Human: I'm looking to buy a new car. I need to know how to change the oil. Assistant: 
To change the oil in your car, you will first need to locate the oil pan underneath the engine. Once you have located it, use a socket wrench to loosen the drain plug and allow the oil to drain completely. Next, place an oil filter onto the end of the oil pump and install the oil filter gasket. Then, fill the engine with the recommended amount of oil. Finally, replace the oil drain plug and tighten it securely.
