This invention is to a method of oligomerizing an olefin feed stream. The olefin feed stream contains at least one C.sub.2 to C.sub.12 olefin to obtain an olefin feed stream and has less than 1,000 ppm by weight oxygenated hydrocarbon. The olefin is oligomerized by contacting with an acid based oligomerization catalyst.
