DEBRA'S ANSWER:

I don't know of a lamp oil that isn't toxic besides olive oil.

A number of years ago, I was writing catalog copy for a mail order catalog that sold olive oil lamps, so I know they burn.

Take a look at the olive oil lamp page on the Lehman's website. They have lamps for sale, materials to make your own lamps and a book called I Didn't Know Olive Oil Would Burn. So they could probably help you figure out how to get your olive oil lamp to work.
