Patent number: 8093190
Abstract: 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.

Patent number: 7935663
Abstract: Novel molybdenum compounds are prepared by reacting a hindered amine with a molybdenum source, in the presence of one of (a) water, (b) a diol and water, and (c) the reaction product of a fatty oil and a multifunctional amine, and water. Lubricant compositions containing these new compounds are more stabilized against oxidation and have improved friction reducing properties. Synergy is observed when the novel compounds are combined with a diaryl amine in a lubricant composition.
