Abstract of the Disclosure Process oil is made by conversion from "waste" materials, particularly used oils, and most particularly used crankcase oils, by flash evaporation at about 250°F and filtration for removal of solids therefrom, to produce a product substantially free of water and low boiling point components and of contaminant solids, which has a flash point above 310°F, or is blended with other products from the same process to produce a final product having a flash point above 310°F, and an aro- matic content above 10%, preferably above 20%, by weight. The product may be used generally in a wide variety of process oil applications but is most par ticularly adapted for use as a rubber process oil and such use is also part of the present invention.
