Have the wheel alignment checked on your vehicle. A four-wheel alignment will ensure the vehicle tracks straight down the road and the tires are pointed straight ahead. This decreases rolling resistance and improves fuel economy. While the alignment is checked, have the technician check the brakes for drag. A seized or binding brake caliper has the same effect as you driving with your foot on the brake.
