Frequently Asked Questions about our magnets:

Why did you develop this product offering?

As auto enthusiasts, we are concerned about the cost of fuel/oil/routine maintenance for our cars. This product offers a way to extend the life of the engine by reducing the wear on rotating parts. It also extends the life of the oil by removing particles that are never trapped by an oil filter. Oil changes can be extended by thousands of miles. That saves on maintenance costs and cuts down on the amount of oil needed thus reducing our dependence on foreign oil.

Where do all these particles come from?

These particles are a result of normal wear and tear of an engine. At idle your car engine is rotating at 600 rpm with each piston going up and down 10 times per second. You can't even move your finger 10 times per second, a lot of rubbing going on down there. How about at 3000 rpm or 50 times per second? How about our racing friends when they are going 6000rpm or more? That would be 100 times per second. Now that is a lot of rubbing going on. This is where all the finite (small) metal particles are coming from. Not unlike the thousands of skin cells that fall off our bodies every day, but they are replaced with new ones. The metal does not. The more particles exist the more are created, they act like lapping compound and take off more metal. We make it tough for them to reproduce because we keep the metal particle population floating around in the oil down to a minimum. (Forgive our analogy but it helps people understand the concept.)

What are the magnets made of that makes them so strong?

Our magnets are made of high grade Neodymium. Neodymium is a rare earth metal, atomic number 60, discovered by C. F. Ayer Von Weisbach a scientist from Austria in 1925. When this rare earth material is mixed with iron and boron, you have created the most powerful magnet in the world! As in just about everything else in life there are different grades of Neodymium magnets as well. You can be assured our magnets are of the highest quality, specifically designed for the application intended.

Why place the magnets on the outside of the oil filter?

In all spin-on oil filters, the oil is pumped into the filter before it is channeled to the bearings. The flow of oil into the filter enters from the outside part of the filter, through the media (Filter material) into the center and directed into the engine. We wanted to capture particles before they enter the media. The particles are snatched out of the oil stream as soon as the oil comes into the filter, capturing all the ferrous (steel) particles to the inside wall of the filter housing where the magnets are. This is great because the filter lasts longer this way, it is not damaged by metal particles ripping holes in the media under hydraulic force and it does not fill up nearly as fast.

What is the purpose of putting the magnets on a drain plug?

In 1932 manufacturers began using magnets on drain plugs on cars and trucks. Today most manufacturers want to save the additional cost of a magnet and they feel it will get through the warranty period without it. Perhaps you changed the oil on your father's car and recall wiping that gray mud off the drain plug! Yep, that gray stuff was metal particles captured by the typical low powered alnico magnet mounted on the drain plug in those days. The drain plug is removed when you change your oil. It’s an excellent place to put a magnet because you can remove it and clean it. Well, those older alnico magnets helped some but how helpful would the most powerful magnets in the world be? Like one hundred times more powerful!

Do the magnets loose strength over time?

No, ours will not because they are a special high temperature Neodymium compound which are effective to over 300F. Regular Neodymium magnets will loose strength at 175F and above. If you get your magnets from us you know your getting the best. They will last forever. Some words of caution here:

Neodymium magnets are very strong but are also mechanically fragile.

There are some health hazards of note. Neodymium magnets should always be handled carefully. Strong magnetic fields can disrupt the operation of some internal medical devices such as pacemakers. While most solid state electronic devices are not affected by magnetic fields, some medical devices are not manufactured to mitigate the effects of strong magnetic fields. These design flaws can be hazardous to patients using these devices. If swallowed, neodymium magnets can cause lethal conditions by joining up inside the intestine.

Neodymium magnets are made with special powders and coatings, so they are very fragile. They are often plated with a metal such as nickel. The magnets can fracture at temperatures over 150 °C, or under impact as a result of their own acceleration. When this happens, in some cases the magnets may break apart so suddenly that flying pieces can cause injury.

Caution must be taken when using neodymium magnets. A neodymium magnet is powerful enough to destroy the contents of a floppy disk to such an extent that the information is unrecoverable, a guarantee not present with techniques such as formatting the disk. In addition, neodymium magnets are one of the only materials that can successfully erase the information contained on the magnetic stripes of credit cards. Neodymium magnets are often strong enough to not only magnetize color CRT metal shadow masks, but also physically deform the mask itself. Such damage is typically not repairable by degaussing.

Never put the magnets in a fire, their fumes are toxic.

Can’t you use regular magnets?

Life is too short to spend your time working with inferior magnets, spend your time wisely. There is no comparison.
