FYI-I had my oil changed in my 2019 911 GTS at a local dealership for the free 10,000 mile checkup and they used 0W40 Mobil-1 A40. Also the change was done by a Gold Certified Mechanic so I assume that he knows it was ok to use.

Also I’m in the USA.

If you read between the lines of the what the Motul rep posted in RL, the C40 protects the engine less.
