摘要

"ANTIOXIDANT SYSTEM, LUBRICANT OIL, METHODS FOR ENGINE LUBRICATION, LUBRICANT OIL PRODUCTION AND TO REDUCE OXIDATION IN AN INTERNAL COMBUSTION ENGINE, AND USE OF ANTIOXIDANT SYSTEM". This invention is directed to an antioxidant system for use in lubricating oils comprising sulfurized isobutylene and hindered phenols which provides increased oxidation resistance and is particularly useful in gas engines to the method for producing such oxidizing systems to lubricating oils. which comprise the antioxidant system and methods for lubricating engines using a lubricating oil, which comprise this antioxidant system.
