I have a 22 2500 purchased new Sept 23 with under 9k miles that like many has been experiencing very frequent regeneration. After the 4th trip to the dealership for this and multiple mentions of being overfull on oil they finally agreed to send in a sample. Now they claim this is “ok”

Frequent regen oil sample

I forgot to mention they means Stellantis engineers as there have been 3 star cases open. The last time it was in the shop for 2mo with no issues found.

How can they claim ok when they didn't even check for fuel dilution

My self I use Fleetguard/Cummins UOA kits, Blackstone maybe okay for a HEMI, but when it comes to a Diesel testing I use a Fleetguard/Cummins approved lab ( have yet to see a dealer say Cummins lab don't know what they are doing when it comes to oil testing and they use GC to test the oil for fuel) they cost less than Blackstone and you get TBN: https://www.genosgarage.com/product/fleetguard-oil-analysis-kit-cc2543/oil-filters

I would be inclined to have my own testing done through Fleetguard.

Dude there is a lot going on- coolant bad, fuel is likely high, lots of metals.
If you don’t make any headway, donyour own testing with fleetgaurd and get a lemon law attorney. An engine expert would easily rip them apart and this is a buyback candidate if your under lemon law. If not, keep fighting or sell the truck to carmax

Coolant in the oil is either head gasket or EGR cooler leak and either one of those is your regen problem. You should get a new engine and complete exhaust system out of that.
Check the transfer case and diffs to see if they have water in them. If they do truck has likely been in a flood. If the oil has enough water in it to make it boil, the potassium should have been through the roof high.

It was in no flood. I am the original owner and this problem didn’t start until until around 5000mi. Prior to that it was totally normal and fluid levels were normal.

I think you need to find a lawyer who practices consumer protection law if your dealer thinks the oil analysis is ok or anywhere close to normal. Any competent mechanic that saw that would tell you it has problems.
Theres multiple mistakes being made here.
Firstly, Blackstone…the worst place to send an oil analysis out when trying to determine fuel dilution. Blackstone does not use the gas chromatography method for determining fuel dilution. They use the flashpoint method which is much less reliable.
Secondly, if the dealership sent this sample out, it should have been collected using a Cummins OEM sampling kit, where the testing would go to Polaris Laboratories. Polaris is state of the art and is who Cummins Inc. uses for their in-house testing authority.
Thirdly, dealerships generally do not do oil sampling or analysis so there’s no telling how well the sample was collected. Did they respect the sterile container? Did they pull a sample from a container that had contamination? Was the engine oil warm / at operating temp? Did they sample the first few seconds when the plug was first removed? How long did the sample sit before it was shipped out? Did the sample remain sealed? Way too many variables here. I’ve been to a lot of dealerships over the years. I’ve yet to encounter one that had the wherewithal or the knowledge of oil analysis to trust with making / pulling a proper sample. The very fact that they chose Blackstone for a thorough analysis should be evidence enough to question the process and the validity of the sample.
I would absolutely draw your own sample and send it out for independent analysis using a Cummins OEM oil sampling kit. If you’re not sure how to pull a proper sample, feel free to shoot me a pm or respond back.
