How much gas does a car burn per hour while idling?
Is it better to turn off the car if I know I'll be idling for a while?
It depends on the situation. If you know you'll be idling for more than 30 seconds, it's more fuel-efficient to turn off your engine. However, if you'll be moving again in less than 30 seconds, it's more efficient to keep it running.
