Not very many people would have much to say if the criteria for being able to talk about something was that they had actually done the thing they were talking about. There aren't too many people that have actually beat the tar out of several engines using the different oils in question and then tearing them apart to mic the moving parts and report the findings. All the rest of us just talk about what those people do. Our biggest problem is that it can be hard to acquire the findings of those people that do that with the oils we want to know about. Again, we do what we can.
To make you more than an armchair quarterback you would have to have done more than watch two engines expire while finding no heads-up w/UOAs. Please explain in excruciating detail how watching two engines die makes you an expert on the differing wear in passenger car engines using 20w vs 30w. What oils and what form of death? Was it relevant to the point at hand? How did each die so that the UOA became pointless? Perhaps all of our UOAs are pointless and we're all wasting our money. Perhaps not.
I am not negating the tests the guy was a part of, but "it's a secret and I can't tell you the details" is hardly an unreproachable recommendation of his opinion. The degree to which his opinion is relevant to our type of use, then, is also a secret. How much difference was he alluding to? Was it statistically significant? Statistically significant to automotive companies spending millions on research or to guys that argue over M1 iron being 10-20ppm higher than PP?
