Does a Car Consume Fuel When Started but Not Moving?

[CalvinRose]

Starting the car without moving does consume fuel. Here are the relevant details: 1. Prolonged idling can damage the engine: Although it consumes less fuel than driving, prolonged idling can harm the car's engine. 2. Prolonged idling can cause carbon buildup in the engine: Starting the car without moving means the engine is idling. Idling refers to the engine running without load, typically at 550-800 RPM. If the car idles for too long, it can lead to carbon buildup in the engine. 3. Idling speed should be controlled appropriately: Both high and low idle speeds are undesirable. A high idle speed can increase fuel consumption, raise the engine's internal temperature, accelerate engine wear, and reduce its lifespan. Conversely, prolonged low idle speed can cause the car to stall.
