update purolator filters

[Robert]

I called the Purolator today and was helped by a very knowledgeable person about the new oil filters.  The differences in the oil filters from the pure one that we know are pretty significant. The yellow Purolator pure one is now the Purolator one the Purolator boss is a completely new filter. Both filters come with new filter medium and I will explain the differences.

 The Purolator one being equivalent to the Pure One filters 99% all of the particles down to 20 µm and then it  filters at 80% all particles below that. The Purolator boss filters oil at 99% of particles at 40 µm and 55 percent at particles below that most regular oil filters will filter particles at 85% below 20 µm. So the Boss oil filter will flow much better but is a fleece type of filter we see on the popular cars like Mercedes Benz and BMW plus some others. It is truly a 15k oil filter. The internals of both filters, such as the gaskets construction and seals are all the same as the Pure One we know just in a blue color. But the filter medium of both filters is completely different from the Original Pure One filter.

[AdrianR]

What he negated to tell you though that the new Pure One filter in the blue case is significantly smaller then the original (10) filter.  Again, imo, I thought the OEM Honda filter felt of better quality then the Purolator filter.  It was heavier and felt more sturdy.

Did they say if it is useable on a Goldwing motorcycle?

[Robert]

They say the same thing they always did.

they carry Purolator oil filters, but must use the auto oil filter #.
so that's about $4.50 per oil filter.

[Robert]

I am really surprised K&N does NOT give the micron rating for their filters. 

[F6Dave]

I've read the K&N oil filters are made by Hi-Flo.  Decent filters, but not as good as many others.

[Robert]

Just a comparison of the new and old Pure One and Pureone, exact same cans 14610 but different filter material.

[postoak]

Do our bikes use the same filter as the other Goldwings?  

So the, Purolator One has replaced the Purolator Pureone? And the Purolator Boss is their premium filter?

[Robert]

Actually the Boss is a 15k filter not the same filter medium as the other filters. Its a fleece filter much

like the Mercedes Benz filters, so not better just different. The micron rating is higher also at 40 microns compared to 20 microns.  

The Pure One has changed to the One and yes Goldwings do take the same filters as us.

I've used Pure One oil filters for years because of their top ratings and great price.  However, when researching the new line of Purolator filters I found reports of significant problems that began showing up in 2014, after their acquisition by Mann-Hummel.  Apparently there are many reported cases of tears in the filter media.  Some refer to them as 'Tearolator' filters.  Has anyone else heard about this?

I tried to do some research on this topic and found it was not the Pure One. I have seen a few of these cut open and the filter medium looked kind of pathetic almost like paper and it was not uniform in rows. I think it was the regular filters that this term was referring to.

I can say this thus far about Purolator filters...the better ones..  I have been using them now with all three of my vehicles, and more recently with my lawn tractor.  What I have noticed is simply the oil does not get as dirty, or as quickly as it did running Fram filters.  However, I decided to switch out the new Purolator filter yesterday on my Valk and replace it with the Honda OEM filter.  I think I will continue to run the Honda filters...especially after reading some goop about bike engines not having enough 'omph' , or oil pressure to safely run through the more constrictive Purolators..(thus better filtering).

I believe your are correct Adrian

I had both the new, blue Purolator filter in my hand, and compared it to the Honda OEM filter, and I 'felt' that the Honda filter was of better quality...However, this alone does not necessarily mean it is so.  Just an observation.

The link is for Blackstone labs not the oil filter tear. I think I found it from Bobs the oil Guy and it does not look like the Pure One I know and have cut open. Both new and old Pure One have many more pleats in them and thicker material so I am not entirely sure if that is the correct filter. Other than this one pic I have found no other Pure One tears and all of them are for the cheaper filters. I have used them on my 1500 for years and many Wings use them with many miles on the clocks.

 OP do you have a link to the Purolator PureOne model of oil filter that has this problem. It seems like all the links are talking about the Purolator classic (low end/cheapest filter.. like fram basic orange) they make.
The only Fram model that people do not like is their basic orange can... People like the TG and rave about the Ultra. Perhaps Purolator should be label the same. Avoid the Classic model.


Adrian just curious did you notice a difference with the filter that made you worry or did you change it to be safe? You posted just before me so I got my answer. We all have to use what we feel is the best for our babies.

