Hypermiling is way of driving whereby your gas mileage is considerably increased and can be implemented in easy steps. Although hypermiling is safe for your car, as you take these steps to increase your gas mileage, you must be aware of other traffic. Because you will be driving in a way slightly different than what other drivers expect, you must take the responsibility for ensuring that you are driving safely.

The first step to hypermiling starts before you get into your car. Unload anything unnecessary from your trunk, take in anything you don't need on this trip into the house, and, if you're not carrying anything on the roof of your car, remove any roof racks or other structures that will inhibit gas mileage and take them into the house. Check your tire pressure and make sure that your tires are inflated to the recommended pressure.

The second step to hypermiling starts before you turn the key in the ignition. Make sure that your and your passengers' seat belts are fastened, and the radio is on your preferred station, and that the heating or cooling is adjusted the way you like it. Only when you are ready to pull out of your parking space should you turn your car on. Let it warm up for only ten seconds, then put the car into gear and slowly accelerate.

As you are driving, do your utmost to maintain a perfectly constant speed. Look ahead two traffic lights, and be aware of when they will turn red (you can glance at pedestrian crossing lights to give you an idea). If you are driving up to a light you know will be turning red, or is red, take your foot off the gas and coast to a stop, or coast as close as you can get before you must step on the brake. If your lights are timed, once you get in the flow, drive at the stated speed limit to keep in the flow of the lights. when the light turns green, accelerate slowly and gently. If you are going to be stopped at a light for more than ten seconds, turn your car off (unless it is cold). Watch the lights so that you can turn your car on again just before they change.

Everyone knows that you speed up when you're going uphill, to maintain a constant speed. And you let off the gas downhill, because the momentum will carry you forward. Studies have shown that this is the most wasteful way to drive hills. In fact, you should do exactly the opposite. Speed up to the speed limit as you are going downhill, because less additional momentum is needed to reach the speed limit. Then let your foot off the gas as you go uphill; ideally, you should arrive at the top of the hill with just enough momentum to carry you over the top and start the downward acceleration all over again. Again, do not do this in traffic as you will make a lot of people angry--but for late-night driving you'll notice a significant reduction in your gasoline use!

When you are parking, make sure that you can see all around you, so that you start your car only when you can pull out into traffic, to avoid idling.

By following these steps, you can expect an increase in your gas mileage of up to fifteen per cent. That's like having extra money in your pocket--and the more you drive, the more you will save!
