From the present investigation, we can draw the following conclusions;<br>   1) Increasing in alkyl chain length in the quaternary ammonium salt in the presence of NaSal increased the maximum temperature at which drag reduction can be sustained.<br>   2) The presence of the double bond in alkyl chain had a significant effect on lower temperature drag reduction limit.<br>   3) The DR effect of HMODA complexed with NaSal, which was replaced the methyl groups in TMODA with two 2-hydroxyethyl groups, gave better drag reduction in the wide temperature range 6–60
