    Abstract: A fuel oil composition containing a minor proportion by weight of a mixture of 20 to 40 wt % of a polyphenol, a sulphurized polyphenol or a hindered phenol and 80 to 60 wt % of a cyclic amide derived from a dicarboxylic acid or anhydride having a hydrogen-and-carbon containing substituent of at least 40 carbon atoms and a polyalkylene polyamine having at least 2 nitrogen atoms and at least 3 carbon atoms (other than carbon atoms in the branched substituents) between the terminal amino groups.A suitable additive is a 70% by weight of the macrocyclic derivative of polyisobutenyl succinic anhydride (MW 1300) and penta propylene hexamine and 30% by weight of 4,4.sup.1 methylene bis (2,6 di tert butyl phenol).
