25 micron reusable filter for evo

[leroyd92]

I found the specs on the cartridge for my stainless mesh filter. Mine is (filters down to 25micron) and the other type of filter says 30 and 35micron

Are there GOOD reusable filters out there? I paid $80 for mine and they jumped to $130

No cost is really worth my motor but if the difference between mine and a regular filter is lil to none I'd like to feel using it

We've been over this -- Motorcraft FL-400S @ Walmart for $3.97, or RockAuto for $3.37. You can buy at least 32 filters that offer superior filtration for the price of one reusable product. Stop the insanity!

 

[leroyd92]

I already have it, I've used it for 2 years now. If mine filters down to a correct spec I'd like To use it since I already blew the cash for it.

 

[sunruh]

32 is a LOT of filters.

say you go *real* conservative and only put 2k on each.

that 64k miles. a hair more than 1 year right?

Wix for your application carries a beta ratio: 2/20=6/20

In other words, 50% efficient at 6 microns, and 95% efficient at 20 microns.

According to your information above, the reusable product only filters down to 25 microns, at an unknown efficiency.

Think about it.

 

[leroyd92]

Now, that I didn't think about nor consider.


Are you looking at the 51412 filter ? OR is that the wix standard for Harley evos

Well that would be 100% efficiency at 25u.

The Stainless steel medical grade mesh used in these filters is rated on a absolute scale. It will capture 100% of everything 25u and larger.

From the work I do with this type of filter mesh a couple times a year at work, IIRC they filter down to about 5u(at ever increasing efficiency as they load up) in multi-pass tests for the screens in the 20u-30u range. It takes a rather large amount of debris to load them up to the point of bypass, enough that if you have that much debris you have other issues.

They unlike paper elements are not affected by water or coolant in the oil which can prevent the element from passing oil through it, clogging it.

Nothing wrong with these filters. Just different and different scares people.

These mesh screen filters are not all that different from a lot of screen type transmission filters in the pan. Don't see people getting their undies in a bunch over manufactures using those.

I was looking at my tappet screen and its as fine as can be. And the filter media I have is just as fine.

Idk, I'll have to sleep on it.

 

[rraiderr]

I had the scotts filter, it was well made and held up well.

I am just to lazy to clean them out, I would rather throw the old one away, put the new one on and be on my way.

Same with the K&N stuff.

That's comforting, given that modern pan filters average around 100 micron filtering efficiency, with older models significantly worse.

By "panties in a bunch", do you mean desiring better filtration? If so, you may want to do some research, as there are significant, proven benefits (cleanliness = increased longevity) to installing either a Magnefine or Racor unit on an automatic transmission.

Different doesn't bother me. Lack of ROI does -- it's the same reason I don't run a K&N air filter.

Your EVO is supposed to get 10 micron filtration.

There is no coolant in an EVO engine.

 

[Robenstein]

But you can get condensation in an EVO engine. Not the same, but my old Virago v twin was air cooled and I had warped elements from water condensation once or twice.

The thing with these re-usable/washable filters is the in washing them, you will be putting dirty stuff onto the clean side.

With my air filters, it's relatively easy to keep the water flowing in the direction that you want it to, and with one pass it's down the drain.

Washing the oil filter, in either a solvent bath or a parts washer, the recirculating junk will likely end up where you don't want it.

Unless the parts washer is fitted with (say something like) an efficient paper filter.

I've never had an issue cleaning them. Pre wash in one container of gas/diesel, and do a final wash in gas/diesel. Clean as can be.

IM only concerned about my screen element not catching little stuff and ruining my motor.

Soooo... all the transmissions rolling around that have accumulated a few 100 thousand miles with bearings, valve bodies and pumps with similar clearances as a engine have done so with with nothing more than regular fluid changes and a 100u filter. And people don't think a oil filter that is 100% @ 25u is good enough, interesting.

I do agree on the ROI, if one is paying retail, it doesn't often work in ones favor considering the cost of the SS mesh filters. It really has to be a filter that they could keep and use on their next, car, truck, motorcycle.... to help with the ROI average.

I'm merely commenting from a devils advocate type roll as I do have some experience with them. I have a couple of PurePower/K&N SS mesh filters that I got via trade work(not installed on anything at the moment, but have been in the past), regularity serviced some K&P filters years ago when I was still in the motorcycle industry and with my work now I have to do some sampling with SS mesh filters of various micron ratings a couple times a year. Oddly enough I have to sample the cutting oil on a couple of swiss lathes to see how "valuable it is", turning precious metals.

10u at what efficiency?

People like to quote the 5 micron and 10 micron spec of the EVO and TC filters, but the micron size is only 1/2 of the info you need.

You may want to look up the ASTMF316 test results on that so called 10 micron filter.

 

[Shannow]

People who are quoting auto transmisssions as proof that mesh works in engines (re-usable messh to boot)...

Transmissions breather imeasurable amounts of air in their many hundred of thousands of km, versus an engine with hundreds of tonnes of air.

An engine also consumes about 1/14th of the tonnage of air in fuel, and has some of each, and partially burned fuel/soot blow past the rings into the sump.

When a transmission filter is changed...it is changed, not washed in a bucket of slops and put back in.

To the proponents of the analogy, please explain how it is relevant again ?

 

[SteveSRT8]

Imagining you can see the contaminants in a bucket or a parts washer is a bit of a stretch. There's a lot of stuff in parts washers after a while, and I mean a lot. You don't want any in your engine.

These SS filters have been used for decades at the dirt tracks I used to frequent. But almost no one uses them anymore. They simply allow more particles through, in a pure race environment they are fine as we used to rebuild after every few races anyway...
