DONT KNOW IF THERE IS A WAY TO TEST FOR THIS DEFECT OF BYPASS VALVE NOT BEING FULLY SEALED ? kzbin.info/www/bejne/n6TKc6KAmd2Dbassi=dYPcz-3JSCkd7CPA

[@countryfamilyalways7280]

I was wondering if one thing to consider is the weight of oil used in the vehicle vs the restrictive flow testing you performed simulating 5W30 and 5W40 when hot I think it was ? For example my car takes 0W16 oil, so I'm thinking because of the lower weight or lower viscosity of 0W16 it would be "less restrictive " in testing for flow vs the ratings you got in your testing simulation 5w30 and 5w40. Am I thinking correctly on that ?

[@charleshines2142]

He seems to be a smart person but I don't feel that using lawn mowers and generators give everything a fair test. I have used Hot Shots Secret FR3 in my Nissan and I did notice a difference. His tests would lead you to believe that there was no difference because those lawn mower and generator engines run at fixed speeds typically. With the engine in a car the speed varies quite a bit and that is when you start to notice what difference there is if there is any at all. If you have bad luck just get some stuff that has a money back guarantee so you can get your money back if it turns out that you were right and it was just more of the same stuff. It is easy to become cynical with so many products being similar and then they are all just as mediocre. That is to say that _most_ of those additives that make miraculous claims are very similar and often seem to do nothing,

I am an HVAC business owner and Home Performance specialist. Filtration is huge in HVAC and you have to look at all variables. I have to say is that there are some very specific things you want to look at in the filtration world. In an ideal world, you want a filter that flows well, filters well and has a high capacity. You can't have them all. You have to pick what things are most important to you. The K&N AIR filters are free flowing and technically can make more power because they do not filter worth a darn. Same issue applies here. The Fram Endurance and Amsoil filters are identical filters made in the same plant by Champion labs. All the filters tested and shown at 10:20 are either made by Champion labs or Mann-Hummel. It's pretty simple math. The Fram Endurance and Amsoil filter nearly the best but the media is full Synthetic which filters really well to 20 microns and clogs fast. The question is how fast and how often should you change it before it hits the bypass or before the filter is actually clogged to increase oil pressure? I hate to say this, but if the data is accurate on this chart, then the Purolator BOSS wins pretty much across the board. Never thought I would say that. And before anyone gets their underwear in a bunch, think about the differences all over the table. I will probably still use the Amsoil EAO34/Fram FE3600 which are a different filter than they tested on this test. The Amsoil EAO filter product line and Fram Endurance / Royal Purple Extended Life filters are the 25k mile filters, not the 15k filter used in this test. For the most part, they are just bigger filters, and nobody should be doing 15k-25k oil changes anyways. Now I need to go buy two Purolator Boss filters that match the EAO34/FE3600 filters to cut one open and inspect new and use one for an oil cycle. Both of my personal vehicles recommend 10k mile changes, but we do between 5000-7500 miles, with various testing oils sent to Blackstone labs. I am putting together oil analysis between five vehicles, with different filters and oils. It just takes a little while to put miles on besides the work vans. Anyways, food for thought!!

[@jameszeiger8533]

Looking @ Purolator’s website, they are saying their Boss Series is a full synthetic filter media..good to know I suppose.

[@kentsouthers6244]

Your point about 20 microns "clogging fast" ... there's more to the story than just micron size. The amount of filter media, and the style of media construction can vary. Surface loading design vs. depth loading design makes a difference in how long it takes to "clog". Also more capture media surface area, means more contaminant can be captured, and still retain good flow. The PB seems to have more media and more pleats to go along with its smaller orifice derived from the synthetic media. As you stated "simple math" ... but, that includes ALL the math (i.e. surface area of the capture media, horizontal / vertical profile of pleat angles, etc.). Going by micron size alone isn't the only indicator ... as we can see by the performance diff's for similar sized (synthetic) media.

[@wayne9518]

Over the years I have often seen Purolator do well in these comparisons.

