I don't know about magnetic drain plugs but I do know that watching Ari in his shop is good for my bike's mental health.

I stick a strong magnet to the outside of my oil filter. All the benefits with no risk and no need to clean it either, just take it off and plonk it on the new filter when servicing.

Once I learned how to do maintenance on my own truck, I started using magnetic plugs on everything. Truck, motorcycle, lawn mower. It was particularly helpful on my truck with the transmission, transfercase, and differentials. I always take photos of what they look like and note interval miles. So I have a very good baseline of what normal is. That way when something doesn’t look “normal” I know to investigate for trouble.

When I put my magnetuc drain plug on, I looked at it as more of a visual indicator. That way if I get particles bigger than the typical "fuzz" then I know there's something that needs to be addressed. I didn't know they offered the filter magnet though, that's pretty neat.

Thought I'd ran out of things to buy for the R1 - time to start researching magnetic oil filter rings!

I added a magnetic "Gold Plug" to my Grom since it only has a screen and an oil 'spinner'. I'm confident that it will make no difference in my life, other than bringing me great satisfaction each time I wipe away the buildup of ferrous sludge. Money well spent 👍🏻

Not gonna lie, you had me a little worried 😅 I’ve been running magnetic plugs on mine and my wife gsxr750’s for years and now on our z125’s, so I’m glad to see this is Ari approved! ✅ 😉

I've watched countless of these type of videos, but being a mechanic and enthusiast for over 15 years, I don't usually learn something from it. but I have never heard of a donut magnet on the filter! I've seen people just attach a few magnets to the outside of the filter though, pretty much the same thing, but could possibly come off.

BMW supplied a magnetic drain plug with my G310GS. I was shocked at the initial 600 mile service when I drained the oil and there was essentially no particles adhering to the magnet - certainly no chips. There was a very thin film of particles that were individually too small to see. I remember Fortnine doing a video about debris in break-in oil as a measure of engine build quality. On my pickup truck, I stick two large rare earth magnets on the outside of the filter to trap magnetic particles inside the filter. I never cut the filters open to examine them (as I did with my airplane) so I never knew if my truck engine was "making metal". It's a Toyota and I use full synthetic oil, so presumably not.

My last 3 new bikes Benelli 900 Tornado Husqvana 701 MV Agusta Brutale have all had steel magnetic drain plugs fitted from new by the manufacturer!

I’ve used the VERY strong rare earth magnets from old computer hard drives for years. I’ve just slapped two or three on the outside of my oil filter. I honestly have no idea if they are helping but it amuses me to think so, there is zero downside , zero cleanup and they swap to the new oil filleted on every change. Open to thoughts and suggestions, thanx to SM for letting me know there is an internal ring magnet as an option as well!

all models of drz400 have a magnetic drain plug standard. a magnet can catch a large chunk before it destroys another moving part.

Hate to sound like a fanboy but well done Ari. Never thought about a magnetic ring for the oil filter. Thank you sir.

One thing to note: For many bikes (maybe all bikes ??), the oil pump is 'before' the filter. Have a magnetic plug to help gather larger chunks that would be caught by the filter anyway, before they get into the oil pump, would be a plus

"Could stick Bob Dylan knows where" 😂😂 never heard that before

oil filter magnet. good idea. also you can put magnets on outside of oil filter.

I've always used them in bikes that didn't have a filter. My two-stroke dirt bikes don't have filters on the gearbox oil so it always made sense to me in that application.

One thing you want to be careful with installing a different drain plug in general is the height of the bolt head of the drain plug. Depending on the bike you don't want the bolt head part taller than your stock one. Like on my DR650 if you get a taller plug it sticks out past the skidplate and if you go over and rocks you may bus it off and have a bad day.

The round filter magnet looks like it may be partially restricting oil flow. But I do agree with the theory of a magnet on the filter. They make ones that go around the outside of the filter. I use magnets out of old harddrives stuck to the outside of the filters on all my equipment.

Drop a small radio shack magnet down the center of a new oil filter is an old zen motorcycle trick, it's like an ounce of prevention....

Ive done that for quite a while now, a super strong magnet from an old broken hard drive on the outside of the metal oil filter. easy and super cheap.

