Oil Filter Magnets

[lespaul]

Does anyone have any experience using the wrap around oil filter magnets? Are they worth the money?

[island911]

No.

(unless you get a shiny sticker to go with)

Search is your friend:
The next cool collar? Would you buy this for $89?

[Joeaksa]

Many cars have a magnetized drain plug, while a lot do not. Could not hurt but bet its kinda like the cool collar where part of it is in the mind of the owner of the car.

have you looked at yours after an oil change?

If only someone made a magnetic cool collar! Magnetic aluminum - now there's an idea!

Very strong magnets are available, probably stronger than the ones included in the products they sell for oil filters. Look for the word, "neodymium". Get 3-4 button-shaped magnets and stick them on the filter. You'll have plenty of change left over for a nice dinner.

If you have any old PC disk drives, you can take them apart and remove the magnet that energizes the head assembly. They are the right kind of magnets... Lou

What would be the point of a magnet on an oil filter? I can see the point of having a magnetic plug to catch something before it tore up the oil pump, or in the case of the tranny that has no filter. But why try to catch something that is gonna get caught anyway?

Also, there is a lot of non ferous metal in an engine.

Now I know what to do with all those worthless old HDDs I have tucked away. I could make a magnetic filter band and sell it on eBay. Now that's a plan!

Milt,
When/if oil pressure is too high, the bypass valve opens to allow unfiltered oil through. Last I looked, the bypass valve is in the filter can.

True, most bearing material is non-ferrous. However, ground metal from sprockets, gears, shafts and chains (heaven forbid) does circulate.

I'll await some pics of the internals of filters with and w/o the magnets -- should be interesting...

[cnavarro]

I would imagine they would do the most good at time of break in, no?

[randywebb]

sure - people can disclose that in their pics

BTW, I found that a lot of silicon accumulated when I let my '75 (carbed) sit a lot.

I have magnetic oil drain plugs on the Aston and the Porsche, and they always seem to have some schmutz on them But your all right, aluminum block, pistons,etc. not a lot of ferrous materials.

[911pcars]

"not a lot of ferrous materials."

Not that I think a magnetic oil filter will save an engine from certain death, but remember, most of the main engine components are made of a ferrous material, otherwise the engine would weigh about 50 lbs. less. They include:

Crank, rods, wrist pins. piston rings, rocker arm assembly, intake/exhaust valves, valve springs and retainers, camshafts, all chain sprockets, timing chains, intermediate shaft, oil pump gears. Lots of things to wear out when things don't go just right.

Aston?

If you grow tired of de-coking the heads, I'll take it off your hands...

Look for: Magnetised oil traps
