could not agree more ....
the recommended oil is obviously the factory fill ... shell .... oh no wait hang on ... its Castrol .... oh no wait hang on its Mobil One .... damn , I keep forgetting .. who got the latest contract and wrote them a cheque ?
but speaking of such things I'm pretty Sure Porsche doesn't own a refinery , so who is putting the stuff in the can they are putting their name on ?

Apply the above along with time-tested data, both real and anecdotal from experts such as Steve W., et.al., and one may make one's own informed decision. To simply --blindly-- trust a manufacturer's recommendation in today's age of hyper litigation and CYA policy is the antithesis of informed decision making, IMO.

The 540rat blog is also quite informative. Take the rankings for what it is ... one guy's independent but consistent oil testing results and draw your own conclusions.

Hey, a question about Motul 300V 15w50: This is a product that Steve W. has recommended and I am considering it. However, it is a ester synthetic (apparently). If I wanted to change to this in a 3.2 Carrera, would there be any mixing issues between the new 300V I fill into the tank and the two or three liters of old oil (Porsche Classic 10W-60 in my case), that will remain in the oil cooler and lines (forward of the thermostat)? If they mix without issue, that is great...

JMHO,.......
Leave the 0w-40, 5w-40, and 5w-30 oils to the water-cooled cars. I've seen too many (expensive) issues to ever use those in air-cooled cars.
Stick to the 15w-40, 15w-50, & 20w-50 products unless you must drive in near arctic conditions.

Thank You Steve, my last quick question is Mobile 1 makes a great 15w-50 with a little higher zinc levels, i think 1300 ppm......Can higher zinc levels hurt catalitic converters ?..........also porsche has an updated list every so often, as to what oils " MADE " the approved list.....do you think its absolutly imperitive to pick from their " LIST " ?
my air-cooled '87 Coupe now For Sale, under my watch received Brad Penn, I've read up on it and believe in the Zinc, agree with above ZDDP comments and was let down when Porsche came out with their Classic Oil but initially didn't publish their Zinc, Phosphorus levels... I also pulled a bit of a "cop out" on the Cat issues, I deleted mine...
