The present invention relates to the use of secondary alkanesulphonic acids as asphaltene dispersing agent in crude oils and products derived therefrom, wherein a chain length of 8 to 22 C atoms is present. The secondary alkanesulfonic acids are employed in an amount of from 1 to 10,000 ppm by volume. The alkanesulfonic acid is preferably formulated as a solution or microemulsion, and can further contain optional alkyl-formaldehyde resin, oxyalkylated amines, or wax-dispersing agents. The alkanesulfonic acids provide reduced precipitate amounts, slow the rate of precipitate formation, form a more finely divided precipitate and reduce the tendency of the precipitate to be deposited on surfaces.
