The  data sheets specify the amount of zinc, both 
concentrated and compounded,  in their oils.



Hi tony,
Well, I checked both the product bulletin and MSDS for several of their  oils 
and nowhere did they specify the amount of either Zinc or Phosphorous. 
 
But even if they did specify the amount of zinc, what would that mean since  
there is no API requirement for the oil to contain zinc, only phosphorous?
