The present invention relates to dicarboxylic acid derivatives containing no heavy metals, and wear-resistant agents and lubricant compositions containing the same. The lubricating oil composition containing the dicarboxylic acid derivative compound according to the present invention is superior in wear resistance performance to the conventional lubricating oil composition and exhibits a superior effect even when used in a content lower than that of the conventional lubricating oil composition and is environmentally friendly because it does not use heavy metals Lubricating oil, lubricating oil or processed oil additives, lubricating oil, engine oil, transmission lubricating oil, gear oil, turbine oil, operating oil, refrigerator oil, compressor oil, vacuum pump oil, bearing oil, sliding oil, . ≪ / RTI > |
