I drive a 2016 compact SUV for my sales job, which involves a lot of highway miles, and I'm trying to improve my fuel economy to save on gas costs. I've already started using cruise control more and keeping my tires properly inflated, but I feel like I could be doing more. For other drivers who have successfully boosted their MPG, what specific driving habits made the biggest difference? Is there a real benefit to using premium fuel in a car that doesn't require it, and do those fuel system cleaners you add to the tank actually work? How much does using the air conditioning versus rolling down the windows at highway speeds really affect mileage, and are there any vehicle maintenance items beyond oil changes that have a noticeable impact?
