The Boss filter efficiency is 99+% at 25 microns last I checked. Somehow, not too restrictive either. Excellent filter.
This is correct. PurolatorBOSS is over 99% efficient at 25 microns.
20 Microns
Great video, thanks. I have been leaning towards the boss as my go to moving forward, but i haven't found a video as good as yours on it. You have helped me make up my mind on this.
Thanks for the review. The Boss filter is the only filter I've been using in my car!
Thank you !!! I been using Purolator Boss over K&N for a year on my b16a2 and I am happy
Purolator Boss is my #1 oil filter I purchase. I like Purolator's full line up because the build quality is excellent from their top of the line Boss but also for their basic red filter. That's really generous of a company to not go cheap.
One Ounce heavier will make the car Slower?
They claim 99% efficiency of dirt. This is meaningless. What 99% at removing 50 micron size contaminents. They do not cite the ISO test method, and their propaganda videos claims 600psi burst pressure which is meaningless, in a system that will never see more than 120psi.
Brian Sydnes They are great masters - pour the dirt into our ears
@@briansydnes1711 ..99% @ 25 microns for the BOSS filters, 99% @ 20 microns for the ONE, and 96.5% @ 20 microns for the original (red).
@@briansydnes1711 PurolatorBOSS oil filters are over 99% efficient at 25 microns.
Found the Bosch Distance Plus for $3 per filter at Walmart several years ago and I bought about 15 of them. Still using them. Thanks for showing me what the internals look like new.
Thanks for this comparison... from all the research I'd done, it'd come down to the Purolator Boss vs Bosch Distance Plus... this helps clear things up
I switched to Purolator Boss from Bosch on a whim after watching a Project Farm vid. After this, I am happy with my decision.
Great video(s), I have multiple vehicles and am a huge Purolator Boss fan. I have recently been doing a lot of research and have ordered everything for a Caterpillar engine oil filter conversion for my Duramax diesel. No real breakdowns of Cat vs ??? for the diesel boys. Thx and keep doin what you do!!
Been running Pennz U-P and Purolator BOSS in my nissan 2.5 for 205k miles. Zero burning, leaking or anything! Great filter and oil combo.
Great job of explaining the differences in oil filters.
Well done. Thorough and honest comparison
Thanks for the video that helps quite a bit I never realized the big difference between the filters
I use a Boss and Castrol Edge HM in my 09 Titan. Match made in heaven. Solid, solid filter. Subscribed by the way.
Thanks!
After using the Bosch Distance Plus I def noticed the oil was much cleaner, not as dark. You will def get more mileage out of the 99% filters which pays for itself.
Thanks, I've been looking forward to that comparison!
Super review, great job! 👍 Thumbs up!
Great informative technical video, I am a former Fram oil filter user running synthetic blend motor oil, and changing the oil every 3,000 miles or six months, depending on what the oil life meter dictated, but since watching your video, I am switching to (Purolator Boss), oil filter with Pennzoil Platinum full synthetic oil in my Chevy Silverado, 5.3 V8 with active fuel management, I have 27,960 miles on her, and I want to make sure I get all of the benefits my engine has to offer! Thank You for posting this comparison video!!!!
I have a Honda Civic, turbo 4 cylinder with 80k over 3 years of demanding city driving in Manhattan. I run Purolator Boss/One with Pennzoil Platinum in 5,000 mile intervals. The oil analysis I’ve done at 50k and 75k come back great.
How's the Purolator boss doing in your Silverado these days?
@@brianraabe308, Glad you asked, My engine has new Life, it has more pep, the gas mileage has improved dramatically, especially in town with stop and go traffic, I don't hear piston slap at idle. I am changing my oil and filter, once the indicator states the oil life is at 30%, and so far, NO ISSUES!!! i would Highly recommend switching, especially if the dealer is performing the oil change, Make your engine happy, and it will love you for it!!!!
My type of review very in depth 👍👍 thanks 👍👌
All these Oil Filters are Excellent Choices👍
I'm glad I found your channel, this is great info! I read a paper probably 20yrs ago from a guy who did exactly what you're doing. The conclusion from that was why I've been buying nothing but NAPA Gold oil filters since. I'd be very curious to see how that filter compares 20yrs later.
smokn05 thank, about same here, though use Royal Purple also,....
