Abstract (en)
[origin: WO2013063177A1] The present invention relates to lubricating compositions and particularly gear oil compositions that include a minimum level of a specific antioxidant component, where the antioxidant component includes (i) a phenolic antioxidant, (ii) an aminic antioxidant, or (iii) a combination thereof, where the antioxidant component is present in the lubricating composition at from 1.0 percent by weight or higher. Such compositions provide surprisingly good seal compatibility.
