Foreword

I wrote an article about the purchase of oil last week. Thank you for your support for all the friends. The first time I wrote an original article to get a warm response from everyone, it made me a little flattered. It seems that it is worth buying. In terms of car maintenance.

I noticed that there are valuable friends mentioning the problem of the purchase of oil filter in the reply. From this I also thought that many riders attached great importance to the choice of oil, but often ignored the importance of machine filtering, such as the day The maintenance suggestion of Korean cars is 5,000 kilometers per time, but because the full synthetic motor oil has been extended, the maintenance interval has been lengthened to 10,000 kilometers, and the original machine filter is not so suitable. So I decided to write another article about how to buy articles.

Popular science: What is the oil filter?

The oil filter, as the name suggests, is used to filter the oil. During the operation of the engine, the oil will continue to become dirty. The source of pollution is mainly from: first, the dust, water and other foreign impurities entering the air intake of the engine; the other is the metal dandruff generated by the cylinder wear; the third is the various types of oil oxidation produced by the oil oxidation. Organic acids, focus asphalt, carbides, and so on. These impurities will deteriorate the lubrication effect of motor oil, produce mud, and even cause engine wear. The role of the oil filter is to filter out these harmful impurities and allow the oil to maintain good lubrication performance in the working life. Simply put, machine filter is equivalent to the kidney of a car. Isn’t it important to say weight?

A ideal oil filter should have the following characteristics:

1. Large traffic, small resistance, and meet the needs of the engine oil on the engine;

2. The filtering accuracy and filtration efficiency are high. In short, it is to filter the impurities particles of various sizes as much as possible;

3. Life is long, and the life span is more than 5,000 kilometers.

However, in fact, these three performance indicators often restrict each other. If the resistance rises when the flow is large; the high filtration efficiency is often accompanied by the rapid rise in resistance and short service life. Therefore, the characteristics of actual products can only be based on demand. Treating.

Which long -acting machine filter is worth buying?

Here are some brands that are easy to buy by mainstream domestic e -commerce companies. The following cards are not necessarily suitable for your car. You can consult e -commerce to confirm that you can buy it before you avoid trouble.

domestic

Mann Manpai W610/6 Machine Oil Filter

Manpai belongs to the German Manhomar Group, and is the world’s number one machine filter brand in the world. Mando filters sold in China are divided into two types: imports and domestic. The materials, workmanship and performance of imported Man are obviously better, but the price is much more expensive.

——The segmentation line of high -end filter–

Here are some higher -end unpopular import machine filters. The common features of these high -end machine filtering are: the filter element uses higher -level synthetic fiber materials, the filtering accuracy and efficiency are higher, and the indicators of pollution capacity are higher. It generally reaches 15,000 miles.

American K & N silver medal high -performance car oil filter

K & N is a competitive machine filter brand. There are two series of PS and HP series. The PS series focuses on high -traffic design, which can make the engine have better performance. The machine filter is almost the same.

Generally speaking, in addition to the square grades XG and K & N PS, these high -end machine filtrations are very expensive. Because domestic riders have rarely exceeded 10,000 kilometers, from the perspective of cost -effectiveness, individuals are not very recommended to buy vegetable cars. Use, high requirements for machine filtration performance, riders with a oil exchange cycle of more than 10,000 kilometers can consider buying.

Where should the machine filter buy it?

1. First choice

JD.com

The category is complete, and the mainstream models recommended above are basically available, covering the vast number of models. The price is very cheap, and there will be a 199-100/299-150 activity of the car accessories every 1 or 2 months. The filter is usually the original price to participate in the promotion. The amount of 2 or three years can be paid to, and the needy riders can usually pay more attention to the type of car category that is worth buying.

2,

Suning Online Market

Do not catch up with JD promotion and rush to filter with machines. You can buy it in Suning. There are often 2 20 % discounts, 3 40 % off such activities, and the price is also good.

3. Unpopular high -end filter can only find universal ones

Taobao

Some of the well -known Taobao stores selling imported oil and machine filtration are still more reliable. The boss usually understands it. When the model is not allowed, you can consult customer service more.

The correct installation method of machine filter:

Generally, riders to change the oil by themselves, they all go to local auto repair shops. The problem is that many small workers in auto repair shops have not undergone professional training. Many installed filters are screwed into death. It is light to damage the rubber sealing ring of the filter, which causes oil leakage. If it is severely damaged, the screw of the thread is filtered, and even the next maintenance is difficult to remove the machine.

The correct installation steps should be:

1. Check whether the appearance of the filter is damaged, especially whether the shell and sealing ring are damaged.

2. Apply a new oil on the sealing circle.

3. Rotate the machine to the machine filter sealing ring with the hand to contact the seat (that is, when it is twisted to start hard).

4. Turn it with a wrench for 3/4 laps.

5. After installing the filter and oil, the ignition empty gear steps on the throttle to allow the engine to run for about 1 minute. Observe whether there is any oil leakage.

In order to think of the safety of the car, the riders still have to stare at the small work of the auto repair shop. If necessary, you must guide yourself. Don’t be afraid to pull your face.

Conclusion

As the saying goes: “Good horses should be equipped with a good saddle”. I hope that while caring carefully selects the oil, do not ignore the importance of machine filtering. Choose a good machine filter to give full play to the performance of the oil and let your engine get your engine to get your engine getting your engine. The best protection.
