So let's agree on one thing - the oil discussion is like discussing religion, everyone has a different opinion...

I got what I needed out of this thread - go to Walmart for Castrol, which is my choice. But still not sure if anyone answered the size of the crush ring, i.e., is it 17MM, 20MM, etc.

IMO, I agree with the previous point that the Porsche engineers are told what to work with (M1) and in my occupation, upper Mgt. gives us the project end dates from hell and tells us to get it done knowing it's unrealistic! LOL, all the same crap...

Thanks a ton,
