<human>: How do you change the oil in a car?
<bot>: To change the oil in a car, start by locating the oil pan. Then use a socket wrench to loosen and remove the oil drain plug. Place a container under the oil pan and allow all of the oil to drain into it before replacing the drain plug. Next, use a funnel to add new oil to the engine until the oil level is at least one inch below the top edge of the oil pan. Finally, replace the oil filter and tighten the oil cap on the engine.