@@opera93 aren't Napa Gold under the same umbrella as Wixs and Mann? And I think Purolator also falls under that same umbrella but who knows the actual relationship between the companies and their manufacturing processes.
I use the Purolator BOSS filter on my 1986 Yugo GV car. I'm just that convinced it's a great top-of-the-line filter and worth spending the money for. Now I use it with Castrol GTX 10w-40 conventional oil and it work perfect for me in my old car that is a high compression engine. My mechanic use to tell me not to switch to synthetic because it will smoke and cause leakage.
Now I still use Fram for my car, but using their Fuel Filters. I try to find the older ones that were made in the USA and Israel instead of China. Sadly, they discontinued them altogether years ago, but I felt they were great for my car and try to stock up on them before they disappear completely of the internet.
You Need to use Pennzoil High Mileage Oil an Mobil One Oil Filter ✔️
FilterKingz I'd like to see a Wix Racing filter cut open. I always wonder what the difference was vs the other Wix filters.
Purolator Boss is TOP DOG in synthetic oil filters!
The Moto fixery All observations. No clear data.
very nice video, here is some interesting news, WIX filters bought out Mann-Hummel a few months ago.
This is not accurate. MANN+HUMMEL actually purchased Wix Filters (Affinia) in 2016.
Id also like to say the thick sides may make it easier to take off, i just bought an 81 suburban and the oil filter was stuck on tight and there was no room to get a normal filter wrench in, i had what was basically a set of channel locks for a filter and that almost didnt work because i crushed the old filter, if i didnt have the hand strength to crush deep for grip i wouldnt have been ae to get it off after crushing in
Ryan Ames you can always hammer a screw through it
I have been looking for filters with silicone gaskets. So far, the only ones that I have found are the Bosch DP, Purolator One (and extra fancy one on the BOSS), and the Premium Guard filters. Does anybody know of any other varieties? I'm just trying to consider all my options.
Dan, did you ever measure the length of the Bosch Premium filter media in this video and if so how long was it? Thank you.
I normally use the Bosch(DP 3312) Filters. DP on my Hyundai. And Premium(3330) on my 2018 Harley Sportster 1200. Never had any issues. I'm debating if I should try a Boss on my Harley?? Factory (Base) filter is rated for 40 Microns. The Bosch Premium is rated for 20. I have used the Bosch DP3300 on a 2015 Harley Street 750 since new. I like the Bosch. They're just hard to find locally.
Great series of videos. I'd love to see reviews on Motorcraft and Hastings filters.
Love your comparison videos. Because of this, I was glad I bought the Bosch premium for my sister's car to keep her car going. But for next time's oil change & my car's oil change. I'm okay using the Purolator one for both my sister's 97 Rav4 & my 01 Highlander.
My question is that amazon also has the yellow purolator that was the Purolator one color. But getting the yellow one is "buying 2" as the choice.
Do you prefer the yellow or blue oil filter for your car?
You may be referring to the old style Pure One filter we used to make. This filter was replaced by the new PurolatorONE Oil Filter in 2016.
That board on the by-pass valve looks like phenolic. I think the long name is Phenol formaldehyde resin and may still be used to make cheap circuit boards and other things.
how about haworth filters? used in truck fleet maintenance and will fit my '87 jeep grand wagoneer. I saw a cut-open video, and it looked pretty good. No one does oil filter cut ups like you, so I would greatly enjoy it. thanks.
Nice background info. I see why Purolator named their top filter "Boss" :)
btw, they have an M22 thread.
Purolator makes Bosch's filters for them. They also produce several other companies filters.
@Joe Shabiduyes Mann owns Purolator and Affinia Group but you are wrong. Purolator does have it's own manufacturing. Considering I worked for Mann and then the Purolator division I feel I know what I am talking about.
I would like to see a segment on cartridge filters that a many companies are turning to the look so cheaply made. Some with end caps some without.
Been using the Distance plus filter since my first vehicle, currently 2 of my trucks have front mounted oil filters so I like that it has a thicker can. Ever since wal-mart stopped selling the Bosch filter I've been buying them off ebay. Mainly watched this video because I'm looking for another reputable filter to replace the D+. The Purolator Boss looks like my next go to filter.
Wix
I would buy them at Rockauto if possible. I can tell you 1st hand there are way too many Chinese Knock-offs at Ebay now, unfortunately.
