PROBLEM TO BE SOLVED: To provide a gear oil additive composition with corrosion reducing effect to yellow metal components of axles and transmissions, particularly copper and copper alloys, and to provide a method for reducing yellow metal corrosion of axles and transmissions. SOLUTION: The gear oil additive composition comprising organic polysulfides containing at least 30 wt % of a dialkyl polysulfide compound or mixture of dialkyl polysulfide compounds, a thiadiazole, and at least one ashless phosphorus-containing wear inhibitor compound as the components that reduce the yellow corrosion in axles and transmissions. The gear oil composition contains the same. COPYRIGHT: (C)2005,JPO&NCIPI |
