Is magnet magnetizing oil good? How about magnetic guard oil, what kind of car can generally be used

Not good, the method is not scientific, it will cause damage to the engine.

The magnetic field generated by a permanent magnet is a magnetic field that does not change in strength, and this magnetic field has no magnetizing effect on non-magnetic substances at all.

If it is a magnet of varying intensity, an oscillating magnetic field is generated. Then it's a different story. In this case, it is not the magnetization of the magnet that is at work (the material affected by the magnetic field does not change the magnetic properties), but this oscillation mode is at work.

There is a similar phenomenon that may help to understand:

Electric current cannot pass through an insulator, and direct current cannot "leap" from one conductor through the air to another conductor (breakdown is another phenomenon). However, alternating current can pass through the capacitor smoothly.

No, it's wrong!! Iron filings are magnetized, which can adhere to the parts and exacerbate wear!!

Some people say that putting magnets in oil filters is not a new thing for a long time to extend the life of the engine, and some people say that it is an IQ tax. Does it work? Let's talk about this today.

1. Will the engine produce iron filings? It must be known that many cars nowadays are all-aluminum engines, but the key internal friction parts are steel. For example, the piston is aluminum, while the cylinder wall is steel.

Moreover, the piston is not in direct contact with the cylinder wall. What really comes into contact with the cylinder wall are the piston rings that are stuck on the piston, they are made of steel. There are also engine camshafts, timing chains, crankshafts, and various gears and bearings.

Almost all of the friction in the engine is steel, so it's not surprising that iron filings are generated. 2. Are iron filings harmful to the engine? Iron filings from normal wear and tear have little effect on the engine, but have a very large impact on the psychology of the owner.

First, there is the question of quantity. We know that the coordination inside the engine is very delicate. If the iron filings wear out quickly, I don't think the car is scrapped.

The engine brushes itself first. In fact, the wear and tear on the inside of the engine is much lighter than we thought. For example, important friction surfaces such as cylinder walls, skirts, bearings, camshafts, etc., are coated with wear-resistant coatings.

In other words, when the engine is running, only the wear-resistant coating is at work in most places, and there is an oil film in the middle, but the real production of iron filings is the relatively unimportant timing chain, various sprockets, and gears. The second is the problem of the size of the iron filings. To put it simply, large particles of iron filings may have a negative effect on the engine, but this iron filings will definitely be filtered by the oil filter.

Iron filings that cannot be filtered by the machine do not have to worry about damaging the engine. 3. Does it help to put a dry mountain magnet in the oil filter? First of all, put a magnet in the filter of the machine to suck out the iron filings in the oil.

However, this is a very small amount. I used to use a saw to see through an old oil filter that sucked magnets from the outside, and there weren't as many iron filings in it as we thought. A lot of iron filings on the Internet are almost all deliberately smoked by sellers in order to improve the publicity effect.

Secondly, adding magnets to the machine filter can attract iron filings, but this does not necessarily reduce the wear and tear of the engine. Even if the magnet is not adsorbed in the matter, the filter paper is filtering, and if the iron filings are small enough to pass through the filter paper, it will be difficult to cause any harm to the engine, so there is no need to worry. Therefore, adding magnets to the filter does little to protect the engine and prolong the life of the engine.

The easiest way to extend the life of the engine is to change the engine oil frequently and add qualified gasoline. Because the engine of a private car is designed with most of the problems that may arise in use. That is to say, it is difficult for you to use it normally, but it is up to the owner to change the oil and refuel, which is more likely to cause problems.

Magnetic oil is suitable for all models, but the replacement time or mileage is relatively short, therefore, if you drive a long-distance car or often drive a car for a long time, it is not suitable, the oil change cycle is relatively short, and the frequency of maintenance and replacement is relatively high. If you don't usually drive long distances, or usually only drive on city roads, it is more suitable to add magnetic protection oil.

Since the magnetic oil is a semi-synthetic oil, under normal circumstances, the car needs to be maintained after driving 7000km or 8000km, or it needs to be replaced in time after about 9 months.

Although magnetic protection oil is suitable for all models, the replacement time or mileage is relatively short, so if you drive a long-distance car or often drive a car for a long time, it is not suitable, the oil change cycle is relatively short, and the frequency of maintenance and replacement is relatively high. If you don't usually need to drive long distances, or usually only drive on city roads, it is more suitable to add magnetic engine oil.

There are basically five types of magnetic oil filters or magnetization devices on the market today:

1. Stir-fry the concept.

This kind of oil filter can not see the existence of magnetic products at all, whether it is external or internal, and it can not detect magnetism, it is a false name added to the existing ordinary oil filter, which is to sell ** and deceive consumers.

