this would be a tech question, kind of. does anyone know how many gallons of gas can be produced from a barrel of oil ? and also is a barrel of oil being considered 55 gallons or something different ? ,
ok i found this, http://www.energy.ca.gov/gasoline/wh...arrel_oil.html
if i am reading it right 51.4 % fuel means around 21 gallons of gas.
