<human>:  How do I change the oil in my car?
<bot>: The first step is to warm up your engine by turning it on and allowing it to idle for a few minutes. Then, raise your car using a jack and secure it with jack stands. Next, locate the oil drain plug under the car, remove the plug and drain out the oil into a catch basin or oil pan. After the oil has drained, replace the oil filter and then screw the drain plug back onto the oil pan. Finally, add the recommended amount of new oil and replace the oil cap.
