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