[Christ]

Can you take some percent of your fuel pellets and soak them in the oils, then mix them back in with the bulk before delivery to the stove? That way, you're not introducing liquid fuels at all.

I suppose you could also (if you wanted to do it a more difficult way) use sawdust soaked in the oils, then press them into your own little pellets to be mixed in with your fuel pellets, or something like that.
