    摘要: The present invention provides a lubricating oil comprising an alicyclic compound represented by a general formula (I): wherein n is an integer of 0 or 1; one of R1 and R2 represents —CH2OR4 (wherein R4 represents a carboxylic acid residue) while the other one represents alkyl, lower alkyl-substituted or unsubstituted cycloalkyl, aryl, or aralkyl; and R3 represents —CH2OR5 (wherein R5 represents a carboxylic residue) and the like. The lubricating oil of the present invention has an excellent traction coefficient, excellent heat resistance, or the like. For the lubricating oil of the present invention, the alicyclic compound represented by the general formula (I) can be directly used as it is, and other base oils such as ester oil, poly-α-olefin, mineral oil, or silicone oil may be included therein, if necessary.
