Abstract
The combination of a molybdenum compound and an aromatic amine has been found to produce a synergistic antioxidant effect when used as an antioxidant additive for lubricating oils. The combination has been found to be particularly effective under catalytic oxidation conditions, e.g. Fe catalysed oxidation of crankcase lubricating oils.
