[DeTomaso] ZDDP zinc oil additive

[Ian H]

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.
