So the need for oil drill and marketing genius greatly falls away. Refinement is another matter however.
Well, I'm not really sure about that. They did use oil lamps, but I think they used olive oil or other non-petrol oils. I don't think that you would get a proper explosion using such oils. If you could, then they would not be safe to use for oil lamps. But that's just my guess.
