Sorted by relative score. Higher scores deliver more output per coin for your chosen balance.
Duration is converted into minutes, multiplied by the fuel boost, and divided by cost (with diminishing penalty) to create a comparable score. Infinite fuels receive a large baseline duration so they remain competitive when uptime matters.
Need deterministic production? Aim for higher duration priority so fuels like Everburning Flame rise to the top. Looking for burst mining sessions? Push the speed slider toward 100% to prioritise Catalysts or Hyper Catalysts.
