Lose the Weight
Driving around with tools, golf clubs, textbooks or other heavy gear is a waste of gas and money. Unload unnecessary cargo from your trunk before your road trip and save nearly $25 per year for each 100 pounds of weight you remove from your vehicle.
For every 100 extra pounds of cargo added to the vehicle, gas mileage drops about 1 percent. Lose the weight and save up to 6 gallons of gas and 120 pounds of CO2.
