Thanks for the critique but I think your test is very flawed to the point you drew the wrong conclusion. You see when your motor oil drains back into the pan over night everything kind of settles to the lowest point (typically the plug). They stick to the magnet and stay there. The problem with your test is you just kept shaking it up. The goldplug works quite well and I have used it in all my motorcycles. Had this test been for aluminum engines then you do have a point but for the wrong reasons. Aluminum just isnt ferrous.
I see where you are coming from. Do motorcycles engines wear faster than regular car engines? These plugs would catch some metal shavings but I’v have no seen or heard in conversation about these plugs being truly helpful. Thank you for your input and comment.
@@DriversTherapycan you repeat it where you let it sit overnight with the magnet at the bottom and then see what it collects? It should be easy since you already made it and you get an extra video
First off the oil in an oil pan does not shake violently. It circulates in the oil pan. I have changed thousands of of cars oil. In cases where an plug mag was used I have seen plug mags completely covered in in metal particles. So yes in the real world they do work. If the filters did filter those particles out the plug mag would not have been covered in particles.
I saw you recently posted and you seem to have good knowledge, so I'll ask you. I've heard some people put a strong magnet (like neodymium) on the outside of a regular bolt to make it magnetic. Would this work just as well? I just changed my oil so I won't be able to remove my regular bolt for a while, but would like to have the benefit if a magnet.
@@davidm4566 Well the magnetic field will get weaker the further from the magnet it travels. If you add a strong magnet on the bolt head the field will follow the bolt and I would suspect that the end of the plug would be magnatised thought not as strong as thee magnet itself. Take a file and produce steel filings. Using the bolt preform a test with the mag on the head of the bolt and test to see if the end picks up the filings. You can put the filings on a piece of paper and move the bolt end under the paper and see if the mag field is strong enough to attract the filings sort of a test of the strength of the mag field. Good luck.
If you put magnets around your oil filter it'll pick up a lot of those shavings in your motor even the little drain plug it helps a little but if you put it on your filter it'll pick it up because all the oil flows through the oil filter.
What if you don't have an oil filter on your bike? Will it still work if you put a strong magnet on the outside of the bolt? I just changed my oil but would like to have the benefit of magnets.
I'm curious what would happen if we put a small neodymium magnet right on the outside of a regular bolt. It seems like it would work and I just changed my oil so it will be a while before I'll remove the bolt again to use a standard magnetic one, but I'm new to this stuff.
A engine with metal particles that big ....is a broken engine 🤷♂️. There's no need to do an experiment to see if a magnet can attract metal (that's obviously yes) The particles that the filter doesn't catch are very fine and came about due to normal engine wear after 1000s of miles/ months. And best way to get rid of these particles is to change the oil 🤷♂️... not to place a magnet on it. Most magnetic oil plugs from manufactory are magnetic, not to catch particles in oil to prevent engine damage, but instead there to catch large particles to let mechanic know there's damage in engine😎
Cool test, but in my opinion it has little relevance in the real world for several reasons. First of all, if there's chunks of metal in your engine the size of that clip or those paper clips, there's much bigger problems than a drain plug can solve and the filter would catch those anyways. The tiny particles were much more realistic. Second, room temperature oil is much thicker than the hot oil flowing through the engine, so heating the oil to around 200 degrees or using a much thinner oil like diesel would be a more realistic test. Finally, I think your expectation that the plug should catch all the pieces in a few seconds of shaking is unrealistic since it's job is to help keep the oil free of metal particles over several months and many hours of running rather than fully cleaning cold and unrealistically contaminated oil within a few seconds. I have both a magnetic oil drain plug and a magnet from an old hard drive stuck to my oil filter for piece of mind. I have never seen an oil pan designed in such a way that the extra length of a magnetic plug is problematic, but that's a good point in case someone has an oddly designed oil pan where that's a concern.
I agree! Great explanation and approach of looking at the test. My test was laid back but you took a more scientific approach and that helps people understand different conclusions better. Thanks!
@@mannybudhu3905 Why would you want to stick the magnets to the oil pan and how could putting magnets on the filter be counterproductive? I would rather not have to remove the oil pan to clean out the accumulated metal particles since I could stick the magnets to the filter and discard them with the old filter. Also, a lot of cars have plastic or aluminium oil pans, which a magnet won't stick to.
@@averyalexander2303 Yeah...I have read conflicting stories on where its more effective.....my rationale is that since oil is clean outwards from the filter...you're basically putting the magnets close to filtered oil, placing the magnet close to the drain plugs and removing the magnets just before a drain, would allow the drain pressure to flush the particles out. At least that was my theory..I plan on testing that soon.
@@mannybudhu3905 Either magnet will be effective. I'd guess a filter magnet would be more effective than a drain plug magnet since the oil is actively flowing through the filter and the magnetized surface area is much larger, but a magnetic plug isn't a bad option either. They do work, I have several of them. Heck, as cheap as magnets are, get both if you want. Won't hurt anything. From my experience with magnets in transmission pans and diff covers, the oil flowing past the magnet as it's drained won't remove the metal particles. They seem to become magnetic and stick to each other and the pan like a magnetic grease even after the magnet is removed. For this reason, I wouldn't put a magnet on the pan because I don't want to be frequently removing it to clean the metal particles the magnet captured.
@DriversTherapy redo experiment please with a dollar store waterfall or a cheap transfer pump $17 for a 750 gpm pump, (5 gpm is a high flow LS oil pump). An aluminum cooking pan from Walmart can be folded, but it's best to just get an actual engine oil pan from Amazon and then return it after the test. The baffling in oil pans prevents the cavitation by the shaking. Maybe I should start a youtube 😆

Wow! That makes sense because of the oil filter's job. Thanks for sharing, cool info!

It’s not a bad idea. The only thing I would worry is getting random road debris on it.

That makes slot of sense! Thanks for providing that info.
Helps on motorcycles being that the wet clutch is running in the same sump as engine oil.
That makes sense :)
Interesting experiment.
Yes it was 😎

Just buy a powerful magnet on ebay....slap in on to the oil pan...remember oil pan not the oil filter...as that can be counterproductive....

Is your drain plug, cusco?
Yes.
Imagine if the bottle was upside down and allowed to fall to the sump. Then it's suck the oil and not shake the whole tank
Good point. I can see that.
