    摘要: This invention discloses a lubricant suitable for use in percussion equipment. The lubricant comprises a base oil selected from the group consisting of Group I or Group II, blended in a synergistic amount with a gear oil package and a friction modifier. The lubricant exhibits superior wear and superior extreme pressure properties due to the synergistic effect of the gear oil package and the friction modifier. In a preferred embodiment, the gear oil package comprises a polyalkyl methacrylate polymer, and the friction modifier comprises a synthetic ester.
