Yet I can't get through the checkout without seeing at least a couple people in front of me purchase a gallon or two. IMO, that would be the worst oil to use, though I have no experience trying it. Maybe they know something I don't!
Used oil makes great chain saw bar oil. I would never actually pay for the stuff though.
