Clearly, you know nothing about the oil trade. Unless you're selling retail or private-to-private (typically more expensive unless they're right next door), there's no way of selling large quantities of oil in any other currency.

You can use your ducts-and-tubes-machine and check it out.

And you should stop thinking and starting learning the facts. Anyone can fart or "think". And some confuse the two when they have no knowledge of the facts.
