ORI-INHIBITED MOTOR FUEL COMPOSITION AND STORAGE STABLE CONCENTRATE (D#78,885-C1-F) ABSTRACT An motor fuel composition which inhibits engine ORI and intake valve deposit formation comprises a mixture of hydrocarbons boiling in the range of 90°F-450°F and the reac- tion product of a hydrocarbyl-substituted dibasic acid anhydride and a polyoxyalkylene diamine; it may optionally aditionally comprise a polymeric component which is a polyolefin polymer, copolymer, or the corresponding aminated or hydrogenated polymer or copolymer, or mixtures thereof, of a C2-C10 hydrocarbon. Motor fuel compositions of the instant invention show improved ORI control in comparison with typical commercial fuel compositions. The instant invention is advantageous in that it may be produced and stored as a precipitation-resistant concentrate composition.
