Sagittarius: Daily green

You'll find that small changes reap huge rewards right now. Make sure your car tires are inflated properly: in this gas crunch, efficiency is crucial. Improperly pumped tires can reduce gas mileage by nearly a half a percent for every psi below the recommended level. Over time, you're just burning up fuel and money needlessly. Do a hands-on check once a month in warm weather, and every two weeks or so during the colder months.
