What are the steps for changing engine oil?

[MacCamille]

Steps for changing engine oil: 1. Lift the car, remove the undercover, and place a container of about 10 liters under the oil drain plug; 2. Unscrew 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 car, use a funnel to add oil at the oil filler port. Precautions for changing engine oil: 1. Perform the procedure when the engine is warm to ensure the old oil is drained as completely as possible; 2. Add oil and ensure the amount is appropriate; 3. After adding oil, start the engine and check for any leaks. Run the engine for 3 minutes to confirm the oil level is at the normal mark.