2. Install a magnetization device with a shielding layer on the existing ordinary oil filter housing.

This magnetization device is to adopt a fixed structure or use the magnet's own magnetic force to adsorb on the existing filter shell after the magnet is matched with a shielding material, and is used to adsorb the ferromagnetic impurities in the oil in the filter, the idea is good, but in the actual use of this kind of device, because most of the magnetic field is shielded by the oil filter shell, the magnetic field utilization efficiency is extremely low, and basically does not work; In addition, when the vehicle is driving on a bumpy road, it is easy to cause oil leakage or falling off the filter, which will cause immeasurable damage to the vehicle.

3. Directly adsorb one or several magnets on the surface of the existing ordinary oil filter housing.

This kind of magnet is directly attached to the existing oil filter housing, whether it is pasted on the side of the oil filter or the bottom of the oil filter, not only does not play a filtering role, but also interferes with the normal operation of other electronic equipment on the vehicle, which is extremely dangerous and has serious consequences.

4. Set the magnet on the bypass valve housing.

Because the filter is in normal operation, the bypass valve is in a closed state, and the oil is circulated back to the engine through the paper filter element, and the main oil flow can rarely touch the position of the bypass valve in this state, so the magnet is set on the bypass valve shell not only has a small effect on the filtration of ferromagnetic impurities, but also causes the bypass valve to fail, so that the circulating oil flows directly back to the engine through the bypass valve, so that the non-ferromagnetic impurities can not be effectively filtered by the paper filter element, or the bypass valve is blocked, and the paper filter element is suffocated.

5. Daji brand strong magnetic oil filter.

Daji strong magnetic oil filter is to set the strong magnetic filter element in the central pipe near the end of the oil outlet of the filter, and the invention has the following design features and advantages:

The shell and central tube of the filter are used to replace the magnetic field shielding layer, and the strong magnetic field outside the filter shell is double-shielded to avoid the leakage of the strong magnetic field of the strong magnetic filter element and interfere with other equipment;

It can make the strong magnetic filter element fully contact with the oil, and the magnetic field utilization rate is 100%;

The strong magnetic filter element is set in the central pipe near the end of the oil outlet, which is the most spacious place in the filter, the strong magnetic filter element will not produce resistance to the oil circulation, even if the impurities adsorbed on the strong magnetic filter element will not have a little impact on the oil circulation, and it is also far away from the bypass valve, avoiding the influence of the strong magnetic field on the bypass valve, and here is the only way for the oil and impurities, which can filter out all the impurities flowing through the filter to the greatest extent;

After testing, the impurity filtration effect of Daji brand strong magnetic oil filter has been achieved. It can increase the impurity filtration rate of existing oil filters by up to 60%.

To be honest, if you want to identify the quality of a motor oil from the appearance, according to the development of today's science and technology, it is really difficult, whether it is packaging, anti-counterfeiting logo, or font, the workmanship is so seamless.

But this oil can really distinguish some good from bad, and for some reason, there are only two kinds to name here:

Identification before opening the bottle.

Generally, the sound of the oil is very loud and brittle, just like the sound of a bottle of mineral water shaking. And a good engine oil is sticky, and the sound of shaking will be very different. When buying, you can shake each other to compare, this is actually the simplest, most direct, and best way to use.

Some oils with good viscosity and good color are not necessarily good oils.

This is to open the lid to see, after adding the oil, and then see if there is a black precipitate at the bottom of the bottle, if there is, then the disturbing omen congratulations you have won the lottery, this must be refined from waste engine oil. Some good used engine oil is re-filtered and then turned into new engine oil. And if this oil is identified by shaking, it is really not good, because its viscosity is still there, but it is a little lacking in color or temperature resistance and wear resistance.

Therefore, in order to achieve the purpose of profit, some people adopt the method of filtering to get by.

The last thing to say,It is only the best to buy engine oil in a regular store

Castrol magnetic protection engine oil is very good, basically all models can be used, the most reliable is of course to go to the local general Min Zhou ** business to buy, will not buy parallel goods, you can also go to the day to buy the cat Castrol official flagship bridge store.

I don't like magnetic engine oil very much, it's just a semi-synthetic engine oil, the quality is more average, go to the official to buy the quality fidelity, but **expensive. Or I use GT magic red engine oil, it is a base oil of four types with a letter to call PAO, high temperature resistance and recession resistance is very good, long-term maintenance, 15,000 kilometers of replacement cycle is worth the previous oil change twice, maintenance is a lot more cost-effective, and the brand is not fake, the official channel control is very good, use it with confidence.
