Oil refinery lvl 7

“Oil Refineries store your oil to keep it ready for use. They can also order oil shipments.”



  • Available in the Enlightenment Age, you can store your Oil here, and start to raid it from opposing Enlightenment Age+ players.
  • Note that Gunpowder Age players and below cannot steal your Oil. Don't let this discourage you from placing Oil Refinery inside your walls, as enemies that have purchased an Oil Refinery can easily steal your Oil.
  • Attackers can steal less than 10% of your Oil from the Oil Refinery.
