Quit complaining.
No filter company is going to give you exactly what you want.
Do you think Wix wants you to know their filters aren't the best most efficient in the marketplace?
Do you think people really care who use them?
Did you ever stop to think that Mobils marketing department used the wrong language when they said their filter were 99.2%efficient at 10 microns? And then engineering stepped in and had them correct their website?
I caught Champ with a problem and had them correct something. It's easy to do.
I have said it before and i'll say it again...
Beta ratios are nice to have but unless you know the actual testing parameters, you only know a portion of comparison data.
Flow rate, add rate, termination points, are all at the discretion of the filter company or OEM who specifies a test.
There are NOT a standard beta test "specs" as some in here would love to have or think there are.
Which is why marketing types have the ability to put a best face on the data. Regardless of which filter manufacturer gives them the data. All filter companies do the same thing.
This is the full Q&A on Mobils website;
Does ExxonMobil make oil filters for use with Mobil 1?
ExxonMobil does offer a very high-quality oil filter that can be used with any motor oil, but it is an especially appropriate companion to Mobil 1. Mobil 1 Extended Performance Oil Filters contain synthetic fibers instead of the typical cellulose filter media. With a 99.2 percent efficiency rating (under SAE J1858 Multi-Pass Efficiency Test), the Mobil 1 filter is much more efficient than a typical oil filter, removing more particles per pass through the filter. In addition, the synthetic fibers in the Mobil 1 filter have less resistance to oil flow, reducing the potential for the filter to restrict the flow of oil to your engine.
------------------------
Multi pass means all particle sizes are used. You figure it out what they mean when the say 99.2% efficiency.
BTW..What particle sizes? Read for yourself:
