摘要：
An antioxidant lubricant composition has at least 50 wt % of a lubricating base oil and an oil-soluble metal compound providing between 1 and 2,000 parts per million of metal to the lubricant composition, the metal compound being chosen from the group consisting of molybdenum, tungsten titanium and boron compounds, and an oil-soluble hindered amine providing between about 0.001 and about 2 wt % of oil-soluble hindered amine to the lubricant composition, and optionally, an oil-soluble diarylamine providing between 0.001 and about 2 wt % of oil-soluble diarylamine to the lubricant composition.
