Mothers with busy schedules often encounter the challenges of stepping out of the house to complete errands while taking care of their children. It’s a common scenario that once you manage to leave your home and start your journey, your child invariably ends up falling asleep.
Upon arriving at your destination, you might find yourself pondering the duration for which you can keep your vehicle idling safely while parked, allowing you to quickly dash out and complete an errand without causing any disruptions to the surroundings.
Typically, letting your car idle for more than five minutes can lead to the engine exceeding its normal operating temperature. In several states, idle time is restricted to 20 minutes during cold weather conditions. If you find it necessary to idle your vehicle, consider taking a short drive around the block every five minutes to mitigate this issue.
Hybrid or electric vehicles are exempt from this concern, as they utilize electric motors for idling instead of relying on gasoline engines.
From a technical perspective, it is feasible to keep your car running for several hours until you exhaust the fuel supply, but this doesn’t imply that you should do so. This article will delve into the reasons why this practice is discouraged, the situations in which it is acceptable to leave your car idling, and strategies to minimize idling whenever feasible.
What Is Idling Anyway?
Idling entails operating a vehicle’s engine at reduced power when the vehicle is stationary and not in motion. It occurs when the engine is running while the car remains stationary.
When Is It Okay To Leave My Car Running?
There are situations where idling becomes unavoidable. For instance, when you’re caught in traffic, waiting at a stoplight, or queuing up in the school pick-up line, your car is likely to be running. Perhaps you need to heat up the car’s engine and interior during a chilly morning. In such instances, it may be more practical to keep the vehicle running for a brief duration.
Similarly, the scenario of the busy mother we discussed earlier might find it acceptable to briefly leave the car running while making a quick stop at the ATM or running into the UPS store to drop off a package. However, for any task that extends beyond a brief errand, it is advisable to turn off the engine.
When you find yourself needing to leave your young child in the car briefly on a hot day, it’s crucial to ensure their comfort and safety. If you prefer not to use the air conditioning at maximum, consider parking in a shaded area and rolling down the windows if possible.

Why Should I Avoid Idling?
Whenever feasible, it’s wise to minimize extended periods of idling and be conscious of when and how frequently you engage in this practice. Here are several reasons why you should reconsider leaving your car running:
It Wastes Fuel
There is a widespread misconception that turning off and restarting your engine consumes more gasoline than idling. Information provided by the Environmental Defense Fund highlights that stopping and restarting your vehicle actually consumes an equivalent amount of fuel as idling for just ten seconds.
Modern fuel injection technology has alleviated concerns about fuel wastage when drivers stop and restart their vehicles. If you come to a halt for more than a minute, it’s more fuel-efficient to switch off your engine. Given today’s high gas prices, restarting your engine is unquestionably the more economical choice.
It Can Be Hard On Your Engine
Prolonged idling can have detrimental effects on various components of your engine, such as the exhaust systems, cylinders, and spark plugs. This is primarily due to the fact that when your vehicle is idling, the fuel undergoes incomplete combustion.
Consequently, this incomplete combustion can result in the accumulation of deposits on the cylinder walls, which can then lead to harm to both spark plugs and exhaust systems.
Itās Harmful To The Environment
Carbon dioxide (CO2) stands as the primary contributor to global warming, and it is discharged into the atmosphere through car emissions during idling. Therefore, for every ten minutes that your engine remains off, you’ll prevent the release of one pound of carbon dioxide, contributing to environmental conservation.
Hence, if you’re concerned about the air quality that your family is exposed to, it’s advisable to minimize the duration for which your car remains running.
Itās Harmful To You And Your Familyās Health
As appealing as it might seem to keep the car running while you quickly enter a store or a bank, it may not be the healthiest choice for your child. Are you aware that during idling, exhaust fumes can infiltrate through the vehicle’s vents?
Prolonged exposure to excessive carbon monoxide (CO) can elevate the risk of developing or exacerbating hazardous conditions for both you and your family. These conditions include asthma and allergies. Furthermore, it can heighten the likelihood of heart and lung diseases, cardiopulmonary ailments, and even certain forms of cancer.
You May Run Out Of Gas
If your fuel tank is running low, it’s wise to reconsider extended periods of idling, as this could potentially deplete your fuel reserve. Running out of gas on your way to school pickup is the last thing you’d want to experience.

