I've worked in shops with commercially produced ones. There are
regulatory requirements to deal with; the federal ones are pretty
easy: they assume that if the fuel is okay, the exhaust will be, too.
They do limit you to burning waste you generate yourself. Used oil is
about 140K BTU/gallon, so unless you've got a lot of equipment, you're
not likely to generate enough oil for it to be worthwhile. States
and cities have tougher rules, and may prohibit them residential
areas.
I wouldn't even think about a stove that mother earth news says you
can build. It's unlikely to be a safe design, and it certainly won't
be efficient.
