Stretch every gallon: Practical advice for better gas mileage

To improve gas mileage, compare local prices using apps like GasBuddy and opt for stations offering Top Tier fuel. Maintain at least a half-tank during winter or potential shortages, and ensure tires are properly inflated for optimal fuel economy and safety. Avoid relying solely on Eco Mode, and instead focus on smooth driving habits and removing unnecessary cargo to enhance aerodynamics.
