Calm Down! How to Drive Green
Less aggressive driving has the most significant impact on gas mileage.
April 5, 2008— -- For those who aren't racked by enough environmental guilt to buy a hybrid, driving green can mean any number of readily available and easy-to-implement solutions that can increase your gas mileage.
Regular maintenance and aerodynamics play a part. But, according to fuel-efficiency experts, less aggressive driving has the most significant impact on your MPGs.
"Acceleration is the greatest factor," says Philip Reed, consumer advice editor for automotive Web site Edmunds.com. "It wastes energy and gas and pollutes the environment."

For example, accelerating at speeds between 55 and 75 miles per hour on the highway can be especially wasteful since the car spends more energy to keep up with other autos. In general, slowing down even 5 to 10 mph can boost mileage dramatically.
"Driving faster won't get you there any quicker," Reed says. "Eventually you'll run into a red light and lose the ground you've gained. It's amazing the difference slowing down makes."
Of course, the kind of car you drive also makes a difference. At the end of the day, there's only so much you can do to increase the gas mileage on an Escalade or Excursion.
Too rushed to slow down? Regular auto maintenance such as scheduled oil changes and tire rotation may cost drivers initially, but the savings add up in the long run. Just keeping your tires inflated can boost your car's mileage anywhere from 3% to 4%, according to Ford's Vehicle Environment Engineering department.
Losing weight and increasing your car's aerodynamics also help you get the most of your miles. By losing accessories like roof racks and whale tails, drivers can greatly reduce drag. Need an excuse to clear out the trunk? Clearing your car of clutter will lighten your load and improve your fuel economy. Sebastian Blanco, editor of autobloggreen.com, even suggests filling up on half a tank of gas at a time.
"Sure, you'll be filling up more often," he says, "but you'll be driving more on each gallon."
