I think Pablo and Frank are talking in regards to same action and putting their own 'plausible' spin on it. Of course as a guy that is pro Amsoil, Pablo is coming from one angle and Frank stating something that perhaps factored into things.
For me, it's the whole 'doesnt have API certs' vs 'prove it caused the issue(failure etc)' argument.
Amsoil is avoiding issue here, that is clear, by moving to be even more consistent with OE spec'd fluids than before. They were pretty solid already, AFAIK, when I came onboard.
For instance, their MTF Synchromesh works great in the Civic I drive, but they don't spec it because at the time the book for my car was pre-Honda Genuine MTF. The later aftermarket manuals/Honda have since back spec'd for the HG MTF, but Amsoil is going on factory released time of build from what I gather.
Like their info on cars with known issues and recommending not extending intervals in apps with known issues. They have looked out for the customer more and more, IMO.
It's more like avoid confusion and potential 'issues' with people more so than with performance in an app, IMO anyway.
For instance, use their MTF in place of Honda Genuine is a win for me, while they only recommend either a 10w-30 or 10w-40 like the manual initially called for.
No problems with Frank or Pablo, I like 'em both. Oil guys with passion that don't always approach things the same way.
Both assets to this site. Enjoyed the back and forth myself!
