Way back when..when Slick 50 first came on the market...a buddy and I were at the Tri State Fair. A guy had a demo set up where he had a little straight 6 running and by turning a couple of pet cocks he could drain the oil from the pan and put it in a tank while the engine was still running.

The engine would still run, but the lifters would be knocking like mad.

The demo had a sign that said, 'This Engine Runs With NO OIL!".

My buddy walks right up to the guy (not knowing the gist of the demo) and tells him, "Yeah buddy, no kidding it doesn't have any oil! Every lifter in the thing is knocking!".

Then the guy opens the valves and let the oil pressure come back up.

We had a good laugh about that later on...not a diss or endorsement of Slick 50, just a story.
