Achieving optimal fuel efficiency isn’t just about cutting costs—it’s also a responsible choice for the environment. Start by maintaining a steady speed on highways, as constant acceleration and deceleration can increase fuel consumption by up to 30%. Use cruise control when possible, but avoid it in hilly terrain or heavy traffic where frequent adjustments are needed. Regular tire maintenance is another key factor: underinflated tires create more rolling resistance, forcing the engine to work harder. Check your tire pressure at least once a month (preferably when the tires are cold) and keep them inflated to the manufacturer’s recommended PSI, which you can find on the driver’s side door jamb or in the owner’s manual. Additionally, reduce excess weight in your vehicle—every 100 pounds of unnecessary cargo can lower fuel efficiency by about 1-2%. Remove roof racks or carriers when not in use, as they create aerodynamic drag that wastes fuel. Finally, avoid idling for more than 30 seconds; modern engines warm up faster while driving, and idling for just 10 minutes a day can waste up to 3 gallons of gas per month. By combining these habits, you can improve your car’s MPG by 10-15% over time.
