Abstract
An object of this invention is to provide a lubricating base oil that has a small rate of change in viscosity (a high viscosity index) over a wide temperature range, low viscosity at low temperatures, and good low-temperature fluidity and evaporation resistance, and that allows reduced decomposition thereof. To achieve the object, methylpentanediol diesters obtained by using specific aliphatic monocarboxylic acids are used as a lubricating base oil.
