Magnetic Oil Drain Plug or Not?

[ski.dive]

I'll be changing my oil this week, should I buy a Magnetic Oil Drain Plug and install it?

The responses I've always read on the positive side are that it does retain iron filings. Ok, I know that was obvious. I've had a couple vehicles I've bought used which someone must have put a magnetic plug on it. Mine didn't catch a whole lot of filing, which was a good thing.

The negatives can be that the filings may get knocked off (en masse) from turbulant oil at high revs, in which case it could send a larger amt of filings, or a 'clump' through the system rather than lots of filings being evenly dispersed and suspended in oil throughout the entire motor. But I would think if you change your oil regularly and clean off the plug, it would be ok, and not many filings would build up.

That said, I haven't had magnetic plugs on any of the vehicle's engines I've run up to the high 200k or even 300k miles. The engines were still operating ok at that point, but rest of the vehicle had pretty much rusted/worn out.

Unless your running your engine at several thousand rpm for a really long time and you've removed the baffle plates, you're unlikely to knock anything off the magnet, and it will get caught by the filter anyway. The screen on the pickup tube is pretty fine so you're unlikely to suck anything up that is big enough to wreck the pump, and if you have pieces that big, you're already in trouble.

Magnetic drain plug is good to have to keep an eye on the engine.

I have a magnetic drain plug on some of my vehicles and mostly I just wipe off the black mark (if at all) like it's a small felt tip mark on a paper. If you get chunks on the drain plug chances are your engine is making bad noises long before your next oil change.

I use the Fumoto drain plugs. Makes changing oil so much cleaner.

Agree. I always used them.

That is, until I installed the FUMOTO!:giggle:

Third endorsement for the Fumoto. One of the best things you can put on your truck.
