Abstract
A polymeric substance, i.e. poly(isomerized C.sub.12 -C.sub.50 monoolefin), alone or as the alkylation derivative of an aromatic compound in combination with a lubricating oil pour depressant having pendant alkyl groups of 6 to 32 carbon atoms are useful in improving the cold flow properties of distillate hydrocarbon oils.
