I would tell Porsche to pound sand and use HPL 10W20.I have looked hi and low on your website for this info. Basically, does HPL have a 0W-20 oil that is Porsche C20 approved? I have a new Macan that will be under warranty for 4 years and cant take the chance of using a non approved oil.
Thank You
There ain't gonna be no warranty claim.
Of course it's not my Macan, but you do need to open 'er up now and then, friend.
