The correct use of oil filters can effectively save engine maintenance costs, extend maintenance intervals to 20000 kilometers, and improve the engine's service life.

The daily inspection and maintenance of the lubrication system should pay attention to the following items:

1. Check for external oil leaks

2. Check the oil level and oil quality

3. Use Dongfeng Cummins designated engine oil and oil filter

4. Change the engine oil and oil filter in a timely manner during the maintenance cycle

In daily maintenance, the use of inappropriate or inferior oil and filters may cause wear and tear on internal parts of the engine, thereby reducing the service life of the engine and increasing maintenance costs.
