Reynolds, J W; Brinkman, D

Five new lubricating oils of the extended drain and/or friction modified-type were charged to vehicles and used. The segregated drainings from each oil were re-refined by the solvent treatment/distillation process developed by the Bartlesville Energy Technology Center. The solvent treatment step of this process failed to desludge these oils significantly, indicating high levels of active dispersant additives remaining in the oils because of insufficient use. The overall process was successful, however, in producing re-refined basestocks of apparent high quality from the used oils. Thus, it would appear that direct distillation without pretreatment would have been adequate for these segregated samples.
