Some of you might remember this thread about the ticking/sticking/clanging noise I was getting with my low-mile 2006 Porsche Cayman S. Per the recommendation of a reputable shop in my area, I'm running 0W-30 for the next thousand miles or so. For whatever reason, the 30 weight worked to drastically quiet the noise and I think it continues to improve with use (at this point I can only hear it when I remove the sound deadening material above the engine and I really have to listen hard. It has a similar intermittent cadence as before but much less often and much less severe).
Alas, these engines are "supposed" to used 0W-40 or 5W-40 so I'll eventually be going back to a heavier grade. I had used Pennzoil Ultra Euro 5W-40 for 2500 miles with no issue. I had just put in new PU Euro 5W-40 when the problem occurred. As the problem has subsided now that the the PU is out, I'm somewhat hesitant to use it again. I realize that that might be kinda crazy, and doubt that the PU was the problem, but with so many quality oils on the market I'd rather just switch to something else and cross that off the list of potential root causes.
I'd love your direction for a car that 1) has had the above issue 2) will never see freezing temperatures 3) will regularly see 90F-100F temperatures 4) is driven hard but not tracked 4) will be driven about 2500 miles a year. In the running for my next fill:
As always, you guys rock. Your insight is much appreciated!

- Liqui Moly Synthoil Premium 5w40 ($7.50 a liter) - Lubro Moly says this is a synthetic. This is what my independent Porsche shop recommends. It is NOT on Porsche's A40 approved oil list, but as I'm far past warranty I'd rather have something that protects as well as possible. It's relatively inexpensive which is a nice plus.
- Liqui Moly Top Tec 4100 5w40 ($8.50 a liter) - This uses "Synthetic Technology" according to Lubro Moly. It is on the Porsche A40 list.
- Amsoil European Car Formula 5W-40 ($10.15 a quart) - Pricey, but everybody says that Amsoil is great.
- Red Line 5W40 Motor Oil ($11.49 a quart) - Really pricey! TPC, a Porsche tuner that does lots of work with aftermarket turbos recommends this in all their cars.
- Joe Gibbs Flat6 DT 40 ($129.99 for 12 quarts) - Flat 6 Innovations is well known in the Porsche community, particularly amongst 986 and 987 enthusiasts. Flat 6 had Joe Gibbs custom blend this oil. I've heard little else about it.
