A process for the preparation of oligomeric poly alpha-olefins comprises oligomerizing low molecular weight PAO in the presence of an ionic liquid catalyst under oligomerization conditions. The low molecular weight PAOs used as a feed or feed component of the present process are the light olefinic by-product fraction including the dimers and light fractions from the metallocene-catalyzed PAO oligomerization process.
