Fuel Efficiency Tips for Highway Driving

Highway driving is where a car gets its best fuel economy, and the problem is that small habits can quietly erase that advantage, turning an efficient trip into an expensive one. The savings from better highway driving are real, often ten to fifteen percent, and over thousands of miles that is a meaningful amount of money back in your pocket.The single biggest factor is speed, because aerodynamic drag increases sharply above a certain point, and most cars get their best economy between fifty-five and sixty-five miles per hour, with every extra ten miles an hour costing several percent in fuel. Cruising at a steady speed in a high gear is the efficient way, while the constant accelerating and braking of aggressive driving wastes fuel without saving meaningful time.The habits that help are easy to adopt. Use cruise control on flat stretches to hold a steady speed, which burns less than a foot that constantly adjusts, keep the tires at the correct pressure, since underinflated tires add rolling resistance, and remove the roof box and excess weight when they are not needed, because both add
