Will do.

Maybe that's why they say it's been discussed "to death" over there.

Regarding ZDDP, since that's a major point of contention with TWS, they say it can harm the catalyst, but that there are other additives (titanium based) that can reduce harm to the catalyst. For our latest V8 build, we broke the engine in with diesel oil since it contains lots of ZDDP, maybe try to find some with the right viscosity and do a UOA on that as well?

I know motul makes 10w60 diesel oil.

Here's a thread comparing levels of P and Zn in a bunch of oils:

And there's also this if you don't want to go with another oil: http://www.zddplus.com/
