The XP is a wire-backed synthetic filter. Kind of like the difference between Fram's Ultra and TG lines
The XP is generally listed at 50% at 20 microns, and the Wix Gold is generally listed at 95% at 20 microns, so there is a big difference. A lot bigger than the difference between a TG & an Ultra.

So the Gold is better than the XP?
I thought XP was the big dog...
Just askin'...

I think Wix offers two oil filters: the regular Wix and the XP with the XP being the premium option ( "Gold" is not mentioned). So perhaps your micron ratings are reversed?

They're not, and it's old news.

The "Gold" is the NAPA version (NAPA Gold) of the regular WIX. No such thing as a "WIX Gold". Correct on the 50% @ 20 microns and 95% @ 20 microns efficiency specs.

The beta ratio for the 57151 is 2/20/75=3/12/17. Does anyone know the value for the xp?
I asked Wix, but they didn't directly answer the question. Cant find answer on Wix website.
So based on the above comments, the xp rating may be worse?
Thanks

WIX will tell you (as you probably found out on the phone) that the efficiency of the XP is "proprietary". Who ever heard such a thing from an oil filter manufacturer?
Before the XP efficiency became "proprietary", WIX was advertising it as beta 50% @ 20 microns on their website. Then they completely removed the beta data from their website.

That filter is shown to be 95% @ 12 microns and 98.7% @ 17 microns.
That's actually better than most of their standard filters which are 95% @ 20 microns.

There was a thread awhile back, the XP gets better as it progresses to the 15k limit; all things considered if you are not doing long drains greater than 10k, the "regular" Wix is a solid filter.

How was that determined ... did someone have ISO particle count tests done along the way? Got a link to the thread?

Thanks yeah I think that's the one. Plus, makes sense since as the media fills there will be more restriction.

Not all oil filters will become more efficient with use - I don't think any of them actually do, it's just that some filters don't slough off debris as much as others as the restriction increases.
More restriction from debris loading means more delta-p across the media to potentially break loose particles that have been caught in the media. This happens more so on the larger particles trapped in the media, as indicated by the graph below. Oil filters that test higher in efficiency are less likely to slough off debris as the media loads up because their ISO efficiency rating is the average efficiency over the loading period, so if the filter comes out with a high efficiency rating, then by definition it can't be sloughing off much debris as it loads up.
In the example below, the ISO 4548-12 efficiency test would rate that filter as 75% @ 20 microns (90% at beginning and 60% at the end of testing for the 20u particles).
