FIELD: chemistry.
SUBSTANCE: invention relates to fuel additives, particularly a method of increasing stability of diesel biofuel during storage. The method involves adding a liquid starting solution containing 15-60 wt %, with the respect to the starting solution, 2,6-di-tert-butylhydroxytoluene which is dissolved in diesel fuel in doses to stabilised diesel biofuel until achieving concentration of 0.005-2 wt % of 2,6-di-tert-butylhydroxytoluene, with respect to the weight of the solution of the diesel biofuel.
EFFECT: method increases stability of diesel biofuel during storage, said diesel biofuel being obtained from alkyl esters of fatty acids, wherein stability during storage implies reduction in turbidity of the diesel biofuel.
