ABSTRACT:
Low pour point hydrocarbon oil compositions are prepared by incorporating in a hydrocarbon oil such as crude oil, gas oil, residual fuel oil, etc. about 0.01 to about 0.5 percent by weight of an oil-soluble alkylated polybenzyl polymer or copolymer with, for example styrene, the said polymer or copolymer having a molecular weight of about 500 to about 50,000 or more. The polymer or copolymer may be added, for example, as a hydrocarbon solution to the base hydrocarbon oil after which the final oil composition is formed by heating the components to 100.degree. to 350.degree. F. for one hour or more with mixing.
