Abstract
Bicyclic and monocyclic terpenes are oligomerized by contact over a zeolite catalyst to produce high boiling lube oil traction fluid having a high traction coefficient. The traction fluid comprises dimers, trimers and tetramers of the bicyclic and monocyclic terpenes. The lube oil is catalytically hydrogenated to obtain a saturated cycloparaffin hydrocarbon oil traction fluid.
