Zusammenfassung:PROBLEM TO BE SOLVED: To provide a lubricating oil composition for a plastic processing such as a press-forming, bend-forming, draw-forming, stroke-forming, not containing a chlorine compound and gentle for the earth, and exhibiting a good lubricating property for, a steel plate, a stainless steel plate, a surface-treated steel plate, an aluminum alloy plate. SOLUTION: This lubricating oil composition contains (A) 1 kind or >=2 kinds of organometallic compounds selected from a group consisting of zinc dithiophsphate, zinc dithiocarbamate, molybdenum dithiophsphate and molybdenum dithiocarbamate, (B) a sulfur-based extremely high pressure agent and (C) a dithiophosphoric acid ester.
