I don't know how mnay of you read (or will give credit to) Blackstone's newsletters..but November's discusses a topic we see here on BITOG in increasing numbers. Good ol' ZDDP levels in the SM/SN-spec'd oils, and the effects on flat-tappet equipped engines.

Give it a read, even if for [censored]-and-giggles.

Ahhh..that's what I get for not checking all the forums. D'oh
It's OK. Interesting read, regardless.
After looking at the UOAs, would you say that wear did increase in your engine with low amounts of ZDDP?
Will you be testing oils with high levels of ZDDP to see if the Iron/Lead levels decrease?
