An amine mixture includes a polyisobuteneamine and an aliphatic amine. The amine mixture is obtained by reductive amination of a mixture with ammonia or an amine HNR2R3. The mixture can be a mixture of the oxo process product formed in the hydroformylation of polybutene or polyisobutene and an alkanol R4-OH. The mixture can also be a mixture of the epoxide formed in the epoxidation of polybutene or polyisobutene and an alkanol R4-OH. Or, instead, the mixture can be a mixture of the nitro compound formed in the reaction of polybutene or polyisobutene with nitrogen oxides and an alkanol R4-OH. The amine mixture is suitable for cleaning and keeping clean intake valves and injection nozzles in gasoline engines.
