Not Ranked
Here's the levels for the old and new Rotella -
...........................CI-4..............CJ-4
Zinc.................. 1390 ppm.......1210 ppm
Phospherous.........1265 ppm.......1110 ppm
There's still more than enough to protect your motor. This Zinc thing is blown way out of proportion.
