Stay with the 5K-mile oil changes and check back to establish engine wear trends. Nice Porsche!”
THAT is a very interesting recommendation. There have been many debates on this forum about whether the M1 will go to 15K or 20K miles. Personally, I used the 7500 interval myself.
I do respect the Blackstone guys so please report back when you do your next analysis.
Thanks!
