50 gallons of gasoline, or one barrel of oil.

I don’t believe you can get fifty gallons of gasolene
from a barrel of oil.

Any one know?

About 20 gallons of gasoline from a 42-gallon barrel of crude. The rest is other distillates. SOURCE

I’ve heard stories of oil wells in Texas that produced such light, sweet crude . . . oohhhh, crude . . . . that you could put it right into your gas tank, and a guy used to do so during WWII to get around rationing. But I’m not sure I believe it.

I know this one.

No - beacuse a barrel is 44 gallons.

A drum is 55 gallons.

I got one finally.

A barrel of crude oil is only 42 gallons in the first place, I think.

That is before it is refined into usable products.

[USFRIENDINVICTORIA]

As corkoman and ridesthemiles point out, a barrel of oil contains 42 gallons.

However, a refinery produces more than 42 gallons of product, for every barrel of crude oil. Maybe as much as 50 gallons total, depending on the crude and the processes involved. Most of this increase in volume comes from cracking large molecules, into smaller ones.

I'm not suggesting that the author actually knows what he's talking about — his blather about the energy content is pure gibberish.
