The invention relates to polyisobutenamines of formula R-X, where R = a polyisobutenyl group with a number average molecular weight MN within the range 500 to 1500, with a polydispersity Mw/MN below 1.4 and X = an organic residue comprising an amino group, a method for production and use thereof as detergent additives in fuel compositions. The invention further relates to additive concentrates, which comprise at least one polyisobutenamine at a concentration of 0.1 to 80 wt. %. |
