Abstract
The invention relates to a method of making a PAO characterized by a low viscosity, low Noack volatility, and excellent cold temperature properties, using a promoter system comprising an alcohol and an ester. The products comprise trimers obtained by fractionating a hydrogenated bottoms product from an oligomerization process using said promoter system.
