Hi guys! Please keep in mind that I've made a mistake at the end of the video in the result table. My conversion from square cm to square inch is wrong.. by a lot. The correct value is 317.24 sq inch for Mann and 264.86 sq inch for Knecht. Sorry about that.
Salut Adrian, Knecht este deținut de Mahle, deci teoretic are trebui sa aibă caracteristici asemănătoare. Nu sunt sigur însă, o sa studiez si voi face un episod despre asta. Referitor la Hengst, inca nu le-am testat, dar o sa urmeze si ele.
Great Video! Knecht and MHALE are the same company. And people do not change your oil every 50 000 km, like your manufacture says. There's nothing bad to put new filter and new oil every 10 000 or 15 000 km. Greetings from Bulgaria 👍
Apart from the content which looks professionally carried out, l really like that you don't have unnecessary pauses or too much unnecessary talk to lengthen the video. These two combined make your channel one of my favourites
Wow, nu-mi vine sa cred ca asa ceva se intampla in Romania si ca exista oameni ca tine care fac o treaba profesionala la nivel de 7 stele, jur. Bravo si felicitari pentru munca depusa, motivatie pentru toti ceilalati sa fie profi in ceea ce fac!
Romanian people are good my friend, I worked with many from 2010. Unfortunately thanks to the BS which is Brexit, many left to go back to Romania. Good for them, sad for us.
Fantastic video! I really enjoyed the oil test videos as well. Great idea to go for english on this test as I am sure the english speaking audience also appreciates the utility of your tests. Hope you make more videos like this!
Ai devenit un pionier în lumea testelor pe RUclips. Foarte detaliat și informativ. Ține-o tot așa! Produci material calitativ și sunt sigur că mulți sunt interesați de astfel de teste.
Both are great filters and also OEM for VW/Audi, usually one of the two, on newer Audis you can find that it came from the factory with Purflux filter, but then again, it depends on the engine type.. Actually no filter is 100% efficient so whatever you pick, you made a good pick, compared to some no-name junk or fishy brands, this is top of the line. I've seen cheap filters that had more glue inside than they had filter material xD.
Parcă testul acesta este mai aproape de realitate decât cele cu uleiurile. La ulei este greu de reprodus ceea ce se întâmplă în motor și analiza de laborator rămâne baza pentru a judeca un ulei. Dar aici la filtre testul mi se pare ok și poți să continui! Mii de felicitări pentru munca ta!
I work in the automotive filtration business as Head of product management. Today still in the company as global manger of lean manufacturing. Nice idea for the test but i a sorry to be critical regarding the test so few comments: 1.Testing without a particle counter cannot support you claim regarding filter efficiency. 2. Your test parameters and table of comparison are not good and not relevant. 3. The pumping force in the vehicle is high and the gravitational flow test at 100 degrees Celsius does not mean anything it just gives basic parameters of the filter media which is irrelevant to the application in most cases. 4. Your comparison of visual structure of media between Mann filter and Knecht filter is also wrong. 5. Even though the test is done the same way, there is no way to assume or predict the distribution of your contamination sample in the same way as per fluid dynamics, so either gravitational test for retention or particle counter for efficiency at a specific @micron rating distribution sensitivity at the downstream end is the only way to compare. 6. We cannot know from you Video if the filter was installed in it's housings the right way or the same way in both cases (torque, o-rings, etc.) 7. Doing the test in proper ISO standard laboratory will change results dramatically. 8. Filtration area calculation is wrong. 9. the table of comparison is choosing the wrong parameters to force declaration of the Knecht filter as the better filter, which may not be the case if tested in the way i mentioned above. 10. From the test you did there is no scientific way to determine which filter is better and what is presented here is just your interpretation. 11. Checking 2 aftermatrket filters without reference test to the original equipment filter is a wrong comparison. they both can be better from it or not.
