A fool and his money are soon parted\u2026 usually by a snake oil salesman. Similarly, an uninformed car owner and his cash could very well be split apart by an unscrupulous service adviser at a service center.<\/span><\/p>\n

The latest snake oil being slung in service centers and workshops is an oil filter magnetic trap that\u2019s often recommended by the foreman or service advisers.<\/span><\/p>\n

\"Car<\/p>\n

What Is an Oil Filter Magnetic Trap?<\/span><\/h2>\n

If you\u2019ve not heard of the device before, it\u2019s a magnet that fits around or under the oil filter on the engine. Purportedly, the magnet will isolate metal particles within the oil as it flows through the filter and keeps said particles trapped within the filter. This keeps the oil cleaner from residue and should therefore improve the life expectancy of the engine.<\/span><\/p>\n

Now you might be thinking, \u201cIsn\u2019t that the primary purpose of the oil filter itself?\u201d And you\u2019d be right.<\/span><\/p>\n

Most of the people pushing these oil filter magnets are banking on the fact that it usually costs under RM100 and you\u2019d therefore not think twice about giving it a go. After all, even if it doesn\u2019t function, it\u2019s not going to cause actual harm, right?<\/span><\/p>\n

In theory, the principle behind it isn\u2019t wrong. A magnet powerful enough should hold the metal particles within the oil filter instead of allowing them to flow back out into the engine.<\/span><\/p>\n

Nonetheless, the chief function of the oil filter is to prevent that from happening anyways. We know redundancy is a good thing but if the oil filter isn\u2019t doing its job, all the oil filter magnets in the world aren’t going to prevent your engine from undergoing catastrophic failure.<\/span><\/p>\n

Within an internal combustion engine\u2019s block and head is a maze of passageways for the oil to circulate around and lubricate all the necessary moving components to reduce wear and prevent friction.<\/span><\/p>\n

The oil is picked up from the oil sump at the bottom of the engine and pumped through the oil filter by the oil pump before it circulates and returns to the sump.<\/span><\/p>\n

Any contaminants within the oil such as metal particles or residue will be trapped within the filter.<\/span><\/p>\n

Why a Magnetic Trap Won\u2019t Work<\/span><\/h2>\n

A magnet on the exterior of the filter won\u2019t be contributing anything to the filter\u2019s functionality due to the fact that the impurities will get trapped in the filter element and remain there because of the positive pressure generated by the oil flowing through.<\/span><\/p>\n

The oil pressure required within the engine to ensure proper lubrication ranges from around 10 PSI at idle to well over 60 PSI as revs approach the redline. That\u2019s almost double the air pressure in the tire.<\/span><\/p>\n

Additionally, there just isn\u2019t any substantial data on the effectiveness of these magnets. Obviously, the people selling these magnets will conjure up plenty of evidence to back their claims but there\u2019s a distinct lack of evidence from neutral parties to justify the magnets.<\/span><\/p>\n

Among the many pieces of evidence presented by the sellers of these magnets will be similar to the demo above. The magnet on the bottle will attract the metal particles within the oil and hold them in place.<\/span><\/p>\n

In fact, this very demonstration to showcase its functionality works against it and proves how flawed the device is.<\/span><\/p>\n

For starters, the oil filter isn\u2019t empty like the bottle on the inside. It\u2019s packed with filter elements and valves that prevent the oil from reverse flowing. This means the oil isn\u2019t free-flowing on the inside like it was in the bottle. Furthermore, as mentioned before, the metal particles will be caught in the filter elements and will not be dislodged.<\/span><\/p>\n

Conclusion<\/span><\/h2>\n

In conclusion, these oil filter magnets are mostly snake oil. If they really did function, carmakers would seriously look into installing them from the factory but we\u2019ve yet to hear a single one of them speak of it.<\/span><\/p>\n

If you truly are concerned about contaminants in the oil and improving the longevity of your engine, the best way is to follow the recommended oil change interval by the carmaker and use genuine, original lubricants that comprise the right oil filter and <\/span>engine oil<\/span><\/a><\/span>.<\/span><\/p>\n

Lastly, for the non-believers, if your foreman does find metal particles in your old engine oil, you\u2019ll need to ask why are they there to begin with. If there are metal particles in your engine oil, you will most likely have bigger problems regarding your engine that might even require an <\/span>overhaul<\/span><\/a><\/span>.<\/span><\/p>\n

And trust\u2026 no amount of magnets in the world will fix that.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
