Have you searched this forum for the Mobil 1 "reformulation" history?

Porsche also said your IMSB wasn't an issue.

Oil formulations change to meet changing market requirements. Oils recommended by manufacturers are frequently dictated by CAFE standards. They don't care if your car wears out, they care that their fleet hits a target MPG. Oils too can change formulation over time to match newer car engineering demands. The "Mobil 1" you buy today may not be your fathers Mobil 1. ExxonMobil has no obligation whatsoever other than market pressure, to keep their formulation the same. Are you familiar with 2003 Mobil 1 formulation versus to 2014 formulation? Me either. The designer oils don't have these market constraints and can be tailored to do things like reduce wear at the expense of fuel mileage.

You guys are killing me with all this IMS and oil stuff.

My 1999 Boxster just went over 240,000 miles. It still has its original IMS and I use Mobil 1 (10W40 high mileage and 15W50).

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.

I am due to do my first oil change next week - 5000 on the new LN dble row IMS.
Ordered some Liqui Moly 2332 Leichtlauf High Tech 5W-40 from amazon. I have heard good things about this so decided to give it a try.

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.
