It is well known that the engine cannot run without lubrication system. We know that oil, as a lubricant, can not do without the help of oil filter. When it comes to car maintenance, the most basic thing we can think of is to change the oil filter. The filter looks very common, but it plays a vital role in the engine system.
Today, let's briefly talk about the "terrible" failures caused by improper use, installation or replacement of the machine filter element.

1. What happens if the oil filter is not changed?
The owner does not change the oil filter for a long time. In extreme cases, the engine oil filter that has been in service beyond the time limit will choose to give the owner a "lesson".
The machine filter has been used for a long time, and the filter material is seriously blocked. When the oil passes through the machine filter, it will become extremely smooth. At this time, the oil flow will decrease, the flow will decrease, and even the oil may be cut off for a short time. In this state, the engine will be difficult to start due to insufficient lubrication and high friction resistance of mechanical parts, which usually requires the driver to try many times before starting.
In extreme cases, under the dual effects of oil pressure and oil chemical composition, the internal filter material will deform and collapse structurally. In addition, some vehicle maintenance history shows that part of the filter material in the filter has been dissolved by engine oil because the filter has not been replaced for a long time. Changes in the structure or shape of the above oil filter are likely to cause an oil pressure alarm on the engine dashboard.

2. Malfunction caused by improper installation of machine filter
During the construction process of replacing the oil filter, the oil in the car will be released and it is not easy to collect, so the car owner will generally choose to go to the service provider (check the transaction price | participation | preferential policy) for such maintenance. However, even if you go to an auto after-sales service agency for service, you need to pay attention when installing new parts.

3. What happens if the oil filter is broken?
Owners want to reduce the cost of car maintenance, and car service providers also want to reduce operating costs. These requirements give the branch components and counterfeit products room to survive. These irregular parts have also brought a lot of trouble to car owners and car service practitioners.
The products or counterfeit products of affiliated factories without quality assurance are very different from the genuine ones. On the one hand, the non-genuine machine filter, the filter material arrangement structure is loose, the filter hole diameter of the filter material itself is large, and the filtering effect is poor. On the other hand, most non-genuine machine filters are not equipped with bypass valves. Even if there is a bypass valve, its function is very limited. If the bypass valve is missing or working poorly, the oil circulation will be seriously blocked after the filter material is blocked, resulting in engine damage due to insufficient lubrication.
In addition, the sealing of the oil seal of the machine filter in the auxiliary building was not guaranteed, resulting in oil leakage at the connection between the machine filter and the machine filter base. The above problems are common "side effects" of mechanical filter in auxiliary equipment plant.
Compared with the wear that is not easy to be detected, the sensory stimulation of the vehicle owner is obviously stronger due to the difficulty of starting the vehicle, the oil pressure alarm and the leakage of the filter position. I hope that car owners can enjoy high-quality travel life instead of being frightened by frequent car failures. The correct selection and use of mechanical filter is very important for everyone's daily use.
