Is it possible to change the setting to use solid fuel? I see in startup settings there is option for that, but it doesn't seem to work. I'm using space exploration mod that has processed fuel entity and it would be a good fit for transport drones.
When I change that setting to use "processed-fuel" fuel depot is still looking for petroleum.

You can only use fluids, not solid items.

@Andrew : what option were you talking about ? i only see mod options to change the amount of fuel and the pollution (in startup settings) and the interval (in map settings), but none for the type of fuel.

@Klonan : but speaking of these options, two old changelog entries said

Version: 0.5.13, Date: 2020-05-02
Added settings for fluid capacity, fuel type, fuel capacity, fuel consumption, and pollution.

where are these options ? i can only see "fluid capacity", "Pollution", and "Update Interval"
have they been removed since? or did maybe some other mod (for steam) remove them ?

Version: 0.5.14, Date: 2020-05-03
- Changed fluid per drone settings minimum to 0. Setting it to 0 will basically mean you don't need any fuel.

when i tried setting this to 0 in the newest version 0.6.x,
it was an illegal value out of range (min 1, default 500, max 10000)

or is this a misunderstanding because of mixing up "fluid capacity" and "fuel capacity" ?

Are you using another mod which is hiding the settings?

Set fuel per drone and fuel usage to 0 and it will work

i just looked at the settings.lua of steam drones, and it sets several options and also adds "hidden = true" :-(

since i upgraded from an older version to the newer version of this mod that had this option before reading the changelog, and at the same time also installed the steam option to get rid of the petrol requirement, i wasn't aware of the nice new options.

i also have no idea (yet) what the steam drones mod might additionally do that this mod with the above options can't do. maybe i can simply drop the steam mod and set everything myself in these options for this mod only.

in the screenshot you showed "fuel consumption per meter" ... is that assuming 1 meter = 1 tile ?
and with "fuel per drone = 50" and "fuel consumption = 0", does it require to have fuel which then is not used ?

With 0 fuel consumption they will still take the refund fuel, just not consume any after their job

If you set the Transport Drone Fuel per drone to 0, and the consumption to 0, then they will take and use no fuel.

You can also just set the fuel fluid to something like water with the mod setting

What should I write in the field "Fuel" so that drones use diesel?

I am playing with Pyanodon modpack and i have set the fuel type to Gasoline, but in game the fuel depot still only take petrolum gas, tried changing it to water and it work, but Water doesnt work.

i have discovered that if you use capital letter when changing fuel type it wont work.

I think you should use "flued-name" in game. press F4 -> debug -> select show-debug-info-in-tooltips -> press F5 -> move mouse on flued, and see "flued-name". water is "water", not Water, also py's Coal gas is "coal-gas", Gasoline is "gasoline".

ok yeah i got it, gota select it from the menu not on a pipe on ground
