Driving at higher speeds reduces your fuel economy significantly. It takes more fuel to maintain 65 or 70 mph than it takes to maintain 55 or 60 mph. The Department of Energy says that every 5 mph you drive over 60 mph represents a 7% reduction in fuel economy.

Use your cruise control when you can, especially on long stretches of highway travel.

Proper maintenance is the key to keeping your car running at peak efficiency and as a result will help keep your fuel economy as high as possible. Keep your oil and air filters fresh. Excessively dirty air filters will reduce your fuel economy.

Keep all non-essential items out of your car. A trunk full of non-essential items only adds excess weight to your car and uses more fuel to carry it around with you.
