Never add a magnet to the machine filter, the consequences of adding a magnet to the oil filter

Oil filter element plus magnet? Many car owners may not know the purpose of this approach. It is said that this can absorb the metal iron filings inside when the oil is circulated to the oil filter, reduce the coefficient of friction inside the engine, and greatly improve the efficiency of the oil, thereby protecting the engine. However, car owners also have relatively big differences in this view, and there is no experiment to prove the effect of the oil filter element and the magnet.

The oil filter element and the magnet have serious consequences, and even affect the operation of the sensor

A large part of car owners agree that the machine filter does not need to add magnets, even if it is added, it is not very useful. There are even some car owners who reported that their car’s oil filter element has been added with a magnet to turn on the engine malfunction light, which is likely to be the magnet affecting the normal operation of the sensor.

With current engine technology, do car owners still need to use this method to improve performance?

In the past, the engine was cast iron. Today's engine has been developed to an all-aluminum engine. If a magnet is added to the oil filter, it seems to be a waste of effort. This is also the view of many car owners.

This point of view must be corrected here. Although the current engine is basically an all-aluminum engine, only the cylinder block and cylinder head are all-aluminum, and many parts are still made of cast iron. Car owners add magnets through the machine filter, theoretically there will be a little effect, but don't expect it to play a key role, regular oil maintenance is the most practical.
