You are right Lou it is interesting. Wow, we have a tendency these days to turn everything into a competition that has to have a clear "winner"! Even if 10th place would work fine. My take on this to me is that it confirms that there isn't really that much practical difference in quality oils until you apply extreme conditions a normal engine wouldn't experience (i.e an oil temp of 425 F! If your engine oil gets any where near that hot in your tractor you should be worried about a heck of a lot more than just your engine oil!), and even in the out of normal circumstances the differences in oil aren't that great. The lubricity test results seem to me to be statistically insignificant unless multiple tests were run. I learned in school that lubricity (friction reduction) and wear are separate and independent attributes of oil. As an example, STP oil additive has been found to greatly reduces friction, but will actually increases wear, much like graphite does. He does point out things to consider like TBN, as it is fairly useful to avoid acid build-up if you go for long periods of time without changing your oil, so a high number helps you be a "winner". But in truth higher TBN's will, in long, term result in higher ash deposits in your engine, so a high number is not necessarily better or worse. If you change your oil frequently, high TBN's are probably detrimental compared to low TBN's. If you are lazy about changing oil, high TBN's are better.
I find it amusing and very telling when the narrator says toward the end he says he uses bargain basement Walmart's SuperTech in his personal vehicles.
