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: The invention relates to polyalkene amine formulations comprising at least o ne polyalkene amine in a solvent. Said formulations have improved applicational properties, especially at low temperatures. The invention also relates to a method for the production of said formulations, in addition to the use there of in fuel and lubrication compositions, especially fuels, in order to improve the effects of said fuel on the cleaning of the inlet system.
