Would you believe that filter A is also an Ultra? Here is a particle count of an Ultra after 10k miles with exactly the same ISO code of 24/22/17 making it worse than the 99% at 40 micron Purolator Boss.

The one filter that has consistently showed good particle counts as early as 5k miles was the synthetic blend Mobil 1 filter which is rated slightly worse than an Ultra and Toughguard. It leads me to believe that a synthetic blend media is going to perform better in particle counts throughout it's usage compared to a high capacity full synthetic such as an Ultra or an Amsoil. There is data that shows both Amsoil and Ultras take about 15k miles before reducing particle counts in a significant way and there is data showing Mobil filters achieving similar particle counts at 5k (and maybe earlier).
Yeah, that's the one Ultra PC that a certain member would always latch onto for some reason. Go find more Ultra PCs and build up a database and you'll probably conclude like I did that bad PC is an out-flyer instance. Something went wrong there.
It is no more a one off than the one you latched onto showing an unusually good particle count. Like I said, I already looked at all the particle counts I could find. Not much data on the Ultra.
But the data on fully synthetic, long life, high capacity Amsoil showed it improved particle counts at 15k miles compared to a nominally less efficient synthetic blend Mobil filter achieving similar particle counts at just 5k miles.
