Zusammenfassung:BORON-CONTAINING LUBRICATING OILS HAVING IMPROVED FRICTION STABILITY Lubricating oil compositions having excellent friction stability comprise a base lubricating oil, an oil soluble source of phosphorus and a defined polyalkylene polyamine-based friction modifier that has been reacted with a borating agent to convert at least one secondary amine group into the corresponding boric acid ester or boric acid salt.
