ABSTRACT (D# 80,943-F) A process is disclosed for preparing synthetic lubricant base stocks having improved properties. Synthetic lubricant base stocks may be prepared in good yield by oligomerizing linear olefins using certain acidic calcium montmorillonite clay catalysts. When a mixture of propylene and long-chain alpha-olefin is used, in which up to about 20 wt.% of the mixture comprises propylene, and the co-oligomers prepared therefrom are hydrogenated, a synthetic lubricant base stock having a lower pour point and a higher viscosity index is prepared.
