| Abstract | 57 ABSTRACT A base oil for a lubricating oil and a lubricating oil composition containing said base oil, which are to be used in a mechanical apparatus with an orifice mecha nism, are disclosed. The base oil has a kinematic viscos ity at 40 C. or 3 to 500 cSt, a pour point of -25 C. or lower and a cloud point of -25 C. or lower. The lubri cating oil composition contains as major components (A) the above base oil and (B) at least one additive selected from a viscosity index improver, a pour point depressant, an extreme pressure agent, an anti-wear agent, an oiliness agent and an antioxidant. The base oil and the lubricating oil composition are excellent in working properties at low temperatures and thus can be effectively used in a mechanical apparatus with an ori fice mechanism, particularly to be used at low tempera tures. |
