[DeTomaso] ZDDP?

[JDeRyke at aol.com]

Don't believe any published lists of ZDDP content. Under Federal pressure, 
manufacturers were pulling as much additive out as they could while selling 
the lube as the same product. So the ZDDP level changed with every batch. 
Analyzing the stock you have is the ONLY way to know how much is in there, and 
as I said, Comp Cams seems to think that too much additive causes trouble, 
too. Good luck- J Deryke
