Rocket Fuel is vital to running your Spaceship.
To craft Rocket Fuel, you will first need to craft an empty Fuel Canister. Then, you will have to find some Oil. Use a Portable Oil Extractor to get enough oil to fill up the canister. Now you will have to create a Refinery to refine the oil into usable fuel.
How To Use Rocket Fuel
In order to launch the Rocket, you must insert a charged Battery into the Fuel Loader, or attach it to a Coal Generator and the Rocket Launch Pad. If done correctly, the Fuel will start loading into the Spaceship. After the Fuel has fully loaded into the Spaceship, the player can launch out of the atmosphere.
