Acceptable Ship Fuel

These items can be used to refuel the player's ship. They are loaded into the Fuel Hatch. Fuel is spent when traveling to other stars (travel within the system is free), and the cost is affected by discounts from Crew and Fuel Purifiers (discounts up to 99% are possible).

Purifiers reduce fuel cost by a flat amount, stacking up to 4 purifiers. They can be placed anywhere in the ship to gain their benefits.

Fuel cost reductions from crew stack infinitely, but have diminishing returns. For every new member with fuel cost reduction, all cost reductions from previously recruited crew members are reduced by half. For best results, only hire crew members with a higher fuel cost reduction than any current crew.

Trivia

 * In vanilla Starbound, only Erchius was valid fuel. Most types of fuel in FU can be produced without visiting the Moon, and some fuels (such as Hydrogen or Energiflower) can be easily automated.
