I don't know if the increase in Ca now offsets the benefits of the increase in ZDDP. The literature suggests that an increase in calcium detergent (as opposed to Ca/Mg or Ca/Mg/Na detergents) increases wear. Likewise, the literature also suggests that "too high a detergent level" is not good for your engine. I don't know why GM had to change it to begin with, but evidently they did.
