I don't think I have seen a UOA on here of any D-A oil, so I thought I would post one I had done.

probably could have gone a little farther, TBN 4.46.
Good report.

Never heard of this brand. They've decided to use lower calcium & higher magnesium... Interesting. Was this a CK-4 rated oil? The sample looks good for the miles. Fuel is nice & low too.

Is this an E-350 or F-350? different applications for the 6.7L
Is the vehicle used for towing? Just curious.
Overall, not a bad UOA.

D-A was located in Indianapolis; have since moved up to Lebanon, IN. Not a big presence in the automotive market.
I once used their premium ATF (at the time a TES-295 PAO equivalent); good stuff.

Yes, it is a CK-4 rated oil. It's an F-350, and yes, it does a considerable amount of towing. Their Lebanon facility is actually where I pick up my oil. I had never heard of it until I started working for an excavating company that used it.

Given that this represents substantial towing, I'd say the wear rates are expected and doing well.
No contamination to speak of.
Looks good.
