摘要：
Use of (a) an amino-based deposit control additive; and (b) a complex ester obtainable by an esterification reaction between (A) at least one aliphatic linear or branched C2 to C12 dicarboxylic acid, (B) at least one aliphatic linear or branched polyhydroxy alcohol with 3 to 6 hydroxy groups and (c) as a chain stopping agent (01) at least one aliphatic linear or branched C1-C30 monocarboxylic acid in case of an excess of component (B), or (C2) at least one aliphatic linear or branched monobasic C1-C30 alcohol in case of an excess of component (A); in a gasoline fuel composition for the purpose of providing a synergistic reduction in engine wear in a spark ignition internal combustion engine fuelled with said gasoline fuel composition.
