PROBLEM TO BE SOLVED: To achieve sludge suppression, oxidation stability, rust prevention and lubricity at a high level and in a good balance, and when used as a compressor oil, the oil change interval can be extended to about 6000 to 12000 hours. It is another object of the present invention to provide a lubricating oil composition that does not clog a mist separation filter even when used in a rotary gas compressor having a mist separation mechanism with a stray mist amount of less than 0.02 g / Nm 3 . SOLUTION: The lubricating oil composition of the present invention comprises a lubricating base oil, at least one selected from metal detergents, ashless dispersants, and dispersion type viscosity index improvers, a rust inhibitor, and a phosphorus compound. It is characterized by containing. [Selection figure] None |
