As chillier temperatures set in across most of the United States, many are likely stepping outside to warm their vehicles up for a bit to ensure it’s ready to go and hit the road in the cold.
But, it actually does more harm than good. We thought it would be an appropriate time to discuss warming a car up as winter officially arrives.
Engineering Explained does an excellent job at explaining why warming a car up isn’t the best idea with modern cars. The notion we must start the car and let it run for five or ten minutes is actually outdated and comes from the days of carburetors. Carbs needed a couple minutes to reach an optimal temperature in order to operate normally.
But with fuel injection, the ECU is able to reach optimal idle conditions in just a few moments. Letting your car sit and warm up can also allow gasoline to seep into engine oil, which in turn breaks down the oil’s lubrication properties. Warming your car up can potentially cause more wear and tear.
And nothing will warm a vehicle up faster than gently driving it around until the engine reaches its sweet spot on the temperature gauge. Then, it’s nothing but warm heat coming from the blowers and a toasty drive in.
