Abstract:
The present invention relates to a lubricant composition for a process for reducing the paraffin content of mineral oil compositions, by providing a mineral oil composition with a dewaxing aid, cooling to form a paraffin precipitate and at least partly removing the paraffin precipitate formed. The dewaxing aid used is a copolymer mixture comprising at least three copolymers, the copolymers differing in the composition of the repeat units.
