Boron-containing lubrication 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 corres...
