<p>By using a lubricant base oil containing a dialkyl ether (A) represented by general formula (1), and also containing a dialkyl ether (B) represented by general formula (2) in the amount of 0.1-5.0 mass%, inclusive, the present invention provides a lubricant base oil which has low viscosity while also exhibiting excellent viscosity-temperature properties, low-temperature fluidity, and low friction properties. (In the formula, R1 and R2 each independently represent a C1-20 alkyl group, and n represents an integer of 1-20.) (In the formula, p and q each independently represent an integer of 1-20.)</p> |
