cr1- actually,when they first came out with STP oil treatment the salesman would go around demonstrating how to put a 1 inch pin in a 1 inch hole. They had a devise that measured how many tons of pressure it took to do it dry, and then showed how much less it took to do it when lubricated with STP.

A piece of metal that is machined perfectly flat will slid across the surface of another piece of metal even though there is precisely zero space between them. It’s the same concept with a peg in a hole. There doesn’t have to be any space, you just have to overcome the friction.

Of course one may argue that there has to be at least enough space on a microscopic level for the oil molecules to fit between the surfaces…
