In Supremacy 1914, oil is produced by establishing oil wells in regions that contain oil resources. To do this, you need to secure territories with oil deposits, typically found in specific provinces, and then build the necessary infrastructure to extract and refine the oil. Managing your economy effectively and ensuring a steady supply of resources will help you maximize oil production for military and industrial use. Additionally, you can trade for oil if your territories lack sufficient resources.
