Platinum is the one not up with the others.
It's being discussed here: http://www.bobistheoilguy.com/forums/ubbthreads.php/topics/3552644/7/Toughguard_vs_wix
NapaGold is the same as regular Wix oil filters.
They are close to Fram ToughGuard and Mobil1 Ext Perf oil filters in performance and filtration media type (mixed fibers). Fram and M1 beat it by a little we think. Wix just has these beta ratio tech items to look at, but not sure if its ISO 4548-12, and Wix considers it a secret.
You'd be fine choosing NapaGold-Wix oil filters. Good stuff. Not as good as Fram Ultra, but good enough for government work.

Best comparison I can find is on page 2 of this document.

I found this document in this 2011 BITOG thread when searching specifically for Mobil 1 filter efficiency data.
http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=2370608
It is reported as ISO 4548-12 methodology, at 25 microns, from 2007. As long as no significant changes have been made in media formulation by Wix it should still be representative for Wix and Wix made-fors (except the absent Wix XP / Napa Platinum). Note Microgard is now a Wix made-for and CARQUEST is now a Fram made-for though.

....It is reported as ISO 4548-12 methodology, at 25 microns, from 2007....
As noted the link is from 2007 and some of the information may have changed a bit. That would include the Purolator L30001 tested. That means that filter is in greatest likelihood the pre-Classic labeled (out late 08 early 09) version which was ISO test rated 96%@20um. That chart shows it being 99.6%@25um.
Using that anecdote information for comparison extrapolation, the Wix/Napa Gold 5/1515 on the graph indicates it being 98.2%@25um, it is very possible, reasonable and even very likely that the indicated Wix 51515 indicated beta of 95%@20um is accurate. And as frequently said 'a solid filter with decent efficiency'.
I will say an editorial aside, I've lost respect for some posting attempt to trash Wix/Napa Gold in a vain attempt to prove spurious hearsay posted of a much lower than beta indicated efficiency. Smacks of desperation imo.
So, thanks for posting and I'll continue to use Wix/Napa Gold with complete confidence.

What part of published information from Champion Labs throws it into the category of an anecdote? It does show ISO 4548-12 scientific methodology.

So as not to miss and/or distract from the most important and cogent points made, eliminate the one word of contention/irritation. What was meant was the few select filters tested for the ISO test comparison.
The main cogent points not quoted stand.
