Amsoil Ea BP 100 Bypass Oil Filter Cut Open and Inspected

[@chrisfrane973]

I installed the bp120 kit on my 2009 kenworth. Isx485 dohc. 780000 miles. I cannot afford to lose this engine. $375 is a small price to pay for the added protection. High soot and moisture at this mileage is normal and was clogging the full flow filter in one day. Now there is no clogging in 10,000 miles and the engine runs better than ever with good oil pressures all day every day. I like this kit and installed it myself. All big trucks should come with this kit. Wtf!? I need to make it to 1,000,000 miles and prove it to my wife i bought a good truck. Period. No exceptions. Zero tolerance for failure. Must succeed. I ❤ amsoil! I change my oil every 10,000 Shell,mobil or chevron 15w40 $4.00 a quart + the full flow filter $50 no big deal. i dont care what anyone else says,thinks, or has done.

[@marvinscholten8643]

I know of a guy who went over 1,400,000 miles without an oil change. And he did not use a bypass filter or Ams Oil. I don't know if you have heard of Conklin Convoy but I would put it up against Ams Oil any day. If you want more info let me know 1(712) 441 - 3682

In the 1980's I ran 25,000 miles on one oil change in a Toyota gasser (20R) changing the filter at the half life and doing oil analysis, without bypass filtration. Amsoil is great stuff.

[@chrisadampetro5990]

Knowledge and the use of it is wisdom, . I own a 1984 w900 Kenworth, the shop manual for the cat 3406 b model 400 hp DITA engine calls for If my memory serves, 5w30, or is it 10w30. I installed a dual bypass amsoil filter system and series 3000 amsoil 5w30 and did a CAT full spectrum fluid analysis several times a year and NC Machines lab in Washington always showed no excessive wear on the test samples I sent to them. Final recommendation was always good oil health formula and no oil change necessary. I still replaced all three oil filters once a year and added top of oil. Now I ran a 3axle belly dump and also installed a pre air filter set up on both air cleaner canisters Sy-Clone and also a racor fuel oil water separator as a closed crank system. I had excess of 1,250,000 miles on it when I sold it. I also replaced the drivers and transmission fluids every year with synthetic oils. Usually in dirt work it’s not unusual to replace engine oil every 400 hours.

[@TheWwong]

I have been curious to see what the inside of that filter looked like, now I know. Thanks for posting

[@DieselWorld]

+ICU2 Your welcome, I was also curious.

[@TheWwong]

+dieselworld I myself, have been using a Frantz Bypass Filter for many many years. Then recently went to a Baldwin B164 for the convenience of a spin-on filter. But after reading many conflicting micron and beta ratings of the Baldwin I have gone back the the Frantz.

[@Best-Synthetic-Oilscom]

+ICU2 AMSOIL Bypass Filters (EaBP 90, 100, 110, and the Heavy Duty 120) are 98.7% efficient @ 2 microns, and remove 39% of soot smaller than 1 micron. Many filter companies will advertise either their filter efficiency % rating, or their filter micron rating, but not both. Without both numbers (efficiency and micron size), you can't compare filters, or know the expected performance of the filter.

[@clintroughton1423]

I was told as long as oil flowing it was good. The longer the filter is installed the tighter the filtration.

[@Best-Synthetic-Oilscom]

Clinton Roughton A quick test for spin-on bypass filters is to feel the outside of the filter after the engine has been running for at least 30 minutes. The filter should be very warm. If not, it is probably plugged, and not allowing any oil to flow thru it.

[@hjr9561]

I first had a 6 inch Amsoil by-pass filter installed on my Nissan in 1985. It was a canister when you took the top off and pulled out the filter, rather messy. But the filter medium was at least 2 inches thick. Amsoil has a filter demonstrator which has a tap on the outside bottom where you could drain off the water from the filter. It did remove water from the oil. It showed that it could remove every seem particle of carbon black that was added to the oil and you could compare it to a regular full-flow filter. With the tap half way, so oil flowed through both the by-pass could clean the full-flow. I had this on VHS video, but that was stolen in a burgulary many years ago. But I was surprised how thin the filter medium seems compared to the original by-pass filters. I did have an example, but that has been thrown out as it is all beyond my capabilities now. I then went to a dual guard, a by-pass and full flow on the same housing with an adaptor to the full flow mounting block. Now there is no room in modern engine bays. But the full Amsoil system on my car gave me a 14% improvement in fuel economy. And Amsoil withdrew from New Zaland in 2004.

