seems a little long. 5.9 cummins guys say it took about 60000 miles for that engine. maybe this caused some confusion?
Blackstone Oil Report For 6.4 ~7100mi on Castrol
Just like it says, I changed oil about 10 days ago and got my report from Blackstone Labs Thursday. It appears that my motor still isn't broken in at ~21K miles and right under a year later.
To date I've done 4 oil changes, 2 previous with Rotella 0w40, 1 with Castrol 0w40, and currently it has Rotella again. I'm going to run the tests on the Rotella as well.
I use the larger diameter Hemi filters, either Purolator Pure One (gold) or Wix. The additional filtration might be the reason for the Blackstone Recommendation for a 9k oil interval.
I'm going to run the Rotella for about the same amount of time and see what I come up with.
