PROBLEM TO BE SOLVED: To provide a lubricating oil composition for high-temperature applications which can suppress the evaporation amount in a thin film state and under high temperature and can maintain fluidity for a long time.SOLUTION: A lubricating oil composition for high-temperature applications is obtained by blending (A) a pyromellitic acid ester, (B) a sulfur-containing triazine antioxidant, and (C) a thiophosphoric acid ester antioxidant. When the lubricating oil composition for high-temperature applications is applied to chains, gears, bearings and the like, the evaporation amount can be suppressed for a long time, and fluidity can be maintained for a long time. |