[@ralphwood8818]

The old canister filter was a lot better than what they have now. They had Bobby Unser saying this oil change is forever. I think the reason the new filters seem good is they dont have much to do with these modern engines and modern oils. My old Ford diesel tractor has a lot better filter than Amsoil has but it has more work to do. It has a flat head Ford V8 canister filter converted to use Scott 1000 toilet paper. I have a package of 4 1/2 inch Scott 1000 toilet paper Most of the toilet paper filters take a smaller roll.

[@darrylsjodin7184]

According to Amsoil, the bypass filter is rated at 98.7% efficiency at 2 microns

[@johnheckscher7138]

There are different filter sizes

[@mikeallensonntag]

Honestly you won't see partials in bypass because your full flow already filters 20-25 micron. If you see visible metal shavings they will definitely be in full flow. Your naked eye won't see nothing in bypass at

[@DieselWorld]

Yes but the oil analysis sees all.

[@val_p7027]

Extend the oil? So high temps don’t still break down the oil properties ?

[@elithegreat6463]

Before you cut your next filter open, slap on a extremely strong Neodymium Magnet on the filter, An N52 from KJ Magnetics. And you'll really see all the metal partials trapped & held within the metal filter casing. I've had Magnets on all my cars and bike filters for Yrs.

[@papaal7014]

As a filter becomes filled with particles, it filters out even smaller particles, beyond specified. & more resistance to flow too.

[@dirkmcghee1604]

There is no 'pressure relief valve.' There is no bypass to the bypass, as that's redundant. If that thing fills up, it's NBD, it just stops filtering and full oil flow will automatically be diverted to the full-flow filter. When the full-flow filter fills up, it's bypass takes care of everything.

[@dirkmcghee1604]

That my friend was a piece of stamped steel, not a valve of any sort. It just holds the filter against the seal on the base plate at the other side.

[@2233redwing]

Hello Dieselworld, In this video you mentioned that this filter has a 2 micron rating and that this will not hurt the oil. I work at ExxonMobil and as part of my job I performed rigorous testing on lubricants. For your standard 15w40 diesel engine oil, it is not recommended to filter smaller than 5-7 micron. Otherwise it will remove the additive package from the oil. This degradation causes the oil not to perform as intended within the engine.

[@DieselWorld]

The lab analysis does not agree with you. 2 microns will NOT remove the additive package of Amsoil.

[@emrwtf]

Lmao. Hundred's of Thousands of oil analysis say otherwise.

[@ralphwood8818]

1 micron filters wont remove the additives in any oil Im aware of.. Some people spend money on oil analysis partly to get a list of the additives in the oil. The Australian Jackmaster Classic claims 1 micron if you use their elements. My 64 Rambler American had a spin on bypass filter. It was a 10 micron filter. The oil was always dirty and black soon after a oil and filter change. Installed a Frantz and the oil turned clear. About 1966 I found out about the Motor Guard. I think they still claim. Submicronic.All they make now is compressed air filters. I have two that are over 50 years old. They will remove solid additives such as graphite.

[@maxgarcia9512]

Great Video Sir. Thank you!! OK I'm going out on a limb here. Since I am researching this filtration system my question is this: Can you use a bypass oil filter in place of your normal oil filter to get the 2 micros of filtration? Why does it require two filters instead of replacing your stock filter? If the oil can't flow through the Amsoil filter fast enough, how is this benefiting the engine if there is only a small amount of oil going into the oil cap down the top of the engine. Help me understand how a small amount of filtered oil is a benefit. I think you said 10% of the oil? Don't get me wrong I want to add a filtration system if it really works, but I want to get the whole understanding of how this is actually working. Also does it only work with the Amsoil Oils? Again Thanks

[@DieselWorld]

Ok so here is the deal. You NEED a regular full flow filter at all times that will handle all the oil at any give engine speed. Because it flows well you have to give up some filtration. Lets say 30 microns. Now everything smaller than 30 microns does not get filtered and continues to circulate around with the oil. Put a bypass filter that filters to 2 microns and you divert about 10% of the oil to the bypass to get the 2 micron filtration. This little bit will still allow the engine to have plenty of oil. Now within about 5-10 minutes at highway speed ALL the oil has made its way through the bypass filter. If you only had a filter that filters to 2 microns it would clog up really fast AND would not flow enough volume to keep the engine lubricated since its restricted. By only allowing 10% of the oil to the bypass, all the oil eventually gets filter by the 2 micron filter.

I ran an old Gulf Coast Filter O-1 jr on a 1995 Toyota Avalon for a couple of years before relocating and having to sell the car. After I installed the GCF filter on it, gasoline mileage improved by at least 1.5 MPG. I believe this was due to the reduction of hydrocarbon deposits suspended in the oil, reducing friction on the engine.

