What is the efficiency of converting crude oil to gasoline?

For example, the generation of electricty from a coal fired power station is about 31% efficient. Does anybody have any info on refining oil? Thanks

    Well yes and no…The cracking of the oil globule into chemical lights is not quite the same as burning a fuel to produce electricity and then calculating the proposed btu output against the actual output. Heres the reason…When oil is heated there is a point at which the odd shaped hydrocarbon molecule starts pulling itself apart ,,vibrating if you will, and resulting in (at that pressure and temperature ) a specific type of refined product..Like gasoline (naptha raw) . to get that fluid from the original combination one must invest quite a bit of energy..To rough that flow out though lets say for every barrel of oil you get 12% usable lights for napthat production ..the rest is Diesel , Motor Oil, and for all i know this is what my toothbrush is made of as well..so just to get us there it cost us 100$ per barrel and a barrel is about 50 gallons and we only get 12% return for gasoline (Naptha). So for that 100$ we only made 6 gallons of gas..at 3.00$ per gallon we only have 18dollars return..From a logistics point of view gasoline does not return as much as say Diesel which is easier to make and cheaper ..It sells for more than gasoline and compared to gasoline we use 50 times as much…So with the entire country moving freight on Diesel you can see why OIL folks want to make something that is cheaper and can be sold for more money…Back to your question though…the numerical efficiency of producing gasolinebased on monetary gain is 18%+/- 7%…..So the future is coming at a rapid rate lets get out there and find something else…Good luck from the E…
