A system and methods for manufacturing a base oil stock from a light hydrocarbon stream are provided. An example method includes cracking a light hydrocarbon stream to form an impure olefinic stream, separating water from the impure olefinic stream, and oligomerizing the impure olefinic stream to form a raw oligomer stream. A light olefinic stream from the raw oligomer stream and linear alpha olefins are recovered from the light olefinic stream. A heavy olefinic stream is distilled from the raw oligomer stream and hydro-processed to form a hydro-processed stream. They hydro-processed stream is distilled to form the base oil stock.

Provided herein is a unique process that prepares a saturated hydrocarbon mixture with well-controlled structural characteristics that address the performance requirements driven by the stricter environmental and fuel economy regulations for automotive engine oils. The process allows for the branching characteristics of the hydrocarbon molecules to be controlled so as to consistently provide a composition that has a surprising CCS viscosity at −35° C. (ASTM D5329) and Noack volatility (ASTM D5800) relationship. The process comprises providing a specific olefinic feedstock, oligomerizing in the presence of a BF.sub.3 catalyst, and hydroisomerizing in the presence of a noble-metal impregnated, 10-member ring zeolite catalyst.
