I should have said "shouldn't".How you or I treat the environment is our 
own business,right-wink,wink? I run leaded race gas on the street,and an 
Edge EZ on my truck.Let the glacier's melt...I live in Denver.

I read somewhere that the diesel add packs,specifically the higher 
amount of zinc degrades the catalytic converters quicker than an auto 
only formulation.To what degree,and how fast I don't remember.

With the diesel trucks now going with ULS fuel and particulate 
filters,zinc is now being phased out of those oils as well.
