Zusammenfassung:	A process for producing high quality lubricants by hydrocracking a high boiling hydrocarbon feed in the presence of hydrogen and a bifunctional hydrocracking catalyst based on an ultra-large pore crystalline material. The crystalline material exhibits unusually large pores of at least 13 .ANG. diameter and a high sorption capacity demonstrated by its benzene adsorption capacity of greater than 15 grams benzene/100 grams at 6.7 kPa (50 Torr) and 25 .degree.C. The crystalline material is characterized by an X-ray diffraction pattern with at least one d-spacing greater than 18 .ANG. and in a particularly preferred form, a hexagonal arrangement of pores of at least 13 .ANG. diameter which can be indexed with a d100 value greater ban 18 .ANG.. The hydrocracking catalysts based on these materials are capable of producing hydrocracked lobe products of good viscosity index in high yields without the use of fluorine or other promoters. Petroleum waxes may be used as the feed end is hydrocracked and hydroisomerized to form the lube products.