Hmm, would be interesting to cut open a red Purolator (such as your L14459) next to a non-xp WIX (such as 51334) and see how they differ (other than the WIX having the silicone ADBV). Now that MANN+HUMMEL is the parent company of both Purolator and WIX, and both are made in their respective North Carolina plants, I am willing to bet they will soon be one in the same. Since WIX standardized on the silicone ADBV, don't be surprised if the red Purolators start showing up with this! WIX from O'Reilly and Purolator from Advance. No more orange-can-of-death!
You should compare OEM filters for cars in the same class and engine output (i.e. Camry, Accord, Sonata, etc.).
th3k1ngofchina Honda OEM filters are made by Fram. No joke
@@jonsmith919 Buy the Beck Arnley filter for the Honda Accord… it’s the same as an A01 used from 2013-2015
So the red ones are good 3 to 4000 mile filter for the everyday driver correct?
I know this is 5years old, but what oil filter did you land out as the best as far as all your testing over the years?
What’s your opinion on the Purolator Boss vs the Mobil 1 Extended Performance oil filter? I’ve been using the Mobil 1 filter and Mobil 1 synthetic oil for several years but am thinking about trying the Purolator Boss oil filter. Thanks for the video!
I called Purolator and was told the Purolator One filters down to 20 microns and would be better if I change the oil every 5k. I think I’ll stick with Mobil 1 for $10 at Wallyworld. Thanks!
Have you looked at the hengst filter? I wonder if there any good?
Hey, No one seems to check out the Ecogard Synthetic filter. Curious where that one sits in the quality spectrum. Saw it online for under 6 dollars at Walmart. But it's over 10 on Amazon. So that's interesting. Thanks a lot.
Greg U go to rockauto.com I’ve bought Bosch filters for .88 before
I tried the Ecogard was a great filter. Now i have been getting Bosch premium. and Amazon 5w-20 oil. For my 2007 Honda CRV. Check the test on Amazon oil. some of the best for the price..
I saw a video someone posted showing Fram xg filters not having a metal screen attached to the filter media. And comments on that?
Yeah Fram dropped the metal screen from the Ultra line because it's no longer needed since they switched to a blended media for the Ultra line which offers greater media rigidity than the previous full synthetic media. The new blended media increased the filtration rate at the lower end of 8 micron size which is actually significant since that's where the particulate range starts that are associated with metal wear. I believe the Titanium line may still have the wire backing since that line is meant for extreme requirements and higher flow demands.
In your opinion, which filter has the lowest flow restriction? I have a 97 Caravan that is very sensitive to oil flow restriction and if I just use a generic filter it starves the upper end enough that the lifters tick pretty badly. For now I've been using the Fram HP3 which is actually a racing filter and changing the oil every 3k - it shouldnt make a difference but it does, even though I have good oil pressure. I just got the vehicle so I've been running seafoam though it to clean out the oil passages but its going to take time. Thanks!
DAH3313 buy a Napa one which is made by wix or Carquest brand which is made by purolator
the two lower 'grade/quality' filters are sometimes called 'tearolator' as the media has a tendency to tear at one or more folds.
right they all do like those no nane/house filter @ local quick change
My interest is the the anti drain back valve and by pass valve.
That fiberous material that you were in question of is called fannalic
Phenolic...perhaps?
It doesn't matter much when the oil pump gives out on you because the holes maximize pressure up to that point to get the equal volume flow. So you might see the same volume but the pump takes a beating and wearing out. Eventually there might be lower flow that will kill the engine. Look at the difference between these filters and the Racing filters, the holes are larger, The End! That's why I will use FRAM Ultra Synthetic from now on. Also to make you aware of the process of safely changing your oil. Always check the filters you use for metal shavings, check that the thread is clean wipe as much of it as possible, they are build by machines and you will always find metal shavings in a new filter. Clean it up and save yourself an engine.
Is the flow rate better on the Fram Ultra than the Purolator Boss ? I'm using a Fram Ultra right now.
The ownership changes hands like ones underwear. One thing for sure there are only 2 manufacturers in the usa, so of course they are similar.
