MOTOR FUEL COMPOSITION HAVING ENHANCED WATER TOLERANCE (D#80,992 -F) A motor fuel composition comprising a base fuel and: (I) the reaction product of (a) a hydrocarbyl-substituted dibasic acid anhydride and (b) a polyoxyalkylene diamine; (II) a polymeric component which is a polyolefin polymer/copolymer or the corresponding aminated or hydrogenated polymer/copolymer, or mixtures thereof; (III) a polyalkylene glycol having a molecular weight in the range of 500-2000; (IV) a lubricating oil composition, and (V) a polyoxyalkylene adduct of a linear or branched aliphatic alcohol, or an alkyl phenol. The adduct is employed as a surfactant additive and in an amount sufficient to enhance the water tolerance of the motor fuel composition. 80992ps.dgv
