The production system penalizes output efficiency if you're short on a resource, but doesn't stop production. That means Germany or Italy can run with ZERO oil supplies for the entire war, but their output of units which require fuel will be severely reduced.
This is what I'm scared about. I'm scared that oil will not be this make-or-break, essential resource that was in the actual war, but just something that's nice to have but not necessary.
Honestly, there should be extreme production penalties, if you just can't outright produce stuff, if you have an oil shortage. Even then, the system is just stupid. For ships it assumes the ship will last for a long time, when in reality the ship could be destroyed in a few days and then the oil reserves used to make it just disappear. What a silly oversight.
With tanks and planes, as long as your units don't get damaged, they will essentially run on magic fairy dust since you don't have to replace said units with newer ones, which were made with oil.
What they should do is make units relatively cheap oil wise, and require units that logically needed oil (things like tanks, planes, ships, mechanized, etc.) to consume some amount of oil when moving from province to province.
