Tired of Exorbitant Fuel Bills?

You may have heard several pieces of advice on saving fuel by using methods like carpooling or using public transport. Here is a guide that will help you with some simple driving and maintenance fuel efficient techniques that can save gas prices.

Excessive usage of fuel is not only damaging your pocket but also the environment. It is high time you took full charge to maximize your miles, learn how to save gas while driving, and minimize your fuel costs. Paying attention to specific driving and vehicle maintenance tips can help you gain some fuel savings, improve road safety, and mitigate carbon dioxide emissions.

Critical Facts Related to Fuel Savings Through Driving and Maintenance

Before we start with our top 10 best practices, here are some facts laid out by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) in the Fuel Economy Guide. These facts back up our claims and help you understand how can you save fuel when driving. Little changes make massive differences!

  1. If you drive aggressively or haphazardly, it can reduce your gas mileage by about 15%–30% on highways and 10%–40% in heavy traffic. Consider using driver feedback devices to improve fuel efficiency. Such automated devices can enhance your driving habits and augment fuel economy by approximately 10%.
  2. Stick to the speed limit, as driving just 5 MPH over 60 MPH can lower fuel efficiency by 7%. Minimize idling, which burns fuel without moving and can cost up to $0.02 per minute.
  3. Using cruise control on highways can help maintain a steady speed and typically save fuel. Don’t ignore engine issues, and have your vehicle regularly inspected. This will prevent fuel waste and save money in the long run.
  4. Maintaining appropriate tire pressure can improve fuel economy by about 0.6%. Additionally, ensure your tires are aligned and balanced.
  5. Using the correct grade of motor oil can also enhance fuel efficiency by 1%–2%. Replacing a clogged air filter can improve gas mileage, especially in older cars that come with carbureted engines.
  6. Avoid carrying unnecessary items, as every extra 100 pounds can reduce fuel economy by approximately 1%. Furthermore, refrain from placing too much load on the trunk or roof, as it can significantly decrease fuel efficiency, reducing it by 2%–8% in city driving and 6%–17% on highways.


10 Fuel-Saving Best Practices Through Driving and Maintenance


Do you want to know how to save fuel while driving?

Considering the facts given above, here are some expert gas saving tips and techniques that can help you save fuel charges through driving and maintenance:

  1. Maintain a Steady Speed

The best way to save gas while driving is to avoid extremes in speed. While driving on the highway, going too fast can increase fuel consumption, while, driving too slowly can force your engine into a lower gear. Both situations can enhance fuel usage. Stick to a consistent speed between 50 km/h and 90 km/h for the best fuel economy. 

Avoid slamming those brakes harshly, as you again have to accelerate, which would result in fuel waste. It is equally significant to predict traffic flow and adjust your speed accordingly. Decelerating can also save fuel by avoiding unnecessary stops and starts. The key is to maintain consistency when driving and keep your foot steady.

  1. Utilize Cruise Control

On highways, use cruise control to maintain a steady speed. This can help you avoid unwanted speed changes, which results in reducing fuel consumption. When driving uphill, don’t press hard on the gas pedal. Instead, let the vehicle’s momentum carry you.

If driving an automatic car, use cruise control to keep a constant speed. On the other hand, shift to higher gears when driving a manual car. This will keep engine revolutions per minute and maximize fuel efficiency. Such steps can help you understand how to save fuel when driving.

  1. Reduce Weight

Extra weight in your car means burning more fuel. Remove unnecessary items and clear off the roof too. Remember that rooftop carriers create wind resistance, which can affect fuel economy.

It has been researched that for every extra 50 kg of weight in your car, fuel consumption can increase by 2%. 

  1. Use Vehicle AC Wisely

It is often believed that turning the car’s AC off and driving with rolled-down windows saves fuel. However, driving with windows down at speeds over 80 km/h creates wind resistance, which can lead to higher fuel consumption.

Using air conditioning is often more fuel-efficient and can improve fuel efficiency by up to 10%. 

  1. Maintain Proper Tire Pressure

Low tire pressure deprecates tires faster, increases resistance, and makes it difficult for the car to move smoothly. You must check tire pressure frequently and inflate them to the recommended level. Wheels that are underinflated can mitigate fuel efficiency by up to 10%, so it’s crucial to keep them properly inflated.

  1. Install Driver Feedback Devices

Research from the National Center for Sustainable Transportation shows that feedback systems installed within the vehicle can help drivers improve fuel efficiency by around 6.6%.

These devices warn the driver with audio alerts and let them assess their behaviors like idling, speeding, and harsh braking. Such devices further allow drivers, to make real-time adjustments to save fuel. By using AI-enriched devices, you can monitor and improve driver behavior, which is one of the most critical fuel efficient driving techniques that can lower fleet costs. 

  1. Use a Fuel Consumption Display

Many vehicles now come with fuel consumption displays that show how driving habits affect fuel usage. Acting on the feedback from these displays can help drivers reduce fuel consumption by up to 15%. Plan your trips efficiently and choose the best road trip cars, which can reduce the frequency of refueling, ultimately lowering monthly fuel costs.

Opt for four-lane highways over city roads, which have frequent stops and intersections. Help your vehicle’s engine reach its most fuel-efficient temperature and plan your vehicle’s use efficiently.

  1. Use the Right Fuel

Use the fuel that is recommended. If your car recommends premium fuel, you must only use it to maintain optimal engine performance and fuel efficiency. Using a lower-grade fuel may lead to engine issues and increased fuel consumption, negating any savings per liter.

Some vehicles offer different drive modes, so besides choosing the right fuel, stick to the right mode of driving to optimize engine performance. Adhering to such factored vehicle settings can maximize fuel efficiency.

  1. Minimize Idling

Turn off your engine if you anticipate being parked for more than a couple of minutes. Many vehicles now have a pre-installed engine function, temporarily shutting off the engine when you’re stopped.

It restarts when you release the brake. It is recommended to turn your vehicle engine off if you’re waiting for more than three minutes. Restarting the engine uses about the same amount of fuel as keeping the vehicle idle for 30 seconds, so it’s better to turn it off when you can.

  1. Maintain Your Vehicle

Last, but not the least, regular vehicle maintenance keeps your engine running efficiently. If you notice increased fuel consumption, it could mean a faulty sensor. Proper maintenance includes checking your vehicle engine health, wheels, air filter, and vehicle oils.

Following the vehicle’s maintenance schedule strictly can improve fuel efficiency by up to 10%. Always keep maintenance records to ensure compliance with and use AI-enriched software and devices to streamline maintenance tracking and scheduling.


In this modern world, it is important to consider environmental sustainability besides cost-savings. You must significantly transform your driving habits and maintain your vehicles to keep them in good shape and save long-term fuel costs. Such ways to save gas while driving can create a noticeable difference.

So, if you can’t remember the last time you got your vehicle serviced, it may be time to consult a professional. This is especially helpful for fleet businesses that aim to maximize fuel efficiency. It is important for every vehicle owner to invest in fuel-efficient cars, adhere to preventative maintenance schedules, and conduct a thorough cost analysis to identify areas for reducing fuel consumption.
