It seems we all would like both an attractive but yet affordable "green" vehicle. There are several tips on how to improve gas mileage that can make a lot of difference. And nowadays these tips are often linked with hypermiling terms, or techniques for gas conservation.

The first consideration may be to select a fuel efficient vehicle at the time of purchase. This is becoming more of a priority for manufacturers.

A key factor is to drive in a smooth manner without sudden spurts of speeding up or braking. Avoid screeching to a halt at the traffic lights and gradually increase speed when negotiating hills. Sitting idly in traffic uses more fuel so it's better to minimize short, urban journeys. Always keep in the highest gear possible, as low gears have to do more work to drive the car. When out on the highway, not going over the speed limit is the best advice on how to improve gas mileage. Keep to 55mph if possible.

Maintenance of your new or used vehicle is of paramount importance. Choose the recommended motor oil for the type of car, keep the engine well tuned and address any emission problems straightaway. Keeping an eye on air filters will also help to protect the engine and they will need to be replaced on a regular basis. Tire pressure is a factor too and tires should always be inflated to the recommended psi.

Various things can affect the performance of a vehicle. When considering how to improve gas mileage and implement hypermiling ideas, experts have installed car data chips to collect information in different situations. The type of driving affects fuel consumption and whether it is urban, rural or highway motoring. Even the contents of the trunk will have an effect. Overloading will increase drag and it's a good idea to go through the trunk and take out anything that isn't necessary. A heavily loaded roof rack will also cause the car to use more fuel.

Air conditioning is more of a complex issue when working out the best methods on how to improve gas mileage. Turning on the system does affect fuel consumption and it's advisable not to use it routinely without thinking but only if necessary. However, it's also apparent that winding a car window down causes more drag and fuel is used more that way. The best advice for this specific problem is to seek advice from the car manufacturer. Obviously, it's important to ventilate the car because a stuffy atmosphere can cause a driver to feel drowsy and that must always be the first priority.
