The replacement cycle of the oil filter is generally 12,000 kilometers. Most cars use disposable filters that are not removable and washable.
When replacing the lubricating oil, the oil filter must be replaced at the same time, otherwise the quality of the lubricating oil will be affected.
Since the oil has to pass through the oil filter to reach the lubricating part, the function of the oil filter is to filter the impurities in the oil entering the engine system, so as to prevent the impurities (dust, metal chips and colloids formed by oxidation of oil) that are continuously mixed in the oil during the cycle of use, causing the oil passage to block and even damage the engine and other serious consequences.
From the perspective of maintenance, the oil and oil filter need to be replaced if the car has not been opened for a long time to ensure the good lubrication effect of the oil on the engine.

Why should the oil filter be changed regularly?
The function of the oil filter is to filter the fuel of the car.
Gasoline is refined from crude oil through a complex process, and then transported to various refueling stations through special channels, and finally delivered to the owner's fuel tank. In this process, impurities in gasoline will inevitably enter the fuel tank. In addition, with the prolongation of use time, the impurities will also increase. In this way, the filter used to filter the fuel will be dirty, and the filtering effect will be greatly reduced.

What happens if the oil filter is not changed regularly as required?
Lubricating oil (commonly known as engine oil) is stored in the oil sump. When the engine is running, the oil pump is driven, the oil is drawn out from the oil pool, passed through the oil filter, and then sent to the parts that need to be lubricated through the oil pipeline, such as crankshaft, camshaft, rocker arm, etc. Finally, the oil flows back to the sump. So back and forth, constantly working.
As far as the engine is concerned, the oil plays the functions of lubricating, cleaning, cooling, and sealing. Therefore, no matter what kind of car owners, they must change the oil according to the mileage specified in the manual.
If the engine oil is not replaced regularly or counterfeit engine oil is replaced as required, the engine will not work well, it will be difficult to start, or the piston ring will be stuck, causing serious engine wear.。
Therefore, the oil filter needs to be replaced after driving a certain number of kilometers. If it is not replaced, or it is delayed, it will affect the performance of the car, resulting in poor oil flow, lack of refueling, etc., and finally lead to chronic damage to the engine, or even overhaul of the engine.
How often should the oil filter be changed? The replacement cycle of the car oil filter is generally about 10,000 kilometers. For the best replacement time, please refer to the instructions in the vehicle manual. Usually, the replacement of the fuel filter is carried out when the car is undergoing major maintenance, and the air filter
Replace the oil filter at the same time.
