[DeTomaso] ZDDP zinc oil additive

[Asa Jay Laughton]

Chuck,

No, actually the point is, some of those oils -contain- high levels of 
ZDDP.  But be cautious, we aren't talking about the entire line of 
products, only certain grades of certain product families.  Not -all- 
Amsoil has ZDDP in it, some of it contains the same API ratings for new 
cars, SL and SM which no longer contain ZDDP.  You have to be careful 
and research carefully.  Sure, if you use one of the SL or SM lines of 
these products, you'll again need to add back the ZDDP.

Hope that clears it up.