Yes they work but what alot of people forget is most 4 stroke motorcycles have other magnets already inside the engine, very strong ones. Most bikes have a oil cooled stator surrounded by a flywheel containing a large number of very strong rare earth magnets. Some bikes have a oil bleed off the crankshaft that keeps quite a significant amount of oil spraying across it. Some have dry stators and run magnetic drain plugs. I have seen high mileage bikes with customer installed magnetic drain plugs come out pretty clean only to pull the stator cover to find a alarming 1/32"-1/16" coating of powdered metal dust adhering to the flywheel magnets. Most look black till you wipe with a rag and suddenly it's silver. I have also seen a magnetic drain plug find a piece of broken roll pin in a fairly new Suzuki Hayabusa during a oil change

other best tip - stick a couple of neodymium magnets on your oil filter on the outside - job done :)

My Beta 2 stroke came with a magnetic drain plug for the gearbox oil. Glad it is doing it's job!

I'm surprised this guy didn't talk about high temperatures, which can de-magnetize some magnet types. Some of the strongest magnet materials can lose their efficacy after being subjected to the high heat conditions of motor oil.

I don't normally jump into these things but. I have a 2010 CVo street glide and I have run a filter magnet and mag drain plugs since new, I only use K&N oil filters and AMs oil and have 276,000 trouble-free miles on it. and that's changing the oil every 7500 to 10,000 miles. So for me its just cheap insurance and one of those things that cant hurt

I've been using Magnetic Drain Plugs as well as PC Racing Billet Aluminum Re-Usable Oil Filters that have a magnetic built into them since 2010. Very happy with them..

TIL I can put a magnet on the oil filter. Thanks!! :)

One could also just buy a KTM. With its two drain plugs, two oil screens and a filter it's pretty good at catching the crud.

A magnetic drain plug is not for removing small particles from oil. They are for detecting the onset of excessive wear when you see larger chunks that are symptomatic of a larger problem that can be corrected before catastrophic engine failure. The correct nomenclature is “chip collector” to detect large chips being shed from the bearings. They have been used on aircraft engines and heavy machinery for about 100 years.

Buy a small neodymium magnet and attach it to your oil filter. When you change the oil, move the magnet to the new filter. The magnet shouldn't fall off your filter, but if you're worried you can tape it to your filter.

It really helps if you do an oil analysis when trying to answer this question: The Fe content of an oil drops by ~50% just by using a magnetic sump plug. Iron is a major oil contaminant in most engines... so removing it will reduce wear and extend the life of your engine oil: The additives in particular will last longer You might be able to remove a little bit more ferrous metal (iron/nickel/cobalt) if you use a bigger or stronger magnet e.g. Oil filter magnet. If you listen carefully you can also hear the difference when using a magnet: The engine is slightly quieter. The reduction in noise is due to less circulating particles. Less noise = more power (less friction) 🙂

Another bonus is that it may catch a large chunks or a screw that's come loose before it causes a ton of damage and it lets you see these big pieces instead of just washing them away. Found bits of circlip on the magnetic drainplug of a dr650 which alerted us to a bigger problem. Ended up having several transmission gears replaced under warranty by showing them the pieces that had been collected on the magnetic plug. Would've been so easy to to just drain those little bits out and we never would've noticed.

I do not like bikes but I am a car guy who works as a mechanic. Most automatic transmissions I have seen have a magnet on the bottom of the pan from factory. I bought a few really powerful magnets and have put them on my oil filter, diffs, transmission pan, and oil drain plug. After some time you WILL notice how much crud these things will pick up. The main thing is proper maintenance and regular oil changes, the magnets are a bonus not an excuse to run your oil longer.

Recovery looking good man. Glad your face is doing good!

Kinda funny, just made my oil change on a Yamaha XJ750 Mid-Max 1983 and found out some sludge on my magnetic drainplug from factory. Got scared and made a compression test without having any issues. You just secured what i thought that it was normal wear. thank you !

I use a magnetic strip that wraps around the outside of the oil filter. So never have to worry about magnets breaking and falling into engine.

I always put strong magnets on my spin on oil filter. I guess it is effective judging by the video but I did notice when it came time to change my oil, the oil still looked to be a good amber color

Awesome video, as always! Anything with Zack and Ari in it is what I like to see.

Funny because both my 1982 Suzuki GS750E and 2004 GSX750F came factory with magnetic drain plugs. I simply replaced the gaskets every couple years, wiped off the magnet and put it back in. Something about small high revving 4 cylinder motors..............makes a magnetic drain plug make sense.

It makes sense to use this on motorcycles! Fair enough car engines are mostly aluminium with aluminium pistons, gearbox’s usually have a magnetic sump plug therefore would make sense to use it on bikes because bikes transmission and engine share the same oil

I think it's a nice indicator to have. What if you remove the oil plug and you see a ton of metal filings and bigger pieces of metal, then you know something has happened. Easier than looking through the used oil. It also helps prevent keep any metal to reach the oil pump and oil filter, prolonging their lives.

