PC RACING BLACK FLO REUSABLE OIL FILTER HARLEY TWIN CAM

[evostroker]

Anyone tried one of these ? .. looks nice..

We used a similar filter in an alcohol dragster, and it worked very well

yeap I got one and love it

The only thing I would be concerned about is ....HD Recomends 10 micron filtration 

• Superior Filtration ? 35 microns!

  110%, unquestionably without hesitation to the utmost degree!!

[TXChop]

Run one on mine for a while now. No issues at all. Motor still holding together too.

Is 35 micron gonna kill the engine? Isn't that like the size of a white blood cell?  Or not even visible?

Folks, these micron ratings mean absolutely NOTHING unless a collection efficiency is also specified at the stated micron rating.

If you work in industrial filtration, you will always get collection efficiencies stated at various particle sizes, and you will also get pressure drop specifications given too.  But oil filter consumers normally don't know these things, so oil filter manufacturers can get by with exaggerating things and not telling the whole story.  A 10 micron filter may only capture 5% of the particles at that size, but since it collects some, the manufacturer can claim it filters down to that size.  That 35 micron filter may capture 99% at that size, and may indeed have a much better overall collection efficiency.  Bottom line, nobody knows.

[Quad D]

Are there any companies producing a reusable oil filter that actually state a collection efficiency?  I'm wanting to get a more permanent filter as well.  I'm not a complete hippy or anything, but I do like to recycle and reuse what I can.  So are there any that really do as good a job as the disposables?

I use a PurePower filter and am very happy with it, it's made in the U.S. also not sure about that PC one it doesn't mention where it's made so probably not. That's important to me but maybe not to you.

A question for clarity:  A 10 micron filter may also collect 99% at the 35 micron size so the efficiency  is based on what is stated?

[Quad D]

35 micron seems to be the most common rating for these reusable filters.  And I would be sure to have a magnet, I can't see that causing any harm.

[Dan89flstc]

The PC Racing and K&P units look like the same thing.

[fasthog62]

what are you guys using to clean the filter when you change oil?

[Quad D]

I don't think the PC Racing filter has a magnet like the K&P units do, which would make it cheaper.

You need to get down to 1 micron before wear is nearly non existant. 35 micron is in the .001 range and can bridge the gap in some of the engine clearances. Scoring happens then.

I was looking at one of these units too. You can buy 12 H-D filters or 16 non H-D or 33 Supertechs  for the cost of the PC. No cleaning required, just drain and toss. For me that's a few years of riding. What does make me ponder it is if the ribbed aluminum housing can actually be effective as a oil cooler?

I use one, it is claimed 22 micron absolute, i would love to have smaller but at this stage there doesn't seem to be anything available. The thing with the normal 5-7 micron filters apart from passing bigger particles than you would think given the "5" on the box they can and will block to the point of bypass much quicker than larger rated types.
As an example in the mining industry we use high efficiency filters after component failures as an added precaution for a short time as even "clean oil" will block them, the filter housings have switches in them to let you know if/when they go into bypass, your Harley does not, a filter in bypass even temporally IE say if the oil is cold enough to resist flow, is not filtering anything!
If you are not comfortable with the larger ratings, as many are not, there are reusable magnetic strips you can buy that simply stick to the outside of your regular filter casing and trap some of the ferrous material in the oil, cut one open one day, many would be surprised! every bit helps.
In the end its up to the individual, early oil and filter changes will still give an engine a good chance for a long service life with of course the proper maintenance.
This is only my opinion with a little bit of experiance thrown in.

Yup, it has a magnet. Click on the informational box at the top.

True enough on the bypass thing but remember how long the oil was cleaned when not in bypass mode on the last ride. Don't think theres a ton of crap waiting to sneak through the engine when the filter is in bypass since the oil is already clean. Even on bypass there is some oil that goes through the filter media since the bypass is there to take care of the differential between one side and the other of the filter.
I'll take the long term cleaning effect of the 5 micron while cruising down the road any day over a filter that can only trap 30 microns. Not arguing, just stating my view. Keep in mind these engines will run with no filter at all and last a reasonable amount of time. Differences in wear only show up in the long term.

Thanks TROOP for setting me straight on that.    All this back and forth gets a little confusing and I guess everyone has their opinion and mine  don't count for jack really as I'm no professional and all I can run on is what I read on a site that tries to sell their product.  Or what someone else has as their view.  What I see is that 35 seems to be the standard most are running with on the reusable filters. I don't see a reason why this day and age we can't have a reusable filter that doesn't actually allow further damage to an engine.  I think most who would buy a filter like this would change their oil fairly regularly, other wise it wouldn't be cost effective at all.  I'm gonna keep my eyes out for an independent study or something of that sorts to try and clear this up for me.

One thing I've found is damn near undeniable (until someone gets senile....or high  ) is that experience is priceless for questions like this.  How many people have run these long term and seen the effects vs. a bike with out it?

[Hilly13]

Not arguing either Ron and respect your view entirely, just passing on food for thought, to which I will just add this, the mining company that I was working for had us all do a Caterpillar oil sampling and analysis course a few years ago, amazing the damage one little grain of dirt can cause, foreign particles in your oil have compounding effect, cleanliness is next to godliness.
Here is a thought, have a duel stage filter, first stage is stainless mesh and magnets, second stage a disposable high quality fibre 5 micron job, being as the stainless does not restrict flow very much you could theoreticly achieve a better filtration with no more restriction on flow than the Harley spin on.
My take is use what your happy with and ride those hogs

About the only way to clean oil enough to stop wear is to run a bypass filter system. Not to be confused with the bypass valve . It's a seperate 1 micron filter can that takes some of the normal oil flow and cleans this in a seperate curcuit and then dumps it in the sump.The regular engine oil filter remains. Not an easy task to do with a harley since the pump isn't likely up to the task in flow. Best we can do is drop the micron rating as low as possible which helps reduce wear. I think I read somewhere that dropping from 60 micron particals to 15 micron particals was about 70% wear reduction. I'm familiar with the compounding effect where a partical can remove some metal in it's path and then add it to the oil for further damage down the road. 5 micron will do the same but won't tear as big of a chunk out of a roller bearing or cyl wall as a 60 would. Taking all this crap into account it may not be a bad thing changing oil more frequently since all wear particals can't be removed anyway.
Read a mining artical on k&n air filters once where the ran a washable first and the standard paper second in a two element system. Object was to save money on filters. Ended up the second filter got plugged and UOAs were through the roof with silica. They went back to paper on the primary filter since engines cost more than filters.  I believe it was Caterpillar equipment. Have you heard of this?

Not with K&N but a few companies over here run fleetguard filters in the inner outer combo and have a wash and re-use system in place for the outers. That's on the big Cat, Komatsu, Hitachi, Lieber, O&K etc gear, there is a wash number limit as well as QA testing after washing, have seen some dubious returns over the years

[OneBlackFly]

what are you guys using to clean the filter when you change oil?

Kerosene and then Dawn soap, rinse well, and dry with old hair dryer.  Takes all of 15 minutes to clean my bike's K & P oil filter.
