PROBLEM TO BE SOLVED: To easily obtain a lubricating oil high in extreme-pressure performance anywhere by reinforcing a lower oil. SOLUTION: In a reinforcing agent for increasing the extreme-pressure performance of a lubricating oil, with a base oil composed of a mineral oil or a synthetic oil or a mixture thereof is compounded 14-17 mass %, based on the total amount, lauric acid phosphate or tricresyl phosphate or a mixture thereof as the phosphorus-based extreme pressure agent and 55-75 mass %, based on the total amount, dibenzylsulfide as the sulfur-based extreme pressure agent. |
