Castrol Perfecto XPG 32 is formulated from unique highly refined base oils coupled with complex additive technology to provide exceptional resistance to the formation of insoluble degradation products that ultimately deposit out as varnish, however without compromise to its anti-wear performance. Perfecto XPG 32 is primarily intended for the lubrication of highly loaded industrial gas turbines whether on base load or intermittent running where high local temperatures during operation and the heat soaking period during run down are experienced. Perfecto XPG 32 possess the requisite air release, foaming and water separation properties for steam turbines making them suitable for gas and steam turbines in single train sharing a common oil reservoir.
