Is Warming Up the Car in Winter Necessary?

In the winter time, getting out of bed and facing the day is just a little bit harder. I, personally, need to take a moment to prepare with a cup of coffee to warm me up. But what about the cold vehicles we are about to climb into to take us where we need to go – don’t they need some warm up time, too? Despite a common misconception, the answer is actually no.

While cars used to require warming up in the days of carburetor fuel systems, today’s cars are equipped with fuel-injection technology, computer systems, and thinner synthetic oils. These new developments make warm ups unnecessary in newer cars.

Instead of warming up your vehicle by letting it idle, try taking it easy as you hit the road.

According to the Car Care Council, warming up, or idling longer that 30 seconds is unnecessary. A better way to warm up an engine is to drive slowly as you begin your trip. As you pull out of your driveway or parking lot, do not gun the engine, instead just take it slow for the first few minutes as you head down the road.

While warming up the car may not do anything for the car mechanically, starting your car before you are ready to go can get the car warmed up for your comfort. Keep in mind, though, warming your car does have some drawbacks. Idling reduces fuel economy and causes excessive wear or stress on engine components, such as cylinders, spark plugs, and the exhaust system. Another reason why warming up is not such a great idea is pollution.  A vehicle that idles for more than 30 seconds increases air pollution.

It is easy to underestimate the impact of one car, but together, we can make a significant reduction in air pollution.
