Does your gas work for you?

In order to get every drop you pay for fill up in the mornings when it is cooler outside. The hotter gas particles are, the more they expand. By filling up your tank in the morning, you get more gas because the particles are closer together and each gallon of gas will hold more gas particles. You may not notice a big dent in the bill, but you'll be able to get more gallon for your $3.45.
