Abstract
Dispersing additives for lubricating fluids are disclosed, which contain the oxazoline function and are prepared by reacting amino alcohols with mono or bicarboxylic linear or branched chain aliphatic acids having from 2 to 51 carbon atoms. These additives are characterized by a very high dispersing power which makes them particularly suitable for engines used in stop-and-go service.
