Abstract
The present invention relates to a lubricant composition for a high temperature of which the amount evaporated in a thin film at a high temperature is controlled and of which the fluidity is maintained for a long period of time, and it is a lubricant composition for a high temperature which is obtained by mixing a base oil composition comprising (a) 20 to 100% by weight of a specific aromatic ester and (b) 0 to 80% by weight of another base oil with (c) 0.1 to 10% by weight, based on the total amount of the lubricant composition, of an antioxidant.
