Low sulfur diesel fuel, neat biodiesel (RME), i.e. rapeseed oil methyl ester, and blends of ON diesel fuel with 5 % (B5) and 20 % (B20) of RME were treated with two additives influencing flow and storage properties (depressants of the WAFI type). The fuels with the addition of the depressants as well as those without the depressants were tested with the use of standard methods involving the determination of cloud point (CP), cold filter plugging point (CFPP), simulated filter plugging point (SFPP), and pour point (PP). After establishing the minimal depressant concentrations at which the value of CFPP was not higher than –20 oC, the fuels were conditioned for 64 hours in the temperature of -17oC (sedimentation test). After the completion of the test, both CP and CFPP were determined in the samples taken from the upper and lower layers of the fuels. The blends B5 and B20 treated with the additive R442 failed the low-temperature sedimentation test; after its completion, the presence of white sediment was recorded in lower layers of the fuels, the CFPP grew by 11-12 oC, and, in the case of the B20 fuel, the CP increased by 6 oC as compared to that prior to the test.
