There used to be a vender that showed up at the Hot August Nights swap meet too sell an oil additive. He had a demo engine with the pan removed to show there was no oil "only the treatment with his product". The engine ran all day, day after day at idle. It had water. The engine of choice was a 250. I was always temped to give the throttle a twist.
That had to be some really good additive. I do add ZDDP with my oil, but his stuff muet be pretty good!
Oh man. If you would have twisted the throttle, well that would have gotten interesting. LOL
