Magnetic Oil Plug?

[czarwolf]

Good day all,

I was wondering today as I am filling up my amazon list with misc parts for my bike, I came across magnetic oil plugs and thought they sounded interesting! and useful with an older bike. But then I have heard stories about the magnets coming off from heat / wear and shooting off thru the motor leading to most epic failures, But I digress. What is the community thoughts on Magnetic oil plugs? Worth the 9 bux or stay with the standard?

I would stay with the Honda OEM part.
Why mess with success?

+1 with fnmag on this one. If you see metal swarf when you change the oil, time to start looking inside the motor!

If it was constructed like the one you already have in your final drive case - did you know about that? - then it would be OK to use. The drain plug in the final drive has the magnet staked in place. It won't come out.

IMHO, the bad shavings that might turn up in your engine oil would probably be bearing materials, which are probably non-magnetic--unless there are bigger problems than bearings. This is IMHO, so I can be schooled on this concept, if anyone here has had experience.
Unless the magnet becomes detached and somehow floats into moving parts, it can't do any harm to have a magnetic oil drain plug.

Don't waste your time or money. If mother Honda wanted a magnetic plug there she"d would have done it. Besides thats what your oil filter is there for.

I had one in my 305/CL77 and there were some metal bits from time to time. Honda has an OEM version and there was a pricey but high quality one mention somewhere here. I'm considering one just for the heck of it. And it has the added benefit of making people feel good by telling me I wasted my money.

there is probably metal from the trans and thats why there is a magnet in the case . Magnets are always in car auto transmissions. They get covered in what I would call metal dust from all the planetary gears.

Stick a magnet on the end of the oil filter. All done.

Depends. I just picked up a new wheel bearing (roller for a GMC truck) off my desk and tested it. Yup, all magnetic. I'm assuming there are roller or ball bearings somewhere inside the engine. Main brgs are, of course, nonmag.

While he's at it, if he sticks one on his rubber fuel line he will increase his mpg at least 100 fold. Oh, you have to use the special magnet from the ad for $19.95?

I think I recall JC Whitney selling a special stretch belt or buckled belt magnet which went around the oil filter to trap particles. Might work just as well.......

Based on the strong recommendation of a mechanic I trust, I’ve used the Dimple magnetic oil drain plug in a few different bikes (all Honda) for several years now.
Pleased with the product and amazed by the “gunk” it traps.

I have always questioned whether there is truly a benefit to an engine oil magnet. Foreign matter circulating in the oil will be trapped by the oil filter. Anything to small to be trapped by the oil filter will continue to circulate through the engine. So the question becomes does having particles small enough to make it through the oil filter circulating in the oil pose any danger. I suspect not or there would a lot more engine failures as the overwhelming majority of engines do not have a magnet in the oil system. At the same time there is no negative effect to having a magnet so if it gives a person peace of mind that might be worth the cost to them.

100 fold! OMG, @ $19.95 that's a screaming deal.

The problem is particulates. Since the oil filter is made to bypass at a certain differential pressure, many particulates bypass the filter. So, every method available helps reduce the risk. Experience tells us failures occur over time. Making oil testing a benefit. Building a machine that is not prone to failure, has proper lubrication, not overloaded is the best medicine. Unless a failure occurs the particulates generated in an engine will be inside of tolerances. If a failure has occurred causing large particulates it doesn't matter any more...…..the engine will be toast before you know it......jmo

The only thing that's going to make your machine last is doing proper maintenance. That includes using the specified lubricants, parts, and time intervals. Your owners manual should have this information. Never heard of a magnet saving a motor but hey to each his own.
