How do I add oil?!

Once you have made some molten glass, take your glassblowing pipe and use them together in order to open the glass Crafting menu. Select glass lens to make a glass lens for the bullseye lantern. This light source requires the use of oil as a fuel. Use the glass lens with a steel bullseye lantern. A bullseye lantern can be made by Smithing one steel bar. See the Smithing Skill guide for full instructions how to smith a bullseye lantern. To light the bullseye lantern, simply add oil and then use a tinderbox on it to get the flame started.

Well how do I get oil?

I think you have to distill it, no?

Just buy unfinished bullseye lanterns and light them. That's what I did.
