The types and action mechanism of depressant additions, which improves the properties of diesel fuels in low temperatures, were presented. The results of a sixteen different depressants influence on cloud point (CP) and cold filter plugging point (CFPP) of diesel fuels ONA without additions are given in following elaborate. The depressants were applied to samples of diesel fuel in concentration between 500 and 5000 ppm. The present paper shows correlation of diesel fuels ONA CFPP and ΔCFPP depression between depressants concentration. Only a part from the tested depressant additions has a significant impact on diesel fuel cloud filter plugging point at concentration recommended by their manufacturers. Moreover, some of the additions do not decrease the CFPP value. The depressants can be divided into three groups by their effectiveness: first, the ones which decreases greatly the CFPP (from 3 to 11 degrees) by adding only small amount of them (500 ppm), second, with almost no influence on CFPP values in smaller amounts (500 ppm) but reducing CFPP values in larger quantities (to 5000 ppm), third, with no influence on diesel fuels ONA CFPP even in large concentration. In conclusion, lowering the CFPP value depends on the kind of depressant and its concentration in diesel fuel and not on the diesel hydrocarbon composition with addition up to 7% of Fatty Acid Methyl Ester (FAME).
