People concerned with getting better fuel economy should monitor their driving. Reports say that vehicles use 15 percent more fuel at 62 miles per hour and 25 percent more at 68 MPH due to wind resistance. However, driving too slow can also cause you to use more fuel due to being in a lower gear.
One way people can improve their car’s fuel economy is to clear out any unnecessary clutter. Naturally, carrying more cargo in a vehicle means it will burn more gallons of fuel each mile the person drives. This is especially true for the rear of the car. By some estimates, vehicles use about 2% more fuel for every extra 110 pounds of cargo.
