I guess my question is this; Is there any way for me to determine IF I have an acidity issue? Because if I don't have an acidity issue I don't think I would like to tinker with a combo that is otherwise working for us.


You can send an oil sample to the oil company for testing usually at no charge?



yes, take an oil sample and have an analysis run...the TBN will tell you if the oil is nearing acidity.

Unless you are running a lot of miles between changes, I would guess it is unlikely that you would have a problem if if the excess zddp clashes with the base additive package...
