Amazing Filter Demonstration - Save Your Engine 

40 years ago, Frantz oil filter distributors used an identical demonstration.

Technical babble and loud music in the background, what a great combo

I have an FS2500 on my diesel pickup. I take oil feed with a T fitting from the port containing my oil pressure gauge and I return the oil through the oil pan's drain sump opening. My oil stays cleaner and runs cooler due to the metal casing of the bypass filter radiating excess heat. I have read that engine oil provides up to 40% of the engine cooling effect. I've debated plumbing a heat diffuser or two into the system as well. Coupling this filter with 100% synthetic engine oil allows me to replace both this and my standard engine oil filter yearly. I add a quart or so of engine oil every filter change and every other filter change I plan to send in for an oil analysis.

I run a Frantz Bypass oil filter on my R31 Skyline, have had it on there for about a year now, only changed the filter element ("Toilet roll") today, oil was still gold and still smooth. Only reason i changed the oil was i went to a thicker oil as we are coming into summer here. They are the best filtration you can get. All the people who doubt these have obviously never used one so they have no idea. There is also no loss in oil pressure.

I have used this system in my 3406E model Cat for 19 yrs. I had 1,000,000 miles and my co-drive blow the motor by getting it to hot. My mechanic said I could have used the old bearing off the mains and rods. there had being very little wear because I use the Filtation System. total miles with this system is over 2,000,000 miles.

Bypass filters like this have been around for many, many years. They do work and there are thousands of positive, admittedly anecdotal results. However, don't think that this filter will result in new looking oil. It won't make your oil look amber. It will, however improve it's appearance somewhat.

WOW this really works in the video.

I put one of these on my 2005 GMC 2500HD in 2008 and recently had to replace a valve cover gasket that was leaking. Everything under the valve cover looked brand new. No sludge or even dirty oil at all. I change my oil and filters at 6k miles using 5w40 delo 400 and 2qt of Lucas since I got the truck back in 2006

news flash,,"most" engine wear occurs at start-up,when there is no oil on the bearings

I have read many peoples complaints about bypass filters and i don't think any of you get it. The bypass filter is a secondary system and takes out the smallest particles. Because of that you only flow a small amount of oil through the filter and you run all of the oil through approx 5 times a hour. Thats how they work. So there is no need to tell people they don't know what they are doing just because they want to improve on the oil in the system. These are and have been on truck tractor diesels for at least the 75 yrs. yes your oil will still turn black because of the dye discolours the oil but it does remove the damaging particles. That is how you get a million miles from a diesel engine. But if you think delete is the only answer well it isn't. I don't think they have gone about these systems properly to reduce pollution but delete is not the answer.

check out the HUBB filter. It whips them both and is washable. It does cost but has a 100k mile warranty

I've used Baldwin filters for a while after doing a research found that fleetguard was Cummins Filtration bought a Lube kit for the fuel and the engine along with the bypass filter. Upon priming my new fleetguard Lube filter I saw something shiny fall down into the oil I took a magnet and retrieved it pulled out a half moon coarse hair sized sliver of metal that was left behind from the thread Machining process. That piece of metal would have went right through the bearing journals people beware the quality control from fleetguard filters is not good I have never seen this on another filter. I'm glad I was paying attention and saw it

They had luberfiner filters out many years ago that did the same thing . Even thinking back we had a luberfiner on our 1935 TD 35 international crawler tractor that had a rag type media that was just shredded rags that you put in loose and packed it then screwed the top on .

good stuff, thats what im going to do next, send it to the lab, see if theres any copper or anything in the oil from bearings

I highly recommend filtration on fuel, engine oil, and hydraulic systems as well. Keep in mind big pieces cause the failures...but it's the tiny pieces that make the small pieces, that make the slightly bigger pieces, that create the big pieces that cause failure. Take out the tiny stuff and the rest of them are never created.

and it clogs up 10x faster

this would be perfect atv/dirtbike racing

Amazing. Do they make one for automotive applications.

