Use your vehicle’s air conditioner as little as possible (within reason). The compressor puts a greater load on the engine, which reduces fuel economy. Park in the shade whenever you can, use a sunshade in your windshield and leave windows cracked for ventilation.
If the air pressure in your tires is imbalanced or low, your vehicle will burn more gas than necessary. Consult your owner’s manual for the optimal level of inflation and check your tire pressure at regular intervals.