[@LynxStarAuto]

Purolator and Wix are subsidiaries of Mann+Hummel. Mann is the OE supplier for many Mercedes, BMW, VWAG, and other auto manufacturers. Filtration is the weak link in any automotive application. You shouldn't be stretching your intervals further than 7k miles. Especially if you have direct injection and turbochargers.

[@Unique377]

I disagree with your statement about 15k oil changes. I use amsoil in every car truck and motorcycle i own. In every car and truck I change my oil with amsoil at the 15k interval to include the amsoil filter. I have been doing this for over 10 years and never have i blown an engine or had any mechanical failures as a result! Even in my motorcycles my oil changes are limited to 1 year intervals or 5000 miles and my diesels 15k miles plus or one year. Now with that being said I have lotlgged millions of miles on amsoil oil and filters every fluid in my vehicles is amsoil to include all filters. I have broken down my engines and transmissions on amsoil they look as clean as the day they rolled off the assembly line. I have used the other oils filters and broken down those engines down to find wear sludge and all types of trash in the heads and lower end i have a keen eye for detail as I was a mechanic and aerospace engineer for 20 years so i and see a cheap gimmick a mile away. Amsoil simply keeps impressing me time and time again and believe me i go out of my way to find a flaw in the product and I have yet to have a single complaint other then the high price of the product but the proofs is in the results!

This is what is needed in this segment of KZbin. The guys who just cut open filters only goes so far. Seeing how they actually perform is the crucial information. Don't know about you, but im willing to sacrifice flow for filtration. Same with my air filter. Napa gold. Replace every other oil change to maintain flow. 10k for me.

[@brainkill7034]

I respect the Project Farm shoutout at the beginning. Not saying his tests are always the best, but really appreciate anyone that admit that their testing is not perfect and recommends people to do their own research and due diligence.

[@buckaroobonsi555]

That really depends on how you precieve the testing. It can also make the case for running the cheapest filter as well. Only the top performers where significant improvements and only in specific area's. They are always the most expensive and you still are not get a fantastic filter that does it all. If the engine is clean and well maintained and your air filter is doing it's job the oil filter should not be doing much. Especially if the oil is changed regularly and is a very high quality synthetic oil. You air filter doing it's job and not having any leaks in the air intake tract is super important to keep dust out.

But this is nothing new at all. Those things (filtration, bypass, quality of paper, oil analysis etc.) are in the textbooks since the 70's easily.

[@Austin-bc1yh]

This is definitely a game changer for me. I have devised a strategy to try and get the best of both worlds for tuner enthusiasts. After every oil change use a amsoil filter and drive it nice(because of reduced flow) for 100 miles or so to grab all the junk particles from the xp that barely filters then swap over to the wix xp filter and top off for your hard driving and high boost applications. A little more expensive but useful if you are trying to keep old german cars alive like those 1.8ts...

@@lucasfallert4031 Not sure exactly to what you're referring. Larger area means more flow, yes. But that only becomes an issue as the filter nears plugging. Most of the time, there is more than enough area to maintain flow. I ran 15k filters to 25k+ a number of times without issue. I figured they were the same filters, why not. I figured it was Amsoil being safe. They were good for 25k originally, why not later. Never was an issue in a Toyota Corolla. May have been an issue in other engines that shed more metal.

Filtration is exactly why I use Amsoil over the others. The amount of time an engine spends with the bypass valve closed vs open is why filtration is my most important consideration. Great testing!

[@BrandRanks]

Thank you so much for your support!

[@kentsouthers6244]

+1 for amount of time the bypass valve is open (cold) vs. closed. To go along with that ... if the oil is that cold, then the engine components are also cold (i.e. greater clearances), until things warm up a bit. One can get hyperfocused on the cold psi stat, but if you think it through, it makes a very small portion of time in the life of the engine that it applies. Also, if you simply allow the engine to idle a bit at start up, it is under a low load during this warming period. If it is THAT COLD, then you need to adjust your oil's Winter Weight (W) ... rather than use a filter that lets more contaminant through. Good to see Amsoil in (my) TOP 5. But, for those who don't want that much filtration, it's good to know that there are a few options that are only a little bit behind the Amsoil.

