Engineers Test the Best Oil Filters! FRAM | Mobil 1 | K&N | Walmart Brand

If you want to see other Oil Filters tested, let us know in the comments below!:yt:

Wix XP and Purolator filters are very popular. Would love to see them against these filters

One thing I would suggest, despite the difficulty of doing so, is using oil heated to normal operating temps for the long-duration tests. The oil/filter media relationship changes very much with temperature.

I've been using Mobile 1 high mileage synthetic and aFram ultra filter fo 15 years perfect so far, and on a 2004 Ram 1500 i have 400,000 miles still running good..Great Video!!!

This has been one the best actual testing of oil filters. Most other sites just cut them apart and give subjective opinions on their construction without any valid performance testing.

FINALLY a test were goes beyond just cut open and counting pleats...pressure differential and filtration capacity, that's what's really matters!

I’ve seen many other videos on oil filters from various channels. Most of them just cut it open and examine the internals. Your guys’ video is the first review I’ve seen with actual performance testing. Very well made and informative. Would love to see more!

🔥🔥🔥Why was WIX not involved in this test!?!?! 🔥🔥🔥

Subscribed, this was very thorough and well done. Hope you are compensated with many views and more subscribers and can’t wait to see more

This has huge potential. You should definitely do more brands. Penzoil, amsoil, oem filters, ect!

Along with the other great suggestions, I'd love to see some OEM filters stacked up vs. the aftermarket competition like AC Delco, Motorcraft ect..

The bypass opens between 2-5bar. When the engine is cold, no oil is filtered, everything goes in the bypass. Most engines have an oil pressure of 3 bar and above. Test the filters without the bypass valve and with different oil temperatures and see how much oil flows through the oil filters!

The sheer effort to make this video.... Thank you for making it from UK.

I get the 20k synthetic oil and pair it with the 20k rated filter.... and still change it every 3 to 5k miles 😅

This is what I wanted to see. Not just taking a filter apart to see how pretty it looks inside.

I used to use a bypass filter along with the normal full flow filter. It would filter constantly even and especially at higher engine rpm, and filter down to 5 micron. Since it is so restrictive, the full flow (normal) filter was there to provide filtering AND oil to vital engine components. However oil that was 2 years old was just as clean as it was at 500 miles. I changed the bypass once a year.

I'd probably go with the better oil flow over filtering, simply because it's easy to change the oil more often, which will reduce wear, whereas oil starvation will destroy your engine far more rapidly.

The YouTube algorithm worked here. I’ve been searching for real filter testing for over a year now. I really appreciate the scientific method and getting to filter performance vs look like other channels. This is very Project Farm style testing. Video quality is also great. I hope this goes viral for you guys. A few suggestions for future testing as I think this could be big for your channel. As others have suggested, I’d test other brands including Amsoil, Napa Gold and Platinum (or WIX equivalent), Royal Purple, Purolator One and Boss, AC Delco Ultragaurd Gold. Since you have built such a good rig and have access to a lab I’d suggest some extra tests. You could do a filter efficiency test to see, over a fixed period of time, how much aluminum of various particle sizes gets filtered out. Would be interested to test at 20, 30, 40, 60, 100 micron - effectively creating an efficiency per particle size. For the particle capacity test it would be interesting to take the filters to when the bypass lifts (or the media fails) and to know the pressure that happens at. Keep up the awesome work.

So my take away from this is the mobile one has better flow but it doesn't have better filtering capacity and for a non-performance vehicle the Fram Ultra would be acceptable in the essence of making sure the longevity of that engine stays very healthy for much longer Now with that being said I would ask you if you guys make sure that the bypass rate was the same for each one of these filters to make sure that the initial oil flow testing was accurate

Thank you! Great work/I appreciate the work! I must admit: The findings were right on line with what I have derived from many, many cars & the testing of every olive filter & then some! "And"... all on many different types of vehicles & driving modes! Stock, Modified, most all vehicles were performance models as well! Been driving for 65 yrs. J
