ABSTRACT:
Disclosed are methods and lubricant compositions for reducing wear in internal combustion engines lubricated with a low phosphorous content lubricating oil. The lubricant compositions of this invention comprise a synergistic combination of a dispersed, hydrated, alkali metal borate and at least one phosphorous-containing compound wherein the total phosphorous employed in the composition is no more than about 0.08 weight percent based on the total weight of the composition.
