Well you don't just burn used motor oil in a furnace without
treating/filtering it anyway. At least you don't if you know what's good
for
you. Used motor oil is contaminated with all sorts of things, cadmium for
example (from bearings) which is bad for you when you get it into your
system. (This is why garages/service stations stopped burning motor oil
for
supplemental heating. There used to be quite a market for stoves to burn
used motor oil.)

You burn the untreated oil, the contaminating products get into the air,
you
breath the air, or touch a contaminated surface, eat something that has
been
grown in contaminated soil in your garden, and wonder why you die or your
children are born with two heads etc..

This sounds like alarmist thinking to me.
The EPA allows burning a waste motor oil for heat as an accepted way to
dispose
of it.

Mother Earth News thinks it's a good idea also:
