After the first (very happy) 10.000km, and about 4 trackdays, i have to change my engine oil.
I have bought the original oil filter, but the question is, what oil can i use?
I want to change it about 1 time at year, maybe around after 15.000 km, and i do about 10 trackdays for years.
Can you tip me some type of oil correct for my use?
Remeber even (if can be usefull) that in my country the maximum temperature can be by -10° (celsius) in winter, to +30° in summer!

Engine oil opinions are like noses, everyone has one.
Get the list of Porsche approved oils (published by the Porsche factory) and pick one that's readily available in your area. All of them are multi viscosity and will be fine for whatever temperature you will encounter.
Other than that, here's my opinion on your strategy: Change it more often than 15K if you do track days-especially if you use something like 0W-40.
Ciao!

Teclis - a couple of excelent threads on oil changes and oil change alternatives can be found on the Cayman Registry site at:
Cayman Register
and on alternate oil choice(s) i.e. Mobile 1 5W-40 diesel:
Cayman Register
Personally I'm leaning towards the added protection (addatives) that are in US truck oils, but have been gradually removed for EPA reasons from our USA automotive engine oils.

Attached below are the Porsche Approved Oil TSB recommendations. I think any brand name synthetic oil meeting those specs would be satisfactory.
You are right, access may be limited to registered parties - Well the rest of the gist of the arguement in favor of the "diesel" 5W-40 blend can be summed up in "RoadMaster"'s point
" . . . I've used the Mobil 1 Turbo Diesel Truck 5W-40 blend for more than 5 years in my various Audi's, my Volvo XC70, my garden tractor and my snow blower. I continue to use the M 1 0-40 in my Cayman S and Carrera S because of the range of temperatures here in the Northeast. The 5-40 blend also has higher levels of anti wear Phosphorous and Zinc, which isn't so good for the cats., but better for cams and lifters, than does the 0-40. I still get it at Wally's Mart, but the 0-40 is getting harder to find there at my store, also.
You can look at a good comparison of the various M 1 oil blends at Mobil's site here:
http://www.mobil.com/USA-English/Mot...duct_Guide.pdf
.... and The use of Diesel and "Turbo" formulated oil goes back to air-cooled engine days when the conventional dino oils were questionable for holding up to the high heat the oils were subjected to in the air cooled 356's, 911's, and pre '99 964's, and 993's. Since the oil doubled as both the lubrication and cooling medium early oil break-down was a common concern. The then diesel and later "turbo" oils (I think Valvoline was the first with Turbo Oil marketing) became common usage among those of us with air-cooled Porsche's as these oil's were formulated to stand up to higher internal temperatures. In fact, if you go way, way back into early 356 literature you will find that the factory did a lot of oil testing then, and after exhaustive testing found that only the then classified "Diesel" oils held up to the high temperatures. Oil's are obviously far superior today, and we have the benefit of synthetics as well, but some of us have long memories and continue to use what worked well for us then. _____ "
taken from that thread. As supplemented by "Bill-Banger" 's " . . . I've used the diesel 5W-40 oil in my '06 CS and here's my take on it: I used to sell Exxon oils, later Mobil as well when the companies merged, as an Exxon-branded oil distributor, and was privy to much of Exxon's technology. Many times an oil will not meet certain specs (like certain ACEA specs) simply because the oil company did not submit them for testing under that particular discipline. It costs money to have an oil tested, and if an oil isn't targeted for some markets, then it isn't tested for those specs, but quite often will actually meet them.
Case in point, Unocal (I was also a Unocal distributor) sold a racing oil in SAE 40 viscosity that was rated SB, a very old spec that basically meant it was oil, not much else. I called the Unocal oil engineers to ask about it, and was told this oil was sold mainly to racers, NASCAR teams among others, and was not intended for the general public, but that it was a very modern oil for its time and met all the passenger car specs, which I think back then was SF or SG. I sold it mostly to drag racers but it was perfectly good for street cars, although it was a single vis oil and wouldn't be good in colder climes.
I believe the Mobil 1 diesel 5W-40 oil will probably meet the required specs for Porsche, can't prove it, but the Phosphorus and Zinc content are a little higher than the 0W-40 I admit. Here in usually hot Alabama I like the idea of running 5-40 instead of 0W-40 and might even run 5W-50 if I could find it.
BTW, the 5W-40 is available here locally at O'Reillys and Advance Auto Parts stores. " and ".... I just pulled up the tables for Mobil 1 oils, the 0W-40 has 1000 ppm phosphorus compared to 1100 for the Diesel 5W-40. Zinc is 1100 for the 0W-40 and 1200 for the 5W-40. In Mobil 1's answer page they say it is phosphorus and not zinc that is called ZDDP, and is more critical for bearing life.

and clicking the underline 'table' at the end of the answer will take you to the tables. I think they have been linked here on an oil question before.
I'd buy the ESP Formula M 5W-40 but it just isn't available anywhere I can find. " end Bill Banger quotes.
Hope this helps, Now back to your regular religious programing of choice
(I've found arguing about oil choices frequently approaches and sometimes exceeds thread on religion and politics)
