LUBRICANT COMPOSITION, AND, LUBRICANT OIL CONCENTRATE. An improved storage stability lubricant composition comprising a greater amount of a lubricant viscosity lubricating oil, at least one alkali metal borate, at least one polysulfide mixture having at least 40% tetrasulfide or higher dihydrocarbyl sulfides, is disclosed. and at least one non-acidic phosphorus compound comprised of a trihydro carbyl phosphate and a dihydrocarbyl dithiophosphate derivative. In addition to improved storage stability, the composition has improved wear performance when the polysulfide ratio is controlled. |
