Abstract: The addition of alkyl salicylic acids and esters represented by Formula I (I) where R 1 = H or C 12 to C 22 linear alkyl group; R 2 = H or linear C 12 to C 22 carbonyl group; and R 3 = linear C 12 to C 22 alkyl group reduces the pour point of a hydrocarbon base oil. Thus, both a method for reducing the pour point of hydrocarbon oils and lubricating composition containing pour point reducing salicylates are provided. The hydrocarbon base oil in such method and composition preferably is a Group III base oil.
