Is Engine Warm-up Necessary in Summer?

[Juan]

Engine warm-up is not necessary in summer, and here are the reasons: 1. Engine warm-up is not required in any season because idling to warm up the engine is ineffective for fuel-injected engines and only useful for carburetor engines. 2. However, carburetor engines have been phased out, and modern cars use fuel-injected engines, so warm-up is no longer needed. Idling to warm up the engine not only fails to quickly raise the engine temperature but also leads to increased carbon deposits inside the engine. Prolonged idling also increases fuel consumption. 3. The correct driving method is to start driving immediately after starting the engine, just avoid running the engine at excessively high RPMs during the initial driving period. This approach protects the engine and reduces wear.