Great, didn't know about magnetic filter washer

Two weeks ago I had an expensive PSR predrilled drain plug fail and lose the magnet in my track bike after 220 miles between changes. Thankfully I was able to retrieve it by running a strong magnet along the bottom of the oil pan. Never again!

Ah! Magnets! Can we also have a discussion between paper air filtes vs "high flow" air filters? How does it protects the engine and what are the long term effects!

You’re just so good at this, you bastard. I appreciate this sooo much. Now my g310gs needs a magnetic drain plug.

Glad to see you back!!!!! We miss your wisdom!!!!

It definitely works for my moped which only has fine netting kind of filter.

My Tuono has a magnetic drain plug from the factory and I use a gold plug magnetic plug on my grom. Always get at least a little bit of sludge

My KTM Duke has strainers with magnets before the oil filter. Some auto manufacturers have them as well.

Manufacturers don't include magnetic drain plugs because the company is on the hook through the warranty period only, and (of course) because the magnets are an unnecessary extra cost. Of course motorcycles typically don't fall apart as soon as the warranty expires and the additional protection of an oil plug magnet won't make much difference during the early warranty period, but additional protection really comes into play with long-term ownership. Bottom line: nobody has yet proven the use of magnets actually prolongs the life of their engine, but it sure can't hurt. I use magnets on my canister filters as well -- the goop immediately disappeared from the magnetic drain plug as soon as I started using filter magnets, so I know they are doing something! Thanks for the video.

One issue that can come up with magnetic catchers is: if the blob on the end of the magnet comes loose, you now have a coherent lump of metal fragments floating around in the oil rather than individual particles in suspension. That _could_ block oilways or cause short-term starvation -- but I've never seen it happen myself.

Just stick a small strong magnet on the outside of the drainplug. The plug is then magnetised.

All older Grom, Monkey as well as current C125, CT125 and most small air-cooled 125cc bikes only have inefficient centrifugal filters. There magnetic plugs really come in handy. In the small Honda's, the drain plug is also right before the oil pump as these bikes have very shallow sumps.

My pops would always drop a big magnet at the bottom of the oil pan if it ever had to come off for any reason.. A crack, broken, stripped drain plug. I still do this with all my vehicles..

I have a 2019 Suzuki GSXR-600 and it came with a magnetic drain plug from the factory, actually caught quite a few chunks of metal on it so glad it was there lmao

There is always something new to learn.

I didn’t realize Ari worked at Revzilla until now. That’s awesome, Ari is a good dude!

Got a piece of neodymium magnet on the back of my original (car) oil plug. Works like a charm :D

I put magnet 🧲 inside the tank on my old cruiser. It works like a charm 🤠.

"...can stick Bob-Dylan-knows-where"! 😆

You can also put a strong magnet on the outside of your oil filter and it will attract the particles to the walls of the oil filter.

I... Never though about this. This was really great content. Thanks.

I am thinking about making my own magnetic drain plug by gluing magnet(s) to an existing plug. Actually, gluing 3 or 4 to extend the side area & height exposure and thus, pull/attraction. Questions: 1. Would the greater area/exposure of a multi magnetic stack be more effective than a single magnet? 2. Is using an earth magnet better than a regular magnet because it is stronger and has more pull? 3. Will Epoxy Glue be a strong enough adhesive? If not, what would be better? 4.Should I rough up the surfaces of the plug and magnet(s) to facilitate better adhesive grab?

Speaking of particulates in the oil, can you go over oil drain intervals. Most sportbikes today recommend 8K mile intervals even with conventional oil, but I find that a bit long considering the oi is shared with the gearbox. Used oil analysis reports regularly show oil viscosity reduction as soon as 2500 miles ornso with conventional oils n

Good review! I have magnetic plugs on the Honda engines without oil filters, like my log splitter and wood chipper...essential!

As someone who doesn't have a mechanical mind these videos are very helpful.

Great tips with this video. I'm going to get some magnetic washers to install on the oil filter. Much more feasible than the drain plug.

Wow! Magnetic Donuts! Love learning about them! Thank you!!!

Great video brother

A couple of tips not mentioned......one can put a magnet on your oem drain plug on the outside...or attach the magnet on your oil drain pan close to the drain plug or plugs. Remove magnet or magnets just before you drain your oil during an oil change....and the metal particulates (Unless you have a Yamaha or Honda engine) will flow out of the drain holes as your oil is draining during an oil change. You can also add a magnet on the outside of your oil filter. These outside magnets one can add have a stronger magnetic attraction...cheaper....and reusable...Therefore...overall....mo betta...

