Just research around, 0W40 is too thin and leaks much easier than 5W40, has very low zinc, and *some* 5W40s are recommended over 0W40, specially to prevent IMS leaks. As I said earlier in other threads, the head mechanic in our Porsche dealer told me to completely avoid using 0W40, and that's it's primarly used for gas saving, and is receipe for distaster for old IMS designs.

I can assure you that Porsche has done the actuarial work to assess the best technology to minimize warranty claims.

All the manufacturers are under pressure to increase fuel economy, hence the 0W-40.
I asked a mechanic at a Honda dealership about it when 0W-20 came out, his response was purely for fuel economy.

At colder temps the 0w-40 oil might actually offer less friction so there could be some fuel savings from using it, but probably just pennies per year...
0w-40 oil flows a bit better at colder temps but Porsche says unless temps are below -25C 5w-40 or 0w-40 are both good.
Even though there might be some truth to the Honda mechanic's statement I do not see a large number (make that any number) of Hondas on the side of the road suffering from inadequate oiling from running 0w-20 oil. And Hondas aren't the only cars being run on 0w-20 oil.
A thinner oil might actually run cooler due to less heat the oil generates because it is a thinner oil.
For your Porsche run an approved oil of the proper viscosity grade for your area and change the oil/filter at some reasonable interval. I like 5K miles.
Then enjoy the car.
Sincerely,
Macster.

Hi Guys,
I just bought my first Porsche—Grey 2005 911. The thing is it has 123k miles and no one would warranty it. Dealer has all the service records and IMS mail seal has been replaced recently, I’ve been told.
I’ve reading a lot on the forums and it looks like it’s possible that IMS may fail. That usually happens around 40k. I bought a higher mileage car because, it assume it’s been driven daily and well taken care of.
Did I make a mistake of buying a daily driver w/ a lot of highway miles ? Do I need to be prepared for any surprises?

Relax. Keep doing what the original owner was doing: drive the car and give it good servicing.
My 02 Boxster has 256K miles on its original IMS. What I haven't spent on IMS fixes and add-ons and the like I put in my Scotch fund.
Sincerely,
Macster.