@@Zeghetank I would if it was possible but the equipment required for such demonstration is worth millions + the time it = unrealistic. Listen, the video is cool, no doubt, but the way the conclusions are reached is wrong and most probably so are the conclusions. The most fundumental problem here is lack of particle counting with known accurate count of beta ratio at specific micron ratings as per the standrd. But this is not the only thing missing here. It is totally not a correct method to view and determine the efficiency of filter media by optical view. it's just misleading the observer and he viewers of the video. Even a gravimetric measurement is acceptable for efficiency also for Dust holding capacity. Please note i am a product manager in filtration for automotive. My only interst is to alert that the results of this video as presented can be off and most probably are. I am not related to any aftermarket brand by the way.
@@BusterDescoperaRomania This is not acuurate. Sometimes it might be ,for example if the AM is the OEM and the filter is just in a different costume, but most of the time there are some margins. I worked with all brands and familiar with technical sepcs. all AM filters are not matching OEM design or spec, materials, etc, this is far from being the reality. Sometimes the margins are negligible, even most of the times if you compare the big names, but some times they are not, depends on the brand, etc.
You put a lot of work into a well engineered test! Although the following procedure could provide additional insight into the filtration properties/capabilities of the products under test, additional time/expense would be required. Specifically: 1) weigh each oil filter (new), 2) run the oil filters through the oil pump without contaminants, then record the weight of the following after a set period of time: the filters and the amount of oil drained from each, 3) repeat step 2 with a measured amount of contaminants. Thank you for your helpful contributions.
Great test. I run Mann filters for my whole life and have never had any issues with them. A lot of high mileage cars. But i am also very surprised by the quality of the Mahle filter. Interesting to see
Excellent video. It called my attention because I had problems using a Mann filter in my Mercedes-Benz. I was using either the MB OEM filter or the Knecht and things were just working fine. Then I used the Mann filter and after 2 weeks of the oil change, I noticed a rattle noise coming from the timing chain during the cold start that lasts a few seconds, and then it stopped. Checking the Mann filter construction (I had a spare one), it looked very bad because of the closing at both ends and the glue used, which made me think that it wasn't performing as it should and was not keeping the appropriate oil pressure during cold start, which would explain the rattle coming from the timing chain due to insufficient oil pressure. I changed the oil filter using the Knecht and the problem was gone immediately. No more rattle noise during cold starts.
@@craftedwithart Thanks for answering. The Mann filter that caused the issues is the model HU514X that was supposed to be compatible with the Knecht filter mode OX 183, but it is not. Like I mentioned before, once the Mann filter was replaced by the Knecht, the rattle noise during the cold start was over. As a mechanical engineer, it makes me wonder how such a bad quality filter can be even considered as a compatible part of Mercedes-Benz engines.
@@rogerriehl1612 I've noticed some rattle noise as well at cold start occasionally. And I have the MANN filter but ordered KNECHT couple days ago. The car is 560SEL
@@craftedwithart It's interesting to know that Mann filters fail in other MB engines. Apparently, they are unable to hold the oil pressure while the starter is running, thus the rattle. This can cause serious damage to the transmission chain. I just learned that the companies that manufacture oil filters to MB are Febi Bilstein and Hengst, this last is also responsible for AMG filters. So I ordered filters from both of them to compare and they have the same dimensions and appearance.
@@rogerriehl1612 Ye I'm always trying to find the perfect fit for my Benz. Much better to find the OE part without having to buy directly from Mercedes-Benz
Very thorough test. The secret is to use two oil filters for one oil change. I change my oil filter half way through my oil change period. Filters are cheap. Engine is expensive.
Excellent! This is some proper testing instead of just cutting filters open and speculating. Oil filter manufacturers have long benefited from people just trusting them on their claims and reputation, but now thanks to you we can know for sure how good they truly are. Would you also be able to compare K&N and Amsoil filters? These are two very interesting ones.
Thank you! I'm glad you like them and I hope my English is understandable 😅 in the future I'll provide subtitles in more languages so it's easier for everyone.
