Abstract
The addition of a polyalkylmethacrylate having a weight average molecular weight of at least 600,000 has been found to be effective in reducing the pour point of a wax isomerate to a level that cannot be obtained with conventional pour point depressants. In a preferred embodiment, the wax isomerate is a slack wax isomerate.
