I don't know about the tests etc. but I stopped at a friends gun shop and he showed me the lucas oil stabilizer. He used it as a cutting oil. He chucked up a piece of 3/8 mild steel in the drill press and put a few drops of Lucas on a piece of steel plate. I put a lot of pressure on the thing spinning in the Lucas. It resulted in no heat, the same thing with motor oil would burn you. STP would not keep it cool, the same hot as oil. I know what I saw, more than snake oil.
