Does anyone remember the oil additive demos from some years ago where they seized a bearing with a lever contraption, then dropped a bit of their snake oil on it and it wouldn't seize?
The claims were that you could put in in an engine run it, drain the oil and it would run without oil.
What happened to that show? I remember that they were at most every gun show.
I do remember a guy here that had a goldwing that he tested it on, ran it to operating temp, added an ounce or so and in about 20 min. the idle increased.
