Magnetic oil and ATF drain plugs by Goldplug

I installed goldplug oil plug on two cars about two years ago. Here are my results, your mileage may vary:

- '07 Prius w/ 65K mi: magnetic plug attracts very little material. For the entire 5K mile interval the oil stays clear and clean, no losses and scarcely any discoloration.

- '96 Corolla w/ 130K miles: The magnetic plug picks up fine, dusty particulate, enough to spread over the tip or your finger. The car loses ~.5 liter every 1500 miles which I attribute to some burn off due to high milage plus a small oil leak in the crank case gasket (I'll have that fixed one of these days).

I, too, like having the added "filtration" effect of a magnetic plug and it gives another way to monitor engine wear and tear.

 

Thanks for including the part numbers. I got two of the oil drain plugs since I plan on keeping both of my silver pine mica Prii for eleven more years.

 

I've had mine for a year and a half now and am very happy with it. The first oil change I used with it had some mud like metallic goop on it, however the following oil changes had less noticeable goop. I think it's doing a good job. Bumping this old thread in appreciation for Op's suggestions....

 

Since oil is frequently changed out of the engine and that it has an oil filter, I don't see that much benefit from a magnetic oil drain plug.

In early water cooled Porsches up to 2008, where the intermediate shaft bearing has a tendency to fail. a magnetic drain plug is a good precursor of an engine life ending event.

The Prius transaxle, however, can benefit with a high strength magnetic drain plug.

As I discovered, even the weak little Gen II OEM ceramic magnet in the transaxle drain plug gathers a lot of steel and iron particles, which might have otherwise been allowed to circulate as an abrasive medium through the transaxle again and again.

From my experience, even the weak magnet has been eliminated from the Gen III Prius models.

While the hex plugs were a little expensive, they are convenient to use.

Now, comes 2015, and I'm considering getting OEM plugs from a Toyota dealer, milling them out and securing neodymium rare earth magnets to them.

For Gen II Prius models, the 10mm hex socket drain plug can then be used as the fill plug, like on the Gen III Prius to retire the shallow hex 24mm fill plug.

The Gen III Prius models have the most to gain, because there is NO magnetic plug AT ALL.

 

NEW development...neodymium "rare earth" OEM type drain plug kit.

If Toyota supplied one, this is HOW they would make it.

No need for an odd size hex socket to install and remove my new magnetic plug. This plug is made from a GENUINE OEM Toyota Prius transaxle drain plug.

I took an OE plug and milled it out to take a special extra high strength N51 neodymium button magnet and secured it with JB Weld standard slow hardening epoxy steel, which is stronger than the Qwik Weld type. It when then baked in an oven for an hour to fully harden.

I've attached photos of my new type holding a 1-1/2 inch combination wrench suspended, a Gen II "small ceramic plug removed during a fluid change and a NEW Gen II plug showing the small ceramic magnet.

If you have Gen III with NO magnet, this would definitely be an essential upgrade.

 

Looks like you're going to have to start your own magnetic plug business Mike!

 

No, it's NOT really a business. I'm retired. I just enjoy experimenting and improving what I can't buy. It keeps me busy and keeps me learning and thinking.

And, I just want to share my ideas.

 

I purchased Qty 2 Gold Plugs on 2/1/15 and have yet to receive product. I've reached out to the company several times with no response. Seems like an odd way to run a business......

 

Talking about using magnetic drain plugs make me wonder how much metal from the oil gets stuck on the MG rotors. These probably have some of the strongest magnets available.

Don't know why everyone is considering "Gold Plug" with it's non-Metric large head? Mine uses the M10 hex socket and are made from genuine Toyota transaxle plugs.

I know one thing. Porsche owners are snapping them up as fast as I can make them. They are much superior to the aluminum M8 socket ones that are easily stripped out.

 

Sorry to hear about this! I hope this was resolved to your satisfaction. I found your order, but no other contact. Did you call our Toll Free Number? We have been having problems with it this year, but I think we have that resolved.

Let us know!

Hi Mike,

If you want a smaller head 18mm plug, you would want our MP-10. It has a 19mm (3/4") reduced hex head. Most people like the AP-05 because it more closely resembles the common Toyota 18mm plug (Low Profile)
