Johnpr3 & Jonny-b; While you got a good laugh out of polytron's video featuring destructive testing I only viewed number results from TUV's pages. How does TUV test for wear? I have a machine similar to the one in our video that I use to seize bearing material with a wide range of engine oils. You would be surprised which engine oils do not stand up to wear criteria.
Actually on a destructive test none of them do. There are some engine oils like Royal Purple that will not seize the race bearing at all but not without substantial damage to the test bearing. I enclose 2 pics of bearings of which the 1st was seized at 450 Inch pounds of torque and the resulting damage. The second picture is the result of adding polytron metal treatment to the same oil as the 1st picture. A force of 1200 inch pounds was applied to the same bearing that was flipped over and did not seize. The test engine oil was Mobil 1 synthetic. The promises of Nanovit & Polytron are similar, achieved in different ways. I have tested other prominent additives. They don't work.
jonny-b;
after looking quite hard I found that they probably use a pin to disk tribometer. Tribometer is defined as any instrument used to determine friction in 2 moving bodies. Ok, our instrument doesn't cost $20,000 but does effectively demonstrate oil lubricity in 2 mated metal surfaces. I suspect that visual results aren't visual convincing because of the nature of the test and the not so honest nature of many people out there. I bought a machine to convince myself of the truthfulness of this product. I am still impressded with the results and consequently have used these products in my vehicles and around my home for 3 years. by the way did my pics show up as an attachment?
