ZDDP Improver

[RUJA]

Im Looking for the best zddp improver that I can get to add to Delo 400 LE 15w40 and Delo Syn 5w-40. This is for a High Performance engine application. I know that there are many topics of these improvers on this forum but was hoping to start one to get some collective decisions. I know that many of these have been falling out of the marketplace. Is there a way to buy the raw ZDDP that anyone is aware of? Thanks in advance for the help.

Anything over 1200pm isn't probably doing much. Think the delo has aprox that, then might use moly for better protection (instead of just adding more zinc).

You can find the STP Oil Stabilizer (big white bottle) on clearance and its supposedly packed with ZDDP.

Since the new Delo LE meets SM I believe the ZDDP has been reduced to below 1200.

Don't know about Syn.
