What filter can't go 10K?

Agree w @Patman ... For me I'd ask how do you know how "any" filter did at a 10k run? We get visual inspection in almost all cases. My kids 12 RAV4 2.5 w FRAM orange cartridge looks fantastic at 6k and I'm confident it would look the same at 10k in this application. Doesn't mean it filtered well for the full 10k?? Or, does it? How to know with certainty?

How does a lowered filtration efficiency apply here as well?

The longer the OCI, the better it is to use a higher efficiency oil filter meant for long OCIs (ie, high holding capacity). They will keep the oil cleaner over the OCI. Filters that have a higher ISO 4548-12 efficiency rating hold their efficiency better as they load up. Oil filters do not get more efficient as they load up, that's been a long time misconception. Ascent's ISO testing show that phenomenon.

Most of the reason filters rate lower in the ISO efficieny test is because the media can't retain some of the captured debris as they load up and the dP increases across the media. Last thing someone should do is run a low efficiency filter for a long OCI.
 
I had a Royal Purple split at a seam on my 6.7 after 5,200 miles. In my experience, RP doesn't have what it takes. Since I found that, I've only used Donaldson on it
