How to Drive More Fuel Efficiently: Tips for Saving Gas and Improving Mileage
Published on Mar 03, 2025
Driving efficiently isn’t just about saving money at the pump; it’s also about reducing your environmental footprint. As someone who’s spent years trying to make my trips as fuel-efficient as possible, I’ve learned several techniques and habits that can significantly improve how much gas I use, whether I’m navigating city streets or cruising on highways. Over time, these small changes in my driving behavior have added up to real savings, and I’m here to share the best ones with you.

1. Maintain a Steady Speed
One of the first lessons I learned about fuel efficiency was the importance of maintaining a steady speed. Rapid acceleration and frequent braking waste fuel by forcing your car to use more power than necessary. I found that keeping a constant speed, especially on highways, can do wonders for my gas mileage. This is where cruise control comes in handy. Whenever I’m on a long stretch of road, I engage the cruise control to avoid fluctuations in speed that can lead to unnecessary fuel consumption.
It’s tempting to speed up when you see an open road, but this can be a huge drain on fuel. I try to stay mindful of my speed, especially when driving on the highway, and avoid going too fast. Going over 65 mph can decrease your fuel efficiency by as much as 15%, so I make a conscious effort to keep my speed within the recommended range. By staying steady and avoiding the urge to speed, I not only save fuel but also reduce the wear and tear on my car’s engine.

2. Avoid Excessive Idling
Another thing I used to do without thinking was leaving my car running while waiting for someone or in traffic. However, I’ve come to realize that idling wastes more gas than I initially thought. In fact, for every 10 minutes my engine idles, I burn about the same amount of fuel it takes to drive a mile. If I’m waiting for longer than a minute or two, I turn off the engine. This is especially useful in situations like waiting at train crossings or long stoplights.
Turning off the engine and restarting it uses less fuel than leaving it running for long periods. I’ve also found that modern engines are designed to start quickly and don’t use much fuel in the process. If you’re idling for more than a few minutes, I highly recommend turning off your engine. It’s a simple but effective way to reduce fuel consumption and save money in the long run.
3. Keep Tires Properly Inflated
I never used to pay much attention to my tire pressure until I learned that under-inflated tires can decrease fuel efficiency by up to 3%. When my tires are underinflated, they create more rolling resistance, meaning my car has to work harder to move. As soon as I realized this, I made it a habit to check my tire pressure regularly, at least once a month, to ensure they’re properly inflated.
The ideal tire pressure can usually be found in the owner’s manual or on the sticker inside the driver’s door frame. I recommend checking the pressure when the tires are cold for the most accurate reading. Keeping your tires inflated to the manufacturer’s specifications not only improves fuel economy but also ensures better handling and safety on the road.
4. Lighten the Load
One of the easiest ways I found to increase fuel efficiency is by lightening the load in my car. The heavier the load, the harder my engine has to work, and the more fuel it burns. I used to carry around a lot of unnecessary items in my trunk, but now I’m more mindful of what’s inside. I try to keep only the essentials and remove anything that’s not absolutely necessary.
Also, if you’re someone who likes to carry a roof box or cargo carrier, be aware that these can also drag down fuel efficiency. If I’m not using the extra space, I remove the carrier to reduce wind resistance. It may seem small, but every little bit counts, especially when it comes to fuel efficiency.
5. Smooth Acceleration and Braking
It’s easy to fall into the habit of harsh acceleration or braking, especially when I’m in a hurry. However, I’ve learned that smooth, gradual acceleration and braking can have a significant impact on fuel consumption. When I accelerate too quickly or slam on the brakes, it forces my engine to work harder, burning more fuel in the process.
By gently pressing the gas pedal and braking gradually, I can maintain better control of my car while improving fuel efficiency. I’ve noticed that I use far less fuel when I drive with this technique, particularly in stop-and-go traffic, where frequent braking and acceleration are common. It’s not just about being smooth with the pedal, but also about planning ahead to avoid sudden stops or rapid acceleration. It might feel like I’m going slower at times, but in the long run, it’s much more fuel-efficient.
6. Use the Air Conditioning Wisely
As much as I love a cool breeze during hot summer months, I’ve realized that using the air conditioning can put a strain on my engine and cause a dip in fuel economy. When I drive at low speeds, I usually roll down the windows to get some fresh air. However, when I’m cruising on the highway, I prefer to use the air conditioning sparingly because it can reduce my fuel efficiency by up to 20% when used excessively.
If it’s particularly hot, I might turn on the air conditioning briefly and then turn it off once the cabin cools down. I’ve also learned that setting the air conditioning to the lowest temperature setting doesn’t cool the car any faster, so I try to avoid cranking it up to full blast. By being mindful of how often and how much I use the A/C, I’ve been able to reduce fuel consumption and keep my driving more efficient.
7. Plan Your Routes Ahead of Time
One of the most effective fuel-saving strategies I’ve adopted is planning my route ahead of time. I try to avoid getting caught in traffic jams or taking longer routes unnecessarily. With modern GPS systems and apps that show real-time traffic information, I can quickly identify faster routes and avoid areas with heavy congestion.
Whenever I know I’ll be running errands or traveling for a longer distance, I try to combine multiple trips into one. This not only saves time but also helps me avoid the fuel-wasting habit of constant start-and-stop driving. When I take the most direct, efficient route, I use less gas and reduce wear on my car’s engine.
8. Regular Maintenance Checks
It’s no surprise that a well-maintained car runs more efficiently. Regular maintenance, such as oil changes, air filter replacements, and spark plug inspections, plays a huge role in ensuring my car is running at its best. I make it a point to stay on top of my car’s maintenance schedule, as a poorly maintained vehicle can consume more fuel than one that’s in tip-top shape.
Additionally, I ensure that my car’s engine is running efficiently by using the correct grade of motor oil and keeping up with other key maintenance tasks. A car that runs smoothly not only performs better but also maximizes fuel efficiency. If I notice anything unusual—such as strange noises or a decrease in performance—I take it to a mechanic to avoid any potential problems that could lead to fuel waste.
9. Drive During Off-Peak Hours
One last tip that has helped me save fuel is driving during off-peak hours. Traffic congestion is one of the biggest culprits for wasting fuel, especially in urban areas. When I can, I try to schedule my trips during times when the roads are less crowded, such as early mornings or late evenings. By avoiding rush hour traffic, I can avoid idling in stop-and-go traffic, which is a major fuel killer.
Additionally, driving during quieter times means less time spent searching for parking spaces or dealing with crowded streets, which ultimately helps me save both time and gas.
By incorporating these habits into my driving routine, I’ve noticed significant improvements in my fuel economy.
