Whether you’re looking to cut costs, use less fuel, or reduce your environmental impact, most drivers in Tullahoma & Winchester want to maximize their gas mileage. We’ve all heard various fuel-saving tips, but do they really make a difference? How much can simple maintenance and smarter driving improve your fuel efficiency?
Luckily, the U.S. government has studied this, and the numbers speak for themselves. Let’s break down some practical ways to keep more money in your wallet and get the most out of every gallon.
The Importance of Regular Maintenance
A well-tuned engine runs more efficiently, and a simple tune-up can improve gas mileage by 4%. That translates to savings of about 14¢ per gallon when gas is $3.50 or 16¢ per gallon at $4.00.
Certain repairs can make an even bigger impact. A faulty oxygen sensor, for example, can significantly hurt fuel economy because it prevents your engine from maintaining the right fuel-to-air ratio. Replacing a bad oxygen sensor can improve fuel efficiency by up to 40%! That’s a huge difference, making regular check-ups at Russell Barnett Automotive Family a smart investment.
Ignoring a check engine light can also cost you at the pump. Many issues that trigger this warning light directly affect fuel efficiency. If yours is on, let our team in Tullahoma & Winchester diagnose the problem and help you save gas.
Tire Pressure and Oil Choices Matter
Did you know that properly inflated tires can improve your fuel economy by 3%? Even a small drop in pressure can have an impact, so checking your tires weekly is a simple but effective way to save.
Using the right type of motor oil for your vehicle is another easy fix. The correct oil viscosity can boost fuel efficiency by 2%, so always follow your manufacturer’s recommendations.
Your Driving Habits Make a Big Difference
Unlike maintenance, adjusting your driving style doesn’t cost a thing—but it can lead to serious savings.
Aggressive driving—like rapid acceleration, hard braking, and weaving through traffic—wastes fuel. Taking a more controlled, steady approach on the road can save up to 5% in the city and an impressive 33% on the highway.
Speeding is another major factor. Even going just 5 mph over the speed limit can reduce fuel economy by 7%, while driving 15 mph over can cost you 23% more per gallon. Slowing down not only improves safety but also helps stretch your gas budget.
Declutter Your Car for Better Efficiency
Carrying unnecessary weight in your vehicle makes your engine work harder, which reduces fuel efficiency. Removing 100 pounds of extra weight can improve gas mileage by 2%. So, clean out your trunk and avoid using your car as a storage space!
The next time someone asks for a lift, you might jokingly say, “Sure, but you’re costing me extra at the pump!”
Make Smart Changes and Start Saving
By keeping up with regular maintenance, adjusting your driving habits, and reducing excess weight, you can make every gallon of gas last longer. Small changes add up, and the result is a healthier car, a thicker wallet, and a smoother ride.
