摘要： A lubricant in the form of lubricating oil or grease, for use in contact with graphite or molybdenum disulfide or in contact with aluminum materials, which comprises a perfluoropolyether oil free from (CF2O)n groups as a repeat unit of polymer and having a kinetic viscosity at 40° C. of 50-1,500 mm2/sec., as a base oil, where F(CF2CF2CF2O)mC2F5 or RfO[CF(CF3)CF2O]p(CF2CF2O)qRf′ s used as the perfluoropolyether base oil. The lubricant undergoes no considerable deterioration of high-temperature characteristics (high-temperature durability), even if used in various uses as mentioned above, and also has distinguished low-temperature characteristics when the base oil has a kinetic viscosity of 50-250 mm2/sec.
