Hydrocarbyl substituted carboxylic acylating agent derivative containing combinations, and fuels containing same
This patent describes a distillate fuel oil composition comprising a major amount of a normally liquid fuel and a pour-point depressant amount of: a copolymer of ethylene and vinyl acetate, the copolymer having about 30 to about 40% by weight vinyl acetate, a number average molecular weight in the range of about 1500 to about 3000, and about 3 to about 6 methyl terminating side branches per 100 methylene groups; and the reaction product of a hydrocarbyl-substituted succinic anhydride with a mixture of aminopropylmorpholine and diethylenetriamine, the hydrocarbyl substituent of the succinic anhydride being polymer of C/sub 15-18/ alpha-olefins, the number average molecular weight of the substituent being in the range of about 2000 to about 8000.
