DIY Magnetic Oil Filtering

As mentioned, the OEM filter has a larger pore diameter than that, although you can get aftermarket units in the OEM cartridge style, or spin on's, with pore diameters in the 25-28 micron range.

I just can't see where taking out very small magic particles/bits would hurt anything. And might add to the life of the engine. But then again if it was THE answer to wear -you would find more magnets in cars and filters.

For example in an RV fridge- there is an anode rod the attracts corrosion. It's in all fridges. There could easily be a removable magnetic rod in the sump that you pull and wipe off at filter change time.

This might prove the magnet: find a car with a couple oil analysis to get a trend. Then add magnets- and see if there are changes or improvements.

BTW I put a magnet on the oil filter of Honda motorcycle back in the 80's so it's not a new discovery. And my dad installed a Frantz oil filter on all our cars in the 60's. it was my job to change the toilet paper cartridges- what a mess.

The problem of this thing as a commercial product is that they never wear out if you use the High temp magnets, so you only ever make 1 sale to a customer.

Its not new technology, just something so obviously good with no negatives that like you said, it ought to be on every engine and especially those with high engine repair costs.

You can't argue with the "Return on Investment" because if it extends the engine life to the next owner or saves you an engine overhaul or IMS Failure then its paid for itself 100 - 200 times.

I think we will all be surprised at what comes out of an engine at every oil change.

And World War II fighter planes had them as well...........

I just figured that the less abrasive in the engine the longer things will last and retain tighter clearances and better performance, particularly the IMS bearing and all the other bearing supported parts in the engine.

Its also a known fact that the stock filter bypasses some of the oil past the filter element so you are in fact getting ALL the different sized particles suspended in the oil going through all your bearings etc.

You can buy the LN spin on filter at over $150 to help minimize this problem or you can remove the problem. which is the metal suspended in the oil.

For under $50 I have a device that will reduce wear and last for the life of this car and many others.

I'd say the return on investment is very high considering how expensive our engines are and the high revs we are subjecting it to. The faster it turns the quicker it will wear.

I'm also a pilot/aircraft maintainer so I know the benefit is there. Its a simple cheap improvement that will not void any warranty and solves a problem instead of diminishing the impact.

As you can see from the pictures these do work quite well and can help every engine last longer.

You simply wipe the metal off the magnets at each oil change and you have done your preventive maintenance.

With the spin on its a bit more hassle because you'd have to reattach the magnets to the new filter with a couple zip ties.

I'll post pictures of the results at every oil change and I guess in a couple years we can draw conclusions at how effective this device is at removing metal particulates from the engine over time.

I suppose I could collect the metal and weigh it at each oil change to see if the rate of collection and engine wear is changing.
