Abstract: The factors that impact on drag reducing additives (DRA) efficiency may be divided on external and internal. External ones include pipe properties, liquids nature and mode of oil/oil product pumping while internal stand for polymer chain length and chemical formula of macromolecules that defines a solubility of a polymer.
The matter of this paper is to determine the effect of temperature and composition of diesel fuel on drag reduction. The samples of diesel of different producers were chosen for research.
Laboratory flow loop device was used at a flow rate of 5 cubic meters per hour. In spite of the equal DRA content in diesel the hydrodynamic properties differ from sample to sample. The cause of such a behavior is discussing. In comparison of diesel composition and the temperature the last factor has a much greater influence on DRA efficiency.

Keywords: DRA, drag reduction, wax, polycyclic aromatic compound, flow loop drag testing device.
