FIELD: petroleum industry. SUBSTANCE: method involves regulation of raw final temperature point in cracking process. Its residual fraction is fed to producing the basic oil components. Method involves change of amount of hydrocracking residual fraction recirculating part also. Method provides producing maximal amount of oil basic components depending on requirement change with respect to light or heavy oil basic component. EFFECT: improved method of producing. 1 tbl
