Method of treating petroleum hydrocarbon liquids to inhibit the fouling of refinery process equipment involving the addition of an anti-fouling amount of an oil-soluble addition type copolymer containing in combined form as its essential monomeric components copolymerizable ethylenically unsaturated compounds each containing only one polymerizable ethylenic linkage, at least one of which component is amine free and contains from 4 to about 18 carbon atoms, one of the components contains a basic aminonitrogen in the side chain and one of the components contains a hydrocarbon-substituted-amide in the side chain.
