Oil is 12 months old with 7,250 miles on it. Super majority of these miles accumulated over spring and summer of 2019. Not very many short trips. 99%+ of trips oil reaches operating tempMostly suburban traffic at 45-55 mph. About 1,500 mi of road trips. Brutal high humidity 90F northern Virginia climate.
I did use about 7-8 bottles of various fuel system cleaners over the course (techron, gumout, bg44, etc)
Zero oil added, oil level stayed the same. Lots of daily WOT
