Sweeney, W M; Lachowicz, D R

A middle distillate fuel composition is described comprising: (a) a major portion of a middle distillate containing a hydrocarbon boiling in the middle distillate boiling range; (b) an extending portion of a vegetable oil; and (c) an effective thermal-stabilizing amount of a nitrogen-containing polymer prepared by reacting an ethylene/propylene copolymer with maleic anhydride, thereby forming a succinic anhydride, reacting the succinic anhydride, with an alcohol, thereby forming a succinate ester while leaving a portion of the succinic anhydride unreacted, and, reacting the succinate ester and the unreacted succinic anhydride with dimethylaminopropylamine, thereby forming a nitrogen-containing polymer.
