Waxy distillates, or raffinates containing from as little as 10% wax but more typically about 30% wax or more are upgraded by a process comprising the steps of hydrotreating the waxy oil under conditions which convert less than 20% of the feed into products boiling lower than the feed to reduce the sulfur and nitrogen content of the oil followed by hydroisomeri- zing the hydrotreated waxy oil to reduce the wax content and increase the viscosity index. This oil having a waxy content of less than 30%, preferably less than 25%, can now be more easily dewaxed using conventional solvent dewaxing procedures. The advan- tage of the present process resides in the increased yield and/or stability of oil as compared to other upgrading, dewaxing processes which convert wax to light products. The isomerization catalyst is preferably a low fluorine content catalyst, more preferably a noble metal on 0.1 to less than 2 wt% fluorine on alumina catalyst, most preferably a noble Group VIII metal (e.g. Pt or Pd) on low fluorine content (less than 2 wt% fluorine) on small particle size alumina (less than 1/16 inch diameter) catalyst. The most preferred alumina support is a 1/20 inch trilobe.
