Oil analysis info seems to be scattered, so lets try to concentrate it here. I'll start; here's the Blackstone report (attached) for my 2017 diesel after the first 5142 miles on the factory fill oil. Mixed city/highway with a couple hours of light towing. I'm in S. FL.

Figured I'd add some of my UOA's
Soot levels are indicated in the comments and unfortunately previous soot values are not accounted for in subsequent tests
Original oil what ever that might be.

Now running with Rotella T6 5W-40; but no tests on it yet.

What is the latest tune update? How would one know? The last UOA test I had showed <0.1% soot for a 5280 mile oil.
I'm no genius. I made a mistake. I meant 5267 miles since my last test. Not 5280 miles. Now tell me how is my 0.1% soot level not a real number????
Well I'll try again.
The last oil sample I had tested had 5267 miles on it. The soot was <0.1%
My truck is a 2020 and has not been to Dealership in 2 years. Unfortunatley I don't know what version of tune update I may have.
Based only on the above info please don't tell me my oil test is invalid. Though I would be in awe if you could!
I was aware of that from the very first post. I believe I complied with his request. Yet he keeps insisting the results are invalid based on two numbers.
Not quoting from any BLACKSTONE report. I don't know where that idea came from since the original post was in response for test results NOT from BLACKSTONE.
I don't always use the same testing company and I haven't posted every test. If one were to look at the three tests I have previously provided (in post #218) one would see that the miles on oil does not match 5267 miles on any of them.
Instead of dismissing my results as invalid why not ask for clarification. As you have.

In addition out of curiousity I ran the same sample using Blackstone Labs. Unfortunately Blackstone missed the sought after Soot test.
Sample containers where held together while passed under the draining oil.
As has been mentioned previously fuel dilution tests between labs are different and results reflect it.
If you reread the posts you will see the problem starts with the seemingly erroneous assumption that I used BLACKSTONE.
The first response to my post was;
"Blackstone doesn’t use the proper testing methodology and nor is your 0.1% it a real number."
He doesn't actually say I used Blackstone but indicates my result is not a real number. Later responses kept referring to Blackstone testing.
I reposted a modified initial post hoping he would rethink his first response and ask the obvious question.
As far as this goes-
"If someone says "values from X are invalid" and the only reply after that is still repeating "my value is Y" but not saying it's not from X then...we end up here. This could've been avoided if you had provided the info on who did your test in the first place before all of this back-and-forth took place to finally get to the bottom of it."
We end up here because someone assumed Y is from X. This could have been avoided if he had simply questioned a false assumption and asked who did the test. You figured it out.
How does one conclude I used Blackstone based on the very limited info that I initially provided. This is especially concerning when the poster was only looking for non Blackstone results. I would like to know?

The last 4 oil changes were T6. The Titanium indicated prior to that was from the Castrol. The only other change in the past year that passes through the engine is a switch from Stanadyne to Hotshot Extreme as a fuel additive. I have also noticed a decrease in mileage between Regens over the last year, but I don't keep good track of that. It does show up as a slight decrease in MPG but that could also be partly due to a change in tires.
Only the last two tests where on T6 5W40. Prior to that it was all 5W30 which had lower viscosity and lower iron.
It would be interesting to see if eliminating the additive will make a change but I'm skeptical to drawing such a conclusion when there are so many other variables. However, I am running out of the Hot Shot Extreme and will make a change to something cheaper after the next oil change as I just passed 95K miles. I don't think I have ever used Stanadyne Performance Formula if that is what you are implying but I haven't used Amalgamated products before either. To throw a monkey wrench into the discussion, I had the previous oil sample (6/9/23) also tested by Oil Analyzers. Notice the high iron but the oil viscosity above 12.5 cSt doesn't suggest dilution. For some reason they did not update the oil as being T6 5W40 hence the comments on mixing. Nowadays I tend to look more at trends than any single test result but the iron has risen.
I sample hot from first 1/3 of pan drain splitting the flow over the sample bottles held together. A bit messy but the best I will do. The elevated iron aligns with the change in engine oil but I don't test every oil change. The switch to Hotshots Extreme occurred around that time but I don't keep accurate records on that. I was using Stanadyne Lubricity formula prior. It would be interesting if anyone else tested while using Hot Shots Diesel Extreme or any other solvent based additive that would support the theory?
