Lighten up Francis...
Wow has a plan that he's put some thought into, and while I don't personally use WMO for anything except the occasional bonfire starter, and only consume a small amount of bar oil. So it would never be cost effective. But still I see a lot of merit in his concoction. I think the amount of bar oil making it's way into the lungs are minimal, at best. And "known carcinogen"? Did the regular bar oil get a free pass on that? Or is it more okay for breathing? I change my oil when it turns caramel colored, and would assume that it would take little filtering to once again be useful. But fully agree that bar oil is cheap, so that's what I use.
