Tells me they may yet have it but be backlogged as others have mentioned on here. (fingers crossed)
We will see....

I would encourage you to go with Oil Analyzers next time. They are much quicker than Blackstone, plus they provide TBN at no additional cost. Blackstone doesn't have the equipment to be an ISO certified lab.

I have that on my radar now. Thanks

If your under a MoPar warranty, as I was, when I showed the dealership and the MoPar rep. my Blackstone report over the past 70K miles, every 10K miles, they ask no more questions and replaced the engine.
Not saying Blackstone is any better, or worse, than another company, but certainly having that report made the engine replacement process a no brainer.

Just my $5 ($0.2 cents is so last year)!

Not sure if it has much value at this point, but attached is the final oil analysis on my engine that blew up. Took this sample just 300 miles prior to the engine being declared toast.

It is interesting to note that the EGR was replaced, per the recall, just 1300 miles prior to the engine blowing up. Fate or coincidence who knows. It just is.

The oil analysis doesn't look too bad, but it does show coolant getting into the oil. Something major happened in those 300 miles.

Well I guess the U.S. mail didn't lose my oil sample after all! Here is my latest O.A. that I sent in early Jan 23. Just got it back today!
All in all it looks pretty consistent, maybe high calcium?

Calcium is detergent. No issue there.
shorten the interval a little to allow some margin - it’s a bit thin! 12.5 is the limit for 40 weight. While not having any significant wear issues, you’re getting close to the limit on the viscosity. Maybe limit it to 6K to be safe!

excellent, thank you!

The EcoDiesel came factory with the 5W-30 spec, so I don't think viscosity dropping into the upper end of the SAE 30 range is bad. As we look at the major diesel oils (pictured below), they all drop into the SAE 30 range eventually. We've seen EcoDiesel owners running Rotella T6 for 25,000-mile intervals with no issues mentioned on their UOA report, although TBN was very low. I agree with @OhioTech that it is best to change oil when the TBN drops down low and viscosity starts to creep into the SAE 30 range, however, I think people like @OhioTech and myself take a more conservative approach to maintenance. It's quite possible there's still some good life in the engine oil.

I do my oil changes on a time rather than mileage basis since I don't put that many miles on the truck. This particular oil change actually went 14 months for me, I like to stay closer to 12 and will probably be more mindful of that! Plus Blackstone was correct as last year I did have a bunch of shorter trips this cycle. (taking care of an elderly parent who lived close by and needed lots of help). I am planning on sending a sample off this summer at a shorter interval.... 3500 miles or so to one of the other labs that has been mentioned to see what I get back.

I'm in the same boat. I'm very hard on my truck, which includes a lot of short commutes, towing, and idling. For that reason, I sometimes change oil early based on severe duty conditions. This is my oil change history:

I just got my first blackstone report. I changed the oil at 2k miles, and then this report was for the ~7,500 miles that followed that first early change.

Assuming this is for a 3rd gen EcoDiesel, you may want to post it here: (159) Official 2020+ EcoDiesel UOA Reports | RAM 1500 Diesel Forum