Thanks, nice test. However I don’t give much value for the filtration efficiency when it comes to looking at the caught dirt in the paper. You would need to do oil analysis to really know how efficiently they filter the dirt. There was a test of car oil filters in local magazine 2011 where they properly analyzed the results using proper equipment. Mann filter won that having one of the best filtration efficiency as well as second best dirt capacity. Knecht had worst filtration efficiency. When it comes to numbers it was 40% efficiency in filtrating 20 micron particles. Best filter had 50% and Knecht only bit over 20%. At 30 microns Mann filtered 90% and Knecht only 50%. However Knecht had best capacity for dirt but Mann was second. I don’t know how valid that 10 years old test is anymore, maybe they have changed paper or maybe not, but I personally do only buy Mann filters and change oil and filter every 10 000km. Filter manufacturers has to balance between filtration efficiency and capacity. If you were to have 10 micron 90% efficiency paper it would be clogged quite fast and the worst case scenario is clogged filter and opened bypass valve = no filtration at all.
The flow through the filter would be interesting. Like how much actually was pumped through the circuit. Because the Mann had less on the sample, but significantly higher active area.
Best filtering test on RUclips! The results are very interesting. Mann has thinner paper and larger surface area. So I was excepting to MANN's flow rate would be much more than knecht.
Onlly Mann Hummel! But,other German filters Are very good(Mahne,Knecht,Hengst . )

Thank you Sergiu! Please keep the english or in alternative hardcoded english subtitles. Watching you from Portugal! Great to see European products tested this way!
Fenomenal testul, ai răspuns la o intrebare la care probabil mulți dintre noi au căutat un raspuns. Măcar ne mai putem îndepărta de clasicul, " Domle'.... Manu' e Man" De apreciat efortul depus. Sa speram ca nu te oprești aici cu testele de filtre ulei. As fi f interesat sa vad în test Bosch, nipparts, starline. Spooor!!!
Very good job!!! Thanks very much!! I would appreciate also a comparative video for the fuel filters between the two brands such as the PU 936/1X and KX 228D for example.
Positive displacement pumps deliver the same flow no matter the restriction downstream. The power demand rises as does the pressure which is why a pd pump always has a pressure relief valve. Some more modern engines have variable displacement pd pumps.
In regards to being messy, it really depends on the orientation of the filter. I find pulling the cartridge filter from a Mercedes up and out much less messier than many spin-on filters, even when the opening on them is mounted towards the top.
Thank you, I'm sticking with Mahle/Knecht from now on. It appears that Mann has moved production to Mexico for the NA market and I have noticed a corresponding decrease in quality while pricing remains the same (or higher than Mahle in some cases).
It's a shame I can't find Knecht filters in Mexico, but I have used MANN for a very long time in VWs an Bimmers with great results. Thanks for the video.
@@SergiuGabor thanks for the advice, yes I have tried Mahle Filters before and they are really good, from my experience they are very similar to MANN and I always buy the one that is cheaper at the moment. VERY PROFESSIONAL VIDEO BY THE WAY.
Consider making future videos in English because your test are really professional, i would like to keep watching your videos and hear English commentary instead of reading translated text on video :) Subscribed and thumb up for this video.
foarte interesant.....ai putea face un astfel de test si pt filtrele de motorina.....se stie ca din cauza calitatii proaste a motorinei injectoarele au mult de suferit.... sa vedem ce alegem
They are company partnership, same engineer team but making different design. 1.MANN is longlife high pressure, syn oil 2.MAHLE is longlife filter low pressure, syn oil 3.Knecht is more filter but it's not longlife engine oil.
