In HOI3 we converted Energy into Oil even if you were a minor, yet only 3 countries that I know of really built synthetic rubber facilities, and only Germany built synthetic oil factories.
To better represent this problem I think it would be best if this were added as Factory lines the way we produce equipment so that minors and other nations simply aren't just getting free resources.
Add in 2 Techs:
1 for Synthetic Oil creation
a. First tech unlockable in 1920, with several upgrades through 1950
1 for Synthetic Rubber creation
a. First Tech unlockable in 1940 with a few upgrades through 1950.
Synthetic Oil factories would create Oil from nothing (Coal is not represented in the game).
Synthetic Rubber Factories would create Rubber from oil at some ratio (like 2 oil input = 1 rubber).
The factories would work the way other factories work, except they could get to 100% efficiency very quickly as they are producing several units each per week.
This would force these countries to either focus on capturing oil regions (Japan capturing south Asia, Germany/Italy Capturing Middle East) or to devote some of your precious industry to creating these resources as the countries did in real life.
Since factories represent everything that is abstracted about the economy, Germany and Italy would not need to devote the resources to develop these factories if they capture and hold the middle east, allowing more manpower and investment to war production. It also means that the UK would need to spend considerable more amount of resources defending South Asia and the Middle East, otherwise they will need to develop these technologies and devote industry to them.
