How can i convert my outdoor wood furnance to burn used motor oil?

I don't know if I would reccomend it. Motor oil produces a lot of nasty, toxic, bad smelling stuff unless it is burned properly. IF you are sure it can be done, them I'm probably not the one to ask. A better option might be burning used cooking oil from restraunts, that's a lot cleaner burning.





In either case, you are probably going to need to reclaim some parts from an old, dedicated oil burning furnace. If you can find a working burner assembly, and rig up a filtering system it might work. Be sure it's vented properly, as there is always a risk of carbon monoxide poisoning.





Good luck with that....
