I've been using a MagneFine filter in the return line of the power steering on my Intrepid since replacing the steering rack. The company now has a product for engine oil filtration that spins on between the engine and the filter.

Take a look at their marketing and then do your best to rationally tear it apart.

How much do those cost?


I think the magnets do work, but the most cost effective way is a powerful magnet on the oil filter case......

...Yep, what emsvitil said. No special magical mystery devices needed, just a good magnet on the oil filter and maybe one on the side wall of the oil pan.

Too many people who were born on third base actually believe they've hit a triple.

The West Kootenay redneck version is to take the large magnet out of the giant 14 bolt GM rear axle and drop it in your oil pan.


<shrug> It still wont get any non magnetic bearing or piston junk....thats what filters are for.....

I can get a whole new crank out of the slant pile for.....welll .....free. That makes your filter magnet a hard economic sell.

When I worked marine engineering they were far less concerned about metal in the oil than carbon ....or unburned fuel ....or water....They used centriguges to get rid of that....no magnets.

I think its kinda like sacrificial diodes for iron blocks....unecessary but not harmful.

Having been inside many automatic transmission pans I know magnets work there. I had some trouble with a leaking 3/8" MagneFine inline filter so the rep is sending me a new one and the oil filter product. He sent me before and after test data on the magnetic oil pre-filter and the small-size particle count reduction was impressive. I guess I'd have to pay for some oil analysis to see if it works for my engine. Of course the rep said having the oil in contact with the magnet was best, but I'm not sure that's true.

Sandy,

I agree on carbon and fuel in oil being a big problem. Thankfully with EFI fuel dillution and carbon buildup are greatly diminished in gasoline engines. Also, Honda and Fiat are the two I can recall that had centrifuges standard on some engines and used no spin on or cartridge filter.

The in-line filters can be had for about $20 at Napa, the oil filter magnetic cartridge is about $35.

I've heard hard drives have some very powerful magnets. I could try some of those on my oil filter and see how the Magnefilter compares. So I need a baseline oil analysis, one with magnets on the filter and one with the Magnefilter.

I voted Probably, I'd like to see more data. I don't think it could hurt anything, but I don't know how much it will really help.
