Where is the oil drained from the engine on 91 stanza?

On a 1991 Nissan Stanza, the oil is drained from the engine via the oil pan's drain plug, which is located at the bottom of the oil pan. To drain the oil, you typically remove the drain plug using a socket wrench, allowing the old oil to flow out into a suitable container. It's important to ensure the engine is warm for better oil flow but not so hot that it causes burns. Always replace the drain plug securely after draining the oil.
