A process for converting hydrocarbon oils into relatively lower boiling hydrocarbon oil suitable for use as motor fuel comprises distilling petroleum oils including a virgin crude petroleum oil in a preliminary fractionating zone to produce a residual oil and a fractional condensate higher boiling than naphtha, separating some sludge from the residual oil, and heating the residual oil free from thus separated sludge in the presence of steam under cracking conditions of temperature and pressure. The fractional condensate is heated under cracking conditions selectively different from those imposed on the residual oil and effective for converting a substantial part of the fractional condensate constituents into gasoline hydrocarbons. The vapor products of the thus treated fractional condensate are fractionated in a secondary fractionating zone to separate and condense a substantially tar-free heavy oil fraction higher boiling than naphtha. Hot products from the heat treatment of the residual oil and substantially tar free heavy oil fractional condensate from the secondary fractionating zone are passed into the preliminary fractionating zone to form part of the petroleum oils subjected to distillation therein.
