I try use fuel oil, i try to convert it to Light oil, but it not produce any steam at all and did not consume fuel.

It have oil and water but no steam in pipes in output.

Same thing with Oil butner generator, it did not consume fuel even if i place it in isolated electric network.

You must actually convert Fuel Oil in to Liquid Fuel, i think this must be added in discription

Fuel oil isn't actually part of bob's mods. My mods do add liquid fuel, but the oil burning boiler (and pretty much anything else oil powered) simply burn and fluid with a fuel value.

if the fuel oil doesn't have a fuel value, that's not my error, since I don't add it to the game.

do you know what mod does?
