Accurate figures are hard to come by, but my best estimate is that diesel cars account for around 50% of the car market at present and that share is increasing. Some time ago I read an article about the contents of a barrel of oil and the figures are as follows:
|distillate fuel oil (Includes home heating oil and diesel fuel)||9.2||20.81%|
|kerosene-type jet fuel||4.1||9.28%|
|residual fuel oil (Heavy oils used as fuels in industry,
marine transportation and for electric power generation)
|liquefied refinery gasses||1.9||4.30%|
|asphalt and road oil||1.3||2.94%|
Discounting the differences in fuel consumption between the two engine types I think that there is a glaring anomaly here. We are producing twice as much petrol as diesel for the same number of vehicles of each type, so the question is: How is it accounted for, where is all the surplus petrol going?
I understand that there are far too many variables to grapple with, and that a barrel of oil varies in consistency and content depending on its geographical area of production but I don’t understand why there is no information available for the discrepancies. Note also that the “Distillate Fuel Oil” covers heating oils too, so there is a bigger difference.
Over time I have remarked upon this to various people but no credible answer has been given…. Can you help?