Faci o treaba excelenta, continut de calitate creat din tarisoara noastra draga. Ar fi internesant sa faci un test cu uleiuri de la acelasi producator si aceeasi vascozitate, dar vandut sub diferite nume de marketing. De ex. as vrea sa vad diferenta intre Ravenol 5W30 SMP/VMP/WIV III/VMP USVO. Toate respecta acelasi norme, dar USVO este ridicat in slavi si chiar sunt curios daca chiar e o diferenta fata de restul sortimentelor. Da-ne si o metoda prin care iti putem dona bani, sunt sigur ca sunt mai multi care ar dona si te-ar ajuta si pe tine sa cumperi uleiurile + alte materiale necesare pentru platforma de testare.
Abia am descoperit canalul tau si sper sa devii mult mai viral pe net, doarece meriti pentru munca depusa. Mult succes si la mai multe clipuri interesante!
You should weigh the paper only. The weight will tell you the amount of paper. The surface area and the thickness are useful too but the weight is more informative.
Bravo!Bravo!! Pot spune ca esti un supererou pentru buzunarele noastre :)) Cei drept nu mai am incredere in nici un producator de pise auto ,dar tu ai reusit sa imi dai un plus de speranta . Iti doresc mult succes in continuare si daca ai face un test si pe filtre de combustibil ma apuc si de revizie :)))
@Sergiu Gabor : Wouldn't the greater Value of "Folds" capture just as much as the other? The MANN was 156 folds and the Knecht was 120; so, wouldn't the Knecht appear to capture more - whereas the MANN has 36 additional folds to capture contaminants?
Really lot of work you made in this video. Very good analysis. But it look now like Mann is not good, but in reality those are good products. I wonder how other brands would perform, or even compare it also to the OEM from dealer :) One thing which is unknown is how much contamination has been passing though the filters. But this would be hard to measure. Will you make air filter comparison as well?
@@SergiuGabor cool. How about air on filters? Some of them are with carbon some of them without. And the are new filters from knecht lao series eg lao248 .
Hi one more comment from my side. You have been testing the material how fast oil can flow though it. This is telling us only the info about the material properties. Not saying that this is wrong, but I think missing test is how oil would flow over the whole filter construction, because at the end this is happening under the hood. Please consider this ;)
Buen video. Para verificar la eficiencia del filtardo podria usar el peso del material atrapado por el filtro, pesando antes y después con una balanza de precisión.
The testing machine is awesome. All the people are recommending Mann after OEM instead of other manufacturers. I would be curious how a Mahle or Purflux behaves in a test and compare with the already tested as well. From my perspective the high detail picture got me to conclusion.
Hi guys! Please keep in mind that I've made a mistake at the end of the video in the result table. My conversion from square cm to square inch is wrong.. by a lot. The correct value is 317.24 sq inch for Mann and 264.86 sq inch for Knecht. Sorry about that.
Interesant, nu stiam atatea despre filtre. Ce parere ai despre mahle vs hengst. Apropo in video apare cutia unui filtru mahle...

Positive displacement pumps deliver the same flow no matter the restriction downstream. The power demand rises as does the pressure which is why a pd pump always has a pressure relief valve. Some more modern engines have variable displacement pd pumps.

Really nice test. I'm in the same situation switching between Mann an Knecht. This test is relevant to choose knecht as the best oil filter. Thanks
Nice video and very detailed! You really know how to disect a problem and offer useful details!
So which is better? Also what about wix filters?
They are company partnership, same engineer team but making different design.
1.MANN is longlife high pressure, syn oil
2.MAHLE is longlife filter low pressure, syn oil
3.Knecht is more filter but it's not longlife engine oil.
Testing oil does not get any more exact than these tests.. Well done.
Faci o treaba excelenta, continut de calitate creat din tarisoara noastra draga. Ar fi internesant sa faci un test cu uleiuri de la acelasi producator si aceeasi vascozitate, dar vandut sub diferite nume de marketing. De ex. as vrea sa vad diferenta intre Ravenol 5W30 SMP/VMP/WIV III/VMP USVO. Toate respecta acelasi norme, dar USVO este ridicat in slavi si chiar sunt curios daca chiar e o diferenta fata de restul sortimentelor.
