How to change engine oil correctly?

How to change the oil yourself?
The steps for changing the oil are as follows:
1. Start the car engine and turn it off when the water temperature reaches the normal range. This is to allow the oil to flow fully in the engine, thereby taking away the impurities inside.
2. Lift the vehicle with a car lift. If there is no lift, you can use a jack instead, but it is not so convenient when operating.
3. Use the on-board tools to unscrew the bolts of the oil pan, and use a special wrench to open the oil filter to let the oil flow out. Since the flow rate of the oil port is very slow, you can open the filter at this time for secondary release.
4. After the oil has all flowed out, use a wrench to install the new oil filter, and pour the oil that meets the specifications (appropriate amount) into the oil pan. Note that the oil level must not exceed the maximum scale line (MAX).
