I guess what I am getting excited about is the dramatic difference between the Blackstone and Oil Analyzers fuel dilution numbers. I get they use a different method for calculation but one result might change my behavior the other I'd never worry about it...
I did compare to the other oil reports and the wear metals and everything else are very very similar or identical. Same oil, same mileage and roughly the same use case.

There are loads of T6 5w40 uoas out there between here, BITOG, PS.org, etc, I haven't seen as many 15w40 uoa's. Most are pretty boring (low wear rates), which is a good thing.

11,370 miles since my last oil change. I have to change the oil in my Flex and both samples will be sent in. The Diesel for confirmation on wear rates and longevity, and to see if the iOLM is correct, the Flex just to confirm the last numbers, I might reduce that to every other change as time goes on. Both changes are after the change oil now appeared. I think I have 5 hours idle time total since the day I got the truck and that is over 30K miles. Majority of driving is 60 MPH, all regens done at highway speeds and fuel dilution is unmeasureable every time. Trying to determine the OCA on the Flex, 6K seems a bit short for my driving, and using full synthetic too so 7K -10K would be optimal, I hate changing oil in the winter, which 6K happens to be every 3 months for me, with at least one oil change in the dead of winter. My truck so far gets one oil change per year.
