摘要

A fuel composition comprising a major amount of a gasoline fuel having a maximum sulfur content of 150 ppm by weight and a minor amount of at least one gasoline fuel additive having detergent action or having a valve seat wear-inhibiting action, wherein this gasoline fuel additive has at least one hydrophobic hydrocarbon radical having a number-average molecular weight (MN) of from 85 to 20 000 and at least one polar moiety, and wherein the fuel composition also has a content of at least one lower alkanol of from about 5 to 75% by volume.