It is a great filter demonstration. But Amsoil has had a system like this from the late 1970's and they sell the lubricants to go with it. They are only By-Pass filters, not full flow filters, but they can significantly extend the life of the oil and the engine. I have used them but now there is no room in my engine bay to install one.

These are great for stopping engine wear I use something similar on my car, while a full flow oil filter filters down to at best 20 microns. These can filter down to 2 microns by attaching to the pressure port and only filtering a bit at a time. The bull s**** part is yes the oil will still go black. there is soot smaller them 2 micron but it can't cause any wear and the filter is good for 60000 clicks or so

Amazing

I bought this system for my 2005 dodge ram cummins, I can tell you right now, the oil does not come out that clean, was still black as can be, im sure it helps but this demonstration is total bull!!

I hope they make a tiny version for my 1 liter motorcycle

In industry we have oil filter setup's that starts at a 20 and end at a 3 or 5 micron. We set these up on new drums of oil and filter NEW DRUMS OF BULK OIL! Yes if your worried about the oil look at the bottom of your jug of oil and you will see fines in a new bottle of oil.

My grandpa used to run those back in the good days when it was chiffon toilet paper they used

it means from time to time, you need to acknowledge the low oil pressure alarm and clean your filter.

I originally thought the FS2500 was the Fleetguard filter, but now I see that the competition is using an ID system very similar to Fleetguard.... I'd like to know what filter they're using to compare their bypass filter to...that white spin on filter looks like a basic filter, but what is it's micron rating? Thanks.

Quite interesting using a fs2500 which is a fuel filter.. and you testing it with hydraulic oil

It doesn't affect oil pressure. The system is such that they are plumbed in parallel and the bypass filter inlet is restricted to only take a small volume of oil, but its enough to eventually clean out even old dirty oil, new oil wont even get a chance to get any soot in it with these filter inline. Most people that run these end up extending drain intervals and getting their oil tested however. If you're just doing regular drain intervals the gains may be debatable.

Bypass filtration is a proven science. The FS-2500 units are some of the best on the market. I've run these units on my equipment for 20 years with excellent results. This demonstration shows how the filters remove suspended solids not dissolved solids. It is not going to make your diesel oil look like it is fresh out of the bottle due to dissolved solids in the oil. However, a laboratory oil analysis will show you that the FS-2500 does exactly what it says it does.

There's no reduction in oil flow if you use an oil filter adapter. The adapter lets the main filter and the bypass filter to be parallel to each other. Put another way, imagine going down a road that eventually splits off into two directions. One road is called "main filter" and the other is called "bypass". Most cars take the main filter road and a few take the bypass road. However, both roads rejoin a little further down the way and ALL the cars go into the "engine mountain tunnel" together.

GM did a study which was published by the Society of Automotive Engineers, reduce the size of particles filtered out from 40 microns to 5 microns and the engine lasts eight times as long. That's in gasoline engines, which are cleaner internally than diesels.

Could you tell me, at what temperature this oil on the video, that type of pump used ,and pressure operation?

Nothing beats Separ and Racor in these matters... And i do believe that Fleetguard would not be pleased to see this video :-)

Yes actually it is a 2.78 micron absolute (lab tested) element. And the reason it needs to be changed is because it HAS been tested to see how long it can go before it clogs. Take a look at the Southwest Institute Research tests on their website!

It seems like most commenters don't understand how this is plumbed into a practical application, if the bypass oil filter is blocked totally the lubrication system will operate normally.

Look at the discharge line going back into the reservoir, compare the both from filter to filter. Look how much stronger the flow is on the 2nd filter. This means a serious increase in pressure.

The term slows the flow of oil is misleading. These take a small amount of oil from the flow and clean it, then return it to the oil pan. As for clogging, you change these filters around 25,000 miles. Just change your regular filters at the proper interval.

