This patent describes a method for upgrading increasing conversion to liquid products of a residual oil portion of crude oil boiling above 600{degrees} F. It comprises metallo-organic compounds which comprises contacting a feed containing the residual portion of crude oil boiling above 600{degrees} F. The feed having a Conradson carbon content above about 2.5 weight percent with a catalyst consisting of from 20 to 80 wt. % of an ultrastable faujasite crystalline zeolite dispersed in a silica-clay matrix for a time at a temperature particularly selective for conversion of the residual portion of crude oil to products of gasoline, light cycle oil and gasoline forming gaseous components, and recovering the products comprising gasoline and light cycle oil selected from the group consisting of: silica-clay, silica-alumina, clay, silica, alumina and mixtures thereof, at a temperature above about 950{degrees} F. to provide a ratio of volume percent of light cycle oil to heavy cycle oil of in excess of 1.03 at essentially constant conversion and recover the light cycle oil and heavy cycle oil.
