Could you add that the fuel speed bonus increases the speed of the machines? There is a separate mod for it, but it seems to not wok. Burner Everytjing++ does it also, but your mod sounds like a more future proof version that can also be used with other mods.

Short answer, no. The way Burner Everything++ and other similar mods do it is to have a copy of each entity for each fuel value, and check every tick to see if the fuel has changed. That, or have a separate internal beacon modifying the speed of each machine. In either case, it drastically reduces the UPS of any save it is applied to. If the Factorio devs decide to implement this as an engine feature (see link below) the I will definitely update this mod to include it.

Respond to the forum post below so more people see it. Post it on discord if you want to spread the word at all.

That's fair.
Another question, Burner Everything has smoke coming of all buildings, that's a nice touch.
Is that a thing you could add? I'd prefer using your mod.

Yes, i believe smoke was on my todo list
