I'm surprised that Jake has not had more to say about oil . . . I regard him to be the ultimate authority on this issue.
A useful correlation would be a comparison between change intervals and failures and a second would be a correlation between oils used (viscosity and brand) and failures. I think that Porsche has contributed heavily to the scope of this problem with both the specification of 0w oil and very long intervals. My 2000 S manual specifies 10w40 ----- before the 0w fad and I suspect that much of the preproduction experience with these engines used similar oil. I also think that high ZDDP content is wise if original bearings are still in use.
