ROYCO 555 was specifically developed for use in high performance gas turbine engines developed during the mid 1960's for the SST and Concorde. These advanced engines required a lubricant having good high temperature stability as well as extreme pressure load carrying capability. ROYCO 555 was developed for the demands of increasingly higher power output engines that subsequently develop higher operating temperatures and loads.
