Should the Car Be Warmed Up Before an Oil Change?

[EmilianoMarie]

It is necessary to warm up the car before changing the oil, typically for about 5 minutes. Below are the benefits of warming up the car before an oil change: 1. Engine oil is a liquid with a certain viscosity. If the temperature is low, the viscosity will be higher, making it difficult for the oil to flow out when the oil pan drain plug is removed. 2. There may be sludge inside the engine, which will soften after warming up, allowing it to be flushed out with the old oil. 3. It will be easier to remove the oil filter after warming up the car. When changing the oil, the oil filter should also be replaced. The area around the oil filter is often covered with oil and sludge, making it difficult to remove when the engine is cold. Additional note: When changing the oil, ensure all the old oil is completely drained before adding new oil. Otherwise, the old oil may contaminate the new oil, reducing its lubrication effectiveness and performance.
