Please decipher this for me. It's a Wix oil filter # 57502

Thank you50% efficient at capturing particles 6μ or greater.
95% efficient at capturing particles 20μ or greater.
It's "propriatary" ...I don't understand why they don't list the Wix XP micron rating
It’s no better than a standard Wix, it’s the warm & fuzzy feeling they get up selling you the XP.I don't understand why they don't list the Wix XP micron rating
I emailed wix about this a few weeks ago for the 51372xp and they said the xp is 99% efficient at 35 microns so i asked them whats the rating at 20 microns and their response was "if you want a 20 micron filter, try the 51372 instead" i asked again that i want the efficiency at 20 microns for the xp filter and they reiterated "Travis, the 51372xp is a 35 micron filter, if you want a 20 micron filter try the 51372"It's "propriatary" ...
Last time WIX showed it, it was 50% @ 20μ. If you call them, they will say it's "propriatary" ... that's what I was told. Maybe something has changed since M+H bought them. You should call or email WIX and see what they say now.
Why would you want a 35 filter 20 micron is better am I correct or my lost?I emailed wix about this a few weeks ago for the 51372xp and they said the xp is 99% efficient at 35 microns so i asked them whats the rating at 20 microns and their response was "if you want a 20 micron filter, try the 51372 instead" i asked again that i want the efficiency at 20 microns for the xp filter and they reiterated "Travis, the 51372xp is a 35 micron filter, if you want a 20 micron filter try the 51372"
The XP can run a longer interval and not get clogged.Why would you want a 35 filter 20 micron is better am I correct or my lost?
What WIX told you aligns with what O'Reilly Auto says on their website. But see the link below ... the independent ISO 4548-12 test showed that WIX XP was coming in at 88% at 35u and 62% @ 20u.I emailed wix about this a few weeks ago for the 51372xp and they said the xp is 99% efficient at 35 microns so i asked them whats the rating at 20 microns and their response was "if you want a 20 micron filter, try the 51372 instead" i asked again that i want the efficiency at 20 microns for the xp filter and they reiterated "Travis, the 51372xp is a 35 micron filter, if you want a 20 micron filter try the 51372"
The old Fram XG could run even longer than the XP, and at twice the efficiency. The new XG is still rated at 20K miles.The XP can run a longer interval and not get clogged.
Durability vs efficiency.
More alarming is the fact that the XP efficiency curve doesn’t make 90%, even by 50 microns-that’s really not acceptable for a “premium“ filter.What WIX told you aligns with what O'Reilly Auto says on their website. But see the link below ... the independent ISO 4548-12 test showed that WIX XP was coming in at 88% at 35u and 62% @ 20u.

I have this as a “watched” thread, so if you do happen to start a new one, could you put a note or link in this one to direct followers to the new thread? Thanks!! Yes, no problem I can do that.bobistheoilguy.com

Yes! I was just curious if there were any changes made to this filter since that test, also curious if they would tell me anything other than 99% at 35 micronsWhat WIX told you aligns with what O'Reilly Auto says on their website. But see the link below ... the independent ISO 4548-12 test showed that WIX XP was coming in at 88% at 35u and 62% @ 20u.

This might help you understand: https://www.donaldson.com/en-us/engine/filters/technical-articles/understanding-beta-ratings/Could someone explain to me how the micron rating works. I know the smaller the micron rating the better the filter. But that's about all I know. Also what does 90% of 50 microns mean? It sounds like it's only filtering at 90%, in contaminants of 50 microns in size.. but how can that be if the regular Wix does 20 microns. That means the XP is a s***** filter.
Efficiency of 90% @ 50u is just a way of saying that the oil filter removes 90% of all particles that are 50 microns and larger. So that means that 10% of all the particles that are smaller than 50 microns are going through the filter and into the engine's oiling system.Could someone explain to me how the micron rating works.