I have used The K&N, Pure One, Honda OEM and the cleanest oil was the Pure One by observation of the color of the oil. I had used the K&N and wanted to see what if any change there would be in oil color since I was looking at the oil and thinking it was a bit dark. I did not change the oil and put on a Pure One and within 200 miles the oil had changed to a much lighter color. The K&N uses a finer filter medium that the OE filter so I would expect about the same results by using the OE filter compared to the Pure One. The only thing I see that may be a problem is the new Purolator One has not had the many miles or amount of users to fully test them like the Older Pure One. Which have had flow/pressure tests done to them on a Goldwing with comparison to a OE and a few other filters and no difference was found.

I have cut open the new Purolator One and its made with the same externals and same internals as the Pure One and the filter medium would be hard pressed to tell the difference between the two. But I can tell you its definitely not the one in the pic of Bobs the Oil guy. Its up to each to choose whats best for their bike. It doesn't matter to me but make an informed choice not a scared one.

The new Purolator One with the bike key next to it for size brand new never used



The OEM filter from the first change compared to the Pure One with about 3k miles on it


The PL14610 compared in height and filter area to the OEM Honda filter.


In the above pic you should also notice that the Pure One is glued on the ends to end caps that hold and secure the filter and material securly in the housing. It does not block any of the filter material at the ends or top and bottom of the filter like the OEM does. So actually the OEM filter has even less filter area than it appears. The material on the Honda filter is glued together on each pleat maybe 1/8 oif an inch down on both ends. The seals the pleat so the oil does not go through the ends and not through the filter medium. It also takes away filter area of about 3/16 to 1/4 inch of the filter. Yes this filter flows alot or oil but it does not filter alot either. I dont have the specs on microns but it has to be around 40 or more.

[Speedracer28]

Playing the Devils advocate here I will stick with the factory Honda filter. The filter material is much thicker/better quality and it also has a spring relief valve. The Purolator does not. On a cold startup, oil can be too thick to filter. To prevent the engine from starving, the relief valve opens when the pressure builds enough to force the calibrated spring downward, allowing unfiltered oil into the center tube through the top.

I have an oil pressure gage on my 1500 Valkyrie.  per manual should see 70 PSI at 5k rpms hot or cold oil.
using a super tech right now with Delo 10w30.  will see 70 PSI at 3k rpms until oil is warmed up past 150F and then 50 PSI up to about 4k rpm and then rise to 70 PSI. and still during shifts it will go closer to 70PSI then,
when I was using an oversized in diameter Pure 1 with 15w40 once oil got near 150F I would never see 70 PSI unless at 5k rpms it would stay at 50 PSI in the 3-4k RPM range.

Since the oil pressure port is after the oil filter, I think the smaller filter is going into bypass sooner than the larger filter is. I have seen similar #s when I have used OEM. Pressure is determined by the main bearing clearances.
This could be looked at both ways because of the pressure port location.
Thoughts?? Opinions??

A GL1800 owner on another message board posted results similar to yours regarding the lower observed pressure from the more restrictive Pure One.  I assume the pressure would increase if a tear develops!

I've read the tears tend to develop when the pleats are kinked near the glue at the top or bottom end.  That sounds like a quality control issue.  I've also read that any tears usually show up after several thousand miles of use.  It could also be possible that the more restrictive media of the Pure One puts extra stress on any weak spots.

I've been a big fan of the Pure One filters because they were so highly rated.  I have about a dozen on the shelf in various sizes for all my vehicles.  However, after reading about the tearing issue I plan to cut a used one open after my next oil change.

  I just ordered 6 K&N 204c chrome oil filters from Walmart.com for $9.06 each delivered to my local Wally world free. Look good and work fine. I change my oil every fall anyway cause I don't put a lot of miles on it.

[hungryeye]

I would stick with an M/C specific filter at least till the warranty ran out. Most of the better brands of M/C filters are made by the same company, Champion USA. The problem with Frame is that they use paper for the top and bottom plates that the media is glued too. Notice the dissected filters all have metal top and bottom plates, this is not obvious on Frame cartridge style filters (not spin on)where it is not possible to hide the cardboard inside the spin on casing. I would hope that Frame corrected this with all the bad publicity they been getting the last 10 years at least...