[@ralphwood8818]

​@@bls1965 The Gulf Coast junior is as good as you can get. When Frantz went broke a Frantz dealer specializing in heavy duty diesels replaced the Famous Frantz 3 stacker with a big paper towel filter.

Hello, great video. How many miles or hours on the oil in the 5 years you said the oil was in the truck? I have a bypass system in my truck and just had oil analysis done. 7500 miles on oil and TBN is at 4.7. Blackstone said I can make it to 10k miles on this oil because the bypass system is "doing its job" I spent about $500 for the bypass kit and brackets. In about 3 or 4 oil changes the system will have paid for itself. I'm currently using Mobil 1 but might spring for amsoil if your 5 year mileage is 40k+ miles. Thanks for your time.

Wouldn't the dirt be on the INSIDE of the filter material? I thought the oil flows from the inside out?

[@bovellois]

No, it flows from the outside in.

The original Amsoil canister bypass filters were a lot better then the spin on filters at cleaning.

[@ralphwood8818]

As far as I know Fram went from using cotton to using almost useless pleated paper in their bypass filters. My 41 Dodge used a Fram bypass filter that used cotton. It was the same as a Luberfiner. You could still get cotton elements for them up into the 60s. I think they are all pleated paper now..

I have one in my 5.3L gas Chevy truck. I haven't changed it in 4 years. I don't think it's necessary yet. I do check the flow with every oil change and of course I am aware of the over pressure bypass. I do see a small drop in flow now and will probably fit a new one next change. My 2008 truck has 115K miles. It sounds and runs like new with the exception of a phantom check engine light. Those can be frustrating.

[@SlikLizrd]

That stamped steel spring IS NOT a Pressure Relief Valve. Its purpose is to hold the filter's internals in place. AMSOIL Products are severely over-priced, and practically un-available when compared to FRAM, BOSCH, & ACDELCO brands.

[@emrwtf]

Does FRAM, BOSCH & ACDELCO make a 2 micron filter for this application? If so please share the info. I'm sure most people would love to save 40 bucks on their bypass filter change.

[@SlikLizrd]

@@emrwtf NO. Only AMSOIL makes a 2-Micron-rated oil filter, and it's NOT a convenient spin-on. I don't want one of those 2-micron deals -- too much hassle, and no room under the hood. I get max protection from the 20-Micron-rated Bosch #3410 and a FILTERmAG # SS365PR Magnet Kit.

[@emrwtf]

@@SlikLizrd Umm. The amsoil 2 micron filters are spin on. and a 20micron filter isnt max protection. it's protection against particles 20 microns and above. I was hoping you had found 2 micron spin on filters(like amsoils) that were cheaper. I believe the original amsoil bypass were a cartridge type. Is that what you're referring to?

[@ralphwood8818]

They were a better filter than they have now. When I found out about them in the early 80s I was using Amsoil 10 40 with a Frantz oil cleaner. I also had a few Motor Guards. All of the cannister filters were a mess to change. Worked for a trucking company. We drivers had to change the Luberfiners. They used cotton. The newer ones used pulverized newspapers and wood chips. The big Gulf Coast filters use 2 rolls of Bounty big roll paper towels. Amsoil had Bobby Unser saying this oil change is forever when they came out with the cartridge filter. I have a Australian Jackmaster Classic on the Pontiac. They claim 1 micron. If you use their elements. Motor Guard has always claimed submicronic. I believe the Frantz claimed submicronic..The Australian Jackmaster Classic uses a high quality tightly wound roll of Australian toilet paper in a fabric cover. I would think the toilet paper filters would be similar. The Jackmaster Classic has the smallest orifice. It should have a slight advantage.The slower the flow the better the cleaning. There are filters claiming 1 micron that are more like 10 micron filters.

[@benstill571]

Old thread but here goes anyway. Burn the pleated part of the filter and collect the ash. Find yourself a AA spec and analyze the ash for metals. Then you will have a true understanding of what your filter is or is not doing. No guessing allowed. Best regards.

[@majorghn]

Doesn't this reduce the oil flow to the engine?

[@DieselWorld]

No not one bit. It only takes about 10% of the oil flow and diverts it to the bypass filter.

[@JuckFoeBurden]

Not even 10% the .032 orfice takes away maybe 1-2 psi

[@MrMe-rs3un]

I am running a 05 toyota tacoma 4.0. It does not reduce oil flow as this is a supplement filter to your stock full flow filter. I have installed a oil pressure gauge and have never seen a drop in pressure. Under freeway speeds this filter will clean all your oil in approx 15 min. I run Amsoil sig series 0-20. oil changes at 11,000-12,000 miles and send the oil in for third party analysis. I have less contamints then the average change sent to them with 5300 miles and they tell me I can keep running it.

