Does anyone know what the specs for a WIX XP WL10010XP are?

As the title reads, does anyone know the full specs for the WIX WL10010XP?

It claims 99% efficiency, but at what micron rating? I can't find it anywhere on their site. AI claims it's 13, but I don't trust AI all that much.

I've been using the Fram Endurance filter, but their efficiency rating is for filtration over 20 microns. If WIX is 13, I may pay up for WIX, and switch out the Fram.

The main questions are, how much above 20 microns is the Fram, and is there that much difference between 13 and 20, if 13 is correct for WIX.

The Fram FE filters for the Pentastar are made in China, so, that's a minus right there. I still have one new Fram left, but I would chuck it if the difference between 13 and 20 microns is enough to make a difference in filtration.

Thanks. I've seen that add. It's the only one that states 13 microns I've found. You would think Wix would put that on their website if that is actually the real number for that particular filter.

Everyone wants to tout 99% efficiency. That number means nothing if 99% is when filtering pebbles.

It's like the Fram 99%, then you finally find out it's "greater that 20 microns". How much greater? 25%, 35%?

Everyone seems to try to hide information these days.

I will probably ask Wix. They want to know your whole life's story just to as a question on their website. That makes me think they don't want too many questions asked.

One thing I do know, they really like their filters by the prices I've found.

Search the whole bunch of sites on your filter specs and I’ve seen anything from 13 to 35 depending upon which site you look at as far as the microns.

Guess the best thing to do would be buy quality oil as in good synthetic oil maybe run some lubeguard biotech and also buy a really good synthetic filter. That’s what I do.

And I also don’t go by that silly oil spec analysis gauge whatever you wanna call it in the trucks that’s tell you when they think you should change it. I change my oil at least once a year or every 5000 miles and rotate the tire as well at 5000 miles. Just what I do, and all the above in my humble opinion only.

OK. I just got off the phone with WIX in Gastonia, NC.

They are telling me, and I had them confirm this twice, that synthetic filters have an approximate 35 micron rating. The high micron rating is what gives a faster/better oil flow on synthetics.

The cellulous filters have a micron rating of approximately 21/23 microns, and filter smaller particles better than synthetic media.

This was from the product support department directly.

They didn't know why Oreilly's had 13 microns on their website, and that it was wrong.

I guess higher micron ratings with synthetics is why Fram is vague when they state their efficiency is 99% above 20 microns. They just don't tell how far above 20 microns.

From AI....

AI Overview

Oil filter micron ratings are crucial for passenger cars to ensure optimal engine performance and longevity. Here's a breakdown of what constitutes an acceptable micron rating for engine oil filters in passenger vehicles:

• Standard filters typically aim for an absolute micron rating in the range of 25-30 microns. This means they are capable of removing at least 98.7% of particles of that size.
• For better or premium filters, a rating of 25 microns is generally considered appropriate.
• While filters with lower micron ratings (finer filtration) can capture smaller particles, excessively fine filtration (below 10 microns) may not always be necessary or cost-effective for standard passenger car engines. In fact, it might even restrict oil flow, especially during cold starts, potentially causing oil bypass and allowing unfiltered oil to circulate.
• Studies by the Society of Automotive Engineers (SAE) suggest that controlling abrasive contaminants in the 2 to 22 micron range is vital for minimizing engine wear.
• High-efficiency oil filters can achieve filtering efficiency of 99% at 20 microns or even filter down to the 1-2 micron range with bypass filters, significantly reducing engine wear and extending engine life.

It is important to remember:

• A micron rating alone is insufficient to judge a filter's effectiveness; efficiency (the percentage of particles captured at a given size) is equally important.
• Consult your vehicle's manufacturer recommendations or a professional mechanic for the appropriate oil filter and micron rating for your specific passenger car engine to balance filtration effectiveness with adequate oil flow.

The starting % of wix is not accurate, the media is so thin when an oil pump starts pushing fluid through it they become nothing better then a rock catcher. Look at the media.. Every wix xp I have seen, and I have seen a few, all the same, super tight thin media. See results on the bottom tested by a oil filter testing company. That company has no horse in the race.

If that 2021 chart is still relevant to 2025 filters, especially since Fram has started building their filters outside the country, with the Fram Ultra cartridge filter for the Pentastar made in China, I guess I will run the one China Ultra I have left, and the older Fram synthetic blend sitting with the Ultra.

I have a hard time trusting any chart over 6 months old these days. Too many companies cheapening their products every few months.

 

[Burla]

That is a test of the exact numbers, if you want you can test those numbers against what wix said their specs were at that time. You will find wix numbers are not even in the ball park of reality due to what I was saying.

I started running Wix XP and Redline 5W30 in my 3.6 pentcrap in the JK. That combo made the engine way more quiet. specially at startup.

 

[Burla]

That is the other legit question especially with hemi, though it looks like op has penn.. Does filtering spec matter? Because the good thing about rock catcher filters = good flow. I like the wix xp for my trans spin filter just for that, I more care about flow with that.

Plus wix xp beats any paper filter regardless IMO.

There’s been a few more YouTube filtration reviews since the one Burla posted was done. All similar results. I use the fram xg11665 filter.
