F. to 1100.degree. F. and a viscosity in the range of about 50 SUS to about 600 SUS and an aromatics content in the range of about 20% to about 35% by volume with an aromatics saturation catalyst comprising noble metals on an inorganic oxide support at a temperature in the range of about 350.degree. F. to about 700.degree. F. and hydrogen at a partial pressure in the range of about 150 psig to 3500 psig to produce a dewaxed, dearomatized oil product having a significantly lower aromatics content than the dewaxed aromatics saturation reactor feed.
