Abstract: An improvement of the flow properties of paraffin-containing crude oil, more specifically, a means of favourably influencing the pour point of crude oil and hence improving the flow properties of paraffin-containing crude oil. The crude oil composition is a paraffin-containing crude oil and has an amount of an additive that brings about lowering of the pour point of the crude oil, wherein the additive comprises at least one copolymer composed of at least two comonomers, and wherein all comonomers that make up the copolymer are selected from the groups (a) and (b) of comonomers, and wherein group (a) is comonomers formed from acrylic acid and methacrylic acid, and group (b) is comonomers formed from styrene and a styrene derivative.
