The cleaner your motor oil, the better your engine will run and the longer it will last.
Magnetic technology does make a difference; reduces fuel and oil consumption and extends engine life.
I submit Magna-Guard Oil Filter Magnetic is the most significant improvement in engine preventitive maintenance since the invention of the oil filter. SAE Technical Papers 881825, 881827 & 95255 demonstrate the benifits of controlling particle contamination down to the 10-micron range as opposed to standard 20-30 micron filters: 3.7 - 5% increase in fuel economy, 8 - 14-times reduction in engine wear, doubles useful oil and oil filter service life. Independent Laboratory analysis have demonstrated that adding Magna-Guard Oil Filter Magnet to your oil filter controls particle contamination down to 0.5-microns. This science is posted on www.magna-guard.com.

Since this has become such a long post, I will repost what I stated earlier:
I do not have "first hand knowledge" of the benefits of using (or not using) Oil Filter Magnets. However, some of the people I know in the industry have opened some filters with magnets on them and found metal "dust" on the insides. It certainly cannot hurt anything ... AND for those operating on a "shoestring budget" ... if you have any old dead computer hard drives you can open them and remove very powerful magnets for free!
One of my customers has been using a product called "Bear Straps" for years. Its just a rubber strap filled with powerful magnets that straps to the oil filter. He has informed me that he cut them open and found a surprising amount of "very fine, dust-like" debris in them! I don't know the condition of his engines, etc., or why there would be a "suprising amount of "dust-like debris". It has been my opinion that any particles that are not trapped by the filter would be held in suspense in the oil and eliminated with the oil change.
That being said, it might be a good idea for someone on this site to TEST oil filter magnets and let us know the results.
HAS ANYONE DONE THIS ???

Dear Steve Roark,
We have conducted 5-years of R & D and documenting the benefits of adding magnetic technology to enhance the filtration of engine fluids, specifically motor oil. Much of this research is posted on www.magna-guard.com. I am a strong advocate of Amsoil and we have several Amsoil Distributors selling Magna-Guard with your products. I invite you to contact me and I will be pleased to share our research and documentation with you.
Just a quick technical renote: The lubricating oil film separating opposing surfaces in an engine is between 2 and 10-microns. Approximately 90% of the particle contamination that builds up in engine oil is in this size range. Because these micro-fine particles are in the same size range of the dynamic oil film separating moving engine parts, they generate 3.5-times more engine wear than larger particles. By making simultaneous contact with opposing surfaces these harmful particles focus the load onto a small area, degrading the surface and perpetuating a chain-reaction-of-wear. As oil filters are typically designed to only remove contaminates larger than 20 to 30-microns in size, they allow these smaller particles to pass through the filter and continue to build up in the oil system. As a result, motor oil is frequently changed before it is depleted to prevent premature engine wear and loss of performance due to friction caused by these harmful micro-fine particles.
Lube oil contamination accounts for 70-80% of all failures and wear problems. The wear process promoted by oil contamination leads to diminished fuel efficiency, shorter useful oil service life, increased engine down time, reduced component life, loss of engine performance, and an overall increase in operating costs.
I would also like to dispel one myth, a majority of non ferrous particles are also removed from the oil as a result of magnetic filtration. This occurs through amalgamation or the clumping together of non-ferrous particles with ferrous particles. Regardless of the oil's additive package, specifically the particle suspension formula/component, amalgamation does occur. Therefore as the ferrous particles are captured by the magnet, the non-ferrous particles attached to these particles are also removed from the oil system.

PS Dear Dr. D, I invite you to review our research and documentation. The goal is to extend service life, improve performance and reliability, and reduce consumption. A more efficient running engine also pollutes less.

micron equals .00001, main bearing clearance on a new engine equals .001 - .0015, with that in mind how does a .00030 dia particle (30 microns) fill up the space? one on each side is still only .00060 leaving .0004 - .0009 actual total clearance. I know for fact my numbers are right so what am I missing? what you posted as far as clearance and interferance is not possible.

I have been reading these post for awhile withholding comment, although this has not been mentioned in the last few post. There seems to be some misunderstanding about the direction the oil flows through a filter. There have been comments about the magnets doing nothing but attracting the fine particles that the filter has already stopped. This is compleatly false, the oil flows out of the engine through the center of the filter, passes through the filtering media to the outer canister then up into the engine. If you are catching fine particles by way of a magnet then you are catching particles that have passed through the filtering media.

I am not against the use of magnets in an oiling system however, I feel that synthetic lubricants, proper filtration (including a by-pass filter system) should be the first items on any performance wish list.

