Bottom line is that synthetic oil is not going to hurt an engine, but a dino oil may give plenty of protection for that same engine at a substantially lower cost. UOAs will tell the tale.

I agree with some of your post but, I believe having the most information possible helps to make a better decision. If the general information were not available, no one would think to try anything outside of Motorcraft. This information is strictly that. It's not to say brand X is going to save your engine but rather, brand X is a true POA4 and has more zinc content etc. Those bits of information are valuable to racers.
