Making Oil
To Make Oil, you must do the following:
1. Collect 1 swamp tar for each lantern you wish to add oil to.
2. Take all the swamp tar, and all the lanterns you wish to add oil to to the chemist in Rimmington.
3. In the middle of the chemist's house, there is an Oil Still. Use the swamp tar on the Oil Still.
4. Use your lantern on the oil still, and it will be filled with oil.
When a lantern is lit, you can extinguish it by using the extinguish option on the lantern when lit. Once you have added oil, it never needs to be added again.
