This weekend I will change the oil & filter as I always do every 10,000 miles.
If Mobil 1 is good enough for Porsche, then it is good enough for me. If I can find royal purple in 5 quart jugs like Mobil 1, I will start using it.
Just my two cents.

But you've got a 2.5
Dual row bearing has better longevity.
You also have more chains.
And you've logged (presumably) ~16k miles avg per year.
more miles, more time for the engine to burn off build up.
Most IMSB's that fail don't really many of the above.
Thus they need a better oil than the one Porsche gets paid to use as factory fill, assuming that's how the arrangement works.
Different levels of protection for different styles of driving and maintenance habits.
