It may seem hard to believe that you can improve your Toyota Prius’ gas mileage, but you can with a few minor changes in your driving style and a couple of after market parts. Here’s how.

Keep your tires properly inflated and rotate them on a regular basis. Improperly inflated tires can rob 15% of a Toyota Prius’ gas mileage.

Constant lane changes and/or speeding up then slowing down can dramatically impact fuel efficiency. You could see as much as 10 mpg improvement by changing these driving habits.

Regularly change your air filter.

If you normally drive with your windows down and your sunroof open, add wind deflectors to each of them. An open window or sunroof adds aerodynamic drag to your car, robbing fuel efficiency. A wind deflector will reduce that drag.

It is not hard to improve your Toyota Prius gas mileage. For the most part, all you have to do is drive sensibly and perform scheduled maintenance.
