I just had my second Oil Crisis event.
After the first one, I have prepared by building two large tanks far away that should contain enough fuel to get through the crisis.
I have four small stands and a small fuel depot next to them.
I have not found any way to tell the small fuel depot not to ask for delivery once its empty. My tanker trucks should go to the far depot for refill. If I cancel the contract, my fuel sales cease as well because having a fuel contract is a prerequisite.
How can I stop buying fuel and just use up what I have?
