Castrol Perfecto T range of turbine oils is formulated from highly refined mineral base stocks together with rust and oxidation additives to extend their inherent oxidation stability and corrosion protection.The Perfecto T range is primarily intended for the lubrication of steam turbines because of its resistance to foaming, demulsification performance and its air release properties. It can also be used in lightly loaded industrial gas turbines where anti wear performance is not required and turbo machinery where hydrodynamic lubrication prevails.