I think it is the smaller filter going into bypass sooner when oil is cold than the larger filter I use. after oil reaches operating temp, oil pressures are usually the same, except higher rpms smaller filter will hit 70psi a little sooner than the larger filter.

If you mean the bypass will open quicker because of the smaller filter area, then yes the smaller would bypass quicker. Oil viscosity would also make a difference and maybe that slight measurement difference is the difference is the restriction of the filter actually filtering better. To measure the pressure drop you would have to have a gauge before and after the filter. 

F6Dave you have only provided one example and a poor one at that of the Pure One filter being the culprit of the tears do you have any other? I Like you do have a couple of Pure Ones Yellow still around and dont want to use them if they are really talking about this filter. But of all the information I have researched its only been the regular filters. 

[Robert]

This is the article from the other board that tested these filters extensivly its not my work but I am thankfull for the test. It seems the results are no longer on the other board and erased although the text of the article was there.

 *****                                        *****                                             *****
        In reviewing the test data, it doesn’t appear that any brand of filter makes a noticeable difference in system pressures. While there are minor differences, I don’t see this as detrimental to the engine. However, I am concerned about how low the oil pressure is between idle and 2K rpm in general on my bike. It strikes me as too low. This may be an indication that the oil relief valve is stuck open and not allowing the system to build sufficient pressure at low rpm levels. I will research this with Honda and let you know what I find out.



        I will test the OEM oil pressure switch tomorrow to determine its trip value. I’m guessing it will be 3-5 psi which seems to be common in the industrial/commercial engine industry for oil pressure switches. While it is counterproductive or counter intuitive to have an oil pressure switch tripping the “Low Oil Pressure Light” at a value that might be well below the minimum required oil pressure for an engine ( which would be detrimental to engine operation) this would not be the first time I’ve seen a poor design of this type. They don’t call them an “Idiot Light” for nothing.


    Update 6-24-12
    I preformed several pressure drop tests on my switch using an accurate 0-15 psi gauge and it repeatedly trips at 2.5 psi.
    Yes..............only 2.5 psi. The OEM switch actually has the pressure rating stamped on the case of the switch. It is marked
    ".15" and I assume that is 1.5 bar. "Bar" is the metric pressure standard. This converts to 2.175 psi.


        During a cold start up, with the engine on high idle, the oil pressure does swing 2-3 psi at idle. This is due to engine speed fluctuations as it warms up. After the engine has become fully hot and the engine speed is more controlled and stable, the gauge pressure is much more stable. It varies only 1/2 psi at times and this ocurs only when I can hear a slight stumble and speed change in the idle. It drops 1/2 psi when the fans come on as a result of the engine speed drop. I assume the speed drop is due to the drag from the alternator. I don't recall hot pressures varing much at any steady speed except at idle. I check it again today.
        
    While I used very accurate equipment to gather the data and I tried my best to repeat and duplicate the test procedure as much as possible, trying to hold the throttle at a precise speed and read the pressure gauge is almost impossible. It’s easy to slip 50-100 rpm while trying to read the gauge and that does makes difference in the pressure value. That said, I feel confident my readings are within 1-2 psi of what they might have been if the throttle was held more accurately. So if you look at the pressure differences among the filters at any given rpm and consider my inability to maintain an exact speed while gathering a data point, the filters are very close in performance. The bigger pressure difference will be seen as they do their job and start to gather debris and plug up over mileage. I think this is when Purolator has a concern about using the Pure One on motorcycles.
      
      I have not spoken with Purolator directly as to why they do not reccomend their Pure One filter for motorcycle service, so I can only state what I think they are trying to convey with their warning statement. IMHO their concern must be pertaining to when the media becomes so fouled as to raise system pressure between the pump and filter to an extent that SOME bike engines oil system relief valve may begin the divert oil flow back to the sump due to that particulars bikes low operating pressure values. The micro filter media of both Pure One filters have the ability to trap a much smaller particle and therefore has the potential to restrict flow more than other filters that don't have such a fine media, over the same time frame period. I think it is evident from my test, that when all three filters are new (both Pure Ones and their motorcycle specific filter), the hot flow pressures are very similar and are of no real concern. I think Purolator’s concern is valid when two conditions are met. The filter becomes heavily fouled from usage and in conjunction when installed on engines with low oil pressure systems that can’t produce adequate pressure to overcome the additional restriction of the media when it’s heavily fouled. Most automotive applications use the same type of positive displacement oil pumps and systems that have the ability to produce 60-80+ psi of pressure. The wing uses just such a similar type system with similar operating pressures so I feel the wing is an exception to this warning. Some motorcycles that incorporate ball and needle bearings throughout use very low pressure systems in the range of 30 psi as a maximum pressure. I can see where this type of filter could be a problem for such an engine when its heavily fouled. Their oil pumps may not have the ability to produce the required pressure to push through a heavily fouled media and /or sufficiently open the filters bypass valve if the media is plugged. For this reason these bikes need filters with low pressure bypass valve ratings lower than the industry common value of 12-18 psi. Honda OEM, Pure One and SuperTech filters have a bypass valve pressure rating of 18. Mobil One and Bosch filters have a bypass valve pressure rating of 25 psi.
        
