I have reviewed recent results from several Porsche Twin Turbos that have been run pretty brutally and the 0W-40 is right on vis and in 2 cases a significant decrease in wear metals occured after they switched from Mobil 1 15W-50..
Yes, Mobil 1 0W-40 can be a challenge to find. If you cannot find it locally, it is available at AVlube.com which you can get to via Bob's Order Page.
