Abstract: The invention relates to the use of substituted monoureas, diureas, polyureas, monourethanes, bisurethanes, or polyurethanes of the formula R1X-CO-NR3R4, in which X represents R2N or O, and R1 to R4 represent hydrogen, alkyl groups, alkenyl groups, cycloalkyl groups, aryl groups, or aryl-alkyl groups independently of one another, wherein at least one variable must contain four carbon atoms and the urea or urethane functionality can be present multiple times via bridge elements, in order to further improve the cold flow properties of mineral oils and crude oils which already contain an additional organic compound that is suitable for dispersing or aiding the dispersion of paraffin crystals precipitated at low temperatures and an additional organic compound that improves the cold flow behavior of mineral oils and crude oils.
