PURPOSE:To obtain a lubricating oil composition having extremely improved permeability and drapability to sliding faces, preventing dry up of oil, by mixing a specific fluorine-containing organosiloxane with an ester-based lubricating oil. CONSTITUTION:The aimed composition obtained by mixing (A) an organosiloxane containing both of 5-40C hydrocarbon group containing ester group and polyfluoroalkyl group with (B) an ester-based lubricating oil in the weight ratio A/B of more preferably 0.1/99.9-20/80. A component having 1-50wt.% (preferably 3-40wt.%) fluorine content, 30-80wt.% (preferably 35-70wt.%) non-fluorine hydrocarbon group content and <=50wt.% (preferably <=40wt.%) SiO content is used as the component A. |
