BOSTON (CBS) – If all the snowstorms weren’t bad enough, it has also been a cold winter, and we do what we can to stay warm.

Kim from Norwood Declared her Curiosity about letting her car run for fifteen minutes every morning so it’s nice and toasty before she drives away. She asked: “How much gas do I actually use while it’s warming up?”

The AAA says a good rule of thumb is that you use a quarter of a gallon of gas for every fifteen minutes you idle.

So, if you do that five days a week, you’re burning about $4 worth of gas and getting zero miles per gallon.
