Sorry, it is me again. I must be dumb... haha because I still cant select other liquid or fluid to be used as fuel.
I am using bob's Angel's mods.
At the start of the game, appear this message:
Reset road network - Elapsed: 8.014000ms
Transport Drones: "petroleum gas" is not a fluid, so drones are using [Fluid: Methane gas] Methane gas as fuel instead. Set "Transport drone fuel" in the startup mod settings to a fluid's internal name, such as light-oil.
I try to write Hydrogen-gas, doesnt work, I try Methanol-gas, also not... haha