I have questions do oversea brand one to
I would like to try the boss and top bosh
When referring to particle sizes in regards to oil filters, it is important to realize exactly how small the particles being discussed really are. Then, we can discuss the filtration effects of the filters in question in regards to engine life. There is a misconception when it comes to oil filters, that the smaller the micron rating the better the filter. Some companies rate their filter as a “5 micron” filter, which means the filter will catch particles microns in size with at least 50% efficiency. Let’s put a 5 micron particle in perspective. 1 micron is .001mm (or .00003937 inch), so 5 micron is .005mm (.00019685 inch). The tolerances in your engine will be no than 2.5 thousandths of an inch (.0025”). So, 2.5 thousands of an inch, which is equal to a 63.5 micron particle. A 5 micron particle is smaller than a human red blood cell, and too small to see with the naked eye. So how can a particle that size cause damage to your engine?
Next, let’s consider the purpose of an oil filter bypass valve. A bypass valve opens when the inlet side of the filter gets too restrictive. This can happen when the engine is cold and the viscosity of the oil is high (due to the weight of the oil), but this primarily happens when the filter media gets too restrictive or clogged. This is done to keep catastrophic engine failure from occurring; dirty oil is better than no oil. The lower the pressure relief rating, the sooner the valve allows unfiltered oil to enter your system. The last factor that contributes to the bypass opening is the amount (surface area) of the filter media used in the filter. A filter that has a high surface area is going to hold more contaminant and promote good oil flow for a longer period of time, so the bypass will take longer to open.
If the filter you use is 95% efficient at 5 microns it is going to remove more contaminants than a filter that is 3% efficient at 5 microns. The question is, how long will it take for those filters to load up with contaminant and enter bypass? The answer is simple, the more efficient filter will load up sooner, but at what expense? Oil flow is necessary to lubricate rotating parts, prevent engine failure, and help keep the engine cooler, plus again dirty oil flow is better than starving the engine of oil completely (the theory behind the filter bypass). Clean oil is best for long engine life, and a filter that can promote clean oil flow consistently for a longer period of time is a key component of any healthy engine.
When you are talking about filtration, whether it be oil or air, there is a balancing act that has to be performed to ensure your engine gets the protection it needs while giving your engine the most flow possible. Unfortunately, when the focus is an oil filter that is catching extremely small particles at a high percentage, the tradeoff is flow rate. This put the consumer in a “Catch-22” situation. Do you use a filter with the most efficient media at the smallest particle rating, and have the bypass open letting unfiltered oil through the system? Or do you have a filter that does not filter as small a particle size, but filters more of the oil for a longer period of time? K&N filters are designed to give you the balance of oil flow and filtration. Of course, we would like to say we have the most efficient filter at the smallest micron range, but the fact is we are not going to sacrifice oil flow or the quality of filtration by having a high efficiency filter that operates in bypass mode for 80% percent of its life. I know for me personally it’s a simple decision, the small particle filtration does not mean anything to me since we are talking about particles I can’t see, especially if there is a remote possibility of unfiltered oil touching my bearing surfaces causing premature wear and eventual engine failure.
When you are comparing filters, to make the most informed decision possible, look at the following things (with the least amount of emphasis on micron rating): Filtration efficiency, Filter surface area, bypass setting.
The KN-171 filter has a nominal micron rating of 25, meaning it will capture 25 micron particles with at least 50% efficiency. The filtration efficiency of the KN-171 at 5 microns is 3%. The KN-171 also has 165 sq.in. of filter area partially the reason it flows 25% better than the OE, paired with a bypass that opens at 14psi. The Harley Davidson filter 95.8% efficient at 5 micron and 98.6% at 25 micron, it also has 63 sq.in. of media and a bypass that opens at 10psi. This means the Harley filter will run in bypass mode for a significant portion of its installed life, whereas the K&N will allow oil to flow through the filter for a longer period of time. In my personal opinion, this makes the K&N filter the clear choice.
Here is a side by side to the amount of media inside of a K&N filter and your typical OEM filter (I don't think it is Harley's current one but look cool)
But K&N = larger particles + larger price. No thanks. P invented the oil filter 100+ years ago.
What's interesting is I usually can buy OEM filters for less money than most aftermarket ones... So I just used the OEM filters.
Filter Manufacturers will produce OEM for less just due to the visibility of doing original equipment with major car manufacturers.
They are not necessarily better performing.
I think Mann-Hummel makes the Bosch filters.
