A method for making an alkyl cyclobutane fuel, which includes obtaining a solution of at least one alpha olefin. A catalyst is added to the solution, thereby generating a mixture of dimers. The mixture is hydrogenated, thereby converting the dimers to hydrogenated dimers. The mixture is purified to produce an alkyl cyclobutane fuel.

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.
