Why is oil sold by the barrel instead of gallons or liters?

[@flamingchillum]

When they crack the oil at the oil refinery, they put 3 barrels in and 4 barrels of liquid comes out. What a scam. No tax on I/4 of your product........

Not sure how you get more out than you put in. Likely the other way around, that 4 barrels in gets you 3 barrels of fuel oils and the rest is heavier distillates and waste.

@@theeverydayengineer1 It is done inside the cracking tower. Long molecules are broken up to make the desire fuel types. This makes more drops and increases the size of the fluid inside the hi pressure cracking tower. Put 3 in and get 4 out....
