The Oil Storage units are Buildings that allow a larger maximum amount of Oil to be stored. There are currently six tiers of Oil Storage units that can be Crafted, with each increasing the maximum Oil storage available. Having more Oil allows you to run Mining Machinery at a rate higher than your Oil production rate, as well as use some Machines or Equipment that that require an up-front Oil cost, like the Rocket, Robot, Smelting Ores in the Furnace, and Burning Logs in the Foundry. To build higher tiers of Oil Storage, you must first have built all the previous tiers.
