I did this UOA for the heck of it after being in for 2 years. Wish I wouldn't have dumped it.
Blackstone Comments: Your F350 didn't see a ton of miles over the past couple of years, but that's okay. Oil doesn't generally go bad just from sitting and this oil could have stayed in use. As a reminder, universal averages show typical wear levels for this type of engine after about 5,600 miles on the oil. This oil run wasn't nearly that long, so it's right that wear metals are lower, especially iron as that should track with miles on the oil. The TBN read a strong 9.0 showing lots of active additive left. Go back to 5,000 or 6,000 miles on the oil, even if that takes a while.
