Damn, no more jumping the noob? I was just going to post a poll on how to start a 996. I favor a quick thrust to insert the key and a gentle twist to the right...starts her up every time.

I use Mobil 1 5W50 in the Boxster (used Red Line 5W40 very successfully for 3 years too).
I use Mobil 1 20W50 V-Twin in the 993 Turbo.
I do Blackstone Labs used oil analysis at every change (5,000 mile interval or yearly). This is the key to learning how your oil is performing.

Porsche approved Mobil 1 oils are 0w-40, 5w-40 (careful not all Mobil 1 5w-40 oils are approved) and 5w-50 (not 15w-50).
Look for the A40 on the bottle's label which is the Porsche oil certification stamp of approval.
Be sure you use a new drain plug washer and a new filter and and filter housing o-ring.
Be careful. The hot oil comes gushing out and you want have a proper catch pan that holds 10 or more quarts of oil, easy.
Have a torque wrench to ensure you properly tighten the oil drain plug and the oil filter housing.
Before you start get a oil change DIY document and read it front to back several times.
The job is not hard but you don't want to screw up, 'cause then it can get expensive.
Sincerely,
Macster.

Aspen,
To lube the Porsche I use a cocktail of Mobil 1 High Mileage Oil 10W-40 (6 quarts) and Mobil 1 Turbo Diesel Oil 5W-40 (4 quart jug)
Do not use astroglide......
Find attached a list of Porsche "approved oils", for your reference........
BTW.....Welcome

Ok guys, maybe I was a bit quick on the trigger. Sorry. I've just seen too many threads where new guys ask a question like that go bad and it's gotten old for me. Or maybe I've just gotten old.

Use a higher viscosity motor oil. There are several Porsche approved oils that are 5w40, rather than Mobil 1 0w40. Use of an oil that isn't API SM-rated with more Zn and P or an oil with moly extreme pressure anti-wear additives may improve engine life. Castrol Syntec 5w40 is an API SL rated oil that carries Porsche approval and is an excellent choice, and easy to get locally. Motul 8100 5w40 is another excellent Porsche approved lubricant.
By no means should you use any oil thinner than a 0w40 - do not use 0w30, 5w30, or 10w30 viscosities!

Some comments/opinions after reading this thread:
1. Ed, +1 on Shell Helix. An alternative brand with similar characteristics would be Q (Quaker State). PQS (Pennzoil Quaker State) is owned by Shell (since 2003 or 04 IIRC) and has been the more widely utilized US channel for such lubricants. Helix has historically been more of a European brand.
2. Mobil 1 synthetic isn't what it used to be - formulation-wise. Also, the definition of what can be called synthetic oil isn't what it used to be.
3. Zookie, being a factory-fill is not necessarily about a car manufacturer spending millions of $$ on research on the oil to use for their cars, it is mostly about marketing for the oil provider and supply-chain cost management for the car company. But, it's good to see that marketing works.
