FIELD: chemistry.

SUBSTANCE: invention relates to a fuel composition and a method for the production of a fuel composition. The method includes obtaining of quaternary ammonium salt by reaction of (a) tertiary amine with the formula R¹R²R³N, where R¹, R² and R³, each independently, is an optionally substituted hydrocarbyl group, with (b) an alkylating agent activated by acid in the presence of (c) a compound with the formula HOOCXCOO-(R⁴O)_n-R⁵, where R⁴ is an optionally substituted alkylene group, R⁵ is hydrogen or an optionally substituted alkyl, alkenyl or aryl group, X is an alkylene group substituted with alkyl or alkenyl, and n is equal to 0 or a positive integer, provided that n is not equal to 0, if R⁵ is hydrogen; and mixing of quaternary ammonium salt with fuel; where n is a positive integer and/or X is CH₂CHR or CHRCH₂, where R is an alkyl or alkenyl group with from 20 to 24 carbon atoms.

EFFECT: obtaining a fuel composition.
