E.J.,
You've got it all wrong... I don't care about extending the life of my motor by switching to 0w40, I'm just looking for the extra 1 or 2 hp.

C'mon, EJ, you know the schoolbus is sick of that thick-like-molasses Guiness nonsense. What it's really looking for is some thin, Fishman-style Miller Lite to let the "components" slosh around a bit easier when you're just getting started!
Numerous scientific studies prove that Greg's insides show less "wear and tear" and smoother lifter operation than mine, especially in the fast corners.

From a Mobil website:
"Q If I want to start using Mobil 1 now, will it mix with my old engine oil?
A Mobil 1 mixes with any engine oil - even non-synthetic mineral oils. However, to get the maximum benefits from Mobil 1 you should completely drain your engine and replace with Mobil 1."
I hope that puts peoples' minds at ease

The cars came from the factory with Mobil One 5w40.
Up until a few months ago, you couldn't buy any Mobil One in the US that was a 40 weight, so many started using 50 weight. Now that 0w40 is available here, I think its a "no brainer" that the 40 weight is the one to use no matter where you live.

Here is a relatively low hassle compromise to the 0W-40 vs. 15W-50 debate: Make your own 7.5W-40 by mixing equal parts of easily obtainable Mobil 1 0W-30 and 15W-50. Simple to do at oil change time.

My mechanic flat out refuses to put 0-40 in the 911 engines! He is a race engineer running 911's for the last 3 decades so he knows a few things...
After I saw the condition my 0-40 oil was coming out of the car with just 1500 miles on it ( 2 DE's and street) I was too convinced of the value of 15-50 especially in areas as hot as Houston.
Porsche used to recommend 15-50 oil. Now they changed their tune...I wonder why! I'll stick to 15-50 thank you!

Why not use Castrol Syntec 5W-50? It is on Porsche's latest "approved oils" list IIRC.
On the Mobil1 website, Mobil has the following ambiguous comment on the question "Why do Castrol and others market SAE 5W-50 grade synthetic motor oil while ExxonMobil in North America does not? Does SAE 5W-50 offer advantages?"
-> "SAE 5W-50 is not recommended for the vast majority of newer cars sold in North America. They are designed for SAE 0W-30, 0W-40, 5W-30 and 10W-30 grades...and this is what car manufacturers recommend."
