As a new Cayman owner living in the Northeast (Pennsylvania) I would appreciate recommendations on replacement oil. Is Mobil 1 @ 10W-40 most recommended or is 10W-30 preferred?
Mobil 1 0W-40 Fully Synthetic as per the user manual.
Nick is correctomundo - you should be using Mobil 1 0w-40w. The 0w-40w is important because the oil "inflates" the lifters, and the passageways to the lifters are tiny, so you need the 0w to makes sure the oil gets in there when it's cold.

Follow the owners manual? Ok, who thought that up?
Thanks Nick. The only reason I asked this question is because for other vehicles I have owned, there were often recommendations other than those found in the manual. Such as oil change frequency as has been discussed many times on this site.
TuffOil
:beer:
I had no idea that it was 0W~! I guess I never looked closely and assumed it was 10W~. I've never heard of "no weight" oil and up North were we need more protection from cold starts, I use a combination of Marvel Mystery Oil and Fluoramic's TuffOil and 5-30W Casteroil.
However, no need to worry--I've no C/CS to screw up.
What would you think of adding TuffOil to that, though?
TUFOIL PTFE Engine Treatment Buy Tufoil for engines
I have used TuffOil as I have been able to afford in my last three cars and AFTER breakin [Gotto let those rings seat!] this stuff makes everything smoother, quieter, REV FREER, takes out all and any harsh vibration.
First treatment is 16 oz added [or, rather substituted] to an oil change and thereafter use between 1-4 oz with, of course, 4 oz. being ideal.
I'd love to hear what others here might think and especially might experience after using this stuff.
My prediction is that there'll be raves and some will even think it should be Dynoed!
Maybe Fluoramics could become a sponsor?
How about Marvel Mystery Oil becoming a sponsor?
:banana:
I am amazed that I don't hear more about gas tank and crank case additives on this forum.
Cheaper TuffOil
Tufoil is in the Guinness Book of World Records as "The World's Most Efficient Lubricant." The Canadian Government's Kapuskasing lab reports significant fuel savings and easier cold starts for gas and diesel engines. With fuel prices rocketing, better mileage is important. One car manufacturer (OEM) is using Tufoil in their factory on machines.
Welcome to Fluoramics Inc.
It's cheaper to buy directly from the manufacturer rather than the link I previously posted.
Well, y'all are welcome to use whatever oil you want to in your Cayman or Cayman S, but the oiling system in these cars is different from most anything else you have probably owned in the past (please see my post above), and that's why the nice folks at PAG recommend 0w-40w, and not mixed with Tuffoil or Marvel Mystery Oil, or snake oil, or anything else.

I'll be adding TuffOil to that recommended by Porsche and I'll bet my engine lasts longer and performs better for it.
Go! You're on. Do a complete tear down for base measurements and then diligently record every maintenance and operating parameter for the next 300K miles - then tear it down again and post the results. Of course you'll have to do this with maybe 50 Caymans on each test sample to make this valid but that shouldn't be an issue!
Really, if I do even the slightest 'devil's advocate' test on any of these super additives, I can poke holes in all their claims.
Kapuskasing showed higher cranking speeds? I can claim the same when I shift from 5W-30 to 0W-30 in the winter. Reduced wear? Easy, make the base comparison oil some straight 30 weight with minimal friction reducers. Four ball test? Put some PTFE or zinc compounds in with the miracle sludge and you can ace that test. Make my engine last 300k miles? Make sure that you use fringe mileage claims from guys who change their oil every 2000 miles. And the list goes on........
I believe even DuPont says PTFE added to oil is useless.
