JD,
The Porsche approved oil list doesn't have any 30 grade oils listed on it -- pretty much 0W-40 and 5W-40 (couple of 50 grades) and all are synthetics.
After my factory fill, I used Motul 8100 5W-40 for 3 oil changes and Mobil 1 5W-40 (TDT) for 2 changes. I just recently changed the oil and have started using Redline 5W-40. Although the previous oils gave me good UOA reports, the car always would have valve train startup noise. With Redline, that noise is now gone.
I change my oil at approx 7500 mile intervals, mainly because the Porsche oil tests are run for approx 200 hrs which roughly equates to 6000 miles driven.
BTW, as we've both seen, summer is fading fast in our area so don't worry about the coco butter
Regards,

PS: Tried to upload my UOA history (pdf) but it didn't work (IE or Mozilla).