I've always wondered what relationship, if any, exists between Purolator Filters and the company "Purolator Courier", which I first noticed back in the 1980s when I saw their armored cars (as in CA$H) running around Detroit... I can't for the life of me figure out what oil filters have to do with armed guards delivering big bags of money...
There currently is no connection. The Purolator delivery service business was sold to a separate owner back in the 70's/80's.
Purolator used to make supertech Walmart filters. Now they are made by champion labs
i think the screwed up by getting rid of the texture
so out of all the filter comparisons done... what is your absolute recommendation... ever brand has its good one.. but whats the best of the best?
thanks for responding, in a different video the wix xl seemed to be the best one... do you think bosch distance plus is better than that one?
@@marcogeraldis7117 yes
I change my oil every 3.000 miles, I think any of them would work. Ford Excursion V10.
I watch the video from Ford boss may never mention one filter didn't have a pressure relief valve
In your opinion, what is the best oil filter you have come across?
SovL:Remedy purolator boss
Fram ultra synthetic
Is the Tech also made in America?
Ford Motorcraft please. Thank you for the videos!
Srt filters????
I'm responding now 4 years after this posting,(APR'23) and I"M NOT finding the Purolator Boss anywhere on E-Bay; the Bosch Distance+ is present. [But the 'Boss' is offered, but OUT OF STOCK via WalMart (12.50), along with the Distance+ ($24.95).
Look at Mobil 1 extended performance filter
Hyundai oem oil filter please
Thanks, again.. interestingly still looking for look at: **PERFORMAX “PO-167, “Oil Filters, etc. My **MOPAR dealer uses on my Program Oil Changes( Filters were LABELLED ,made “ in Mexico ! The last two filters “ MADE IN USA”, ***DIST By” SOPUS PRODUCTS, box 4427, Houston TX”((??)))*****..
Bosch Distance Plus is the best I ever used. I normally use Supertech or Purolater basic but I change the oil every 5 months or so. This Bosch kept the oil honey colored way past 60000 miles...probably took it out too early. But a pricey filter.
You forgot to compare the amount of miles they can handle. Thanks for the review.
Rani Mouf 5,000 is max oil change interval ever. Not worth risking your engine to save a couple dollars
@@jonsmith919
You thank truck company change their oil filters every week? No. They will last long if designed to do so
Change your oil every 5000 miles and it matters little what brand filter or oil you use provided the oil is the right grade. Synthetic oil does flow much better in sub freezing cold. In summer I do not think it matters much. Yes the more expensive heavier filters even yes Fram will filter better. Just do not let the oil get very black. Change your coolant every 24 months and transmission fluid every 3 or 4 years never flush and you should be good. Change that fuel filter often. 30000 miles. Cheers!
Yes you are right and wring but as long as you keep oil change intervals frequent, nothing much matters. Even cheap filters and oils from good brands are more than enough but i use synthetic oil and oil filter so that i can extend oil change interval. If i do the maths, two oil changes with cheap oil and filter costs as much as good quality filter and synthetic oil minus the time to do the second oip change. After this winter i am gonna try to use same filter for two oil changes i.e. 12k miles combined, i think its reasonable with modern day oil, filter and engine.
I was having my oil changes done for me. They used synthetic oil and assured me they used quality oil and filter. Well after 5k miles car started getting sluggish, hard starts, weird noises. My back got better so i decided to change the oil on my car and yes, it had the white purolator oil filter, it was beyond black. After using mobil 1 filter and full synth oil, the car felt better overall, no more hard starts,noises, etc. In my opinion purolator filters are not very good, at least the white ones.
Puro' BOSS, IS THEIR BEST!
purolator tests at 25 microns, it's on their website.
When has a oil filter with a metal casing EVER burst when installed on the specified vehicle??? Does a "stout" base plate on an oil filter affect it's performance? Instead of weighing the the entire filter, weight and measure what is MOST important... the MEDIA.
Try the pennzoil filter
They are garbage
Made by champion labs
Thanks! The Boss is the new top of the line however the P One was rated to the smallest particulate b/c they would tend to clog extended chage intervals hence the 10k rating.
In the forums a letter was copied recommending to not use the P One on motorcycles as bikes operate at lower pressures & the P one will represent a larger restriction + the bypass valve PSI on bike is like 3 psi lower on the bike specific ones. Lots of folks use the P One tho & another study still recommended the P One for bikes. I would agree if you use top synthetics.
