Lubricating compositions |
摘要 |
Crankcase lubricant compositions for use in automobile or truck engines comprise a major amount of a lubricating oil, added copper present in oil-soluble form and an oil-soluble diamine sulphide. The specified additives provide a highly effective antioxidant system, which may be used, for example, in lubricating oils which are substantially free of phosphorus.
