Royco 555 is a 5-centistoke synthetic based lubricating oil formulated specifically for gas turbine engines, helicopter gearboxes and transmissions. This turbine engine oil offers improved load carrying capacity, anti-wear, corrosion protection, and high thermal-oxidative stability due to a blend of hindered polyol esters and a carefully balanced modern technology additive pack
Royco 555 is a 5-centistoke synthetic based lubricating oil formulated specifically for gas turbine engines, helicopter gearboxes and transmissions. This turbine engine oil offers improved load carrying capacity, anti-wear, corrosion protection, and high thermal-oxidative stability due to a blend of hindered polyol esters and a carefully balanced modern technology additive package. Royco 555 can also be used safely in gas turbine engines with higher power outputs and difficult temperatures.
