The diesel engine oil filter mainly filters the oil in the engine lubrication system, removing mechanical impurities and gums to ensure the cleanliness of the oil.
Modern diesel engines generally use a disposable integral oil filter, which is connected in series between the oil pump and the main oil duct of the lubrication system, and is a full flow filter. The paper filter element is integrated with the shell and cannot be disassembled. Although diesel filters are small components on diesel engines, if they are not properly maintained, malfunctions during driving can also bring unnecessary trouble. Therefore, the correct use and maintenance of diesel engine oil filters and maintaining their normal working condition are crucial for extending the engine's service life.

1. Choose the appropriate model of oil
Choosing the appropriate type of oil plays an important role in the normal operation of the oil filter. The selection of engine oil model has multiple factors to consider. According to different temperatures, engine oil is divided into winter oil and summer oil; According to the different types of engines, engine oil can be divided into diesel engine oil and gasoline engine oil; Some engines also use specialized engine oil for lubrication. Therefore, it is important to be cautious in selecting the engine oil model to avoid situations where the engine oil filter may fail due to incorrect engine oil model.

2. Change the engine oil in a timely manner during seasonal changes
If the engine of a diesel engine uses oil that is not commonly used in winter and summer, the oil and oil filter should be replaced in a timely manner during seasonal changes to ensure the normal operation of the diesel engine.

3. Avoid working for long periods in harsh environments
When diesel engines operate in harsh environments, it is inevitable that various impurities will be mixed in the oil or the oil will produce a large amount of gum due to severe oxidation. Over time, the oil filter element used for filtering impurities will be blocked, causing the oil filter to fail. Therefore, maintaining a good working environment for diesel engines is also an important factor in extending the service life of oil filters.

4. Pay timely attention to the oil pressure situation
Observing the oil pressure displayed on the oil pressure gauge inside the diesel engine cab is also an important reference indicator for determining whether the oil filter can function properly. If the oil pressure is too low, it may be due to the failure of the bypass valve of the oil filter, causing the oil to enter the lubricating oil circuit directly without passing through the filter element for lubrication of important components of the engine. If the oil pressure is too high, it may be due to the blockage of the oil filter element, which also does not have the expected filtering effect on the oil. Therefore, it is necessary to promptly check the oil filter for abnormal oil pressure.

5. Develop good driving habits
Good driving habits are also an important means to extend the service life of oil filters. Improper operations such as forcefully pressing the accelerator and sudden braking by the driver may cause an increase in mechanical impurities in the engine oil. In addition, long-term overload and high-speed operation of the engine can also cause premature oxidation and deterioration of the oil, resulting in a large amount of gum. The increase in mechanical impurities and gum can lead to premature saturation and failure of the oil filter filtration capacity. Therefore, developing good driving habits can prevent the occurrence of oil filter failure.
