I've been using Shell Rotella T6 for the last year. The engine used to have a quiet tick, but that went away with this oil and the engine just feels happier.

Wow......all these replies and I dont think even two people are using the same product. The options are all over the map. Good knowledge gain here.....glad I went for the quickie post.....
Anyone else have over 150k on your 986?
The reason that I purchased such a high mileage 986 was the previous owner was a Porsche mechanic. Many of the common issues have already been repaired.....and fingers crossed I can keep up with future maintenance...

It’s really very simple.....
.....Don’t suffer analysis paralysis.
Just pick any good oil in 10-40 or 5-50 that you can easily source and fits your budget and CHANGE that oil every 3,000 miles.
Replace the water pump and Air/Oil Separator every four years.
Replace the brake fluid every two years.
Be prepared for ignition coil and cam chain tensioner replacement at some point down the road.
That’s it.
Use Shell gasoline and let her warm up properly before driving the snort outta her.
Don’t worry. Just enjoy the machine.
Welcome to the party, Pal!

It is very easy to over analyze anything but unfortunately " what is the right oil " is not a simple one part answer . Let's face it ANY oil will work and if you change it often enough you will probably get by . However to REALLY know what's going on with any oil is to have it lab analyzed . And you have to do multiple samples . Here is an example: after Jake built my engine and it was broken in he suggested I use Driven DT40 synthetic . I did and we started doing oil analysis . My seat of the pants reaction was hey this oil works great because I wasn't burning much and the motor sounded good . But after a few samples Jake didn't like certain properties he was seeing in the oil reports .
So he had me switch to Brad Penn 10w40 semi-synthetic and we have done a few more samples , he stated my oil analysis is perfect and has been over several samples . I believe in my case the DT40 was having some separation issues , certain properties of the oil were being affected by the fuel . It's all way over my head but Jake has done probably 10,000 oil samples on every oil out there so if he recommends BP for my engine that's what I'll use .
Keep in mind this is about MY engine in MY car after multiple oil samples . Your results may be totally different . If you like making decisions based on real evidence then do some oil sampling . If your not interested then go with what you like and drive it like you stole it . I see Particlewave is using Rotella , an excellent oil with high zinc/phosperous content due to it being a diesel oil . Nothing wrong with running it in gas engines . End of my story , sorry for the long reply .

I will be honest with you guys......I have learned more about my new used car on this oil thread then I possibly imagined. I really appreciate the replies and added knowledge. Originally I was thinking that due to the high mileage that my car might benefit from a high mileage oil or viscosity.......u guys have given me plenty of options to chose from. This car is only driven for fun so not many miles per year.
Many thanks!!!!
Now where is that beer thing...........ahhhhh

What did you end up going with?
I have 128K miles on my car, always used M1 0W-40, except one time I used either M1 5W-30 or 10W-30 and got horrible engine clatter at start up. By the end of the week I had drained the oil and put 0W-40 back in it. I'll not play with the oil viscosity again since the engine has done fine with M1 0W-40, so why mess with good results.
As for the oil filter, I use the K&N PS-7011 Pro-Series Oil Filter, usually off eBay or Amazon and bought a bunch of crush rings, I think it was 20 from Pelican when I was ordering some other stuff that got me free shipping.

I bought my car very recently and it came with some old paperwork. I know in the past it has been on Mobile One so for that reason I am just going to stick with Mobile One. Some of the replies mention Porsche now recommends a diff viscosity.....so thats my last desision....0W 40.....or 5W 50 ....not sure if M1 makes 5/50 or not. So ya...I havent got around to changing the oil yet. Just did the cigarette lighter conversion today. Have to replace the starter next I believe.

Using Rotella T6 5w40 for at least 10 years on all cars with my family; SAAB turbo with 170K miles, BMW X5D35, VW Jetta EA211 and 97 Boxster. Just love this oil! It contains higher ZDDP than Mobil 1, got to be good for IMS bearing! Works great, reasonably priced, readily available, no complaints.

Piper I can’t believe you actually started/extended an oil thread! Wait, I think I just did the same thing as did TeamOxford. Yawn is right.

HAHA! Well, I did apologize in advance! 
I still don't understand why so many people use so many different grades, when the manual seems pretty specific.
OOPS! I just kept it going!

What year was your manual written? Think back to that year. How many M96s had failed? How many in the years since then? Go back and read the first page of this thread for a recent list of Porsche approved oils. Maybe Porsche changed the list as they learned more and oils improved. ...or maybe they benefit from promoting certain products.
disclaimer: I used Rotella T6 on my waffles this morning. It is not approved.
(OOPS! I just kept it going)
