    Abstract: The invention relates to a method for manufacturing a lubricant additive to fuel, using fatty-acid compounds. In the method, saturated fatty acids, which are esterified and possibly aminated, with a high melting point are separated from a fatty-acid mixture by cooling, the mixture thus obtained being mixed again with the part of the original fatty-acid mixture from which the fatty acids with a high melting point have been separated, the necessary amount of this latter mixture being mixed with fuel as a lubricant. The fatty-acid mixture is separated in the presence of a solvent or solvent mixture containing alcohol groups and the solvent or solvent mixture are used to esterify the removed fatty acids. The said solvents are removed from the mother liquor and the esterified fractions are combined with the residue of the mother liquor and used as an auxiliary agent in fuel.
