<human>:  How do you change the oil in a car?
<bot>: To change the oil in a car, first you will need to locate the oil plug and unscrew it to drain the old oil. Once the oil has been drained, screw the oil plug back in and add the required amount of new oil. Make sure to use the correct grade of oil for your car's make and model and check that there are no oil leaks afterwards.
