For drivers who live where the temperature drops below freezing, winter mornings aren’t much fun. Even worse, their vehicles have to deal with the cold, too. Drivers want their cars to warm up fast so that they’ll run properly — and so the heater will hurry up and work.
But what’s the best way to warm up your car when it’s cold? A lot of people believe you should let your vehicle idle until it reaches normal operating temperature. Others are convinced that you should let your car idle very briefly, then put it in gear and let it warm up as you drive. The truth is, just a quick warmup is best, in most cases.
