<VV> super magnets attached to the oil filter

Sun Apr 10 22:07:59 EDT 2011

Sure you can put magnets on the outside of your oil filter and transmission pan, but wouldn't it better just to use  a superior lubricant?  

>From a physics point of view, there should NEVER EVER EVER EVER be metal to metal contact in an engine or transmission.  Everyone knows the results if there is.  I am a big believer in Amsoils' 15w-40 Heavy Duty Diesel and Marine Oil. (Yes this diesel oil works just fine in a Corvair)  It has the highest amounts of ZDDP out there and its film strength is 12 times that of petroleum oil so dirt and other foreign matter never penetrates the oil. 

In this case a really good oil filter, say around the 5-15 micron range removes all matter that size and bigger that could potentially do any harm. 

   As for the trannys, think about it.  How often does anyone change their tranny fluid?  Every 100,000 miles?  Plus a transmission doesn't do the work of an engine.  Its obvious why there are magnets in the pans.

Someone on vv told me that attaching super magnets to the body of the   
oil filter would not have the intended effect of trapping and   
attaching to the side of the filter any metal debris  suspended in the   
oil.  It didn't make sense to me, but not having a background in   
physics or mechanics, I just figured that there was some other   
physical property at play because I knew for a fact that magnets   
attract though both magnetic (ferrous materials) as well as non- 
ferrous materials.  I also knew that there was a ratio between the   
power of the magnet and the thickness of the material though which it   
would be able to attract. 
So, the only variable that I had not experimented with was a   
suspension of metal filings in motor oil. I decided to use an object   
that closely resembles the material that an oil filter is made of and   
the approximate thickness; a soup can.  I then created some metal   
filings using a small metal rod and a file.  I poured new motor oil   
into the bottom 1/8 of the can.  I then added the metal filings and   
stirred them in order to dissipate them though the oil.  Of course,   
most of the heavier ones sank to the bottom, but some of course   
remained suspended.  I then placed a super magnet on the side of the   
can.  I re-stirred the mixture imitating what would happen when oil is   
circulating though a filter.  When I poured the oil out, there was a   
neat circle of metal filings attached to the side of the can in the   
shape of the magnet. 
In my opinion, magnets do attract and hold metal filings suspended in   
oil when attached to the outside of a ferrous material; i.e., an oil   
filter canister. That said, I would suggest that attaching five super   
magnets to the bottom (circular end) of the oil filter is an added   
layer of insurance against engine damage.

GM has placed circular magnets in the bottom of automatic transmissions for 
years. If you've ever removed the pan on a later auto tranny, you'll see all 
this furry slimey growth on the magnet.
