Zusammenfassung:	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 an acylating agent to convert at least one secondary amine group into an amide. Des compositions d'huile lubrifiante ayant une excellente stabilité de friction comprennent une huile lubrifiante de base et une source de phosphore soluble dans l'huile et un agent modificateur de friction à base de polyalkalène polyamine défini qui a été mis en réaction avec un agent d'acylation pour convertir au moins un groupe amine secondaire en un amide.
