Additive concentrates for distillate fuels
This patent describes an additive concentrate for incorporation into wax containing petroleum fuel oil compositions to improve low temperature flow properties. This additive consists of an oil solution containing about 20 to 70 wt. % diluent oil, and 30 to 80 wt. % of an additive combination of: 1.) one part be weight of a C/sub 30/-C/sub 300/ oil-soluble diamide; 2.) in the range of about 0.005 to 1.0 parts by weight of an oil soluble organic acid of 6 to 30 carbon atoms, and one to three acid groups, 3.) in the range of about 0.01 to 10 parts by weight of an oil-soluble ethylene backbone distillate flow improving polymer having a number average molecular weight in the range of about 500 to 50,000 which is a copolymer consisting essentially of 3 to 40 molar proportions of ethylene per molar proportion of unsaturated ester; 4.) and the organic acid lowers the viscosity of the oil containing (1) and (3).
