oil filter pressure bypass valve comparison

[@AikidoTubeSock]

This was the best, most concise explanation of how this valve works. You didn't waste my time with extraneous explanations of how the oil system on my car works like many others.

Very good you got the correct flow through the filter. Other videos claim the oil goes into the center and comes out the outer ring of holes.

[@sixtyfiveford]

Thanks.

Very interesting!!! Never pulled a filter apart before to see how they worked (or didn't). Thanks for sharing.

[@justiceofthesun7303]

Great video man, very helpful. I am currently having issues with my filter. This about sums it up for me. Filter wasn't filling up and i wondered if my engine was getting oil feed. Had a pressure gauge on a sandwich plate and had good pressure. Relief or bypass make absolute sense. Thank you sir!

[@sixtyfiveford]

Glad it helped!

[@doddgarger6806]

Good explanation thank you, I thought I knew everything already! 😆 Ive always thought to use the largest filter possible to avoid bypass as much as possible with the larger media area. I run a motorcraft fl1a on my jeep 4.0, seems well made with metal end caps..

[@sixtyfiveford]

I use the fl1a on nearly everything.

[@SlikLizrd]

The main feature of a Motorcraft Oil Filter is the Inlet-End By-Pass Valve. If the Fram Ultra had the Motorcraft By-Pass Valve, it would be the best oil filter on the market.

[@mikef-gi2dg]

I may just be realizing it, but this oil filter things has really blown up to something kinda big. This filter video has explained things in a way no other has. Makes me want to cut open every oil filter I have ever had....impossible. I like the by pass on top, at least heavy grin down at the bottom wont get drawn up into the engine.

[@sixtyfiveford]

The messiest, or maybe the busiest. Kidding. Thanks for watching.

[@sixtyfiveford]

Its a FL-820s vs a FL-400s. The internals are identical in function the filter media is just wider in the 820.

[@sixtyfiveford]

Thanks.. The E-Core is just a plastic tube in the middle of the filter media instead of a steel tube. Generally only on cheaper oil filters as it lowers the cost.

[@wtbm123]

Very well done and i agree with everything you covered.

[@fstarockaburns425]

very interesting explanation thanks!

[@Andrew__Smith]

YOU absolutely RIGHT!!!!

[@saltpepper1894]

Ive heard the rubber, maybe even silicone valve dries out sitting on store shelf for long time making the valve useless possibly causing oil starvation engine knock on 1st start up of the day... any thoughts on this?

[@sixtyfiveford]

Rubber may harden but silicone never will. However I've taken apart new filters from the 1970's that the rubber was still pliable. Even with the antidrainbacks the pump to the filter will be dry and there will always be a second-few seconds of dry start until it pulls then pushes oil into the filter to push through the rest of the system. However if you had an engine with a horizontal mounted filter and it ran dry I think it would add another second or two to refill it.

[@saltpepper1894]

@@sixtyfiveford I should have put "silicone" in quotes bc we dont know exactly what that industry considers silicone (ever had subway sub "meat"? lol). being 58 yo i can attest they made rubber & most everything else better back then lol. The horridzontal filter design could very well be a factor, wonder if theres a work around? Apparently this knocking on 1st start of the day is a real thing for Jeeps....Filter is the prob there, heres a vid on it kzbin.info/www/bejne/q3e7e2qBgsqtars

[@richardrichard5409]

No they don't harden and the seals are made from Viton😎

[@SlikLizrd]

What you heard is somebody's OPINION, because the FACT is that Silicone ADBVs WILL NOT deteriorate on the store shelf. PERIOD. RUBBER, on the other hand, CAN detiorate on the shelf, and it DOES deteriorate in hot engine oil. Rule of thumb: Look in the holes. If you don't see an Orange color, PUT IT DOWN !!

[@johnrommelt6560]

I'm glad you touched on this subject. What Filter has the BEST Bypass Relief Valve? Spring, stamped Are there others like Motorcraft design? I have a 2024 Nissan Frontier Wix XP, Napa Gold, Motorcraft, Other?

[@sixtyfiveford]

You can't go wrong with the Wix/Napa. Go with Motorcraft when you want an excellent filter for dirt cheap that is 99.8% as good as the Wix.

[@jasaircraft]

Which other brands have the pressure relief valve on top?

