Go Light on the Pedal
Many government and commercial vehicles don’t stick to the speed limit merely because it’s the law; it’s also the speed at which most vehicles get their very best mileage.
- Most engines are tuned for optimum mileage just below the typical interstate speed limits.
- As a rule, 60mph is the sweet spot, and every five miles per hour that you drive over that uses up to seven percent more gas to maintain those speeds.
Maintaining speed also naturally uses less gas than accelerating, so make good use of your car’s cruise control on long road trips. Your wallet will thank you for it!