[@4doorSi]

@@kentsouthers6244 this is also why I use 0w-40 rather than 5w-30 in the winter. The 40 weight applies to the simple fact that I’ve got 245k on my engine and it loves to burn oil (it’s a Honda thing). It’s time for an overhaul for my engine.

Great video! Exact! It’s interesting that you said the Mann filter with 153.5 particle count at the smallest particle range was “impressive”, where Amsoil had a count of 6.9 in the same range! Now THAT’S impressive. The Mann filter had over 20 times more particulate in the oil! With daily driver cars, the rpm is only above 3000 for a few seconds until it shifts and runs steady between 1200 and 1800 rpm, so the oil pump gpm I would guess would run around 4 to 6, way below the filter bypass valve setting.

[@josimarruiz2]

Here is my opinion, do with it what you please. For the record this is the humble opinion of a physicist/car enthusiast. That is to say, do not trust me, verify what I say, if it checks out draw your own conclusion. 1) Particle Size Studies have shown (there are many look them up, Barris Marty is a good place to start) the size of particles which cause the most damage to piston rings and wear on the cylinder walls/sleeve are below 40 microns. If you want a quick explanation I can tell you that due to their lack of mass and propensity for overheating, they tend to accumulate on cylinder walls. Due to emission laws and the eagerness to improve mpg, manufacturers have lowered tolerances in piston rings, which further stops rings from dislodging the accumulation of particles on cylinder walls. Eventually these particles will cause wear on the cylinder walls and seize piston rings which leads to even more wear. 2) Oil Pressure During normal operating rpm, 2-3k, the oil pressure due to mechanical pressure is about 50-70 psi. Higher rpms and tighter tolerances can only increase pressure. Oil pressure is a good thing, it makes sure thar an engine is properly lubricated. The oil pressure is high in a normal operating engine, meaning that there is little to no pumping being done, at that point the oil pump is essentially a one way valve. Finally, 100% of the oil isn't going through the filter media, regardless of filter, at thousands of rpms the engine needs constant lubrication (specially engines using vvti and other variable valve timing engineering) and at thousands of cycles per minute the oil would disintegrate the filter media. The bypass valve during normal operation does not behave as a bypass valve, instead it is used to provide retardant pressure to force as much oil through the filter media as possible. In this regard the Mann filter is a complete failure, as it would essentially block filtration during normal rpms. If there is anything to take away from this video is that the Amasoil filter is the only filter which does what its suppose to do. Furthermore, the Mann filter has a needlessly poor design.

[@Athaion0]

what about the k&n which was similar and removed an insane amount of particles are 21-40 microns? this comment definitely gave a lot of useful info thanks

I would be interested in a size chart that notes which filters have identical designs but are different in length. I would then choose the tallest one I could fit in my car to get a step change improvement in each of your tests. In fact that would be a great next test: take a highly rated filter, and test it against the exact same filter but different length. Pretty please.

[@BrandRanks]

Great idea! thanks you for the suggestions. we still have several to go, but we will look into it.

[@marksullivan9954]

I would like you to test used filters. It is time-consuming to change filters on my vehicles. Years ago it was common to change filters every other oil change. Now recommendations are to change the filter every oil change. I am now changing the oil every 5K miles and changing the filter every other oil change. Testing used filters would indicate how often a filter needs to be changed. Your test rig is awesome.

[@arpadmiklos7339]

Well, the Amsoil may have a slightly higher flow restriction (12 vs 9-11 psi, hardly a major delta), but that's the only filter that actually filtered out 21-38 micron particles, the other three didn't do jack squat in that range. There's obviously a strong correlation here, if you don't filter, your flow restriction will be spectacularly low (hello, Mobil1) 😀

[@bbartlow0307]

If memory serves the critical micron size is between 3-5 (depending on engine) the distance between piston ring and cylinder wall. Larger particulates remain suspended in the oil or are caught by the filter. Point is, only an additional and restricted flow "bypass filter" removes particulates down to 1 micron.