Da-ne si o metoda prin care iti putem dona bani, sunt sigur ca sunt mai multi care ar dona si te-ar ajuta si pe tine sa cumperi uleiurile + alte materiale necesare pentru platforma de testare.
Amazing content! I'm glad I found your channel
Abia am descoperit canalul tau si sper sa devii mult mai viral pe net, doarece meriti pentru munca depusa.
Mult succes si la mai multe clipuri interesante!
Great job and test, thank you!
Ai depus ceva munca pentru acest test. Bravo!
P. S. Mi-ar fi plăcut sa fie măcar mai un brand ca mahle, champion, purflux
Daniel Micle mahle este acelasi lucru cu knecht
Thanks Sergiu, very good explanation! , profy, I could say , keep going !
Am folosit doar mann, de acum voi folosi doar knecht, Multumesc!
Si eu care puneam nymsi mann crezand ca sunt cele mai bune ,aici in Italia sunt si cele mai scumpe .
Succes in continuare .
Great test and video. Awesome work. Thank you.
Interesting to see videos comparing several good brands.
Would be interesting to determine what those filters let through.
Great job!
You should weigh the paper only. The weight will tell you the amount of paper. The surface area and the thickness are useful too but the weight is more informative.
Bravo!Bravo!! Pot spune ca esti un supererou pentru buzunarele noastre :)) Cei drept nu mai am incredere in nici un producator de pise auto ,dar tu ai reusit sa imi dai un plus de speranta . Iti doresc mult succes in continuare si daca ai face un test si pe filtre de combustibil ma apuc si de revizie :)))
Mulțumesc frumos pentru apreciere! O sa fac un test si filtrelor de combustibil.
This was a great test i use Mann in 2016 vw tsi And my 2011 bmw but change the filter 3000 miles
I enjoyed this test a lot! Keep going.
Great clip and well presented keep up the good tests. Glad to have found this clip
English, good choice!! Thank you
Really nice videos. Keep up the good work! Respecte!!
@Sergiu Gabor : Wouldn't the greater Value of "Folds" capture just as much as the other? The MANN was 156 folds and the Knecht was 120; so, wouldn't the Knecht appear to capture more - whereas the MANN has 36 additional folds to capture contaminants?
Thank you! Simply brilliant video!
Really lot of work you made in this video. Very good analysis.
But it look now like Mann is not good, but in reality those are good products. I wonder how other brands would perform, or even compare it also to the OEM from dealer :)
One thing which is unknown is how much contamination has been passing though the filters. But this would be hard to measure.
Will you make air filter comparison as well?
Thanks! I'm planning to also test fuel filters and air filters.
@@SergiuGabor cool. How about air on filters? Some of them are with carbon some of them without. And the are new filters from knecht lao series eg lao248 .
Hi one more comment from my side. You have been testing the material how fast oil can flow though it. This is telling us only the info about the material properties. Not saying that this is wrong, but I think missing test is how oil would flow over the whole filter construction, because at the end this is happening under the hood. Please consider this ;)
Interesant. De apreciat efortul👍
Could you please test FORD OEM + VW OEM filters? For exp. GOLF 6 1.2 TSI? + 2.0TDCI ford
Good test. Your english is good enough. Have confidence!
Thanks for the encouragement!
Thanks for English.. now I understand what is being said about what.
Vw 2.5tdi oil filters where used.
Buen video. Para verificar la eficiencia del filtardo podria usar el peso del material atrapado por el filtro, pesando antes y después con una balanza de precisión.
Top 1 review!!! Bravo !
The testing machine is awesome.
All the people are recommending Mann after OEM instead of other manufacturers.
I would be curious how a Mahle or Purflux behaves in a test and compare with the already tested as well.
From my perspective the high detail picture got me to conclusion.
Mahle/Knecht, Mann Filter and Purflux are all OEMs. Basically they will comply to the requirements set by the engine manufacturers.
Knecht is double the price of the Mann, not how do these compare to the Bosch 501590247 or the K&N Oil Filter?
