The composition of the polymer additives and the size of the molecules were tailored to be soluble and to significantly lower the pour point of various types of fuels, lubricants, biofuels, biolubricants and corresponding blends. Even at low concentrations of 0.2 wt %, additive improves the pour point (ASTM D 5950) of biodiesel by 9 °C, canola oil and crude oil by 12 °C, lubricating oil by 27 °C and diesel by 30 °C, thus extending the range of application of the above mentioned fuels, lubricants, biofuels and biolubricants from -6 °C to -48 °C.