I always used the P One in my cars/trucks. But as mentioned before I chose the less restrictive Boss for my XV950 Bolt b/c it flows better, is thicker (it sits in front of motor exposed to pebbles from frt tire) & it's nice & black.
Now, Motorcycle synthetic oil is another rabbit hole, one can spend stupid money for oils w/ the same additive pkg...
Hey, so if I have been using synthetic blend oil and now I moved to full synthetic oil, does that mean I need a specific filter for that type of oil or I can still buy Acura/Honda filter and be fine?
You can still use the Honda filter but keep in mind that the Honda filter is the low end Fram filter. I don't know how much you are paying for the Honda filter but for about $5 bucks you could go with the SuperTech filter which is a bit better than the Honda (low end Fram) filter. There's absolutely nothing special about the OEM Honda filter.
correction: hastings not haworth
Purolator Tech (white can) is made in China and is only a few bucks each; that's why auto shops buy them by the truckload. Not sure I'd trust it but I have no data to indicate any failures..... Purolator Basic (red) is made U.S.A. but is just a Tech with a red can........Interestingly, the PurolatorOne (blue) is a bit cheaper on eBay than the Basic red. ???
Apparently purolator has been having some quality control issues. Filter media being torn in manufacturing, the perforated tube in the center not allowing for any flow at all. I've read that these problems have been going on for quite a while without the manufacturer trying to fix the issue.

TRD is same as K&N.
N.A.P.A.
Boss
Purolator Boss is made in USA
Why so many people hate fram filters i have a simple answer change your oil every 5000 miles and any oil filter will perform the way it should simple as that
Would you be interested in opening up an OEM brand?
I don't see too much data/videos/posts out there about these: parts.subaru.com/p/Subaru__/OIL-FILTER--E089276/49227638/15208AA130.html
Mobil1's equivalent is the 104(A) which I saw you using earlier so I think it should fit fine in your vehicle?
Tokyo Roki is the manufacturer apparently.
Here's some specs I've found .. but no sources?
www.subaruforester.org/vbulletin/f113/subaru-oil-filter-comparison-99130/
Particle size is a critical value when giving efficiency numbers, according to any standard (SAE, ISO, etc.)!!! You can say "I'm 99.9999% efficient!", but if you're talking about stopping boulders or 12 pound chunks of aluminum, it is meaningless!
Also, the term "microns" is outmoded in metrology. You should speak in terms of micrometers.
The PurolatorBOSS filter is over 99% efficient at 25 microns.
Something tells me that you can buy the cheapest oil filter or the most expensive, best constructed oil filter and not notice any difference. Doing the same experiment with oil would probably only show very minimal differences over a couple hundred thousand miles.
There is big difference between the filter tiers, I noticed my oil was much cleaner with the 99% filters.
Maybe IF you religiously change oil & filter every 3,000 miles. And don't drive ever in dusty conditions. The same experiment with oils, would reveal VAST differences. Particularly in sludge formation. The cure for sticky valve lifters in the Isuzu Factory Manual is: "Use Mobil One oil" So great oil can cure problems CAUSED by bad oil, to some degree.
WRONG
GREAT. A PIECE OF THE POLYMER SUPPORT SCREEN BREAKS OFF... THEN WHAT? NO THANKS. I WILL USE THE ONE WITH THE STEEL SUPPORT SCREEN.
What many videos do not show is how Motorcraft Filters are one of only few companies using a thread end bypass, Wix, Napa, and Royal Purple all had outstanding design and when they got bought out, the designs changed and in my opinion they are a cheap design. No longer made with highest quality. Royal Purple Filters, Napa Gold and Wix have all changed from a nice steel base plate with thread end bypass, Silicone ADBV, evenly spaced holes and steel coil spring, solid canister casing. It would be interesting comparison how they have changed. Now Purolator is better than those. I currently use Motorcraft although I know they use a leaf spring and the Purolator is a decent design, the Boss is nice and it shows filter media is better than Motorcraft. Not a fan of dome end bypass. Many new oil filters displayed in videos don't even come close to what RP and Napa Wix used to be years ago. The new ACDelco E core is an embarrassment. Why do these companies think they can change a proven design and still have a loyal following for a cheaper product. They must think customers don't notice. I expected K and N to be higher quality, the dome end bypass design is cheap and does not look built with durability.