Did you refill fluid with same amount of soot from the start. Maybe first filter goes into bypass from overload. So possible second filter might bypass too. Definitely second filter will get the smaller particles. Nice. Need one for my car.

how about centrifugal filters

get rid of your EGR....I did, and my oil is clear 'tan'' 6 months after changing oil and filter (08' cummins) using a quality Wix or Donaldson oil filter. And just change my oil every 3-5 thousand miles. Its no big deal, I do a whole day of maintenance. its fun!

I run by-pass conditioning coolant filters on all my vehicles and they work great. Would be nice to have by-pass high efficiency oil filters as well . Guess it would be quite a hassle to plumb on gas powered cars and trucks.

With that much contaminants captured, how often do you have to change this filter, every week?

my volvo 770 2003 with a ved 12 engine i only used fleetguard filters at the petro lube,i got 1,250,000 miles on it when i sold it and the only major problem was inj #5 went out mpg were 6.7 . it was equipped with 3 oil filters but only used fleetguard never donaldsons or red filters.

is this in addition to or instead of the original oil filter? only for diesel or will this work on gas engines too?

Anybody else notice how well that fancy filter aerates the oil? I wonder if any engine survives longer than 1 oil change.

Notice the change in flow rate when the "2500" is switched in-line. Am I wrong?

I have ran my frantz filtered oil for 44000 miles ..ha it tested and the lab said I could just keep going with it if I ha wanted to

I am shure wix and other accept fram are still good too the fs brand fleetservace or filter tech brand may not make car filters for us to use

how many litres of used oil can it clean per hour ?

Cummins owns Fleetguard so it is obvious why they would recommend Fleetguard filters. Cummins, like all engine companies make an enormous amount of money on parts. It is not in their best interest to offer filters that stop wear (If I made billions of dollars per year on parts wearing out I wouldn't either).The FS-2500 will dramatically extend your oil drain intervals AND completely stop the wear in your engine.This is a win for you and a win for us not so much for the engine & oil companies.

The smaller the partials the filter can catch the more often you will need to change the filter.

I think the 4 to 7 micron particles wear engines so much more is because there are inherently so many MORE of them, so this filter could have merit as a supplemental, not mainline device.

.... the most damaging particles are as big as the filter misses.... Most filters don't do well below 10 or 20 microns... so obviously the most damaging particles are going to be like 2 microns to 7. But what I want to know is... how many ppl have tried this secondary filter idea? It seems like an awesome concept! ... so long as it doesn't reduce oil pressure - which is why most oil filters have a bypass valve and operate at 10-20psi.... not 80psi.

Would this even be worth it for a diesel engine? They dirty up real fast and still go millions of miles, I think the key is fuel lubrication

@crazydiesellover Also, I just read this on the FS-2500 site: "The FS-2500 meters the flow of oil within the matrix of the element itself. The average flow rate throughout the life of the element (10,000 miles for Class 8 trucks) is 1.5 gallons per minute. This is very slow relative to what your oil pump is displacing, but fast enough to keep up with contaminant creation/ingestion." Now, they even say that the rate is slower than your pump works...so why is this not a red flag to them?

if it slows the flow of oil... can that really be a good thing? Moroso says... "After many years of designing and testing racing oil systems and related components, we’ve determined what’s most important to oil filtration. Many filter manufacturers stress the importance of filtering the smallest particles out of your engine’s oil, with references to "micron ratings" of 10 or less for a filter’s efficiency. With the help of research performed by filtration technology experts, Moroso engineers have determined that particles smaller than 20 microns in diameter are not large enough to produce engine wear. Furthermore, we’ve found that filters with extremely low micron ratings create an excessive pressure drop across the filter. They can be so restrictive that the filter by-pass valve can open. With the by-pass valve open, unknown to you-NO FILTRATION will occur! To maximize filter performance, Moroso Racing Oil Filters have a rating of 27 microns, which produces a maximum initial restriction of only 2.5 psi when tested to SAE j806! The result is less pressure drop, more flow, less oil by-pass and maximum filtration performance important in severe racing conditions." I'm gonna go, with Mor-O-So! (Ha!) ~ John B. ~ 1985 Corvette L98 (Un-Modified, 230 HP) ~ Moroso #22460 $16.95 at Amazon.

