Stainless steel oil filter ?

[TwoTrackinFool]

This is the second bike that I installed a Scott's Stainless oil filter . I recently had a little debate on Stainless vs Paper .


What are the thoughts here in ?

It's a preference I guess...no right or wrong!
It depends on how much cleaning and reinstalling you want to do, instead of removing one used filter and installing a new one.

Is it cost effective?

IMO, they are like trying to use both sides of the toilet paper, cleaning will get stuff mixed around to the "clean side", while paper you throw the dirty side out.

Also, 35um isn't that great at actual filtering, allowing many particles much greater than the minimum oil film thickness through...and again, some of those trapped will end up on the clean side during cleaning.

Pro?probably the best solution anti-static wise(as we know,normally oil filter are huge static electricity generator .(filter media etc)wich age the oil

The filter base is at GND potential. Do you want to use the moving oil (paraffinic insulator) to generate voltage to run your radio? I think the waxed car moving through air (insulated form GND but possible semiconducting tyres?) would Vander-Graff more voltage though.

Even the cheapest paper filter will do a better job filtering oil, the ratings on that are terrible in comparison. You also have to clean it out at each oil change. And I don't think it really saves money if you value the time you waste cleaning the filter and consider the high upfront cost.

What is the pro?

 

[sunruh]

do 20 oil changes and tell me the cost versus again.

now do 40

now tell me how a paper filter stops a steel sliver

 

[BigCahuna]

If you have steel slivers floating around in your oil, you have bigger problems then what type filter your using.,,

 

[ARCOgraphite]

good for racing.

 

[bepperb]

The math isn't that hard for the cost, but it really depends on how often you can change the oil. 40 changes on a motorcycle is a lot, for me that would be 40 years and is unlikely to take place.

A paper or synthetic media filter will stop a metal particle just fine. If you don't trust me take a look at what your OEM provides. If you don't trust them try a different OEM and see what they use. (hint... they all only use a stainless screen on their most inexpensive/basic equipment).

Basic filters at work...the steel sliver is bigger than the pore size of the filter, and the filter stops it.

If you are thinking of the piece of straw in a hurricane getting embedded in a telgraph pole, the thing that's required to puncture the pole is velocity...which simply isn't available in an oiling system...

Take an extreme 10gpm circulation rate, and a minimal 20 square inches of filter area...velocity through the media is about 10fps.

To simulate this, take your metal sliver of concern, hold it over a piece of paper and drop it from 2 feet, 2-1/2 inches. It will hit the filter at the same velocity.

Either still have a relief that allow unfiltered oil to the engine.

With a full roller/ball bottom end I wouldn't worry too much about how good an oil filter is....but cams seldom run in ball bearings these days, and that's where the damage will happen.

 

[rraiderr]

They look cool.

 

[sunruh]

well i could point out cold flow ability
or wont go into bypass
or wont crush
but that will just be argued as well.

so, yes, they look cool!

Conducting type of media is what you want,static electricity is what kill the oil and oil filter is basicly a capacitor for static electricity,so you dont want non conductor in oil filter (all else being equal)

Huh? What?

I bated yvon earlier, but he/she didn't bite

Non conducting filter media can build static, which can discharge and wreck oil in short order...with the amount of additive in engine/motorbike oils, it's probably never a problem.

But a metal gauze filter will stop it.



It's common, but hydraulic oil is very pure in comparison to what we use.

I Ty for the help,a lot of stuff i cannot explain ,but i cross reference with past experience and being 46 and a race techno fan my hunch is often close to the mark ,and with web i can correct misconception i have fast.the way i see it the ground need to be on the head of the engine so discharge happen in or close to the head.

 

[yvon_la]

If i had to venture a guess i would say some form of voltage in oil is needed to counter corrosion but i think synthetic cant do it because it is positive , so only one posibility is dyno but dyno oil performance is way lower .but then maybe the newer (2014)oil can have proper polarity to work in tandem with magnesium and calcium till we get x brand WITH GRAPHENE
