I do know, a guy that has 450,000 miles and he's still using his oil filter, he usually changes his oil every 10,000 miles with synthetic I've never used this oil filter yet, I have used a Wix XP, and a Purolator Pureone. I did like the Wix XP, it was very clean when I cut it open, but it only had about 6,000 miles on it.. LOL

I doubt an ISO 4406 particle count is going to detect oil additives as particles with an associated size distribution. If it did, the ISO PC test would be too skewed by the oil formulation itself and be useless. The ISO 4406 test does not require a VOA particle count baseline as part of the test procedure.
It’s been my understanding that there is some contamination in new oil.
There's a few VOAs on this board with PCs. Obviously, the cleanliness of new oil will vary with oil brand depending how it's processed and filtered before bottling.
Here's the Contamination section in a "Wear Check" oil analysis report that shows the limits (the "Abn" column) for VOA PC counts.
Here's one example of a VOA with PC off this board.

Are you saying the guy has been using the same oil filter for 450k miles???
No he changes it every 10,000 miles.
lol ok
That would be scary, if possible...
For sure.
Fwiw, I received confirmation / clarification from a Donaldson filter tech rep just yesterday that verified for me that the P551132 oil filter is rated at 17u @ 99% efficiency (Beta 100 Per ISO 16889.
It, unfortunately, would not fit on the A25A FKS Toyota engine that I had hoped to install it on. So a Fram ultra was used instead. I am hoping to " clean up " some lingering break in wear metals by using an oil filter with a 20u (or less) @ 99%. And have "somewhat" bought into the hype of the Valvoline R+P, some added that today to my engine as part of my oil change.
Will be sending a VOS out for testing of this oil and sample again at 2500 miles to see what trends that the wear metals show. Already have done a 3000 mile UOS of the Amsoil Signature Series 0W-16 oil ( with Amsoil EA15K09 filter ) and am awaiting the results of the same oil sampled at 4713 miles prior to complete oil and filter change ( to the Valvoline R + P and Fram 4386 filter )
Car was purchased with 12500 miles on it from Avis and I didn't get a clear answer on any oil and filter change history. So I took the vehicle to a Toyota dealership to get the oil change done by them for free through the Toyota care agreement.
Won't do that again, considering the poor filtration that the YZZN1 stock Toyota filter does. Doing my own oil and filter changes from here on out.
Just wanted to pass along the information about the Donaldson filter.

Here are my results with the Donaldson, although a minor defect spotted.
Those look to be exceptionally good numbers for the various particle sizes. That was another reason that I had hoped to install that filter on my Toyota.
Thanks for your efforts and sharing your information.
Not at all. If no oil change and they're at 450K, thats the best oil ever.......

I took a look at some photos of the A25-FKS, there does seem to be a bit of face clearance on the filter mount. Did you try fitting it yourself or did the dealership attempt to install it? Some photos of the filter mount would be nice to see.
Anyways I would agree the filter did its job on the smaller particle range however if you read on in that topic a few new post ahead, there was a minor breach spotted due to one pleat bottom end being folded/crushed in the assembly process. Which is why some larger particles were caught in the particle count reading.

Here are some of the pictures that I was able to take of the filter mount.
I am trying to find a longer filter ( longer than the currently installed Fram XG4386 ). I have at least 3 more inches of length that I could use to fit a longer filter on to the filter mount. Just trying to increase the volume of filtered oil going into the engine. The current Fram filter sits on the mount with very little side clearance. If you look closely at the second photo, there is a faint line near the outer diameter of the gasket seating surface that shows the edge of the Amsoil EA15K09 oil filter that had been installed on the engine by me prior to this oil change.
And, to answer your question, I was the one attempting to install the filter. I'm not sure that I trust a junior dealership mechanic to try to install anything other than a factory brand filter. And I'm even nervous about that !

Looks like they made the mounting face diameter slightly smaller than their previous engine generation. Normally there is around 2mm of extra face radius from the filter seam outer diameter that would permit fitment of a larger size filter such as the Toyota YZZD3 & FRAM 3614 / 3600 size filters. I would suggest you measure that face diameter on your next oil change.
Here's a photo of the mounting flange face and gasket contact of an FE3600 I recently swapped the Donaldson out on. The gasket O.D. is 76mm which matches the outside radius of the 1NZ-FE filter mounting flange face.
I see, from the looks of the pictures the surrounding casting walls are very close to the mounting face outer diameter. The filter didn't spin all the way down against the face?

Hijacked thread
I wasn't able to get the filter to even start to thread due to the interference from the casting area surrounding the filter mount. The lip / seam of the Donaldson filter kept hitting the engine casting where it tapers into the filter mount. There appears to be a lot more space on both sides of the filter on the engine in your photos. My engine is the A25A FKS 2.5 liter.
