I-petroli yinto enokutsha kakhulu, ebonakalayo, elula kakhulu, ephuzi, eneoli enevumba elimnandi, efunyenwe kwi- distillation yeoli ekrwada kumaqondo obushushu aphakathi kwe-35 kunye ne 215 °C [1] . Kwilitha yeoli, kuphela i-10% eba yipetroli emva kwedistillation yokuqala elula. Ukusebenzisa amaqhezu anzima (i-diesel enzima kunye ne-distillation residues) kunokwenzeka ukufumana iamolekyu ezincinci ezifanelekileyo ukusetyenziswa njengepetroli, ngenxa yonyango olubizwa ngokuba yi -catalytic cracking, apho i-hydrocarbons yobunzima obukhulu be -molecular iyahlukana phambi kobukho be- catalyst .

Kwi- European Union kude kube yi-2000, unyaka wokuvinjelwa kokusetyenziswa kwe -lead compounds njenge-anti-knock agents, yongezwa kunye ne -tetraethyl lead . Emva koko, i-petroli engenalothe yachongwa ngegama lepetroli eluhlaza, enombala oluhlaza ngokongeza i-pigments ethile.
