Beschreibung
Zusammenfassung:	An ashless additive formulation, particularly suited for hydraulic oil applications, comprising a particular concentration of a monothiophosphate ester and a dithiophosphate ester was found to have improved performance properties and good compatibility with calcium containing packages. Lubricating compositions employing these monothiophosphate and dithiophosphate esters allow for low phosphorous content lubricating oil compositions.