Is there something like this, but for gasoline cars? Like sedans, coupes, etc.

If you drive a car, this is not for you. Go to Jiffy lube pay $29.95 see you in 6 months. These systems are for REAL toys. Semi's, Graders, Heavy equipment. Every truck that you pass has 10 gallons of oil, that's close to $300 a month in oil changes for some trucks. These cost around $1000 and can pay for themselves in a short time on large equipment.

Deceptive I put one of these systems on a V8 and after 2k miles the oil didn't appear any cleaner/clearer then i used a clear plastic bottle and ran the motor to see whats coming out of the bypass filer line....dark oil it may filter to smaller particulates but it defiantly does not "clean/Clear up" oil

But how much does it cost compared to other filters and how much it last ?

the best thing to do is use a good oil filter and change oil regularly, i have always changed oil and filter every 5k road miles, and notice i said road miles as on asphalt roads.

Is your FS-2500 add on filter for common automobile gasoline engines?

if it slows flow, why is it blasting away when switching filters?

Big question for these filters. How much does the pressure drop across the filter increase by as it gets filled with particles and how much is the flow rate reduced. They never show pressure gauges or flow rates on these tests. To much of a pressure loss and reduced flow rate can be worse than only filtering out larger particles.

What about things that can dissolve in oil?

Can u make one for a 2.0 liter gas engine for my Mazda

How much clean oil was already in the filter? Did any filtered oil even make it back into the displayed container before the video stopped?

It's a bypass system. Not a full flow system. The main oil filter pulls larger particles and keeps the flow high to maintain oil to the engine. Bypass filtration slows the flow so much the engine would run dry. So, add bypass and give it a chance to work. It's not as magical as the vid shows. The video is not a running engine, hot and constantly adding crap to the oil. It will take 5-10000 miles and at least an oil change or two to clean like it shows. Put this on a new engine and you'll wonder if you ever have to change the oil. P.s. yes you still need to change oil but, not as often. Do oil samples and use a good oil lab. They will tell you to change it when it needs it.

where can i get this for my car

I want to buy that whole demonstration rig to filter used oil for a generator, how much for that thing?

Why is the oil so pressurized in the second test?YOU CAN CLEARLY SEE THE DIFFERENCE.

do they make one for a honda ZC ?motor?

Must be spec to car system, car system must be able to have same flow or better or you will starve system too. Need back pressure flow chart. And same specs for car or truck you want to use with

This is a bypass filter man. You will still have the regular oil filted on your engine filtering the oil. This one will filter oil as well, just in smaller amount. It will hardly effect psi.

Ok. Hey, I think ANY "add-on" oil filter is going to be BETTER than a standard filter. Especially for a Diesel engine.

How does it compete against Amsoil 2micron bypass filter?

I could recreate this test using a clogged canister filter and a brand new paper element filter.

you float the bearings at 30psi

You probably have to change this thing every time you drive to the corner store and back.

if the information in this video is true then why do cummins recommend fleetguard filters (which is the white filter in the video) for there engines and fit them as standard to new and rebuilt engines?

How do I buy this filter?

wow its so efficient I think we can use it to harness fresh water from the sea for drinking!! how much is that thing?

I run used oil through 2micron filters all the time, it doesn't change color like that

@crazydiesellover Just like an air filter that traps more dust, it would have to restrict air flow due to all of the excess trapped. Many filters get away with this by adding more filtering media so that the surface area is increased and oil/air pressure is un restricted.

