FYI. Porsche NEVER recommends the use of any oil additive. Not that I do everything Porsche recommends (but most).
I'm not a believer in oil additives. I'm a believer in using a better oil (from data I see in my Used Oil Analysis- Blackstone Labs) and just changing the oil a little early. I do 5,000 mile intervals now. That's about 2 oil changes from April till October. The other months the car sits in my heated garage for winter storage. Not a daily driver. It's a sunny day toy.
This is really not rocket science. Pick a high quality full synthetic oil (Motul, DT40, M1 5W50....just to name a few) and change it at least every year and every 5,000 miles. It's pretty simple. Don't over think it.
