I think Oil use should go up by 4-5x what it normally is, or have certain units (like jets) use more oil than troops or tanks. You have a government that is focused on Oil making. However, you will never see a Oiler being able to make top 10 or even top 50, even if they converted to Demo or Theo to resell. Even if you were one of the only oilers, you still wouldn't be able to do it.

Someone suggested using oil to explore. This is an interesting idea, but it would mean we need to start with oil on our countries to do the first batch of exploring.

I also suggest being able to FA oil to other countries. Just because... it can help them hit... or something... yeah...

You may be able to have PS use more oil than a SS, or more oil for a BR instead of GS.
