[DeTomaso] ZDDP zinc oil additive

Thu Mar 12 11:50:52 EDT 2009

Yes, 1200 is enough.

"synthetic" means the actual oil component is partially synthesized.? ZDDP is an additive which must be added no matter what kind of actual oil component is present

On the bobistheoilguy.com site the experts say that other components (I believe moly and calcium) can also work in a manner similar to zinc, but they must not be as good or as cheap or we wouldn't still be seeing ZDDP in oils.

the only indisputable advantage of synthetic oils is that they flow better when cold.? Most oil has to be changed because it gets dirty, and synthetics will get just as dirty as dinos.

I  just checked the Mobil 1 web site an they say that their 15W50 (which is 
what I use) has 1200 ppm of ZDDP.   Most others in their line have 800ppm, a 
couple have 1000ppm.  Is 1200 enough?  I don't know  but it's better than 
nothing, I guess.

Heres a chart of their product line The last line labled Phosphous content 
is the ZDDP level.
