    Abstract: Polyisobuteneamines of the general formula R1—CH2—NR2R3 in which R1 is a polyisobutyl radical which is derived from isobutene and up to 20% by weight of n-butene and has a number-average molecular weight Mn of from 600 to 770, and R2 and R3 are each independently hydrogen, a C1-C18-alkyl, C2-C18-alkenyl, C4-C18-cycloalkyl, C1-C18-alkylaryl, hydroxy-C1-C18-alkyl, poly(oxyalkyl), polyalkylenepolyamine or polyalkyleneimine radical or, together with the nitrogen atom to which they are bonded, are a heterocyclic ring are suitable as detergents in gasoline fuels, reduce valve sticking and improve the compatibility of the detergents with carrier oils and compatibility in fuel compositions which comprise a mineral fuel content and C1-C4-alkanols.

    Abstract: Novel fuels for gasoline engines comprise a synergistic mixture of a detergent additive component (A) and a synthetic carrier oil component (B), i) the detergent additive component (A) comprising at least one compound having a basic nitrogen atom which is substituted by a hydrocarbyl radical having a number average molecular weight of from about 500 to 1 300, and the detergent additive component (A) being contained in the fuel in an amount of from about 30 to 180 ppm by weight; and ii) the carrier oil component (B) comprising at least one compound of the following formula I R-O-(A-O)x-H (I) where R is a straight-chain or branched C6-C18-alkyl group; A is a C3- or C4-alkylene group; and x is an integer from 5 to 35; the carrier oil component (B) being contained in the fuel in an amount of from about 10 to 180 ppm by weight.
