    Abstract: A gasoline-based fuel composition with a sulfur content of not more than 150 ppm containing small amounts of fuel additive(s) (I) with a detergent or valve seat wear-inhibiting action, in which (I) contain hydrophobic hydrocarbon residue(s) with a number-average mol. wt. of 85-20000 and a polar group and the composition also contains 5-75 vol% lower alkanol(s). An independent claim is also included for a method for improving the efficacy of detergent or valve seat wear-inhibitor additives in low-sulfur fuel by adding a lower alcohol.

    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.

    Abstract: Fuel compositions for internal combustion engines, comprising a principle amount of a liquid hydrocarbon fuel and an amount, which has a cleaning effect, of at least one propoxylate additive of the formula I where n is an integer from 10 to 20 and R 1 is straight-chain or branched C 8 -C 18 -alkyl or C 8 -C 18 -alkenyl, if required in combination with at least one detergent additive, e.g. a polyalkylamine additive of the formula II R 2 -NH 2 (II) where R 2 is a straight-chain or branched polyalkyl radical having a number average molecular weight of from about 500 to about 5000, and fuel additive compositions which contain propoxylates of the formula I and, if required, further additives, such as the aforementioned polyalkylamines of the formula II, as intake valve cleaners.
