These include the antifoam additive application of the noted copending application where the polymer fraction of the total composition having {HEAD ~ low ethyl acrylate}, high 2 ethylhexyl acrylate content and high molecular weight functions well in hydrocarbon oil which at one use condition encounters relatively low temperatures while another fraction of the total polymer composition with high ethyl acrylate, {TAIL ~ low 2 ethylhexyl acrylate content} and low molecular weight functions well in such oil over a different higher use temperature condition range
