Abstract: The invention concerns reaction products of polyisobutylenes having an average polymerisation degree P of 10 to 100 and a proportion E of 60 to 90 % of double bonds which can be reacted with maleic acid anhydride, E corresponding to 100 % of the calculated theoretical value if each polyisobutylene molecule has a reactive double bond of this type, with nitrogen oxides or mixtures of nitrogen oxides and oxygen. These reaction products are suitable as fuel additives, in particular for spark-ignition engines, and as lubricant additives.
