Overview
ROYCO 481 is a mineral oil based lubricant formulated with modern additives to provide oxidation and corrosion protection as well as a high viscosity index for both low and high temperature fluidity. ROYCO 481 is recommended for lubrication of gas turbine engine components and as a flushing and preservative fluid for aircraft fuel systems and components. The high viscosity index provides for operations in a wide range of operating temperatures in high-speed turbines as well as gas turbine engines. ROYCO 481 may also be considered the primary turbine engine lubricant in many aircraft turbine engines designed to run on mineral-based lubricants.
