Too many older diesel's on the road for them to just remove ZDDP... Just look for API Service CJ-4 or/and CL-4 Plus... But, what ever floats your boat... or car... :glasses7:

Clif of Az. :coffee2:

So what's it got in it, PPM for each?

CJ-4 Rotella got reduced to about 1100 ppm of zinc, from about the 1400-1500 range of CI.
Ph went under 1K...

Apparently there aren't enough on the road to keep it from getting reduced. :) :glasses7:
