Funny, I'm sure I still have some brad penn hiding somewhere. First time I saw that it was pretty cool, for motor oil.

Similar comparison, I'm sure you can find others with different results.

So pretty much both good oils and no real big advantage the Cayenne boards are extolling Molly! I'll cary on with Mobil 1

I didnt even sleep at a Holiday Inn last night, I'm not the expert! But, I agree with your assessment, pick your favorite brand and change it often.

Surprised it hasn't been mentioned yet, but Porsche has a spec for oil - A40.

You can find various lists online (from different dates.)

Took a long time Brad Penn oil only motor apart and it had the most carbon of any good compression motor I have seen the insides off. It had gotten so thick as to flake off. This was fouling the plugs. YMMV.

There is no substitute for using German oil technology in our German sports cars... and compatibility will be maximized if that car has Fuchs wheels.

FWIW, I found a 2019 version of the A40 list:

But the cam lobes and rockers were pristine though, right?
