the description says:

To produce 50 liters of crude oil you need 1 piece of coal, 5 pieces of raw wood, 10 liter of lubricant & 100 liters of water.

this would allow to make oil from coal and wood in a world that has no oil, but only IF i can get lubricant somehow before making the first oil with this recipe ...

and the description also says:

A recipe to create coal from trees is also added. 6 Wood = 3 Coal.

this would allow to make coal from wood, and thus make oil from only wood in a world that has neither oil nor coal, but the problem still exists: i need to get lubricant somehow before making the first oil ...

it would be nice to have some option to use these recipes without needing lubricant,
or to have an additional recipe that can make some kind of lubricant, only from wood and coal.
