Should I Turn Off the Engine When Parking for Three to Four Minutes?

It is recommended to turn off the engine when parking for three to four minutes. Below are the relevant details about turning off the engine while parking: Reasons for turning off the engine when parking: Temporarily turning off the engine while parking is beneficial as it saves fuel and contributes to environmental protection. If the parking time exceeds 1 minute, the engine should be turned off. Generally, the fuel consumed by idling a small car is more than the fuel required for a restart. For automatic transmission vehicles, if the expected parking time exceeds 0.5 minutes and you do not wish to turn off the engine, shift the gear to N. If the parking time is longer, the engine should be turned off. Hazards of not turning off the engine while parking: Theoretically, turning off the engine after 3 minutes of parking does help in reducing air pollution, but implementation is challenging. The current difficulty in implementing the "turn off the engine after 3 minutes of parking" rule is due to two scenarios where people are reluctant to turn off the engine. One is during hot summer days when the air conditioning is needed for extended parking periods, such as unloading goods or waiting for someone. The other is at traffic lights, where drivers worry about slow engine restart and prefer not to turn off the engine.
Turning off the engine after parking for three to four minutes is definitely a good habit. Idling the engine wastes fuel and pollutes the air for no reason, and restarting modern cars won't harm the engine. I've developed this habit since I started driving, and the real benefits are fuel and cost savings. To put it into perspective, idling for an hour consumes about 1 liter of fuel, while parking for four to five minutes uses around 0.15 liters. Over a year, this adds up to significant fuel savings. From an environmental standpoint, reducing exhaust emissions helps improve urban air quality—small contributions can make a big difference over time. This is especially important during city traffic jams, where turning off the engine becomes even more crucial. Overall, it also helps maintain engine health and saves on repair costs, making this approach a win-win on multiple fronts.
I turn off the engine every time I park for three or four minutes. Experienced drivers say that idling causes faster carbon buildup in the engine, which affects performance over time and leads to costly repairs. Engine idling can also cause uneven temperatures, accelerating wear on components. I recommend developing the habit of automatically turning off the engine, even for brief stops. Additional benefits include avoiding noise disturbance and enjoying a quieter rest in the car. Maintaining your car extends its lifespan and saves you from future hassles. A related topic is that regular engine inspections can help identify potential issues early, allowing for preventive measures and timely fixes.
