- You must be playing a mod. There is no helium in the game.
- You are correct, France cannot buy fuel in the game. In fact, no nation can buy fuel in the game. Nations are expected to build refineries to increase their production of fuel and to build fuel silos to increase the capacity to store that fuel.
- France starts 1939 with 87K fuel.
- France does not start the 1939 game with any refineries, but does have a daily base fuel output of 48. This output will take France more than 5 years to reach max capacity of 348K.
- France can build a 1939 refinery in as little as 77 days (80% infrastructure state required) which will boost the daily fuel output to 97 (increase of 57). That will reduce the time to reach max capacity to a bit more than 2.1 years.
In my opinion, you should
not be training any ships, planes, tanks, or motorized. You should save all of your fuel for combat.
Do train the land divisions that
do not use fuel such as infantry.
As far as building refineries, I do not have any advice as I have not played France in a long time except for running tests. I ran a quick France test to confirm that the information stated above is correct. Perhaps other forum members will be willing to provide you with more guidance.
