5k Oil Analysis Report - Updated 8/3/26: 15K report

[haohmaru]

Got a report back from Blackstone labs on my 2024. I did oil changes at 1200 and 5000. This is the 5000 report, so there was 3800 on the oil. I used Motul 8100 0W20 Eco-Lite.

Everything looks good, thought I would share it here.

12/2/25 Update:
I've attached the 10K analysis.

Oil was Motul 8100 0W20. I switched to Motul 5W30 when I changed the oil.
Things are still flushing out, even with the 2 previous oil changes. Oil was still good and could have been run longer. Don't plan to do that, just good to know Motul holds up, which I had no doubt of.

8/3/26 Update
I've attached the 15K analysis.

The numbers continue to improve. This was with Motul 5W30. I'm surprised the leftover 0W20 affected the viscocity as much as it did.

Very Cool, Love the Report. Thank You!

What did the metals look like on the 1200 sample?

looks like the engine break-in wear is significant past the 1200 mile mark. I just changed mine at 1k. I was planing to run to normal service intervals from here out. But now I’m going earlier on the next change after seeing these numbers.

How much does this cost? i may get in on this for my next change.

I didn't take a sample at 1200, just changed the oil and filter. I'll take another sample at 10k and probably no more after that unless I think something is up.
A report costs $40: https://www.blackstone-labs.com/products/

I plan to do an oil change every 5k, from what I've read, 10k is pushing it.

From what I can tell based on my UOA's from blackstone (two so far) the metals are still high after two oil changes. I do have a third sample I need to send off. Now, I'm not an expert at reading the UOA's so how high those numbers are vs the significance of those numbers of the overall oil I don't know.

They did go down quite a bit between sample 1 and 2 though they were still high on sample two. Just goes to show I guess how break in metals can linger. Again, idk how significant that is, but the thought of waiting 10,000 miles for an oil change after seeing those numbers seems like a higher interval than I'd like it to be, at least for cleaning break in metals, etc out.

At what mileages did you take samples?

At what mileages did you take samples?

2,400 and 5,900~

I was using Blackstone for many years. After having a conversation with one of their lab techs about my oil sample I decided to use another lab. The tech I spoke with didn't have an answer for anything I ask. The only response was, it depends, all engines are different. I thought the point of sending in a sample was to analyze how "my" engine/oil performs in reference to how I drive and where I live. Plus the fact the oil I had been using (M1 0-30 AFE) sheared to the lowest spec for 20wt oil and would show worse if it ran a little longer. Their BS rubber stamp statement actually suggested I extend the OCI effectively knowing the oil would completely shear out and below a 20wt oil. No thank you. My next oil sample will be with SPEEDiagnostix .

Post it here when you get it, I'm curious to see what it looks like.
