Car Idling: How Long Can Your Car Idle?

Your car is said to be idle when the engine is working without causing any movement to it. Idling usually happens when you’re waiting while parked outside a business or residence, when you stop at a red light, or otherwise stationary with the engine running. You can let your car idle indefinitely as long as there is fuel in it. However, this is not recommended because it can heat the engine and the thermostat or the fan belt can eventually break and damage your car.
