if the olive oil goes bad use it as lantern oil. OO doesnt smoke up like other oils. i use it with lemon juice as furnture polish.
Great advice!
Part of my problem is I don’t know if I would recognize a rancid oil.
I guess I could compare the smell/taste to a freshly bought one.

Lehmans sells jars for olive oil (or other oils). If you want lamps it can be a viable option. Cheap too.
