Abstract: A method of introducing a drag reducing polymer into a pipeline such that the friction loss associated with the turbulent flow though the pipeline is reduced by suppressing the growth of turbulent eddies. The drag reducing polymer is introduced into a liquid hydrocarbon having an asphaltene content of at least 3 weight percent and an API gravity of less than about 26° to thereby produce a treated liquid hydrocarbon. The treated liquid hydrocarbon does not have a viscosity less than the viscosity of the liquid hydrocarbon prior to treatment with the drag reducing polymer. Additionally, the drag reducing polymer is added to the liquid hydrocarbon in the range from about 0.1 to about 500 ppmw.
