Yeah, the more I study this, the more I think I'll push just a bit further. I had hoped to make it to 50k ultimately, and may do so yet.

The great benefit to using one of these is that you could sample on some reasonable interval, and know how the fluid and metals are progressing along the way, rather than waiting to the end of a guestimated OCI.
I do have a Fumoto installed, have since 156k. I obviously use it to pull the sample at the end of the OCI, and intend to use it mid-OCI, but I've never thought of using it at the end, as a means of determining whether to unload the oil or extend the interval further. I'll definitely use that idea in the future.

I changed the filter this time at about 11k, and just shy of 25k, the first was a Fram PH9100, but at the 11k swap, I made the switch to a Baldwin somethin'or'nother (can't recall the number right now). I bought a case of those, so I'll be using the Baldwins for quite a while. There's no bypass filtration. My intent was for the FCI to be roughly 1/3 of the OCI but, as noted, the OCI remains a moving target. I don't doubt the Baldwin filter is a better filter than the Fram was, but having gone 25k+ with the Fram in the past with no failure, I'm not too concerned about the FCIs. I don't want to push 'em that far - filters are too cheap, but I'll change 'em when it's convenient and I've got some time rather than getting too concerned about sticking to a rigid schedule.
