FIELD: oil and gas industry.

SUBSTANCE: present invention refers to oil processing and petrochemistry. The essence of the invention is as follows: the additive contains, wt %: alkyl(C₃-C₁₈)nitrate 75-90, corrosion-inhibiting component 5-15, and a hydrocarbon fraction boiling out within range of 120-270°C to 100. The corrosion-inhibiting component is chosen from a group including 3,4,4-trimethyl-2-phenyloctaneacid, 2-imidazoline, alkyl(C₄-C₉)thiazolidine, and N-oleilsarcosyne. The additive can additionally contain copolymer on base of ethylene-not saturated monomers at volume of 0.5-1.5 % wt. Diesel fuel on base of main fuel contains the above described additive at volume of 0.01-0.8% wt. Also as base fuel there is contained oil diesel fuel or gas condensate fuel.

EFFECT: upgraded corrosion-inhibiting and starting properties, also increased period of storage to 2-3 years.
