== When to use Solid Fuel as fuel ==
Solid fuel is also obtained from recycling [[scrap]]{{SA}}, which can be mined on [[Fulgora]]{{SA}}.


Coal and Solid Fuel production can both be automated, but each has advantages and disadvantages. Solid Fuel is made from oil, and oil supplies are theoretically infinite, since oil spots never run completely dry.  However, coal is almost always used first, and if coal is plentiful on the map, it may not be worth it to switch systems over to an oil infrastructure just for fuel.
== History ==
 
{{History|2.0.24|
0.15 has changed all this, since now Solid Fuel gives vehicles greater acceleration and top speed. Also Coal Liquefaction is now available, giving the ability to turn coal into oil.
* Solid fuel from ammonia cost and crafting time reduced: 6 crude oil instead of 20, 15 ammonia instead of 50, and 0.5 seconds instead of 1 second.
 
}}
One unit of Solid Fuel has 25MJ of energy, over three times the energy value of coal.


== Which Solid Fuel recipe to use ==
{{History|2.0.7|
* [[Light Oil]] has the best oil to Solid Fuel ratio (10:1), and has little other in-game use, making it the best choice.
* Decreased the crafting time of solid fuel from 2 to 1.
* [[Heavy Oil]] has a much worse ratio (20:1) and should be cracked into Light Oil first instead.  The cracking process changes the ratio for Heavy Oil to 13:1, which is much better.
}}
* [[Petroleum Gas]] also has a bad 20:1 ratio and should not be used to create solid fuel in most cases.


However, full tanks of Heavy Oil, Light Oil, or Petroleum Gas can back up and block the Oil Refinery from refining more Crude Oil. This can create a situation where, for example, you can't create Petroleum Gas because your Heavy Oil tanks are full. It's advisable to set up some Solid Fuel factories to relieve the pressure in cases like this, particularly once [[Circuit network]]s have been researched and the factories can be switched on automatically once liquid levels reach a certain amount.

Solid fuel is a kind of fuel and is processed in a chemical plant. One unit of solid fuel contains 12MJ of energy, three times the energy value of coal.

Besides being useful as fuel in all burner devices, solid fuel is also used to produce rocket fuel, which is a component of rocket parts built in the rocket silo.

Recipes

Solid Fuel can be created from heavy oil, light oil or petroleum gas. Light oil has the best oil to solid fuel ratio (10:1). Cracking heavy oil to light oil first changes the ratio for heavy oil to 13:1 (from 20:1).

On Aquilo, the ammonia recipe is by far the most efficient. With no productivity bonus, optimally converting the products of advanced oil processing to solid fuel will result in needing approximately 10.55 crude oil per solid fuel, whereas solid fuel from ammonia needs only 6 crude oil per solid fuel.
