Please note: International orders are shipped from their respective locations, which may take an additional 7-10 days to process. We strive to consolidate items into one shipment to minimize duties and taxes. However, if items are located in different locations, separate shipments may be necessary.
ROYCO 481 is a mineral oil based lubricant formulated with modern additives for gas turbine engines and aircraft fuel systems, to provide oxidation and corrosion protection as well as high viscosity index for both low and high temperature fluidity.
ROYCO 481 is recommended for the lubrication of gas turbine engine components, as well as a flushing and preservative fluid for aircraft fuel systems and components. It provides exceptional oxidation resistance, corrosion protection and the high viscosity index enables stable operation over wide temperature extremes in high-speed turbines as well as gas turbine engines. ROYCO 481 may also be considered as the primary turbine engine lubricant in many aircraft turbine engines designed to run on mineral based lubricants.
