Nothing exciting. Bought another 7 quarts of Valvoline Restore and Protect. Did a drain and fill prematurely about 1,300 miles ago. Kept my old filter on. Fella online removed his oil filter after having ran R&P for the first time and found quite a bit of gunk built up in the filter. So I decided I'd run it through about 1,500 miles and change the oil and filter out to start "fresh". I was only about 5,000 miles into that oil and filter before I decided to move to R&P. So far my truck seems to like it better than Mobil 1. Truck is at 78,xxx miles now and knock on wood - there's been zero powertrain issues so far.
