Disclosed herein is a method for making diesel, gasoline and LPG comprising coprocessing a petroleum-derived feedstock with up to 50 wt. %, relative to the total weight of the feedstocks, of a lipid-containing feedstock in the presence of a catalyst under fluidized catalyst cracking conditions. Also disclosed herein is a method for making a diesel fuel or a combined diesel and gasoline fuel by injecting up to 50 wt. %, relative to the total weight of the feedstocks, of a lipid-containing feedstock to a stripper or a riser quench downstream from a petroleum derived feedstock injection point in a fluid catalytic cracking unit.
