To most people, the most obvious way to save gas is buying a new car that gets better gas mileage. But before you head to the dealer to make your trade-in, you should know that there are easier ways to save money on gasoline. Do you stop short at traffic lights and then make a jack-rabbit start? Do you weave in and out of traffic? Driving more sensibly can save you 5%-33% on your gasoline costs. Driving the speed limit can save you another 7%-23%. It is estimated that every 5 miles you drive above 60 miles per hour is comparable to spending an additional $0.20 on gas. Using your cruise control can also save gas since it regulates your speed. Additionally, using your overdrive gears when climbing hills can help. Excessive idling wastes fuel as well so you might want to consider turning off your car if you need to wait for someone or are completely stopped in traffic.