[@briandenisefarmer333]

Loved this video! Really appreciate the great work you do on them. This is truly best way to test and understand a filter’s total capability! Just cutting it open and making physical evaluation that many people do on KZbin isn’t doing anyone any favors as to which is the best oil filter!! Great job !!!!!! Makes me confident in sticking with my Purolator Boss choice. I was thinking about switching to Amsoil filter but will now stay with Purolator as it is nearly as good with filter performance, better flow restrictions, and definitely more dirt/contaminant capacity!!

[@elpcmaster]

Damn right.

[@benjaminguider1048]

Thanks for taking viewer feedback to put Amsoil to the test. Fantastic data to allow different users to make more informed decisions. With Amsoil having the highest advertised micron rating, it's not terribly surprising to see it with higher flow restriction, imo. Then seeing it actually do the advertised filtering job was also good to see their claims backed up by testing. I currently run Amsoil filter on my 2015 Tacoma V6 and 2007 Accord I4. Seeing the flow restriction gave me some food for thought. Living in Auguata GA, I rarely see sub freezing temps. I think if i did live further North and regularly dealt with colder starts, I would be tempted to go with the Purolator boss. In fact, due to this series I'm considering switching regardless. Filtering is meant to prevent wear but if the filter is so restricted that the engine is oil starved, then it probably makes sense to have slightly less than the best filtering level to get that better flow rate. Great video.

Period. Thank you so much. Now, I'm hoping that you will also device a way to test oils (volatility, viscosity, lubricity, friction, cleaning power, etc.) and get results that can actually help in real life. Yes, I also watched Project Farm oil testing but those results (after a very careful analysis) were all over the place (since he was not using such mindful controlled testing as you do). His data is not too useful, except for getting KZbin viewers count, unfortunately. Your videos are truly useful in a day to day scenario, in a real life scenario. this is a certified hood classic

How things have changed. Years ago, FRAM fell from grace and became the biggest piece of crap ever made, they used carbon steel staples and GLOBS of glue to secure the pleated paper, the elements were breaking apart and collapsing, blocking the flow in the filters! I NEVER used Fram on my 69' Charger and Barracuda with a Hemi and 383, and neither did any of my dozens of friends who had high performance engines. Wix, Purolator and GM were very good back in the 60's-80's, Happy to learn that Fram got their act together once again and straightened out their mess. Great VIDEO !

[@linuxguy1199]

Interesting! Happy to finally see the K&N on the new tester, the K&N PS-2001 that I daily drive has a bypass design closer to the "Mann" filter's design, albeit it's unique but the entire body moves via a spring on the bottom rather then the traditional plastic thingy. I'm surprised more companies don't implement the design as a single metal spring seems to me to be a way cheaper solution then a plastic piece, another spring, and stamped sheet metal to hold everything in place.

K&N is one of the worsts on here. Glad to know. I will not be using K&N anymore.

Great video, I love these tests. As an Amsoil fan this was certainly interesting. You clearly demonstrated that the filter media and Amsoil is using seems to far ahead of everyone else tested. However the lack of capacity is concerning. Certainly driving home the point to never actually push these filters to their mileage limits. I do think that the Amsoil filter would great with Amsoil oil as that stuff somehow seems to flow better than almost any other I have seen as references by project farms videos and the fact that i myself have seen increased oil consumption or worse leaks from worn out engines when using amsoil vs other brands. While that sounds bad it really just points to amsoil being able to flow better and squeezing a larger amount of oil through very small imperfections or gaps. If you have a well maintained or new engine, this will result in less wear and better oil flow for bearings but in a worn out to very old engine it can simply make leaks worse or let more oil past piston rings and/or valve seals causing increased oil consumption.

[@daniellang6112]

Actually,Amsoil CLEANS deposits left by inferior oils. The esters in Amsoil rejuvenates most seals over time after having cleaned out sludge.

