Zinc additives

Nope. Where did you understand that from? Even the lastest CJ-4 rated stuff for the EGR/Particulate filterered diesels still has plenty of zddp/phos add.

The last spec I saw for the zinc content of the newer CJ-4 Rotella said it was 1210ppm and phosphorus was 998ppm. This is a little less than some others but definitely good enough. I also read that Rotella was losing it's ZDDP but that has aparently not happened yet.