     So far I can't see a problem using a Pure One filter even though Purolator warns against it. Although I don't plan to pressure test all of these filters again once they have been in service for a normal oil change period, I will test the Pure One PL14610 again at my next oil change at approimatley 5K miles because it's the last one I installed and tested, so it's on the bike at this time.


Test conditions:



        Oil used is fresh Rotella 15W40 regular dino oil.
        Ambient temp 84 degree at the start of the testing and 93 degrees at the completion of testing.
        Engine will be at normal operating temp controlled by the radiator fans. Each test will commence upon radiator fan turning off. Engine oil temp was controlled by allowing the engine stop and cool down between tests.
        Engine oil maintained at “Full” mark on the dip stick upon each filter change.
        Oil temps were taken with a CD digital immersion temp probe, +/- 1% accuracy, held in the dip stick filler hole and suspended in the oil bath. The probe was not allowed to touch the engine case.
        Oil filter temps were taken with a Raytek laser temp gun, +/- 1% accuracy, directed at the end of the filter can.
        Oil pressures were taken with a 4-1/2” dial face Trerice #450 pressure gauge, with a sweep of 30-0-150 psi, +/- ½ % accuracy, dead weight calibrated at 75 psi.

At this point I feel any of the tested filters are fine to use without worry. The main thing is to make sure your oil and filter is changed at regular and reasonable intervals. I change mine on the wing at around 5K miles and will continue to do so until some indicator directs me to do otherwise. While I don't relish the thought of doing maintenance work (although I don't mind doing it), I'd like to be able to push my oil changes out to the book speced interval of 8K miles. Unfortunately the poor shift habits that start to creep in at around 4500-5000 miles using Rotella 15W40 dictates I change at that point. I'm not knocking Rotella because I feel it's a great oil for the money as it has produced some of the best shifting habits in my wing and in most of the other bikes I've owned. I know there ARE better oils that will give a longer service life before bad shift habits begin to occur because I've tried some of them. Oils like Mobil 4T Racing is one of these oils but it is about three times the price of Rotella, so I don't use it in the wing because I feel it's not cost effective to do so. Even though it does shift slightly better and for a longer period of time that the Rotella, it's better performance (in terms of longevity) doesn't justify the cost for me.

Great post robert
for the GL1500 oil pressure is 11 psi at 176F, 18 psi at 95F, my autometer gage shows exactly that, sometimes less, but that is the accuracy of the gage in the lower range. I would imagine the GL1800 would be about the same.

It's pretty simple.  Since Purolator warns against using their car filters in a motorcycle is reason enough not to use them while my bike is still under warranty...

However, the data as supplied tells a different story, never less,  I will remain on the side of caution.

The last time I looked at their website, Purolator also recommended their motorcycle specific oil filters.  I've used those in the past and they are an inferior filter.

There are warnings everywhere that are routinely ignored, like the maximum load ratings on motorcycles, or the warnings about using car tires.  Motorcycle engines of the past may have had marginal lubrication systems that couldn't handle much restriction.  But modern water cooled engines like Honda's flat sixes are much closer to automotive engines.  Heck, some of the 600 class sport bike engines have piston speeds as high as Formula One engines.  You can bet those have decent oil pumps.

I have over 300,000 miles on my 3 Honda flat six bikes, and most of those miles have been logged using Pure One filters.  I'm not concerned about the restriction.  But the possibility of holes in the filter media is enough of a concern that I'll cut one open at my next oil change.  Come to think of it, those holes would cure that restriction problem!
