Is it necessary to warm up the car after an oil change?

[JosephineMarie]

It is not necessary to warm up the car after an oil change, but warming up the car is required before changing the oil. Engine oil is often referred to as the lifeblood of an engine. Inside the engine, oil not only serves as a lubricant but also performs functions such as cleaning, sealing, cushioning, rust prevention, and heat dissipation. During normal engine operation, the oil forms a protective film on the surfaces of various engine components. This film reduces friction between parts and minimizes operational resistance. Without oil, the engine cannot function properly. Regular oil changes are essential because prolonged use degrades the oil's lubricating properties, which can accelerate engine wear.
