PURPOSE:To obtain the title compsn. which is excellent in infiltrability into sliding faces, conformability, oil shortage preventing effect, heat resistance and chemical resistance, by adding a particular organosiloxane to a hydrocarbon lubricating oil. CONSTITUTION:A hydrocarbon lubricating oil (A) comprising as a base oil a mineral oil, an olefinic polymer synthetic oil or a synthetic oil of a condensate from a chloroparaffin and an arom. ring is blended with an organosiloxane (B) having both of a polyfluoroalkyl group and a 5-22C long-chain alkyl group, of which the fluorine content is 1-50wt.%, the content of alkyl groups contg. a long-chain alkyl group is 30-80wt.% and the SiO2 content is 50wt.% or below, in a B to Awt. ratio of 0.05-99.0/99.95-1.0, pref. 0.1-20/99.9-80, and optional components (C) such as a viscosity index improver, a pour point depressant, an antioxidant, and a detergent-dispersant. |
