  • LUBRICATING COMPOSITIONS WITH IMPROVED OXIDATION RESISTANCE CONTAINING A DISPERSANT AND AN ANTIOXIDANT
    Publication number: 20090325830
    Abstract: This invention relates to a lubricating composition comprising a major amount of an oil of lubricating viscosity with an iodine number less than about 9, (A) one or more antioxidant, and (B) from about 0.01% to about 3% by weight of at least one dispersant or detergent, wherein the total amount of antioxidant is at least about 2% by weight. The additives are useful act controlling oxidation of lubricants. Further, these lubricants have reduced viscosity increase caused by oxidation, while maintaining favorable carbon/varnish ratings.
