Head Tech at local Dealer finished testing 996's and 2 997's with his Porsche scanner, and found that the variocam engauges more quickly and positively in the cars that were using a 50W oil other than the OW40. Even moving up to a 5W-50 oil improved the varicam funtion on a hot engine. The only time there was any hestitation of the varicam was when the engine was cold, but this was with all weights of oils tested.
I had already proved this to myself by plotting timing changes with various oils. The 50W is much less abrupt and timing drop recovers 50% faster. It was nice the tech was able to confirm my findings. If you are driving like an old lady or in a climate where temperatures are less than 60F, it does not matter as much.

sand8, the opposite is true...a less viscous oil with a high viscosity index (M1 0w40) is what is required for the variovcam to perform at it's best.

here is the PCA tech discussing the TSB for Porsche approved oil weights.

Hi,
CDH911C2S - the M1 10W-? oil in that volume is insignificant and will not harm anything - rest assured
99Porscxhe911 - you said;
"It will only improve the oil protection of your engine. IMO, no one who cares about protecting their flat six should be using 0W40 in warmer climates."
Please provide the data to support this statement!
This is very important as your "viewpoint" is contrary to that of the Porsche Factory's Engineers (see all TSBs since 1999), the Oil Industry (API) and the collective of European Vehicle Manufacturers (ACEA)
Regards

All I can say is that Porsche of Manheim Germany put 5-50 in my car during the 30,000 mile service. Outside that 1/4 qt is not very much oil since your car holds 9 qts or 36/4 qts of which 35/36 is 0 weight and 1/36 is 10 weight. Oh never mind this makes my head hurt relax and drink a beer.

Unfortunately 5W50 isn't very common in the US. Mobil doesn't seem to think it'd sell well. I'd brought some back from Asia and Europe but it's friggin heavy and now considered dangerous cargo. I can't find it in the US easily without paying $12 a quart for it.
As for OEM recommendations, sure they also consider emissions, fuel economy and all factors in recommending 0W40. Plus 0W40 nowadays is different from 15 years ago. With new additives, the specs are very much closer to 5W50.

castrol syntec makes a 5w50 that is generally available in most stores.
does Porsche mandate Mobil 1 only?

Why is it that everyone think they are smarter than Porsche's engineers and claim 0-40 will do harm and does not provide enough protection in summer? I'm sure you are smarter than Porsche engineer OR Porsche wants engines to fail early to milk money from you.
0-40 makes very good performance on the dyno, 5+ hp higher than thicker oil such as 15-50. It also offers more efficiency.
If you are tracking in summer or sit in traffic like in LA or NYC, I doubt the extra thick oil is good / better.
