List of oil filters with 99% efficiency at 20 microns.

[The motor guy]

Who knows now that M+H is now owners of Wix. I looked at some of the regular Wix filters for a 5.0 Coyote today on the Wix website and it didn't show any Beta Ratio info, no efficiency info at all.

I'm calling Wix tomorrow about the XP, and I'll also ask about the regular Wix filters.

No telling how old this is but this one says nominal which is 50 percent. I was incorrect saying beta was 50 percent. I'm a bit rusty with this stuff, as it's been about 10 years since i've really been into oil filters. No telling how old this literature is either, but the 51515 is the replacement for the ford FL-1A

That one actually shows:
Beta Ratio: 2/20=6/20

Since Wix seems to define their own terms and formats, it's unknown if their saying "nominal" efficiency really means at 50% like normally done in the industry. I say that because the Beta Ratio shows 50% @ 6u. So conflicting info.

well you can ask tomorrow. Hopefully you can talk to an engineer and not the cute clueless 20 year old at the front desk that answers the phones.

I'm betting nobody calling them can ever talk to their engineers. So it will be cutie I bet.

I've gotten to talk to a few engineers before, surprisingly. I think the key is to ask a question they can't even reiterate to someone else.

 

[JohnnyJohnson]

I should be mandatory that efficiency @ 20 microns should be on every filters box. So it easy to make a decision easily right at purchase.

Some of these filters get too restrictive though.

 

[The motor guy]

How come my $25 fleetguard filter I just bought only filters at 30 microns absolute and now this $7 wix is claiming the same thing at 20 microns?

 

[ZeeOSix]

Not really, because the positive displacement oil pump will still provide more than adequate volume to the engine. Just because a filter is high efficiency doesn't mean it's too restrictive. The dP vs flow can be improved by increasing the media area.

Really I've been using filter with 99% plus efficiency since 2010 never having any issue on 5 vehicles with zero issues.

Brand name, please.

agree with @Kira I want to know who's been the lone holdout over the past 15 years in terms of quality and desired filtering.

Just got of the phone with the Wix tech line ... technically the M+H tech line (and says so when you call) since Wix is owned by M+H.

I was told the regular Wix filters are 50% @ 6u and 95% @ 20u (as their Beta Ratio indicates on their website).

I was told the Wix XP filter are 50% @ 21u and 99% @ 35u. This info is not shown anywhere on the Wix website, only the tech people have this info. So the 50% @ 20u of years ago still seems to stand today. The media in the XP is not the nylon meshed back synthetic media, but a cellulose blend with synthetic fibers (as shown by some WCW YouTube videos). Not what I'd consider "higher tier", but just a run of the mill oil filter with lower than average filtration performance.

So the XP is basically a rock catcher

A "higher tier" rock catcher.

Is u short for micron? 95% @20 microns isn't bad. Pretty dumb the xp version is worse though lol

 

[ZeeOSix]

Yes, "u" is for micron ... could also use "um" (for micrometer which is a micron).

Thanks for calling. “Higher Tier” than the Boss!

 

[The motor guy]

The regular wix is about as good as the fleetguard stratpore. Or nanonet, whatever it's called now. Ill have to look into those specs. I recall them being very good at giving efficiency rating at various percentages.

 

[ZeeOSix]

Thanks for calling. “Higher Tier” than the Boss!

I'd put them on the same tier based on both having 50% @ 20u efficiency. Maybe the Boss is a "tier notch" higher due to it's construction with the "SmartFusion" backed media, if that means anything.
