    Abstract: Polyisobutenylphenol-containing Mannich adducts are prepared by a) alkylation of a phenol with highly reactive polyisobutene at below about 50° C. in the presence of an alkylation catalyst; b) reaction of the reaction product from a) with formaldehyde, an oligomer or a polymer of formaldehyde and at least one amine which has at least one secondary amino function and no primary amino function, or c) reaction of the reaction product from a) with at least one adduct of at least one amine which has at least one secondary or primary amino function and formaldehyde, an oligomer of formaldehyde, a polymer of formaldehyde or a formaldehyde equivalent, and are used as detergent additives in fuel and lubricant compositions, and additive concentrates, fuel compositions and lubricant compositions contain these Mannich adducts.

    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: 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.
