How to Improve Fuel Economy (3)

 Air Resistance – Less Is More, Leave it all behind

Roof racks are usually great for creating more room for carrying more gear, however for fuel efficiency leave the roof rack, bike racks, ski racks and roof boxes off your car unless needed and being used.

Air resistance causes aerodynamic drag (friction), requiring more energy and therefore more fuel to be used to overcome the friction.

Despite how fancy or aerodynamic these additions may look, they add drag and decrease your fuel economy. You will be rewarded with better fuel economy for taking a little bit of time and effort to remove these additions from the car.