The thing that really convinced me to start using magnetic plugs was that they are required in air crafts and are used heavily in the professional trucking industry. Look at where peoples lives are dependent on engine performance. consumer manufacturers will never give us a product to last forever.

I have a Virago... Yamaha put a magnet literally right under the starter motor, to catch shavings from the gears that don't catch. My drain plug is a backup

I think it probably wouldn't make to much of a difference for most people if they have one or not, but if you're like me and plan to keep the same bike until you can't ride anymore, you might want to have one to give the engine the best chance at living a long life. If the 10 dollar drain plug adds a few thousand miles to the life of the engine, it's worth it to me.

Thanks Ari for all the knowledge and tips!!!👍

My bike is a Honda CN250 (Helix, giant scooter). The bike doesn't have a proper oil filter, just a little metal screen to catch very large particles. Based on this, I think adding a magnet to the system would be a good idea. Not to just figure out where to put it.... Edit: just finished the video and got to the part with the donut magnet. That seems perfect. Honda Helix seems like a perfect candidate for this.

Stuff I never knew about drain plugs. Thanks' bud.

Thank you I was worried. Had shavings on my new plug, but couldn't see any on the oil filter. But was still really worried.

0:14 I see Ari got his hand on one of them Japanese drain plugs.

I put one on my grom for the first break in oil change mainly because it had me a little nervous not having a filter

Manufacturers don't put on magnetic oil plugs because they don't want you to panic at the first oil change when your oil is full of metal shavings...

damn oil filter magnet never heard of those. awesome i'll buy one of those!

I have a tip for everyone wanting a magnet plug. You know those old spinner hard drives that are now useless? Well as an I.T. tech I get them and i take them apart because inside is a powerfull little curved magnet attached to a weird metal bracket. You can use a flst head to carefully pry it up and off so you get a perfectly flat C shaped magnet. I got bunches of these so i put one on the back of the drain plug on my car and motorcycle. Also, i put one on the bottom of the trans case. All my plugs are steel so it sticks perfect and they are really strong so wind, water etc wont take it off. One time I was lazy and took my car for an oil change instead of doing it myself and the oil place stole it. 😆 Luckily i have like 5 or 6 laying around. This way you keep your original plug and magnetize it easy. I do like the ring magnet on the filter. Makes for sense. Maybe ill try one of those also.

Thanks just bought motion pro oil filter magnet

Just magnetise your OEM drain plug like how we magnetise our screwdrivers. The magnetise effect can last up to 2 months. I ride very often to work and so on so every time I change my oil I would redo the process. It takes 5 minutes and saves me the 30bucks and a potential breaking hazard. Of course if you do your oil change at a workshop it'll be a different story

Never knew about the donut magnet, makes a lot of sense. Great video as always! I thought you might have addressed the argument that a magnetic drain plug can have build up, potentially releasing a large amount of metal into the engine at one time. Frequent oil changes can likely avoid that, but we all know we're capable of "extending" oil change intervals.

Great video as usual. Explain stability control with IMU?

Drill the stock drainplug and ad a neodymium magnet to it :)

Votex sells magnetic drain plugs made from stainless steel. While the drain plug sold on the link provided by this channel is aluminum because it is available in different anodized colors.

And the issue that everything that goes into the oil filter has already been through the oil pump. the oil pump is the first inline for the oil system and is ahead of the oil filter in the lube circuit. The sump plug magnet will prevent some metal from getting into the oil pump and damaging it

I use a superstrong mad on the outside of filter. Nothing to clean, remove old filter, take off mag, place it on new filter, all the crud stays in the old filter.

I go to harbor freight and buy a pack of neodymium magnets and place them in a pattern around the outside of twist on filters. Occasionally need to pull bits picked up from the road but normally I just need to move them from filter to filter.

So actually I have run across a one motorcycle and several automotive engines and transmissions with magnets. Some of the applications with magnets were automotive manual transmissions without a filter, and several others were automotive automatic transmissions which did have a filter.

I wish Ari had a podcast, I swear I can listen to this guy for hours.

My bike doesn't have a filter nor strainer, it has a screen with a little magnet attached to the drain plug, I'd clean up the screen and magnet every oil change, very convenient indeed

Used to just stick a neodymium magnet to my steel drain plug.

The doughnut magnets look like they partially block the filter drain holes affecting flow rate?

Yamaha SX 650 1969-85 came with two magnetic drain plugs. One for motor the other for transmission. Wise investment from Yamaha into that model.

Excellent info. Thank You.