If we dont get the micron rating, this is all for nothing. 3 to 10 microns is what it should be, but many are at 20
Using the FILTERMAG set of Oil filter magnets will remove all ferrous metal particles from your engine, regardless of micron size.
The magnets get ALL the metal particles, and there's less friction in the cleaner oil.

On the other hand some companies will claim filtering efficiency down to 10 microns or down to 8 microns but they don't tell you what percentage at that micron size so that's just as useless as not including the micron size.
You
have not mentioned the importance of where the bypass valve is
located in the oil filter element !!! If this valve is located on the
reverse side of element, then during a cold start (when the oil is
thick and this valve is activated), the oil passes outside the filter
element, picks up some dirt that has accumulated on outside filter
surface, and again the dirty oil goes through the bypass valve !!!
But, if the bypass valve is located immediately at the inlet, then
the oil ( when the bypass valve is activated ) DOES NOT pass along
the "dirty" side of the filter, and all the dirt
accumulated on the outside of the filter element remains there
forever !!!
It would be
nice if the filter manufacturers indicated in the specifications
where the bypass valve in the filter is structurally located !!!
Purolator Boss is advertised as a 15,000 mile filter. Puroilator One a 10,000 mile filter. Classic a 5,000 mile filter. Tech is probably good for a little more. Low end filters by any manufacturer are basically no-name filter equivalents. All of them are good for 5,000. Lots of people hack that widely sold brand in the orange box featured in that ubiquitous box store. It's as good as any other. Stay within the design specifications of whatever product you are using and you will be okay.
Mobil One Oil Filters ✔️ ✔️
Purolator will again be making Mobil 1 filters starting in January.
I appreciate all the cut and posts! I’ve turned away from purolator made filters though because of the tearing issues. Mainly with the motorcraft ones that I was using. Fram is a much better built filter. And I used to be against Fram for no other reason then the internet said they were bad...
FilterKingz they have been known to fail and tear at the wide pleats. There are many documented cases on the Bob is the oil guy website. The pressure becomes too much at times and will tear the weak filter media. It tears at the weakest point which ends up being the one wide pleat right before where the media is joined together. All the pressure is going against one small section rather then multiple where the pleats are together more.

There is one example. There are many though if you search for failed purolator or failed motorcraft or motorcraft tear. You will find several examples of this very common problem that many don’t seem to care about. It was enough to make me switch.
Like the one in the Fram Ultra! It will help if there ever is a failure to keep bits of filter paper from being sent through your oiling system. There was a case where a guy with a 5.0 F150 had his filter tear and it went though the engine. Clogged the small passages and the engine died. Ford had to replace his engine. Luckily they warrantied it.
It was a motorcraft that failed. Here is the link.

40 microns are you sure about that that's large that's almost like a small grain of sand
Yup the Distance Plus is rated at 99@40 microns which is how they were able to achieve the dirt holding capacity of that particular filter but it kinda brings in to question why would someone chose a filter for the purpose of holding "a lot of dirt" when that filter is actually letting a lot of that dirt get right through the filter media? lol. Kinda defeats the purpose. Even the Boss would be a much better choice with it's 99%@25 microns but for that price range a person would be even better off going with the Fram Ultra Synthetic which is rated at 99@20 microns but when tested actually does even better than it's rating. Bosch's justification for the Distance Plus is how much dirt it can hold and because of that it doesn't matter that it lets through particulate size contaminants that are associated with metal wear. The thing is unless a person is driving hundreds of miles every day through a high intensity desert dust storm, there's absolutely no way that an oil filter is going to accumulate anywhere near the amount of dirt that Bosch claims the DP can hold. Cheap filters have a capacity of around 7 grams particulate holding capacity and higher end filters between 10 to 18 grams. If a filter gets anywhere near the full holding capacity during a normal oil change interval then there is something SEVERELY wrong with that vehicle and that owner has MUCH more to worry about than the actual oil filter because that engine is already on the verge of complete failure! So to sum it up, the Bosch DP makes no sense whatsoever when all factors are considered and is nothing more that a gimmick.
BRO SCIENCE !!!! only an oil analysis tells the real story
