The Birch Jerrycan is a Common Fuel Canister in Unturned 3. It is used to fuel vehicles and Generators.
When the Birch Jerrycan contains fuel, it can be used to fuel an object. When used to refill an object, the Birch Jerrycan is emptied and needs to be refilled at a Gas Tank or at a Gas Pump located at various places around the map. Every Birch Jerrycan spawns empty, so the Player needs to refuel it when they have it.
