Here’s a simple way to improve your car’s efficiency in less than a minute per month. Low pressure in your car’s tires can decrease your fuel efficiency by about 3 percent. A simple pressure gauge can read your tire’s pressure, and your owner’s manual will tell you what pressure your car’s manufacturer recommends. Usually, your tire pressure will be just fine. But every few months you’ll need to add a little air, which you can do from an air pump at the gas station the next time you fill up.
