Abstract 1. A PETROLEUM DISTILLATE FUEL HAVING A BOILING RANGE WITHIN THE LIMITS OF ABOUT 250* F. AND ABOUT 700* F. WHICH HAS BEEN IMPROVED WITH RESPECT TO ITS LOW TEMPERATURE FLOW PROPERTIES BY ADDING THERETO: (A) ABOUT 0.05 TO 2.5 WT. PERCENT OF AN ESSENTIALLY SATURATED AMORPHOUS NORMALLY SOLID PETROLEUM HYDROCARBON FRACTION HAVING A MELTING POINT IN THE RANGE OF ABOUT 80* TO 140* F. AND A NUMBER AVERAGE MOLECULAR WEIGHT WITHIN THE RANGE OF ABOUT 475 TO 3000, SAID HYDROCARBON FRACTION BEING SUBSTANTIALLY FREE OF NORMAL PARAFFIN HYDROCARBONS, AND (B) ABOUT 0.005 TO 0.5 WT. PERCENT OF A FUEL-SOLUBLE ADDITIVE COMPOUND SELECTED FROM THE GROUP CONSISTING OF: (I) A HALOGENATED ETHYLENE-CONTAINING POLYMER HAVING A HALOGEN CONTENT OF FROM 1 TO 40 WT. PER CENT, AND (II) A HYDROCARBYL SUCCINAMIC ACID MATERIAL OF THE FORMULA; R-CH(-CO-X2)-CH2-CO-X3 WHEREIN R IS A STRAIGHT CHAIN ALIPHATIC HYDROCARBON HAVING FROM 0 TO 1 SITE OF OLEFINIC UNSATURATION OF FROM 14 TO 40 CARBON ATOMS AND ATTACHED AT A SECONDARY CARBON ATOMS TO THE SUCCINYL GROUP; ONE OF X2 AND X3 IS -NYY1, WHEREIN Y AND Y1 ARE ALIPHATIC HYDROCARBYL GROUPS OF FROM 14 TO 40 CARBON ATOMS, THE OTHER OF X2 AND X3 IS OF THE FORMULA: -OH(NHY2Y3)N WHEREIN N VARIES FROM 0 TO 1, Y2 AND Y3 ARE HYDROGEN, ALIPHATIC HYDROCARBON OF FROM 1 TO 30 CARBON ATOMS OR OCYALIPHATIC HYDROCARBON OF FROM 1 TO 30 CARBON ATOMS, AND MAY BE TAKEN TOGETHER WITH THE NITROGEN TO WHICH THEY ARE ATTACHED TO FORM A HETEROCYCLIC RING OF FROM 5 TO 7 ANNULAR MEMBERS.
A PETROLEUM DISTILLATE FUEL HAVING A BOILING RANGE WITHIN THE LIMITS OF ABOUT 250* F. AND ABOUT 700* F. WHICH HAS BEEN IMPROVED WITH RESPECT TO ITS LOW TEMPERATURE FLOW PROPERTIES BY ADDING THERETO: (A) ABOUT 0.05 TO 2.5 WT.
