it outstanding wear protection that ensures long component life and less maintenance and downtime. Low Temperature Performance Castrol Alpha HC's proven low temperature pumpability ensures that critical parts remain protected, even during extreme low temperatures. e added benefits of pumpability include more efficient operations and reduced energy consumption. Seal Compatibility Castrol Alpha HC is considered elastomer compatible and showed no damaging seal swell or increase in seal hardness. Other Qualities Castrol Alpha HC provides outstanding rust protection, consistent demulsibility and excellent hydrolytic stability. E12
