I'm looking to buy a new car. I need to know how to change the oil.

The first step is to locate the engine oil pan, usually located at the bottom of the engine near the transmission and transfer case. Then, use a socket wrench or ratchet to loosen the drain plug. Once loose, slowly turn the handle clockwise until you feel it start to spin. This will allow the oil to drain out. After all of the oil has been drained, replace the oil filter and tighten it with an appropriate torque wrench. Finally, add the recommended amount of new oil and replace the oil cap.
