Did you see @wwillson 's internals photos after a 34k OCI?

I did, that thread was one of the reasons I went with HPL in all of my vehicles, even if I don't push the limits of the product, I still know it's one of the best options available. If I made the OCI interval based purely on logic and data, I'm sure I would be closer to 20k miles.

The Durango is 20k miles into another run. I'll get some more pictures soon.

I and many others appreciate what you are doing!

We have seen on this board highly extended oil changes cause deposit buildup, even with great UOA reports. I do wish I had a vehicle I was willing to risk super extended oil changes on, but this isnt the one to do that with.

We haven't seen this with HPL though. Wilson already chimed in so no need to call his experience up!

The deposits in my 2007 1GRFE were caused by a stuck PCV, not the xOCIs.
PCV was original until 2019 and 190k+ miles.
My bad, but it still runs like when I bought it in 2009

Makes a heck of a lot more sense. Thanks.

That is super helpful to know thank you, I have been planning to replace the pcv every 100k miles as preventative maintenance.

After putting about 100k on it, I made the mistake of trusting an auto parts store counterman who told me it didn't have a PCV.
I eventually figured out that it DOES.
