All synthetic flows at super cold temperature even straight 50.
Most important to let the car idles for a few minutes before pulling away and then warm up the rest of the car slowly.remember that water temp comes up a lot faster than oil temp
Just buy good stuff
Please do not use 0W30 in your 911, that viscosity was never designed to be used in that engine and no one makes a 0W30 A40 Porsche spec approved oil.
As you know the 2 approved grades are 0W40 and 5W40 for water cooled 996, 997 generarions etc. 5W40 is a better all round grade for your engine as the lesser grade spread benefits you in the upper ranges. If you live in an area that consistently sees -25 deg c in winter on a regular basis then 0W40 is preferred.
I plan to change to Castrol soon. It is readily available, priced well, rated very good and a good range of products. Most of the 996 turbo guys say it removes a chatter in the engine.

Don't forget Porsche A40 approved Mobil 5W50. So there are 3 actually.
Just to add some colour to the discussion .. all these approved oils are being used yet we still have " Porsche approved" cylinder scoring ..
if someone doesn't do something different there is no reason to believe it will magically stop happening. I applaud the guy who steps out of the conventional norm to resolve an issue the manufacturer wont look at .
I am sure lots of guys said : "don't dare do the LN engineering IMS fix, its not Porsche approved".
Has to be based on sound science of course and I am not saying changing oils will prevent scored cylinders. But discover does come from the adventurous few ..
I will add colour as well... Just for fun... After using Mobil 1 for years, I switched to Castrol and noticed a drop in consumption and better all around pressure with similar weight oils. Castrol was cheaper at the time and it made me a convert. This was in a heavily modified track 944 Turbo. I have used Castrol in everything since that experience. I tried the more expensive exotic oils also (Agip, Motul, Lucas...) but the additional cost and difficulty in obtaining them never turned out to be worth it over the availability and price of Castrol. Just my experience...
Cylinder wall scoring has nothing to do with the oil. It's primarily due to incorrectly toleranced piston-cylinder clearances and poor coatings from the factory. It is amplified by cold weather.

Same here, also have a buddy that tests all his oil during oil changes. Castrol had great results vs much more expensive oils and mobil 1 was one of the worst. I use Castrol 5w40 in all my 3 Porches and mix 5w40 in with 5w50 with the car I track with
We were just having an "informal" conversation and I asked him what could prevent scored cylinders.
He uses Titan Oil pics attached...
Then he mentioned why not use 0w-30 - He didnt have it in stock he only had 5w-30
His words "... "0w" would be better for winter because it has more viscosity and would stay longer, "30" would not be a problem due to the "summer" we had.. very mild..."
This oil would only stay in for winter... Not saying I will do it... Just trying to stir the pot, like iceman said...
I purchased the 996 as a beater, maybe not the appropriate car for the winter, but is MY appropriate car to drive... Not planning "not" to use it, thats why its a C4S.
Of course Im trying to prevent any "possible" damage.

...and get a new mechanic.
