<human>: How do you change the oil in a car?
<bot>: To change the oil in a car, start by locating the oil pan. It should be located near the bottom of your engine and is usually marked with a symbol such as an oil pan or a number 1. Next, locate the oil drain plug. This can be found on the side of the oil pan and may have a cap over it to prevent oil from draining out while the car is running. Once the oil drain plug has been removed, use a catch basin or container to collect the oil that drains out of the engine. Then, pour new oil into the oil pan until it's full. Make sure to check the level of the oil before pouring more in. Finally, replace the oil drain plug and then start your car to allow the oil to circulate through the engine again.