[@chevyiii]

Just noticed the Mobil 1 filter spec'ed for my car has the PRV in the far end with no secondary screen. The AC at half the price has the proper PRV design.

[@mustie1]

nice vid

[@joshd2861]

This was very interesting for someone who is (somewhat) mechanically inclined and interested but has hardly any knowledge in this area. I would love to know your take on how much difference the bypass value makes- 14 psi versus 23 psi. I've found a lot of discussion but no real answers. Subject comes up a lot when discussing after market subaru oil filters. Subaru's OEM filters use an unusually high value, i.e. 23.

[@sixtyfiveford]

Josh D Oil and oil filters is a very biased subject with no real answers. Just a lot of hot heads vomiting non factual opinions. Mechanical engineers spend a lot of time figuring things out to make them last a long time. But they are also paid to make stuff "work on a budget". I would trust good brand oil filters on any make of car. Like you know, the purpose of the bypass is to flow oil in cold conditions. The higher psi could cause slightly higher restriction and result in less oil flowing to vital parts, but their filter media might flow easier than media on a 14psi filter so it's a wash in what's better. Without having all the data, it's impossible to make a judgement.

[@joshd2861]

Thanks for the response!

[@bass305-HCCA]

Great video 👍

[@jimmywatt3918]

Like Motorcraft, NAPA Gold filters have upfront bypass valves and are generally made better, IMHO. Also a reasonable price for a mid tier filter.

[@AikidoTubeSock]

I use a Wix or a WixXP almost exclusively. I know that the Wix & Napa Gold are the same but does the WixXP also employ the direct to outlet type bypass relief valve as shown here?

At least now i finally understand somewwhat i kept hearing drainback valve but disnt truly understand it..now can u help with one question i just bought a royal purple filter 20820 on amazon u can see the spring coil on bottom of canisster why is that there what does it do for the filter.good video

[@sixtyfiveford]

djsmileyoflasvegas The royal purple is a good filter and has the top mounted pressure relief valve. The spring you see in photos applies pressure to the pressure relief valve. Essentially forcing the oil to go through the filter media, but if the resistance of the oil going through the media is to great it will overcome the spring pressure and flow directly through the relief valve.

[@DAS-Videos]

What I hate about oil filters is you can not see through them to see what is inside. I think at one point many years ago Fram was the best, and then at some point they manufactured them cheaper. The problem is you can't see inside to know what you are getting. It could be defective or empty inside for all I know.

[@TheFarmerfitz]

Maybe frame started out with the premium as shown and then later built the cheaper one... Best to just change the oil ever 5 to 6000 max kms. Regardless of what the book says......and make sure clean oil goes in and that the container and funnel are also clean...I Always check... A few minutes of paying attention can save big $$$....lol

[@SlikLizrd]

That's why you can come to U-Tube and see dozens of different brands and types of oil filters cut open and examined in varying degrees of detail, and often with conflicting "results". Among the "Testers", most of which are absolutley dedicated to a damned "Coil Spring", (it's actually inferior to the Stamped Spring) there are many who MEAN well, but are not qualified to make scientific measurements and report their findings in a manner that states FACTS, rather than use words like "nice" to describe a filter's ADBV. But hey, nobody's perfect -- some of the "Testers" have sloppy work habits, some have limited experience, and some have no idea what they're talking about. In any case, it's cheap entertainment.

[@bobby1970]

@@SlikLizrd I wonder if the Fram Ultra or Mobile 1 Extended Performance filter has a stamped spring? What brand and model is your favorite?

[@SlikLizrd]

@@bobby1970 Yes, the Fram Ultra AND the Mobil 1 both have a stamped metal spring, as do the most expensive oil filters (Amsoil, Royal Purple) available today. FRAM tells us WHY they use the Stamped Spring: The Coil Spring pushes on the CENTER of the filter cannister, which distorts the thin "dome" of the cannister. The Stamped Spring pushes against the EDGES of the cannister, and will not distort the cannister "dome" in any way. Some folks are so confused that they believe that those Springs are there as part of the PRESSURE RELIEF VALVE, when the job of that spring is just TO HOLD THE PARTS IN PLACE. The famous 95 MERC runs Pennzoil Ultra Platinum, 5-W-20; Bosch Premium Oil Filter # 3410; and a FILTERMAG #SS365PR Magnet Kit. Oil & Filter changes at 5,000 miles.

