Is Warm-Up Necessary in Summer?

[VanWalter]

Warm-up is not necessary in any season. Idling to warm up the engine is ineffective for fuel-injected engines and only useful for carbureted engines. However, carbureted engines have long been phased out, and no vehicles use them anymore. Therefore, warm-up is unnecessary in any season. More details about warm-up are as follows: 1. Point One: Idling to warm up the engine not only fails to raise its temperature quickly but also increases carbon buildup inside the engine. 2. Point Two: Prolonged idling to warm up also increases fuel consumption. 3. Point Three: The correct way to drive is to start moving after engaging the gear once the engine is started, but avoid driving at excessively high RPMs during the initial phase to protect the engine and reduce wear. 4. Point Four: Once the engine coolant reaches normal operating temperature, you can safely increase the RPMs.
