For many people, starting up their ice cube of a car and letting it warm up a bit is something that we don’t really think about because it was something that’s always been done. Our parents did it because their parents did it or you hear how someone had a friend who didn’t warm up their car and the engine blew up and so on.
It turns out in modern vehicles, the practice of idling your car during the winter is no longer needed. In fact, most manufacturers and auto experts recommend driving off gently after about 30 seconds. You are actually hurting the engine, wasting gas, and polluting the environment when warming it up for much longer than that.
