ABSTRACT OF THE DISCLOSURE There are disclosed a process for producing an oligomer by oligomerizing a raw material comprising an unsaturated bicyclo heptane derivative and/or an unsaturated bicyclo octane derivative, which comprises the step of restricting the contents of dienes contained in the raw material to at most 1% by weight; and a process wherein the raw material is subjected to solid acid treatment simultaneously with or prior to distillation and then to oligomerization. The above process can efficiently produce the oligomer well suited for use in a traction drive fluid having a low viscosity and exhibiting excellent performance over a wide temperature range.
