It is generally recommended to change engine oil when it is warm, but not excessively hot. Warm oil flows more easily, allowing it to drain out more completely and carrying away more contaminants. When the oil is too hot, there’s a risk of burns and it may drain too quickly, potentially leaving some dirty oil behind. However, if the oil is cold, it becomes thicker and more viscous, making it harder to drain efficiently. Therefore, the optimal temperature range for changing oil is when the engine has been running for a short period, enough to warm the oil slightly above ambient temperature but not hot enough to cause burns. This ensures thorough drainage and better effectiveness of the oil change process.
