...this "waste oil" it seems to have the same list of "cures" ..or uses. I guess they just skip the carcinogens...
For as long as I can remember used motor oil, or (so called) "waste oil" has been used as a wood preservative out-on-the-farm... wooden shed floors, hay wagon boards, bridge planks, manure spreader floors, even the top of my shooting bench is protected from the elements with waste oil. It's used for starting fires, oil burning heaters, dust control, lubricating gate hinges and drive chains open to the elements on stationary machinery. Cut with a bit of kerosine, it works pretty good as a penetrating oil for loosening rusted parts.
Carcinogens? Yeah, probably not a good idea to drink the stuff, or swim in it... but I ain't gonna' do that. Out here in-the-sticks we don't "waste" anything, we were recycling decades before city dwelling tree-huggers ever thought of it... and now they have the gall to tell us we're not doing it correctly?? Well, I've got a couple words for them... but every time I use those words on AS I get sent to the "hole" for a few days.
