Abstract
A motor fuel composition comprising a mixture of hydrocarbons in the gasoline boiling range containing in combination a reaction product component and a polyolefin polymer/copolymer component is described. The reaction product component is the reaction product of maleic anhydride, a polyether polyamine, and a hydrocarbyl polyamine. The polyolefin polymer/copolymer component is the polymer, copolymer, or corresponding hydrogenated polymer or copolymer of a C.sub.2 -C.sub.6 unsaturated hydrocarbon, said polymer or copolymer having a molecular weight in the range of 500-3500, preferably 650-2600.
