Does anyone have a UOA that can prove that a Wix XP actually filters 50% at 20 microns? I cannot believe that any fiberglass media would filter that poorly. If it did filter that poorly, wouldn't we see a huge increase in wear?

What parameter(s) of the UOA would you look at to determine filtering efficiency? As for your second question, no it does not appear to work that way in terms of a standard Blackstone UOA.

Does WIX publish ISO filtering results?

There was a member here who claimed that they had done testing at his work, and found this was due to a bad can design. He further stated that taking the filter element out and outtinf it into a better can resulted in much better efficiency.

If there was low test efficiency from a bad can sealing design I'd think WIX engineers would have wondered why it tested so low and investigate why.

WIX won't say anywhere on their website or by a phone call to their their Tech Line what spec they test to, they say it's "propriety information". Seems fishy to me.

I think that the 50% at 20 microns is misinformation. How can a fiberglass media filter worse than a fram extra guard? Look at fiberglass vs. cellulose under a microscope.

Not all synthetic media is the same. It depends on the exact design of the synthetic media.

Until someone can prove that a Wix XP can damage an engine, I will continue to use it and reap the benefits of an extremely well-built and free-flowing filter.

What kschachn is getting at is that it is arguable that a UOA will give you any information about what you are seeking to prove. It certainly wonít prove it.

With all the torn filters and other issues, this appears to be rapidly shaping up to be a hot topic for (how to quantify filter efficiencies.) 2018.

OH, and why donít you design a test to gain some information about the subject?

Looking at the microscope media pictures can be misleading. All is not so simple as it appears. Fibers of wood can absorb and trap molecule size particles. Think about a tree. Not only is it intriguing it is amazing, Also boring possibly. Not to me. I like botany. laugh

I like a blend of synthetic fibers and wood fibers, something like a TG has.
Not a popular idea here. OT
Not that full synth is bad, not saying that at all.

It's a free country. Others choose filters for the efficiency as being at the top of the requirements list, since that's the main purpose of an oil filer. grin2

And someplace in the grand scheme of thins the almost five percent more efficient filter is going to add a lot more life to the average car than it cost the person that bought them. Unfiltered debris cases added wear.

Do we know you with a previous user name? Just wondering as you sound like someone who used to post on here.

No, that isn't how it always works.

Here is an excellent UOA with a torn filter:

Yep, and every paper written on engine wear concludes that the cleaner the oil is kept the less engine wear there will be. A very basic concept to understand.

Yes so I say five percent cleaner equals at least 5% more engine life on average.
