[ What is claimed is:] [1.] A method for upgrading hydrocracked feeds to produce lubricating oils which comprises:(a) contacting the hydrocracked feed under upgrading conditions of elevated temperature and pressure in the presence of hydrogen with a catalyst comprising a unitized powder pellet catalyst made by:(1) mixing powdered 10 member ring unidirectional pore inorganic oxide molecular sieve dewaxing catalyst with a powdered amorphous isomerization catalyst having an acidity of about 0.3 to about 2.5 wherein said acidity is determined by the ability of the isomerization catalyst to convert 2-methylpent-2-ene to 3-methylpent-2-ene and 4-methylpent-2-ene and is expressed as the mole ratio of 3-methylpent-2-ene and 4-methylpent-2-ene,(2) mixing the powdered materials together to form a homogeneous mass,(3) compressing/extruding the mass, and(4) pelleting the extruded/compressed mass.
