Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Reported cause
When you see a change, then that�s when a problem is noted.
Leading evidence: 'noted' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'noted' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check here' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

I also just installed the LN oil filter adapter so that may also introduce some variances.

A few things appear to jump a bit over the Mobil1 oil I replaced with the Driven.

Iirc Cat used to do them regularly, now we just prefer to get clean oil and filter in.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I received my first test results today and all looks very good, but there are a few values that are high and wanted to see what others thing about these specific values. Overall it looks really good.
Boron looks high
Calcium looks high
Otherise, all values are well within normal and better in all cases except the above 2 areas.

If you check here

it says they are additives which can greatly vary in concentration depending on the oil brand you use.
I would conclude nothing to worry about.
Test #2. A few things appear to jump a bit over the Mobil1 oil I replaced with the Driven. Assume that's okay given the comments but curious if anyone sees anything odd.
Base nothing from the first UOA after changing oils. You have cross pollination from the prior oil, and a bit of shock as well.
Until 2-3 services are done, you can�t gather any worthwhile comparative data from UOA.
Some of them do a sequence of tests between oil changes which can tell you more.

How does that work if changing from XP9 to DT40 between track events? If I am going from one to the other every change or two, is there no way to get good results?
You can get good results if you have your own trend data.. That�s what counts, how your results compare to each other as time progresses. When you see a change, then that�s when a problem is noted.
I laugh when people get one sample and act like it�s meaningful... It�s just a snap shot that�s not meaningful at all.
Sorry, it was 5w50 based on the old window sticker.
Hope to continue to run tests after each change over the course of the next several oil changes. I also just installed the LN oil filter adapter so that may also introduce some variances. From what I can tell, that initial test was a pretty good baseline - service records show mobile oil its entire life up to 37k miles. It'll be DT40 for a while to see how they differ.
Test #3 now in the books and all seems to be pretty good for a 15 year old engine. I've probably put more miles on this engine in 6 months than the prior owner did in 15 years, so I'm glad to see nothing is showing up that's a concern.
This is a source reference. Confirm exact model applicability in the original material.
