With gas prices fluctuating, getting the most miles out of every gallon is a priority for many drivers. Improving your vehicle’s fuel efficiency doesn’t just save money—it’s also better for the environment. There are several simple ways to make your car run more efficiently, whether it’s by adjusting your driving habits or maintaining your vehicle. Here’s a breakdown of what you can do to improve fuel efficiency.
1. Keep Your Tires Properly Inflated
One of the easiest and most effective ways to improve your car’s fuel efficiency is to keep your tires properly inflated. When tires are underinflated, they create more rolling resistance, meaning your engine has to work harder to move the car. According to the U.S. Department of Energy, properly inflated tires can improve gas mileage by up to 3%. Make sure to check your tire pressure regularly using a tire gauge and adjust them to the manufacturer’s recommended pressure.
2. Change Your Oil Regularly
Regular oil changes not only keep your engine running smoothly but also improve fuel efficiency. Old or dirty oil can cause more friction in your engine, which forces it to work harder and burn more fuel. Using the right grade of motor oil is also important. Look for oil that’s labeled as “energy conserving,” which contains friction-reducing additives to help your engine operate more efficiently.
3. Lighten Your Load
Carrying extra weight in your vehicle can reduce fuel efficiency. The heavier your car, the more fuel it needs to move. Remove any unnecessary items from your trunk or back seat to lighten your load. While it might seem like a small change, reducing weight by as little as 100 pounds can improve your car’s fuel economy by about 1% to 2%. If you have a roof rack, remove it when not in use, as the added wind resistance can also decrease fuel efficiency.
4. Drive Smoothly
Your driving habits play a big role in how much fuel your car uses. Aggressive driving, such as rapid acceleration, speeding, and hard braking, wastes fuel. By driving smoothly and maintaining a steady speed, you can save gas. Using cruise control on highways can help you maintain a constant speed, reducing unnecessary acceleration and braking. Additionally, avoid idling for long periods, as idling burns fuel without getting you anywhere.
5. Keep Your Engine Tuned
An engine that’s out of tune can lower your fuel efficiency significantly. Routine maintenance like replacing spark plugs, cleaning or replacing air filters, and ensuring your fuel injectors are working properly can help your engine run at peak performance. A well-maintained engine uses fuel more efficiently, helping you save money at the pump.
6. Avoid Excessive Speeding
Driving faster than necessary wastes gas. Most vehicles are designed to operate at their peak fuel efficiency between 55 and 65 miles per hour. Once you exceed that range, fuel efficiency drops rapidly. For every 5 mph you drive over 50 mph, it’s like paying an extra $0.30 per gallon of gas. By keeping your speed within the optimal range, you can improve your vehicle’s fuel economy.
7. Use the Right Fuel
Make sure you’re using the fuel grade recommended for your vehicle. Using a higher-octane fuel than necessary won’t improve your car’s performance or fuel efficiency and will only cost you more money. Premium fuel is designed for high-performance engines that require it. For most drivers, regular unleaded is perfectly fine and won’t affect fuel efficiency negatively.
8. Turn Off the AC When You Don’t Need It
Running your air conditioning (AC) uses more fuel. If you’re driving at low speeds, consider rolling down the windows instead of using the AC. However, at higher speeds, having the windows down can create more drag and reduce fuel efficiency, so in those situations, it’s better to use the AC. Be mindful of when and how often you use your air conditioning to avoid unnecessary fuel consumption.
9. Check Your Alignment
Wheel alignment doesn’t just affect how your car handles—it can also impact fuel efficiency. When your wheels are misaligned, your car’s engine has to work harder to move the vehicle forward. Regularly checking your vehicle’s alignment and making adjustments when necessary can improve fuel economy and extend the life of your tires.
10. Plan Your Trips
Planning your trips efficiently can also help you save on fuel. Combining errands into one trip rather than taking several short trips will reduce the number of times your car’s engine needs to warm up. Cold engines are less fuel-efficient, so it’s better to make fewer trips with a warm engine. Additionally, avoid rush hour traffic when possible to prevent idling in stop-and-go traffic, which consumes more gas.
11. Upgrade to Fuel-Efficient Tires
When it’s time to replace your tires, consider investing in fuel-efficient tires. These tires are designed to reduce rolling resistance, which means your car doesn’t need to use as much fuel to keep moving. Fuel-efficient tires might cost a little more upfront, but they can help you save money on gas in the long run.
12. Consider Aerodynamics
The shape and condition of your vehicle can also affect its fuel efficiency. Roof racks, bike racks, and other items attached to the outside of your car can create extra drag, making your car less aerodynamic. This increases fuel consumption, especially at higher speeds. If you don’t need those accessories, remove them to improve your car’s aerodynamic profile and save on fuel.
Conclusion
Improving your vehicle’s fuel efficiency doesn’t require major changes—just a few small adjustments to your driving habits and maintenance routine. Keeping your tires properly inflated, driving smoothly, and maintaining your engine are all simple ways to make your car more fuel-efficient. With gas prices always on the move, following these tips can help you get the most out of every gallon while also reducing your carbon footprint. Plus, a well-maintained car runs better, lasts longer, and saves you money in the long run.
