ABSTRACT:
This invention relates to antioxidant compositions comprising (A) at least one secondary diarylamine, (B) at least one sulfurized olefin and/or sulfurized hindered phenol, and (C) at least one oil soluble molybdenum compound. These antioxidant compositions are highly effective at providing oxidative stability to lubricating compositions, especially for highly saturated, low sulfur lubrication base oils.
