It may not make sense, but it just might be true. When I look up the Wix 51085 on their website, it says paper element. When I looked up something else, it indicated the "super-duper" media. This was several weeks ago. Hmm..I have 3 Wix 51085's in the carport closet, I'll look & see what the box &/or filter have printed on them.
Well, I asked Wix too. I inquired about the difference between their web site descriptions of paper & "depth" media and what was called "advanced filter media" on the boxes of 51356 and 51515 filters I bought. Here is their response.
"Both of your filters contain our premium blended, cellulose based media.
The cellulose is blended with high efficiency fiberglass and other man-made
fibers to provide excellent system protection. Depth media is used for
by-pass style oil filter systems and some specific applications for fuel
filtration in older diesel engines. Both your filters contain media that
is nominally rated at 19 micron. Please note, a particle that is 1 micron
in size is .000039" across. The diameter of a human hair is approximately
60 microns.
Thank you for your inquiry and your continued interest in WIX Filtration
Products.

The more I learn about Wix, the more I really, really like their filters.

today iam going to look at napa's 1372 filters and see if it says glass enhanced on the box..i will also look at wix 51372.either way ,i really like these filters
i was at napa and looked at my filters 1372 and it was not glass enhanced but the 1085 was..i went and looked at wix at g&s auto and the 51372 was not glass enhanced these were just cellulose media
This means that these filters trap 50% of the 19µ particles. Their absolute filtration (98.5%) might be something like 40µ particles.

these filters, according to wix, trap 12u at 50%and 98% 19u and 100% at 40u
The WIX saga continues.....I just went to the local O'Reilly's and picked up a couple of WIX filters: A 51036 for my LT1 Corvette and a 51522 for my wifes LS1 TransAm......now the funy part...the 51036 for the LT1 has a silicone anti drain back valve (red) and the 51522 does not. This one has only a black anti drain back valve, so I assume it is nitirle......WIX' web site list filter media as "Paper" for both.....what gives??

It's possible you got some old stock, as they changed to the red antidrainback not too long ago I believe. So the media is the same, just that you may not have the silicone adbv.
Thought you guys might be interested in this:
According to the Wix rep in an email reply to me today, all Wix filters now use the "glass-enhanced" filter media.

I inquired with Wix about 2 filters for my applications (98 Honda Accord V6, 03 Jeep Liberty V6). For these applications, the website calls for a 51334 and 51516, respectively. The website clearly shows "paper" media for both filters. (Turns out, the website is out of date...)
I asked Wix for media type, flow rates in gpm, and filter efficiency in um. I also asked about any filters they might manufactur with a "depth" type media (like Amsoil...) Here is their reply:
"Both our 51334 and 51516 part numbers contain our premium blended media, T03. It's absolute rating is 19 with a flow capacity of 3-5 gpm. Today's full flow oiling systems could not live with the level of restriction to flow a depth media would offer. Depth media is an excellent media for by-pass style oil filtration not full flow. Our T03 media offers the ideal blend of cellulose, high efficiency fiberglass and other man-made materials to protect today's engines to ensure optimum life when changed according to the manufacturer's recommendations for the type of driving you are doing - "normal" or "severe".
Thank you for your inquiry.

Interesting, in direct contrast to Amsoil's claims about "depth media", Wix made a pretty definitive statement about the "depth media." Question is, who's right? Wix or Amsoil?
In case you don't have Amsoil's claim handy, here it is from their literature about the SDF filter media...
"Traps Dirt Throughout Media Thickness
The AMSOIL SDF has a lofted fiber depth-type media that traps dirt throughout its entire thickness for exceptional filtering efficiency. It keeps oil clean and free of wear-causing contaminants. The AMSOIL SDF Oil Filter provides up to 100 percent more capacity and up to 20 percent greater efficiency than other filters provide. It is ideal for use with extended oil drain intervals."
Somebody's not telling the truth...

The K-Mart Castrol brand also had two lines of filters. The Castrol MaxPro in the white/gree/red box and the Castrol MaxPro Plus series in the black box. The MaxProPlus line clearly had the better filter media inside as indicated on the outside of the box....unfortunately they are no longer available at K-Mart as they are also going to "Code Orange" ........Orange alert!!!!
Depth-type filter media comes in two general thicknesses...just thicker than "paper" and the full thickness from the outer edge to the inner tube. Full thickness depth-type media clearly has too much flow resistance for full flow. Media just thicker than paper is fine for full flow and some folks can call it depth type. Toyota's Denso full-flow filters have fiberglass mat-type filter media that I measure as 2 to 3 mm thick. Is that depth type? Maybe so.
