Dream on.  

Yes, they do work plain and simple.  They are plain, and certainly simple.

Please keep using schmagnets, though.  There is not much of a downside, and it makes you happy.  It is good for motorcyclists to be happy.  

Best is to use a good hi-performance (MOTORCYCLE) oil like Klotz,Warning- its not cheap to buy but very cheap in the long run.

I always use high quality syn oil in my bikes and truck. Mobile 1 or Amzoil. Not only in the engine but the tranny and rear end as well. I Put a magnet in there same result fuzzy metal stuck on it!  They work!

For those that think a magnet is a joke, do a little experiment with your truck or car or bike etc. Buy magnetic plug run 3k miles or 5k  miles depending on the oil and conditions then change the oil and look at the plug....if it has anything on it well that is proof it works!  It will.

All engines wear new or old and the stuff that wears off the gears and cylinder and rings goes somewhere....if your smart it gets stuck on a magnet!

Aircraft use schmagnets for a real need.  In aircraft motors, there is a lot of analysis that happens at each oil change.  

You can go as far as sending the oil off to a lab that will give you a report on the exact proportion of what materials they find in the oil, which will then give you an idea of the internal state of the motor.

If you choose to not suffer the expense, then a schmagnet, combined with the cutting apart of the oil filter will give you a less advanced way to understand what might be happening inside.  

If over the last 30 oil changes, the schmagnet has had nothing other than a dusting of powder on it, that tells you something.  If at oil change 31, there is a marble-sized buildup of shiny little shards, that tells you something else altogether.  You'd best be tearing that engine down, and not hauling any humans with it.

So, everyone here, please use schmagnets.  They may serve as early warning devices.  Aside from that, though, they don't do squat.  As Boule'tard says, they add zero hours of service life.

Don't put words in my mouth.  I said the magnets matter nothing to an engine scheduled for rebuild at a certain, conservative number of hours anyway.  That is not the case with our motorcycles.

Your characterization of others' comments on this thread is similarly cheap and incorrect.

Aw, don't play dumb  Clearly, you applied the comment to a different case.   Anyway, apology accepted.

So, what do you make of manufacturers that use magnets in their original engines and transmissions?  Some are attached to the drain plug and meant to be cleaned at each oil change (Husqvarnas) and some are to be cleaned during a major service when the pan is off (Toyotas).  Neither are for inspection purposes, the manuals just say “clean them.”  

Huskys generate a ton of engine-trash and IMO need all the filtration they can get.  Toyotas, not so much.  I would guess the Savage falls somewhere between them in terms of junk sloughed off the engine parts, and general engine stress.  

Then we have the manufacturers not wanting to make maintenance a bigger deal than is necessary to make the engine last as long as the rest of the vehicle.  So the designers come up with various screens, paper filters, magnets and centrifugal devices that they think will provide adequate filtration while not making maintenance too much of a PITA.  The ones that incorporate magnets into their designs aren't exactly the copper health bracelet wearing, placebo-popping idiots you might imagine.  Magnets catch stuff that is bad for engines.

Adding a magnet to a finished design might well go beyond a “point of diminished returns” and the owner might never notice the difference in wear.  That is the point I think you are trying to make.  But you can't say the difference is zero, and you don't know how significant it is.  The magnets do indeed catch abrasive material that would otherwise be circulating around the engine.  So an owner that chooses to run a magnet is reducing the wear on the engine to some degree.  You can call that insignificant, but you can't call it nothing.

gyro an idea why dont you just remove the oil filters from your bike and cars...they are as worthless as magnets  stick your head in the sand like an ostrich and all will be right with the world.  

When presented actual facts from someone who has been doing something for 30 years and has proven to work. Then to have some pinhead dismiss it as dribble....well that pretty much proves you are  wanting to cause trouble or you are a moron.....this is the end of my comments to you!!!
