Abstract:
1. A lubricating base oil comprising saturated components of 97% by mass or greater, wherein the proportion of cyclic saturated components among the saturated components is not greater than 40% by mass, an iodine value of not greater than 2.5, wherein the kinematic viscosity at 100° C., the viscosity index and the pour point of the lubricating base oil are in a combination chosen from (a) a kinematic viscosity at 100° C. ranging from 2.0-3.0 mm (b) a kinematic viscosity at 100° C. ranging from 3.0-4.5 mm (c) a kinematic viscosity at 100° C. ranging from 4.5-20 mm wherein the mass ratio of monocyclic saturated components and bicyclic or greater saturated components among the cyclic saturated components satisfies the condition represented by the following inequality: wherein M