[@multiluxem2218]

To me, Amsoil SS is not a dedicated performance oil but it's an excellent daily drive kind of oil. Nice cold flow for cold starting and good cleaning capabilities, especially higher TBN. The viscosity is not very high but it's good for gas mileage. The price is also not that expensive if u have a membership.

[@oneninerniner3427]

​@@multiluxem2218 what do you mean the viscosity is not very high? If it's, lets say, a 5W30 oil it has to fall within the test parameters for 5W30 to be rated a 5W30 oil etc. etc. right?

[@oneninerniner3427]

​@@multiluxem2218 AMSOIL Signature Series oils surely are high performance oils. Like Amsoil says they are not for everyone, but are for those that appreciate and or need exceptional lubricants. For instance their Signature Series 0W40 is rated for Dodges with the high output engines like the Challenger that call for 0W40. And the 5W50 is speced for the Mustang and other high output engine Ford models. Then there is the Z Rod high zinc formula oils for hot rods & classic cars with flat tappet camshafts. Otherwise the Dominator Racing oils excell for hard core racing purposes. YES I am an AMSOIL fanboy and have been for over thirty years. I am also a small dealer only because I am a mechanic by trade and a retired amateur racer and have proven AMSOIL's performance to myself many times over. Ok?

[@multiluxem2218]

@@oneninerniner3427 Yes. But 5w30 is actually a range of viscosity (9.3 to 12.5 cSt @100C), not representing a single viscosity. Oil from different manufacturers can have slightly different viscosity despite having the same viscosity grade. The kinematic viscosity of some Amsoil SS is actually on the relatively thinner side within the viscosity range (such as 5w30), like many big brand oil. This is listed on their product spec document. Some other oil, like Redline, may have higher kinematic viscosity, despite they are both 5w30. It doesn't mean Amsoil SS doesn't provide good protection, as there are many other things can affect it, such as additive package, etc. But lower kinematic viscosity may help lower mpg and better cold start.

Best independent testing I've found. Would you consider doing endurence testing. I know it would take some time but would be very useful to the consumer. While any given filter might score well initially, what about simulating a time/miles test. Things like cold starts, sustained hot oil temps, pressure surges, sucking air from low oil uncovering pick up tube. I've heard of and personally seen the results of a failed oil filter. Things like seal blowing out, filter element coming apart, bypass valve sticking open or closed. My sone was driving a Ram 3500 diesel at a steady 70mph on the interstate with no load when the oil light flickered and the engine stopped. After a tow, the dealership determined that the filter media came apart blocking the inlet/outlet, stuck the bypass valve and blew out the gasket, then made a new gasket out of the loose filter media then ruptured the filter case and seized the engine. Ram bought him a new short block and installed under warranty only because it was a Mopar filter installed by the dealership.

I’ve tried several different filters on the same 2008 truck over the years every 5000 kilometres. For the past 3 ish years I’ve stuck with Mobil 1 because my engine starts quietly during cold Canadian winters. My engine is less smooth and louder (only on start up) with all other filters when it’s cold out. I would compare the louder sound I had as being similar to what an engine sounds like on first start up after having the oil changed. I don’t get that with the Mobil 1 at all, so I feel comfortable using that filter.

[@CaseyRobinson-p8i]

I think you should run this test again with the AMSOIL filter and using the AMSOIL Signature Series Oil. Because if AMSOIL designed this filter specifically for their oil (which would make sense) I would find that a more exact example. Not saying it would for sure change anything but just curious how different these values would be in that case. I have a feeling a lot of companies game the system to do really well on these standard tests rather than in real world applications.

Seems like the filters with the less restriction and better flow also . Seems like the reason Amsoil has the worst restriction is because it has the best filtering media.

Amsoil makes some nice bypass kits too you can put on any vehicle that filter out even finer particles.I'll take amsoil all day long for engine longevity. In fact my wifes Accent is almost at 230k miles and last Blackstone test using Amsoil oil and filter came back amazing.
