Not really an S2000 specific topic... But just wanted to see if any of you have had any experience using these...

Good idea?

I believe the general consensus is if you need a magnetic drain plug for your engine oil, you're gonna be screwed regardless.

Our diffs do have a magnetic drain plug (rightfully so), and you will normally see some residue on that even with normal driving (w/o abuse).

Just drive the car and don't worry about it.

 

It's unnecessary but if you want to use it then go for it. To me, it won't help prolong the life of your engine.

 

Thanks for the feedback... I wasn't stressing out on removing metal particles from my crankcase...it was just an interesting product, and I was wondering if anyone had any experience is all...

Interesting...they also have magnets that you place on your oil filter to keep metal particles collecting in the filter...

 

Bought one for my TSX for "safe measure" and my Subaru came with one. Doesn't make a difference IMO, it's just one of those "peace of mind" things to have on your car. If you have the $25 or so extra to get a magnetic bolt for your oil pan, sure why not? But if you're hungry and want to eat out for lunch, I think that's money better spent. Happy motoring!

 

Magnets only pick up magnetic particles. Most wear is caused by particles of silicon ingested through the intake past the air filter, not by iron particles. If larger iron (steel) particles existed in your oil, the oil filter would pick them up.

In the field of engine lubrication and filtration, wear metals in the oil are looked at as products of engine wear, not as the cause.

I believe that a magnet can't hurt and might prevent a small amount of wear but it won't make a noticeable difference over your engine's life. I have 330,000 miles on my car and I've never used a magnet. If you are interested in reducing engine wear there are other things you can do that are more effective.

 

How much iron is in our engine? If you see metal on a magnetic plug - I would think you have long known of an issue with the engine.

 

In 1964, the bad old days of the British motor industry I pulled a new Hillman Imp motor, with just 36 miles on it, apart to prepare it for the Bathurst 500 mile production car race. They certainly could have used a magnetic sump plug. I got 2 teaspoons full of machining swarf out of the cam shaft alone. I'm sure no Honda, or other mainstream manufacturer would produce anything like that today. No engine will produce much in magnetic bits before it is well past saving.

I do believe however that the are a very good idea in gearboxes. Just one botched change can produce bits of steel large enough to do damage if left floating around the place. My TR7 has one in the gearbox, & every oil change, despite my perfect gear changes, there is always a small amount of fine grains of metal on it.

 

$35 for a tiny magnet. pffft.

I have one that wraps around the oem oil filter. Now THAT'S a magnet!