You guys. Read what Dan P. wrote, or go to the Amzoil website, or Bobtheoilguy , and do some research for crying out loud. I guarantee when you do you will regret posting these ignorant statements. Sure sign of "wet behind the ears" behavior. And to Azourecosee, Diesel engines get dirty a hell of a lot faster than internal combustion engines, and use diesel oil which has much higher TBN specification which means several times the detergent as non diesel oil. Dirty oil in any vehical means that the oil is doing its job. If oil is staying clean in your motor chances are the oil isn't cleaning it properly. That is what one of oils most important duty is to clean the engine by suspending the soot in your engine rather than allowing to collect around in places like bearings and races, or just falling to the bottom of the pan. Then upon change intervals you get rid of it. The idea of a bypass filter gets better the dirtier your oil will get, and that is why installing it on your over the road tractor is a must to make money by keeping your truck out of the shop over the life of it. I guarantee using one will save you several 10s of thousands of dollars. All of the owner operators use em. The ones who don't struggle and usually don't stay in thier own rig and wind up working for someone. And for those of you that think it is easier to just change oil at frequent intervals is the way to go are not considering that tractors take 12 or greater quarts to change and that gets expensive. This is for professionals. All the manufacturers are putting them on as standard equipment now days. You have to add one to your vehicle if you want to go for a million miles with very little engine maintenance no matter what vehicle your driving. That is the issue in a nut. This is a good subject to start learning how to think in a logical manner. There is hope for the ones who actually take time out to view the video. I mean the first step to becoming successful is being curious about the right things.

why is the pressure different in the 2 filters? should make the oil filter see thru so we make sure its a new filter and not some used old dirty clogged up filter that's why the pressure is so low on that filter.

I need this machine

also,nothing magic happens at the 10k mile mark.Filters lose their flow capabilities almost right away because the previous filter was already saturated and oil was routed through the pop-off.Put on new filter and immediately those particles are captured, the pressure rises and the popoff goes into bypass again.There is only ONE way to avoid this and that is to run a fine filter and change it every couple thousand miles or less, and that isn't really an acceptable solution for most people

In my experience with regular oil filters the transmission will die long before the motor.

anyone else notice how much greater the pressure was when the 2nd filter was turned on? Was that because of restriction? Like a thumb over a garden hose? hmmm

wouldn't that just restrict oil flow and oil pressure with is designed to keep bearings working correctly, correct me if i'm wrong.

Your filter might be better for my engine but since cummings makes the fleetguard filters I have to use them to keep my warranty unless of course you folks will guarantee if your filter fails you pay for my engine repair correct.

Now, wouldn't something that filter that well dramatically lower oil pressure due to lower oil flo? You guys know what I mean?

How the filtration process its done,if you just submerge your filter in a jar,HOW??? JUST THINK AT WHAT I'M TELLING YOU.

Over a million miles? That'd be crazy and awesome if it does happen! What kind of oil do you use, synthetic? What brand, if so? What kind of "by pass oil system are we talking about here?"

but again if this information is correct then cummins fit filters to new and reconditioned engines that do not provide adequate filtration. Then they give those engines a warranty in my case I get a 3 year parts and labour warranty on rebuilt engines so they are willing to fit those filters knowing that they will cause the engine to fail so they have to pay for a rebuild or new parts. that doesn't make sense does it.

What is the price this filter?

So this "bypass filter" is going to filter out the: "zincs, anti foaming, acid reducers, corrosion inhibitors" etc.That Oil manufacturers have intentionally added to my engine Oil. It stays "clean looking." It can halt the complex chemical processes of wear simply by removing the carbon coloration in the Oil? Impossible. It negates thermal breakdown too? Effing amazing!

My question is: how can the oil flow be the same with such a high efficiency filter, and won't it raise the oil pressure by restricting oil flow ? Surely less oil molecules can pass thru in the same amount of time in a filter with "smaller holes" ?