[@ralphwood8818]

Bypass filters have been on engines since the 1920s. Most optional equipment. The orifice size average is 1/16 inch. I sometimes make them by putting a .025 wire welder tip in a brass fitting..In the 60s the Frantz oil cleaner didnt need an orifice if you used a two port Frantz sandwich adapter.. My flat head Ford V8 toilet paper conversion uses a Perma Cool universal sandwich adapter that I got from JEGS years ago. They were normally used for oil coolers.When you use a very small orifice you need to make sure the filter is heating up. The Jackmaster Classic is the best when you dont have much room under the hood.

[@Doubleantone]

Takes moisture out?

[@DieselWorld]

Yes it sure does.

[@ralphwood8818]

Dont depend on a pleated filter to remove water. The absorbing filters such as toilet paper can remove a few ounces. After the oil heats up it will remove the water fron the filter. Then the crankcase ventilation will remove the water from the oil. If you dont drive enough to heat up the oil you are in a heap of trouble.

[@nycalien]

No wire mesh? I thought Amsoil filters comes with wire mesh.

[@SlikLizrd]

That stupid wire mesh was replaced with more modern technology that became necessary with the extended 20,000-mile change intervals. The Uninformed have been flipping out about the wire mesh screen -- as if it was absolutely necessary in a top-quality filter. IT ISN'T !!

[@ralphwood8818]

The filter on the Pontiac Sunbird is a cartridge type. The last two filters were crushed by the oil pressure. I wonder if the wire backing would keep that from happening. The Wix on the Pontiac Torrant had 64.000 miles on it when I changed it. It was getting rotten but still looked good. It didnt have the screen backing. The Wix XP has the screen backing. On the pic 13:52 ture on the box. Normally I change the full flow filter every 2 years. Started seeing particles in the Jackmaster that should be in the full flow filter.

[@formerice]

I change oil on my Dodge hemis every 20,000 miles. 355,000 and 265,000 miles, use no oil still. Fram filter, haha.

[@yamaharidr450]

The bypass kit will allow you to help filter out more particles in the oil. But additive packages and friction modifiers are breaking down over time. Heat and pressure beats the crap out of oil. Its the additive packages that are protecting the engine. My opinion going 20000 miles on oil is idiotic.

[@brandon9715]

Depends on what test results of the oil say. If someone can run 20,000 miles on oil and the lab shows everything is still fine, there is no issue.

[@striveforselflessness3220]

No offense but you opinion doesn't trump science and test results. Like the other commenter said, you can send an oil sample out which will tell you what the status of that oil is. Then go from there.

[@ferrelx]

your absolutely right about the additives its called "shearing" to a point..base stock has a lot to do with it (class III is ultra refined dino oil) (class IV is 100% syn or PAO)...the "PAO"based oils will go farther thats why Mobil 1 Extended Performance is all puffed up with itself..(yes all mobil 1 products arnt 100% syn) theres only 3 100% syn oils that im aware of.."amsoil ss" "castro german made syntec" and the before mentioned "mobil"heres something that most folks dont know about with synthetics..the additives package is rejuvenated with the new top off oil that is added after a filter replacement..mind you this wont go on indefinitely..but it will get you that 20-25,000 mile mark.. also its been proven time and time again that friction is what makes an engine wear out..once you eliminate that (synthetics) then its dirt..hence the bypass filter..talk to fleet managers that run their diesel fleet on LP you wont believe how far they go on between oil changes because LP burns so cleanly..

[@ferrelx]

i actually posted a reply here a year ago asking when they changed from cellulose rings (it was like 13 pineapple rings stacked under spring tension) to this medium they have now..back then 20+ years ago they told us to run the bypass filter till it wouldn't get hot from the oil anymore :/

[@JodBronson]

+yamaharidr450 - I have to agree with you there... Another option would be drain a Quart out, and put a New Quart of Oil in every 5 Thousand Miles for " Viscosity "??? Here is the funny part.... Lab Test Cost around $26.00 (2017 Prices). Might as well take that Money and buy New Oil + New Filter. The plus part is... At least you know it's new and " Never " have to worry about the " Old " Oil. Also I like to note... 25,000+ Mile without changing Oil or even not " Just Examine " the old Oil, is beyond me. With all the Money spent on expensive Filters, Lab Tests, etc..... Just take that Money and spend on Cheap Oil + Cheap Filters and change your Oil every 3,000 5,000 Miles. At least you will know how your Engine is doing every time you change the Oil.
