Again, I agree and change my stance as from prior, since I didn't see the top-up of oil before.
The addition of 2 quarts between changes definitely helps make the TBN 'appear' better off. Keep it at 15,000 max on PP in this app, current driving habits, etc.
If no top up was possible during this interval, I wonder if TBN would have still been above 1.0?
PS: 72,000 miles in 2 full years?!

Thanks for the replies.
BTW... I use Wix air and oil filters. They are inexpensive, work well, and are made in the good ol' USA.
Was the whole run on one filter?
Yes, a Wix oil filter for 1 interval or was the oil filter changed mid-way?
