Its rare that i run out of oil.
But it happens.Especially when i take over a huge region like China or India while playing a small region like Japan.
One miscalulation and its easy to find oneself in a large oil/fuel deficit.
Now heres what i did today, that i found rather interesting.
I used supply vehicles to convert supplies back into fuel/oil.
I had just issued orders for 20+ hex advance (into Pakistan) by circa 100+ units.Than India fell to me creating a huge oil shortage, which means a huge fuel shortage.
Now the supply system automatically provides fuel and supplies, BUT only some units allow the supplies to become fuel.
So by simply setting up roving supply vehicles i was able to convert some of my huge stock pile of supplies back into fuel, and finish the 20+ hex advance for all 100+ units despite having a 15million barrel of oil deficit .
Now doesnt this mean, that i was able to turn non-fuel products into fuel ?
Military goods consist of Ore, Petrol,Industrial Goods and Electricity.
Military goods = supplies.
Supplies convert to fuel as needed.
BUT when military goods in the form of supplies are used as fuel it seems to be a one per one conversion.Which means im somehow managing to turn ammo,spare parts, etc... into usable fuel
Which means, if you can buy military goods(or have a huge stock pile),you dont need oil for your armies
Its something i never thought of til i had to solve the issue i ran into today.