It Could Be Illegal
Several U.S. states, including New York, Massachusetts, Hawaii, and certain regions of California, have enacted legislation that renders idling unlawful. Other nations have also adopted similar measures. Engaging in unnecessary idling can lead to fines, so it’s advisable to turn off your engine when uncertain about the necessity to keep it running.
Are There Times I Shouldnāt Leave My Car Running?
Leaving your vehicle running while refueling at a gas station is an action to avoid entirely. The fumes emitted by gas pumps can readily ignite due to their elevated temperatures. Therefore, it’s imperative to ensure that you completely turn off your engine when refilling your tank.
Leaving your car idling in the garage is likewise an unsafe practice, particularly when the garage door is closed or if there are family members inside the vehicle. This can result in the ingress of hazardous levels of carbon dioxide, posing the risk of poisoning or, in severe cases, fatality.
Whatās The Deal With Hybrid Or Electric Vehicles?
Owners of clean air vehicles, such as hybrids or electric cars, can take comfort in some positive news. They need not be as concerned about the adverse effects of idling.
In hybrid vehicles, when idling occurs, the gasoline engine shuts off, and power shifts to the electric motor, resulting in a reduction in both emissions and fuel consumption. On the other hand, electric vehicles (EVs) solely rely on electricity for operation, resulting in zero emissions and exclusive utilization of the electric motor.
Given that hybrids and electric vehicles operate more quietly when their engines are engaged compared to traditional vehicles, it’s important to remember to turn off the engine to prevent battery drain when idling.
Common Misconceptions About Car Idling
Over the course of time, you’ve likely encountered numerous misconceptions regarding idling. In the following sections, we will debunk some of these prevalent myths and offer guidance on how to minimize the tendency to idle excessively.
You Need Your AC Or Heater When Parked
Rather than idling your vehicle while running the air conditioning or heater, contemplate bringing items such as a hat, gloves, and a hot beverage for chilly days or a personal fan for warm days. If the external temperature is cooler than the interior of your car, it’s advisable to turn off the engine and roll down the windows to enjoy a refreshing breeze.
You Need To Warm Up Your Engine In The Morning
Numerous individuals residing in cold-climate regions might not be aware that there’s no need to extensively “warm up” their engine and interior. Simply turning on your car for around 30 seconds before commencing your journey is typically sufficient for modern vehicles, and the vehicle’s interior will further warm up as you begin driving.
As an additional option, contemplate taking a short drive around the neighborhood to facilitate warming up your car instead of allowing it to idle unnecessarily.

The Impact on Fuel Efficiency
Understanding the relationship between idling and fuel efficiency is crucial for responsible vehicle ownership. Idling significantly affects fuel consumption, and unnecessary idling can result in substantial fuel wastage over time. This section delves into how idling influences fuel efficiency and provides insights into the cost savings and improved vehicle efficiency associated with reducing idling.
How Idling Affects Fuel Consumption
When your vehicle’s engine is running, it consumes fuel to maintain the engine’s idle speed. However, during idling, your vehicle covers no distance, meaning that fuel is being consumed without any mileage gain. In essence, idling provides zero miles per gallon (MPG). The fuel injection system continues to supply a small amount of fuel to keep the engine running smoothly, which adds up over time.
Estimates of Fuel Wasted Due to Unnecessary Idling
The amount of fuel wasted due to idling can vary based on several factors, including the engine’s size, efficiency, and the duration of idling. On average, it is estimated that idling consumes about 0.2 to 0.5 gallons of fuel per hour for a typical passenger vehicle. For larger vehicles with larger engines, such as trucks and buses, the fuel consumption during idling can be considerably higher.
Let’s consider an example to put this into perspective. If you leave your car idling for 10 minutes each day while waiting at drive-throughs or while parked, it can result in wasting approximately 0.03 to 0.08 gallons of fuel per day. Over a year, this seemingly small idling habit can add up to around 11 to 30 gallons of fuel wasted. Multiply this by the number of vehicles on the road, and the environmental and economic impact becomes significant.
Cost Savings Over Time
Reducing idling translates to cost savings. If you reduce your idling time by just 10 minutes per day, you could save around 3.65 to 10 gallons of fuel annually, depending on your vehicle’s fuel consumption. With fluctuating fuel prices, these savings can amount to a considerable sum over the years.
Improved Overall Vehicle Efficiency
Minimizing idling not only saves money but also contributes to improved vehicle efficiency. When your engine is not idling unnecessarily, it runs more efficiently when you need it, resulting in better overall fuel efficiency. This efficiency improvement can extend the lifespan of your vehicle and reduce maintenance costs, further enhancing your financial savings.
In summary, idling is a significant factor affecting fuel efficiency. By understanding the impact of idling on fuel consumption and recognizing the costs associated with unnecessary idling, vehicle owners can take steps to reduce idling time. This not only leads to immediate cost savings but also contributes to a cleaner environment and better vehicle efficiency, ultimately benefiting both the individual and the community as a whole.
Final Thoughts
Although there are situations where idling is unavoidable, it’s prudent to be mindful of the duration and frequency with which we casually leave our cars running. Indeed, the repercussions could be more substantial than we might initially perceive.
The next instance you encounter a wait in the school pickup line or while at the drive-through coffee window, contemplate the option of turning off your engine rather than letting the car run. This not only alleviates financial burdens but also contributes to your family’s well-being, the planet’s health, and the longevity of your vehicle.
