Oil
Oil is a resource that can be found after you reach the Underground City.
You can extract Oil using the Oil Pump found at the middle below the Pyramid in the Underground City.
It can also be obtained from Treasure Chests (reward is 1 hour of Oil production, or 4 hours from golden chests) or as a reward from scientific excavation mission (reward is 25% of the Oil cap). For the exact amount of obtained Oil look at the table on Oil Pump.
When your Oil Pump is full it will stop working. After this, chests will stop dropping Oil and Scientist will stop receiving the "Some Oil" mission. However, you can collect either a chest, an excavation or both that get you over capacity. You can try to use this to your benefit to buy some blueprints requiring more Oil than your current cap without needing to upgrade.
- Maximum overcapacity
The maximum possible theoretical overcapacity of oil would be 175% + 4h production. For this you would need to get a Golden Chest giving Oil (only 3.5% chance, and only if your Oil Rig is not already full) just before being full, + 3 scientist excavations, all giving Oil, which in turn would have to be activated while the capacity wasn't full. That's why in practical terms, 125% is the maximum everyday limit.
Oil is used for[]
Oil is used as a material to upgrade the Drill starting at level 12 and to upgrade weapons in the Underground City. Unlike other materials, Oil can't be sold.
