    • A process is disclosed for the production of high quality synthetic lubricants which comprises transforming ethylene into a mix of alpha olefins, separating from this mix of alpha olefins the alpha olefins in the range from about 14 to 20 carbon atoms, oligomerizing the alpha olefins in the range from about 14 to 20 atoms with a perfluorosulfonic acid resin catalyst and hydrogenating these oligomerized olefins. The olefins from the original mix of alpha olefins which are lighter and heavier than the 14 to 20 carbon atom alpha olefins processed above are combined and subjected to an isomerization/disproportionation process and the resulting olefins in the range of about 14 to 20 carbon atoms are oligomerized with perfluorosulfonic acid resin catalyst as above. Optionally, these olefins in the range of 14 to 20 carbon atoms may be combined with the olefins prepared directly from ethylene before oligomerization takes place. The resulting oligomers are hydrogenated. The olefins from the isomerization/disproportionation process which are less than 14 carbon atoms or greater than 20 carbon atoms are once again subjected to the isomerization/disproportionation process as above, the 14 to 20 carbon atom cut is oligomerized, and the process is repeated. The resulting hydrogenated oligomerized olefins are useful in internal combustion engines as crankcase lubricants.
