If you were to graph a variety of variables related to engine longevity, and you used a proper weight oil (syn or dino), an oil with high ZDDP, and did average change intervals - I'm almost positive that oil in that signal graph would be well with the confines of the other variables. I've driven just about every car I've owned from Honda Civics to high horse power twin turbo audis to well over 200K miles, and not a single one was even close to needing a rebuild.

Unless you track your car a ton, or live in some extreme environment, just about all the oils recommended here are completely fine, and the difference they have on your motor is going to be negligible compared to how you operate it, maintenance, etc.

Buy a good oil (syn or dino) in the proper weight with a good amount of ZDDP - and stop worrying about it.

There is nothing worse than someone saying "I use XX oil and really like it because it of things that have no correlation or causation to other things, and because a friend said something about YY oil."

I use BP 20W-50 in the summer, and will switch to 10W40 in the winter. Previous owner used Valvoline VR, and he owned the car from 50K miles until 194K miles with track time. BP is easy for me to get, I know it's good oil, and I never loose a wink of sleep wondering about this stuff.
