Abstract
It has been found that a lubricating oil containing: (1) an alkali metal borate; (2) an oil-soluble sulfur compound; (3) a dialkyl hydrogen phosphite; and (4) a mixture of neutralized phosphates said phosphates being essentially free of monothiophosphates interacts synergistically to provide a lubricant with superior load carrying properties.
