My cousin sent me a copy of a cliping, from where i don't know. it was a question - answer forum. Question: How many gallons of gas does a barrel [42 gallons ] of crude oil produce? It had a name and then the answer ; About 20 gallons. this same barrel also produces 10 gallons of diesel and heating oil [combined ] and 5 gallons of jet fuel plus other products. It was interesting but is it true? Anyone have that knowledge? Robert
