Oil filters with magnets? November 25, 2011, 02:18:38 pm Yahoo Message Number: 126885I was reading about the properties and uses of the element Neodymium and learned that it's magnet properties are used in oil filters to trap metal fragments as they pass by. [Yes, I know, my life is quite boring to be reading about "rare" earth elements on Thanksgiving] This was news to me. I ran down one supplier of the oil filter called Filterdot. http://filterdot.com/filterdot4e_006.htm If it works, it would seem to be worthwhile the extra cost. Anyone know about oil and transmission filters with Neodymium magnets?
Re: Oil filters with magnets? Reply #1 – November 25, 2011, 11:35:50 pm Yahoo Message Number: 126896I've used magnets on my filters for years. Not sure exactly how much it benefits, but it can't hurt. I'm sure it does help to a degree though. Some car manufacturers use to install drain plugs with magnets in them. Maybe some still do? But I remember seeing lots of particles attached to the plug any time I changed the oil. Not sure you need to spend $25 for a magnet though. Any strong magnet should work just fine. If you happen to have an old disk drive laying around that you don't need, tear it apart and you will fine some incredibly strong magnets in there. But you can also find something good online that should work just fine.-Victor
Re: Oil filters with magnets? Reply #2 – November 26, 2011, 12:20:55 am Yahoo Message Number: 126897Here's my thoughts: I think anything that gets past your standard filter isn't going to harm your engine. I've used standard filters on my V10 for 170,000 miles, changing them and the oil every 5000-6000 miles, and the oil consumption is still about 1 qt/2000 miles, and it still gets the same mileage. But, I also agree it won't hurt, as long as you continue to follow the manual's oil and filter change schedule.Eric

I agree with Eric about the standard filter change being sufficient. But, I wonder why his V10 uses so much oil. I change the oil and filter on my 7 year old car twice a year and never need to add oil between changes; and I check it often. Perhaps the size of the engine accounts for this?
Re: Oil filters with magnets? Reply #4 – November 28, 2011, 05:06:43 pm Yahoo Message Number: 126943I consider 1 qt oil/2000 miles to be good for a new 6.8 liter engine, and excellent for one with 170,000 miles. It's as good as or better than any of the 3 full size pickups and one V8 Class B I've had. I can think two reasons a car might do better:1. The engine is much smaller (2.4 liters on my Camry vs 6.8 liters on the motorhome). 2. The car is usually traveling lightly loaded, compared to it's GVWR, while my motorhome is fully loaded (nearly at GVWR) and is pulling a 2500 pound trailer

Re: Oil filters with magnets? Reply #7 – November 29, 2011, 11:35:44 pm Yahoo Message Number: 126982"Anyone know about oil and transmission filters with Neodymium magnets?"Mike Many transmission and engine pans oil come factory equipped with magnets. If desired, find a large, old speaker, take it apart, retrieve the magnet and place it on the bottom of your engine or transmission oil pan. It will attract magnetic particles and hold them in place, inside the pan.. A good portion of free floating metal fragments, in an engine or transmission, are not magnetic, that's why there is a paper filter.Larry
Re: Oil filters with magnets? Reply #8 – November 30, 2011, 12:53:01 am Yahoo Message Number: 126987A few years ago I bought a FilterMag magnet that can be attached to the outside of a filter -- for a transmission in this case.. It's a VERY strong magnet that you would not want to get your finger pinched by! I have not tried cutting a filter in half after use to see what was caught but I believe others have just for fun...

The oil is changed every 3000 miles with the Ford-recommended synthetic blend Motorcraft 5W20. If my rig used a quart of oil every 2000 miles, it would be in the shop. ;-)As ever, YMMV.Joan

Our LD's oil usage is dependent changes according to the amount of towing. When towing, the engine spends more time in low gears, spinning at high RPMs. The faster the engine is spinning, the higher the rate of oil usage. Our LD will use a quart per 2000 miles, when towing, less if we are not towing. Other than the hassle of checking and maybe adding a quart, the cost is inconsequential compared to the $700-800 of gas burned in the same time period.Larry
Re: Oil filters with magnets? Reply #12 – November 30, 2011, 11:10:21 am Yahoo Message Number: 127000I forgot to mention that we also use Magnefine filters on our transmission for our Honda Odyssey (2001) which is known for eating transmissions regularly. They're not setup for engines though as I suspect the flow-rate is not high enough but are good for power steering or transmission applications.

[yeah, yeah, behind the wheel] Our V10 has 50m towing miles on it and has never used oil.Back in the 50's, hot rod lore was that a loose engine that used a little oil was a good thing.

I wouldn't be concerned at all about the cost of adding the occasional quart of oil if needed, but, in my situation, i.e., toadless, relatively light, and not a particularly "high revver" (me *and* the engine!) unless climbing, I would definitely question if something was amiss if the thing started "using" oil. At about $3.80 around here, the $$$ "gas suck" is indeed tough; time for a "fill the tank" garage sale! ;-)Joan
Re: Oil filters with magnets? Reply #15 – November 30, 2011, 07:16:47 pm Yahoo Message Number: 127019We have an 06 30'. When we first got it we did not tow and were not fulltiming. It used no oil between changes. We have now been fulltiming for awhile and tow a car and since we started that it uses oil as Larry indicated.Jim C
Re: Oil filters with magnets? Reply #16 – November 30, 2011, 07:17:50 pm Yahoo Message Number: 127020I agree. As long as it doesn't change, whatever amount it is using isn't an issue, but if it starts to steadily trend up in usage, or suddenly increases, that would be cause for concern. It's amazing to me how long cars and engines can last nowadays, compared to when I started buying them in the 60's. Then, getting to 100,000 miles without needing rings or a valve job made an owner giddy with delight! Now, it's really bad luck if that happens.Eric
Re: Oil filters with magnets? Reply #17 – December 01, 2011, 10:06:25 am Yahoo Message Number: 127036Eric's comment re how long engines last now, is indicative as to how things have changed. My 2010 Toyota FJ Cruiser's owners manual says the oil change interval is 5,000 miles. But after purchase, I soon got a letter from them advising that this should be corrected to 10,000 miles unless the vehicle is subjected to severe service. This is due to improvements in metallurgy, tighter tolerances, and the use of thinner multi-grade synthetic oil (0-20 W is required), Unlike my 70 year old technology aircraft engine that uses 50 W oil and is, relatively speaking, loose as a goose, the modern automotive engine is not very likely to 'make metal' . . . for the aircraft, the oil filter is cut open and the pleats pulled out to check for metal at every oil change. Magnets are sometimes used for 'chip detectors' that hopefully may give enough advanced notice of an impending engine stoppage to make a difference. Chip detectors are common on helicopter engines and gear boxes, not so much on small planes. With modern automotive engines, such catastrophic engine failures are rare. Unless one is not going to cut open their spin on oil filter to check every oil change, using e-bay rare earth magnets doesn't seem all that beneficial.bumper[Non-text portions of this message have been removed]
