Question on Oil Filter Magnets

Status
Not open for further replies.
Magnets don't do much to prevent " failure". What they do its catch particles your filter won't.


ISO counts tell that story conclusively a 1-3 point drop is a significant reduction in wear.


"Car engines go hundreds of K all the time" - that means absolutely nothing. Not a thing. Any engine can attain high miles.
Without a before and after leakdown test we/ you have no idea how tight and fresh that multi-hundred K engine is - it could be a gross polluter and leak like a sieve but still run.


Heres an interesting chart from Noria on potential bennies of magnetic filtration ... much more solid data/info than a Jesse Pinkman meme.

Regarding those minute particles that are caught by the magnets and held against the inside of the filter can, is that size particle normally caught by the filter element but was caught by the magnet PRIOR to going thru the element? It would be interesting to see how much metal is still in the oil AFTER it goes thru the filter. Would the metal caught by the magnet be caught by the filter?

I'm a firm believer that removing any metal material from the oil is beneficial.

Many thanks to all who contributed to this thread.
 
Many claim to have read about the subject, but few seem to have retained enough to be able to have a dialog about the relative areas they make a difference as reported by third parties whose input is relevant.


One of the most interesting to me is the assertion that they are so effective at removing smaller particles and controlling or slowing oxidation that a lower quality base oil can be used and still give a long life.

Another benefit of note and worth discussion falls under - "enhanced total capture efficiency" - this benefit rolls two issues into one and makes a statement about an often misunderstood topic of filter performance as they load up gets worse over time vs better.

We know about catching the smaller particles.
By stopping particle that would also be caught by the filter upstream of it - one improves the overall filter performance over time vs a stand-alone system.



Simple and total dismissals of the idea of a magnet(s) as a part of a solution show a lack of education on the subject and directly refute industry experts recommendations.

Not all is caught. A perfect example is draining your oil into an oil bucket and seeing what sits on the bottom of that bucket, after putting your hypothetical five quarts into a XL capacity detergent soap container for recycling.

I found the most metal on my magnetic oil pan bolt and on the bottom of that bucket, after using 5W20 where 5W30 should have been used in my GM model. The oil brand used was QS Synthetic and I ran it for 6K. The vehicle at the time had less than 70K on the 4.3 GM odometer and was well maintained.

The oil pan bolt was loaded with silvery metal and real fine shavings sat on the bottom of the bucket after emptying the oil. I ran that engine another 90K before donating it for free and no tax deductions, early last year. Needy family it went to.
 
I prefer the Gold oil drain Plugs

Wow - first I've heard of it.
I watched a YouTube Video on them..... impressive strength and power. Only dislike was the price ($18.99) and a need for a washer.
Thanks!
 
I run magnetic drain plugs in all my vehicles, and put them in during the first oil change. It's interesting to watch the level of captured ferrous material decrease as the engine gets more miles on it and fully broken in. Any kind of wear particles I can easily take out of the oil is a good thing.
 
The Dimples seem to be stronger. They can actually lift the weight of a hammer whereas the Golden can just lift it a bit but not the full weight. They also make Diff/Transfer case plugs. I think I'm going to get me a set for the Highlander AWD Diff/Transfer Case

I still have the I don't use magnets on oil filters with bypass valves to say again in "the magnet thing again."

I would have do unequivocally disagree with your claim that it "means absolutely nothing" that engines last hundreds of thousands of miles without magnets. My point is that even without magnets, engines last longer than cars. Engines last longer than most owner's desire to keep the car. I know this claim is based upon empirical data, but of this one I am totally confident. There are plenty of examples of million mile cars. Not one of them tell us that they did it by using an oil filter magnet or an oil plug magnet. And you can be sure that if they had, it would be well advertised.

So then, what purpose does an oil filter or oil plug magnet serve?

BTW, the "Potential" chart is another example of hypothetical benefits. It still offers nothing to show any benefit to engine life or reliability.

Why would anyone possibly believe you over him on this subject?

Some engines last longer than the cars they are in, claiming that as an absolute is folly that any small amount of searching will reveal.

Lots of truck engines wear out prematurely. Lots.

The chart uses the term "potential" because not all situation are equally applicable like magnetic particle removal in other wise unfiltered fluids can't have an effect on downstream filtration if there isnt a filter, but you can go ahead and try to pick apart Jims chart.

Manufacturers have been using magnetic drain plugs for decades.

Your opinion contains no viable 3rd party information - put it up vs. Jim Fitches expert opinion - you are hopelessly outgunned.

I always like the type of arguments justify that not using products that will keep oil cleaner is something that's OK because lots of cars make it to high mileage without them. And besides the body will rust away, or someone will T-bone and total the car, or you'll trade it in or sell it way before the engine blows up.

I might as well start smoking a pack a day of unfiltered cigarettes and only get 3 hours of sleep a night because I'll probably get murdered or in a fatal accident before I die of natural causes.

I know right?

I understand the question of how much benefit - thats a fair question- its also been answered 1-3 iso code drops.

but never did understand a position that cleaner oil with less particles isn't beneficial. Every bit of data shows cleaner oil produces less wear.

Whats utterly amusing is when people take a contrarian position to known trusted industry experts in this field like Fitch and Jim Allen when he talks about trans filters with magnets. Even when their research and data is right in front of them.

Maybe hypothetically, but smoking would be far more likely to shorten your lifespan than failing to use filter magnets is to shorten the life of a car.

How should I attach filter magnets on my aluminum-&-plastic cartridge housing?

I put 1/2 a million kilometers on my Santa Fe without magnets other than for one oil change interval to see what they would do for me. I guess if I had them on the whole length of time I might still be driving it as it would have prevented the snapped camshaft.