Having worked for the past 15 years in hydraulic, automotive and now magnetic filtration, I have to completely agree with the comments posted by Ron McElroy. Even his final paragraph regarding the removal of non-ferrous contamination by magnetism is correct. I have many documented instances of this effect in many differing industrial lubrication applications.
Whatever technology you prefer to decrease engine wear is a matter of personnal choice (and of course the size of your wallet!) but as an engineer, removing the most potentially damaging contamination in the simplest, cheapest and re-usable manner just makes sense. But beware. As someone else has said, "a magnet can't hurt" or can it?
A bare magnet in any fluid system, be it a bar, strap or sump plug, is susceptible to "wash-off". The magnetic field generated by the magnet diminishes the further you get from the magnet surface and this leads to the long chains of contamination or "fur" you have probably all seen. The contamination at the ends of the chains is hardly attracted at all and in peak flow conditions can be washed off. The point here is that this contamination now has its own induced, although small, magnetism and will adhere to the moving ferrous parts as the oil flows around the system - possibly causing more damage than if no magnet was installed.
I am currently working on a magnetic oil filtration device which will overcome this potential problem and the key here is to provide enough volume to store this contamination out of the fluid flow between service intervals or possibly for the life of the vehicle.
Feel free to contact me if this is of interest to you.

Not tryin to Dis anyone here, cause I do believe that the magnet concept is all good. However, most of the material that I have extracted from used oil from an aging engine has been non-ferrous metals. Engines are designed with the concept in mind, that all controllable wear will take place on the replaceable bearing surfaces, which were designed of brass, copper, Babbit, etc.. in foresight. Yes, the alloy rings do slide along the cast cyl. walls etc, and there is ferrous on ferrous wear taking place at other places inside the "mill" . I believe that oils should be of good quality and changed often. All things being equal, a magnet as an oil plug(like on farm tractors) will perhaps catch that loose washer before it causes collateral damage. Rather than worrying about the dust that a Quality filter would have filtered out. Hence, it is a filter after all, just let AMSOIL make 'em all, and they will do the job, as a filter should.

4XDAX brings up an interesting point in that the fine particles are pulled off after the oil has gone thru the filter and are collected against the outside wall of the filter. Then Paul brings in the idea that the magnetic field gets weaker as you move away from the magnet thus alowing clumped particles to be washed away presumably into the engine bearings. At this point it begs the question Do you get more wear because of the larger clumps or do they break down into their respective small particles. Food for thought anyway

Why not just install a by-pass filtration system like Amsoil
offers? It filters down to less than 1 micron.
Magnets are great for transmissions and engines that don't have
oil filters; but pretty much useless on pressure type lube
systems where an ultra fine filtration will do a much better job.

I think we all agree that engine oil is the lifeblood of your engine. Most of you also realize that the cleaner your motor oil is, the better your engine will run, and the longer it will last. Therefore the name of the game is optimizing oil filtration.
For instance, here are a few facts as documented by SAE (the Engineering Society for Advancing Mobility Land Sea and Air) Technical Papers #881827, #881825, & #952555:
The benefits of replacing standard oil filters with 10-micron filtration are:
8 to 14-times reduction in engine wear
Up to 2-times increase in useful oil service life
Up to 2-times increase in useful filter life
Up to 5% improvement in fuel economy
What does 8 to 14-times less wear mean?
A typical General Motors engine’s life equipped with a 40-micron filter is 150,000 miles.
Replace that 40-micron filter with a 10-micron filter and that same engine’s life is extended to 405,000 miles. (SAE Paper #881825, David R. Staley – GMC)
As many as 90% of all particulates in engine oil are in the same size range as the oil film that separates moving parts under load, 2 to 10-microns. These particles are responsible for 3 ½-times more wear than larger particles. Therefore controlling particles in this size range will yield the greatest benefits.
As Dr. D points out, a well-designed by-pass oil filter controls particle contamination down to the 1 to 2-micron range. Unfortunately by-pass filters typically filter only 1/10th. of the oil that flows through the full-flow filter at any one given time. Therefore, engine oil must circulate through the engine at least 10-times before it will come in contact with the by-pass filter. This allows ingested particulates that enter the oil film to promote a chain-reaction-of-wear.
The solution is to utilize a magnetic device on the full-flow filter. For instance our product, Magna-Guard Oil Filter Magnet, inserts into the filter’s outflow reservoir to optimize performance and benefits. It magnetically adheres to the filter’s metal core thus magnetizing the core. As oil passes through the core it comes in direct contact with this magnetic field.
Magna-Guard Oil Filter Magnets help control particle contamination down to the 0.5-micron range. This allows for the immediate capture of smaller particles by the full-flow filter that would otherwise circulate until they came in contact with the by-pass filter.
Capturing these smaller particles on the filter’s core or on the magnet helps prevent the filtering element from eventually clogging-up and forcing the filter into the by-pass mode.
Maintaining the filter’s porosity provides better lubrication to the engine throughout the service of the filter, and can double the useful service life of the full-flow filter as well as the by-pass filter.
Dirt simple isn’t it.
