Formulated from highly refined base stocks and an additive system which provide an extremely high level of chemical and thermal stability, rapid and complete separation from water and a high resistance to emulsification. Provides excellent protection against rust and corrosion, including resistance to salt water, and good antiwear properties. They have a high viscosity index which ensures minimum variation of film thickness with temperature and minimum power loss during the warm up period. These grades have excellent air release properties which allow entrained air to separate, thus avoiding pump cavitation and erratic operation. Features and Benefits: Very high level of chemical and thermal stability and resistance to sludging and varnishing means long oil charge life in circulation systems and reduced oil replacement and maintenance costs. Excellent water release properties and improved operating efficiency. Long term protection against rust and corrosion and high resistance to foa
