WIX XP 99% Efficiency at 21 Microns

Well, actually.


Filters designed for engines that have the bypass valve in the engine block do not have a bypass valve in the filter.

Yes, exactly. My oil filters for the Buick don't have a bypass valve in them.

Thanks ZeeOSix, You know your filters.

Well - it was worth a shot.

Do you have a spreadsheet of all the BITOG members you've played over the years?


I dunno. If someone (deliberately?) habitually posts wrong or muddle-headed info. in order to get a reaction (AKA trolling, I believe) are you being "played" if you correct it, or should you just leave it?

Someone might believe it, after all.

A dilemma.

Kind of like saying my Sonata is rated at 37 mpg, capable of driving over 100 mph.

The two are not related.

Ah but what if you posted it incorrectly and you go back and now you can't edit it!

Uh?

And I hope one day I can believe … having cut open a few XP’s the design and quality construction is truly there … So perhaps a change in the media could make this a top shelf filter …

Phone calls are nice, but they aren't proof of anything, that's why written contracts exist. People can and do say wrong things on the phone, a lot. It has to be from the company as an official statement. The fly in the ointment is Wix says it is their best filter and goes on and on about it in their literature. So apparently they think efficiency ratings are not that important, or the filter is better than 50%. Seems logical to me anyway.

So using the ISO standard+Wix XP in search … found several sites showing 99% at 35 microns …
Guess it might improve with miles … but don’t have that graphic depiction …

How important is 99% @ 20 microns? The O'Reilly site shows that the Wix XP is 99% @ 35 microns; besides the obvious 15 microns, what is the real world difference?

The reason I ask, it has been reported on BITOG that Toyota and Honda OEM filters are ~50% @ 20 microns, so it appears as though OEM engineers view flow equally important as filtering?

Purely anecdotal, but our (retired) 88 Camry 4 cylinder had just over 350,000 miles before giving way to rust and a rear main seal leak that wasn't worth fixing -- engine (and tranny) was original with mostly Toyota OEM (tiny) filters.

Wix XP appears to be taking the OEM approach that flow is about as important as filtering, especially for extended intervals. Curious what the thought process is with regard to that.

It's extremely important to ZeeOSix. There's no way you'll get him to run a Wix XP or NAPA Platinum. Not even if you sent him a whole case for free.

If it was better than 50% @ 20 microns, WIX would certainly say so. Give them a call yourself, their contact phone number is on their website. See what they tell you.

When is he last time you saw a company under advertise the performance of their products?

Don't know where the 99% @ 35u came from. If it's true then WIX Tech line should be able to validate. Could be 99% @ 35u equates to 50% @ 20u depending on the shape of the efficiency curve. "99%" sounds netter than "50%", so could be WIX moved the reported efficiency point to make it look better.

When I called them they wouldn't even tell me what test spec they used. I asked if it was ISO 4548-12, and they told me that information was "proprietary". Nothing proprietary about ISO 4548-12.

Ding ding. When it comes to marketing, if a company has "it" they say so.

... Yeah, why if there are more efficient filters available? I like less junk floating around in my oil, regardless if I can tell if my engine is benefiting from less wear or not.

Yeah, it would be funny to see the look on your face if a case of WIX XP/NAPA Platinum oil filters arrived in the mail at your home.

LoL, maybe good for stocking stuffers.

I would run one if I had to, but not by choice. At least they don't tear, which is a good thing.

This one is from bestmotoroilfilters.com … but there was a long detailed “sheet” on the frugal mechanic site and a couple others. This might be it and the 20u is only 50% …

re: 99% @ 35 microns. 4WD just responded in another thread with a reply from Wix.
