that's very interesting.

I'm wondering, if it would be possible to build a simple "tearometer" that would measure the force required to tear, say, a 1/4" strip of the filter media.
A simple pull test would be very easy to setup and perform.

The key would be how the media should be prepped. Soak in an oil water mix or just soak it in water and then do the pull test.

Compare all the filter media with respect to pull strength.

The results might be interesting.

I'd expect comparative "dry" test to be well-correlated with "oiled". That is, if media A is weaker than media B when dry, it is likely also to be weaker if oiled.

I guess oil manufacturers have this equipment and perform such tests. They wouldn't share the results though.


I mentioned water because that would be worst case. Vehicles with short trip history may have condensation buildup that may not get burned off.

For reasons just like this, a simple pull test might not be very useful and correlate with anything real world.

This is funny because Wix does make some filters in Mexico, but not the sizes Walmart is offering (3593A/1334, 7317/1356, etc)

Also, Walmart omits the A from the part numbers that end in A (8A, 3387A, etc)

I was able to check out the supertech ST2. The ST2 has the combo valve so some of the Supertechs have dome end bypass and some have the combo valve depending on application.

The nitrile felt fairly stiff to me. I suppose that would be necessary to get the right bypass setting.

I think I may lean toward the separate ADBV and RV functions with blend paper.

A lot better as it turns out. This clip was from a a Honda Technical bulletin.

Wow, had not seen this Honda TSB before. And yet another data point lending itself to the veracity of the Amsoil ISO 4548-12 test of oem filters, including the Honda A02 oem. And confirms similar info provided by a Fram engineer regarding Honda oem filter efficiency .

As for new ST line, again same published efficiency spec as the current made for O'Reilly MicroGard filter line. So whether ProSelect/Silver, pretty safe to say same media as current MGL line. And similar to/same as Wix made for Auto Extra filters posted here. For a value tier filter line, looks to be a serviceable option. The topic ST9688 one of the more preferable ST choices imo because it specs a separate dome end bypass.

That sounds about right
Does wix have a line that doesn't uses the combo valve but does use a nitrile ADBV?

The ST, MicroGard, Napa ProSelect/Silver and Auto Extra are all Wix 'made for' filters. And not all the of those applications use a combo valve. Some like the topic ST use dome bypass and some of the the MGL, NPS, Silver and Auto Extra use Wix's traditional metal thread end bypass with nitrile adbv.

None of the Wix/Napa Gold automotive applications filters use a combo valve, and with very few exceptions use silicone adbv. There are a couple/few odd applications use a nitrile adbv.

Oddly I see many saying the new ST is equivalent to the NPS. But it has the exact same efficiency as the O'R MicroGard line, that many call equivalent to Silver. So NPS/Silver same as MGL, all Wix made fors.

What Fram engineer info do you speak of?
