Clean distillate useful as a diesel fuel or diesel blending stock is produce d from Fischer-Tropsch wax by separating wax into heavier and lighter fraction s; further separating the lighter fraction and hydroisomerizing the heavier fraction and that portion of the light fraction below about 500 ~F. The isomerized product is blended with the untreated portion of the lighter fraction.
