Discuss. I think I’ll change the air filter, it looked fine.

What were the oils for the other uoa’s?
I just bought a case of Kirkland oil I'm impressed with this report
That TBN being low would push me back to 10K intervals with a safety margin.
How old is the filter? Do you inspect it on a regular basis?
The reason I ask there is some theories that inspecting the filter introduces contaminants when you open the air box.

Wow, nice report.
I wouldn't change anything oil-wise. Keep running the same oil brand and same viscosity. Just drop your next Kirkland OCI to 6k and compare it to this one at 12k.

I ran many long oci's like this and everything was fine with the reports. Upon removing the valve cover I found heavy varnish and a very small amount of sludge so backed off to slightly shorter intervals. I do like to see someone not afraid to stick their neck out a bit.
Reviewing this latest run, lower # of days due to multiple long vacation drives. This is now my daughter’s car, we just used it for these trips. I drove and I run 70+ speeds for 3-4 hours at a time. I will do the next change closer to 10k, but will probably be a longer time interval.
Nice report. I'd just keep doing what you are doing. Now you know if something comes up at 12k and you can't get to the change, there's no need to rush or worry about it.