[@bobby1970]

@@SlikLizrd Thanks, I really appreciate the info. I would like to ask you another question if I could? Do you know of any good oil filters that have the pressure relief valve at the top of the filter (the opposite end of the filter that the base/cover plate is located)? My understanding that the pressure relief valve is the same as the bypass valve?

[@johnmoore1495]

You could also argue the mesh relieve valve is better. Because in the one where it enters and leaves immediately, it doesn’t stop anything big like that chunk you pulled out of the Fram, but the mesh would stop that.

[@hoghogwild]

Regarding the 2 Fram products, if the videomaker would have compared the 2 Fram filter medias, he would have discovered that there indeed is a difference between the 2. The higher end Fram has a different number of pleats that the low end Fram extraguard.

[@sixtyfiveford]

+hoghogwild The video has nothing to do with pleats.

[@hoghogwild]

A comparison was made between the 2 Fram filters in this statement, "same ah paper end capped filter er paper end capped ya filter media", when in fact the 2 filter medias are different.

[@SlikLizrd]

The type of material used in the filtering media has nothing to do with the number of pleats in an oil filter. HOWEVER, some filter manufacturers removed a WIRE SCREEN BACKING from their filter media to make room for MORE PLEATS.

[@hoghogwild]

​@@SlikLizrd a) Yes, I agree. b) The move away from "wire screen backing" is a mistake IMO. I've had the media blow out before. I wasn't impressed. I always cut open my filters now and I don't buy entry level super economy filters.

[@SlikLizrd]

@@hoghogwild Yes, I know -- A lot of people mistakenly believe that the wire screen was NECESSARY, and that the wire screen could not be improved upon. Fact is, they were wrong, but it's quite difficult to find anyone to ADMIT to their error. Unfortunately, many of the "Filter Tester" persons who provide the videos are not interested in LEARNING anything -- but are quite gung-ho on insisting that the wire-screen backing is/was the best available method for supporting the filter media.

Fram is fine, I wouldn't use the lowest end filter if you're one of the guys who does 10k+ miles synthetic oil changes, but if you're changing your oil every 5k miles it'll work fine. Almost every post I've seen about how they're terrible is not posted from engineers or good mechanics.

[@SlikLizrd]

The FRAM (Cheap-o model) is only suitable for 3,000-mile oil change intervals. The FRAM Ultra is good for up to 10,000-mile oil change intervals. As a retired engineer and a damned good mechanic, I can say without hesitation that NO oil filter should be run for more than 10,000 miles. The juice ain't worth the squeeze.

[@bobby1970]

@@SlikLizrd I change my oil every 3,000 miles regardless of oil type or filter type.

@@bobby1970 Unfortunately, too many folks have ignored the dangers to our air and water quality, and continued to change their oil at the 3,000-mile point, even though the quality of lubricants and filters have improved dramatically in just the last five (5) years. Simply changing from a 3,000-mile oil change to a 5,000-mile change point, is a savings of 40% on your oil & filter costs, and a 40% reduction in damage to our severly-distressed environment. It's a no-brainer.

[@bestofthebest3821]

this video explains how once dirty and clogged the filter with bypass on the top let all the sludge pass into the engine...

[@SlikLizrd]

That's what a By-Pass Valve does -- when opened, it allows the oil to BY-PASS the filter media and go back into the engine un-filtered. The superior By-Pass Valve design is with the valve at the INLET END, as used on some models of Motorcraft, Wix, and NAPA oil filters. This design prevents particles from being washed off the surface of the filter and sent back to the engine un-filtered.

[@bobby1970]

@@sixtyfiveford That depends on the filter. Some are made of glass fibers, and some are synthetic material (not paper).

[@AikidoTubeSock]

On an item that only costs at most $20 you would be foolish to cheap out and buy a crappy oil filter especially since most people only use 2 a year on average. If you use a Wix or Napa Gold the price is even lower. My only complaint about Wix is that the WixXP version is the one that uses a fully synthetic filter media but has a micron rating of only 35. The Wix regular/Napa Gold has a better micron rating (21) but is not fully synthetic it has a filter media that is (at least partially) cellulose. I disagree with the claim that cardboard end caps do not pose a hazard to the engine; most of the time they do not but some have come apart and caused engine damage (please research this on your own). The higher end Fram oil filters do away with the cardboard and provide metal end caps and a fully synthetic filter media but I still would be reluctant to use them on general principle.
