^^^^^Best statement in the thread---
Seriously, I think you'll see better overall results with wither the QS you are using or, the PPPU you plan on using
Why is that?
From all the UOA's on regular Mobile 1 on here, I am going to assume that some do not like it due to higher levels of iron in the UOA's versus other motor oils. Not sure I can argue with it and not sure it even matters that much, just stating what the trend has been with this oil with much user info on here. It has been enough to persuade me not to use it with all the other options we have for the same price or less.
