METHODS AND COMPOSITIONS FOR REDUCING WEAR IN INTERNAL COMBUSTION ENGINES LUBRICATED WITH A LOW PHOSPHOROUS CONTENT BORATE-CONTAINING LUBRICATING OIL

摘要

Disclosed are methods and lubricant compositions for reducing wear ininternal combustion engines lubricated with a low phosphorous contentlubricating oil. The lubricant compositions of this invention comprise asynergistic combination of a dispersed, hydrated, alkali metal borate and atleast one phosphorous-containing compound wherein the total phosphorousemployed in the composition is no more than about 0.08 weight percent basedon the total weight of the composition.
