A method for hydroprocessing a hydrocarbon synthesis product feed to form upgraded fuels and lubricating oils. In a preferred embodiment, the method includes the steps of: (a) contacting a Fischer-Tropsch product with a hydroprocessing catalyst to produce a desired distillate; and (b) counter-currently stripping the desired distillate as it is produced. The method may include distilling the desired distillate or distilling the treated Fischer-Tropsch product.
