Thanks, Hib for "turning the page". The "m" in "mPAO" is a proprietary process developed by ExxonMobil, marketed under the "Driven" banner, ,if I'm not mistaken.
I think all would agree that testimonials are far from scientific evidence - mine included. And, too (oil) suppliers' marketing hype is also suspect - perhaps the worst, in some cases.

It would sure be refreshing to see independent test comparisons of leading brands (beit Amsoil or whatever) that are conducted in such a way as to be clearly understood by laymen. (I'd like to see how the mPAO compares to leading brands; tests done in a way the LT5 - in particular - could be demonstrated. (Considerations for timing chain lengths, cam sprocket loading, rpm, etc.)
And, too... There's "the BEST" and then there's "GOOD ENOUGH" to be considered. I haven't seen a test that is specific to the LT5's unique criteria to make a "good enough" determination. But, regardless of what I or any of us is aware of, is not exceeding the "good enough" product with one providing an extra margin for error a good thing - especially considering the cost to repair the LT5?
Looking forward to the next independent, comprehensive analysis including the "Driven" products alongside of other top brands.
