According to the report it's up. I'm sorry I can't get to my 17 3.6 Outback report right now. Look up my posts for it. I slowly moved to 10k OCI on mine using M1 EP and a Fram Ultra. Maybe looking at mind will help shed some light on the copper trending.
Did you have any work done? I'm at 75k now and will not do another UOA til arond the 100k mark.
Side note, I assume your 19 has CVT? I plan on a CVT fluid exchange within the month. What do you plan on for CVT maintenance?
