I'm curious as to what the opinions are to this test having any relevance to actual engine wear? The opinions I've received from Mobil, Redline, Castrol, Havoline and BITOG is that it's a very misleading test that has no correlation to actual engine wear. For one, it's mainly for grease. The other issue I have with it is, according to Redline, their are many additives that you could add to an oil that would produce a great wear scar, but, would do nothing for your engine. So why spend the money on these additives? That was RL's take on it. It must fool alot of people though. However, I often wonder why other companies don't go after Amsoil on this test. Mobil claims it's an inexpensive test that has no significance at all.
