Another nice boring UOA where Mobil EP held up well and there seems to be plenty of TBN left. The previous run was Kendall GT-1 Max which also did well with plenty of TBN left. I put 0W-20 Castrol Edge EP 20K in the sump for this run and will be going to 10K mile oil and oil filter intervals and that will have me changing the oil/filter once per year.
