[DeEvangeline]

When changing engine oil, it is necessary to replace the oil filter. The method for changing engine oil is as follows: 1. Lift the vehicle, remove the undercover, and place a container beneath the oil drain plug; 2. Loosen the oil drain plug, use an air gun to blow for two minutes at the oil filler port, then tighten the oil drain plug after draining and wipe it with a tissue to check for leaks; 3. Reinstall the undercover and lower the vehicle, then add new oil through the filler port. Precautions for changing engine oil: 1. Perform the change when the engine is warm to ensure the old oil is thoroughly drained; 2. Add the new oil and ensure the amount is appropriate; 3. After adding the oil, start the engine and check all components for leaks. Run the engine for 3 minutes to confirm the oil level reaches the normal mark.
