If it's still break-in - hmmm. I hope it drops quick. Good point on the shearing - I may try to use something more shear resistant, but considering this situation may have warranty implications, I want to make sure my service dept is onboard with what I do/choose. Want to have them on my side, you know?

No aftermarket filter - car is totally stock. Minus consistent, painstaking detail work

Thanks, I'll definitely keep Dyson in mind.

For break-in I followed the manufacturer recommendations: During the first 1,200 mi - no full throttle, no more than 4,000 rpm, made sure to vary rpms/gears/speeds all the time, and avoided quick starts/hard braking. I rose above those limitations over time. But tried to be gentle overall until past 10k mi. single day of track wasn't until around 12k mi.

That's one of my top questions as well. I may consider asking them to reverse the changes, if able. For everyone's info, the ECU reflash was a manufacturer recommendation in a TSB due to valvetrain noise.

Haha. I could do a VOA on the Nissan Ester if a lot of folks are still interested - I have a half-quart open (~6 mos old)...

Good thoughts. Thanks - I hope it was just more initial wear. I'm definitely planning a short OCI (car sat in the garage all winter), and there was no track time last year, so hopefully you're right.

Didn't even know BSLabs would do a re-run. Good idea.

Understood - though I admit I don't know how much additional detail Dyson adds over the BSLabs report.

I'll keep fuel dilution on the list.
No mods at all - car is totally stock. The ECU flash was part of a factory TSB due to valvetrain noise.

That could have been the only thing to change ..and as another poster suggested, it might just be stuff kicked up from break in ..or some part of it.
Gary - yup, this was the first UOA with the Nissan Ester. I really hope you're right and it was just some later break-in. The engine's oil UOA history is as follows:
(1) factory fill
(2) Dealer Valvoline Dino
(3) Penzoil Yellow bottle Dino
(4) Nissan Ester Dino
