Abstract: Multifunctional additives for lubricating oils containing n-paraffins, said additives comprising a solvent and a blend of polymers containing(I) from 10 to 99 percent by weight of one or more polymers P1 composed of monomers of(A) esters of methacrylic acid, acrylic acid, or both(a) with a linear alcohol having from 16 to 30 carbon atoms,(b) with a branched alcohol having from 8 to 40 carbon atoms, and optionally, other alcohols, and(II) from 1 to 90 percent by weight to one or more polymers P2 composed of monomers of(A') esters of methacrylic acid, acrylic acid, or both(a') with a linear alcohol having from 16 to 30 carbon atoms, and, optionally other alcohols.
