Should You Warm Up Your Car in Winter?
The weather outside is frightful—and so are the ideas about warming up your car in winter. And when you turn to the internet for sound advice on whether or not you should warm up your car during winter, most of the time, you’ll probably get mixed results. For sure, the internet is full of advice on when, how long, and how much fuel should be burned warming up your car before you drive it. But we’ve taken a closer look at this practice, from all angles, and found that there are actually only two times when you might want to warm up your vehicle:
1) if it’s been sitting outside for an extended period of time (say overnight), or
2) if you live in a very cold climate where temperatures drop below zero degrees Fahrenheit for weeks on end. Other than that? Skip it!
The Benefits of a Warm Engine
1. Cold Starts vs. Warm Engines
One thing is clear—engines love warmth! They perform optimally when they reach their designated operating temperatures. When you glance at your temperature gauge, aim for the needle to sit snugly between the “C” for cold and the “H” for hot. However, here’s a crucial point to remember: engines warm up far more efficiently when they’re actually in motion, not idling in your driveway. So, if you’re a proud owner of a hybrid vehicle, consider warming it up while it’s still connected to the grid power for an eco-conscious start to your journey.
2. The Cost of Idling
Let’s talk money. Warming up your car for extended periods on frosty mornings can drain your wallet faster than you might think. Consumer Reports conducted a study that revealed idling your car for 30 minutes in 20-degree weather could cost you a significant $1.00 per hour. If you’re a daily commuter or frequently hit the road, these costs can add up. Additionally, excessive idling releases harmful carbon monoxide into the environment, which poses risks, particularly when children are around. To put things in perspective, idling for just 10 minutes consumes more fuel than restarting an engine after a night’s rest.
3. Health and Environmental Concerns
Speaking of environmental impact, idling contributes to the release of greenhouse gases, which adversely affect our climate. Moreover, prolonged exposure to carbon monoxide can pose health risks, including heart disease, stroke, and even cancer. Volatile organic compounds (VOCs) released during idling can lead to headaches and nausea, as highlighted by the WHO International Agency for Research on Cancer (IARC). By skipping the warm-up and heading straight onto the road, you’re contributing to a healthier environment and safeguarding your well-being.
When Should You Warm Up Your Car?
1. Cold Climates and Overnight Parking
While it’s generally best to avoid lengthy warm-ups, there are exceptions. If your vehicle has braved the frigid outdoors all night, it’s advisable to let it idle for a minute or two. This brief moment allows fluids to circulate efficiently, ensuring your car’s readiness for the road. Additionally, in icy or snowy conditions, a quick warm-up can help defrost your windows, ensuring optimal visibility and comfort.
2. Extreme Cold: A Short Burst
For those residing in extremely cold regions, a short burst of warm-up, around 30 seconds, may be warranted. However, be sure to keep your foot on the brake and your car in park or neutral to prevent fuel flow through the engine. Automatic transmission vehicle owners should take particular note of this precaution to avoid stalling.
Modern Technology: No More Warm-Up Worries
In today’s automotive landscape, modern cars are engineered to perform efficiently even in winter’s grip. Advanced components, including pistons, rings, coolant, and oil, work harmoniously to withstand extreme temperatures. These parts adapt swiftly to varying conditions, ensuring peak performance without a prolonged warm-up.
Modern vehicles are also equipped with sophisticated heating systems, eliminating the need for extensive idling. Your car is designed to warm up efficiently while you’re on the move, saving both time and fuel. If you desire a toasty interior before departing on a frosty morning or returning after a chilly day at work, simply turn on your high beams for approximately five minutes before shutting down—problem solved!
