[Haley]

The method for changing engine oil without a lift is to find a pit, drive the car over it, and then go down into the pit to change the oil. The steps for changing the oil are: 1. Lift the car, remove the protective plate, and place a container of about 10 liters under the oil drain screw; 2. Unscrew the oil drain screw, use an air gun to blow for two minutes at the oil filler port, after draining the oil, tighten the oil drain screw and wipe it with a tissue to check for oil leaks; 3. Reinstall the protective plate and lower the car, then use a funnel to add oil at the oil filler port. The functions of engine oil are: 1. Lubricating the engine to reduce wear; 2. Cleaning and purifying; 3. Cooling and lowering temperature; 4. Preventing rust and corrosion.
