With gas prices continuing to climb, it's important to know how to increase your car's fuel average to save money. Fuel efficiency describes how well a vehicle can use fuel, while fuel economy refers to the specific number of miles per gallon (MPG) that a vehicle can drive. There are several ways to increase fuel efficiency, such as maintaining tyre pressure, removing unnecessary items from the car to reduce weight, and improving driving habits.
How to Increase Car Fuel Average
| Characteristics | Values |
|---|---|
| Driving Speed | Limit the rate at which you gain speed. Generally, around 80-100 kph (50-60 mph) offers the best balance between good progress and maintaining good fuel economy. |
| Gears | Driving in a high gear will improve fuel economy. If your vehicle has an automatic transmission, select the economy mode. If it's manual, change up earlier yourself. |
| Tyre Pressure | Check your tyres every few weeks to maintain the recommended pressure. Under-inflated tyres increase friction between the road and tyre, reducing fuel efficiency. |
| Tyre Type | Choose narrow tyres with low-rolling-resistance. This reduces aerodynamic drag. |
| Vehicle Weight | Keep the vehicle as light as possible. Remove unnecessary items from the boot, trunk, and passenger seats. |
| Air Conditioning | Limit the use of air conditioning as it is a heavy user of fuel. However, opening windows at higher speeds can also decrease fuel economy. |
| Route Planning | Plan your trips ahead of time and choose the most direct route to reduce the need to slow down or stop. |
| Vehicle Maintenance | Service your vehicle and replace components as per the manufacturer's recommended intervals. Check the oxygen sensors, engine emissions system, and evaporative emissions control systems. |
| Fuel Quality | Check the fuel quality before tanking up. Avoid filling fuel from small and dodgy-looking outlets. |

What You'll Learn
Maintain tyre pressure
Maintaining tyre pressure is one of the simplest ways to increase your car's fuel average. Under-inflated tyres are one of the leading causes of tyre failure, and they can also cause a significant decrease in fuel economy. A study by the National Highway Traffic Safety Administration (NHTSA) in the USA found a strong correlation between tyre pressure and fuel economy. Every 1% decrease in tyre pressure resulted in a 0.3% reduction in fuel economy. This means that an under-inflation of 10% increases fuel consumption by 2%, and an under-inflation of 20% increases fuel consumption by 4%. Tyre pressure can also be affected by temperature changes. For every 5 °C drop in temperature, there is a 2% loss in tyre pressure, and for every 5 °C rise, tyre pressure increases by 2%.
To maintain proper tyre pressure, you should check your tyres every few weeks. The proper tyre pressure for your vehicle can usually be found on a sticker in the driver's side door jamb or the glove box, and in your owner's manual. It is important to note that you should not use the maximum pressure printed on the tyre's sidewall. Regularly checking your tyre pressure is easy and can save you hundreds of dollars over the life of the tyres.
When replacing your tyres, you can choose a higher economy rating to increase the distance you travel per litre or gallon of fuel. You can also select narrow tyres, as they have less frontal area, reducing aerodynamic drag. However, keep in mind that narrow tyres have less traction. Additionally, consider choosing low-rolling-resistance compound tyres, as they can increase fuel economy by a few per cent.
By maintaining optimal tyre pressure and choosing the right type of tyres, you can improve your vehicle's fuel economy, increase your mileage, and save money on fuel costs.

Remove unnecessary items
To increase your car's fuel average, it is important to remove unnecessary items from your car. This is because the weight of the car has a direct impact on fuel efficiency. The heavier the car, the more fuel it will consume.
Extra bags, books, shoes, garbage, and other non-essentials can quickly add up and weigh down your vehicle, requiring it to use more fuel to power it forward. Even an extra 100 pounds can increase fuel consumption by 1-2%. Therefore, it is important to remove any unnecessary items from your trunk and backseat. If you have seats that you don't use, consider removing them to reduce the weight of your car.
However, it is important to note that removing items from your car can also increase wind resistance, which can decrease fuel efficiency. For example, driving with empty roof racks can decrease fuel efficiency by up to 20%. So, it is important to find a balance and only remove items that are truly unnecessary.
Additionally, when removing items from your car, make sure to keep the essential safety items, such as your spare wheel. Removing these items could be dangerous and may even be against the law in some countries.
By removing unnecessary items from your car, you can significantly increase your fuel efficiency and save money on gas.

Avoid aggressive acceleration
Aggressive acceleration wastes fuel. A car uses the most fuel when it is accelerating, as it requires more energy to increase speed than to maintain it. Therefore, limiting the rate at which you gain speed can increase the distance you travel for every litre or gallon of fuel used.
Aggressive driving, including speeding and rapid acceleration and braking, can lower gas mileage by 15-30% at highway speeds and 10-40% in stop-and-go traffic. Driving sensibly and gently is safer and more fuel-efficient.
To avoid aggressive acceleration, you can use cruise control to maintain a smooth and economic speed, especially on multi-lane highways and roads. Driving in a high gear will also improve fuel economy, as the lower the engine speed (rpm or revs), the less fuel the engine will consume at a steady speed. If your vehicle has an automatic transmission, you can select the economy mode, which will ensure the car changes up to the next gear as soon as possible. If your vehicle has a manual transmission, you can change up earlier yourself. Many modern cars will indicate when you should change gear, helping you increase fuel economy.
In addition to gentle driving, you can also improve fuel efficiency by removing unnecessary items from your car, including heavy items and wind-resistant items on the outside, like cargo boxes and bike racks.

Use cruise control
Cruise control is a feature in most modern vehicles that allows you to set a desired speed for the car to maintain automatically. Once activated, the system controls the throttle and keeps the car at a steady pace without needing continuous input from the driver.
Using cruise control can help improve fuel economy in certain situations, such as driving at a consistent speed on open roads and highways. By eliminating fluctuations in speed caused by human input, cruise control minimises unnecessary acceleration and deceleration, which tend to waste fuel.
For example, when driving on mostly level ground or long, steady uphill or downhill grades, cruise control can help maintain a smooth and economical speed. It is beneficial to use cruise control when tackling uphill climbs, especially if your vehicle has an adaptive system. More advanced technology can adjust throttle inputs and gear ratios more efficiently, optimising fuel consumption and power output during ascents.
However, there are instances where cruise control may not be the best choice. Using cruise control in heavy traffic or on winding roads with multiple inclines and declines may lead to increased fuel consumption. This is because frequent speed changes caused by traffic dynamics or the need for constant adjustments on winding roads can render cruise control ineffective.
Additionally, it is important to exercise caution when using cruise control on steep inclines, as manual intervention may be required to ensure safety. It is also not recommended to use cruise control in inclement weather conditions, such as heavy rain, snow, or low temperatures where ice could form.
Overall, while cruise control can be a useful tool for improving fuel economy in certain driving scenarios, it is essential to consider other factors such as vehicle maintenance, driving habits, and traffic conditions, which also play crucial roles in fuel efficiency.

Plan your route
Planning your route is an effective way to increase fuel efficiency. There are several factors to consider when planning your route. Firstly, try to make one long trip instead of several short ones. This is because your car's engine operates more efficiently when it is warm. Therefore, plan your route to include multiple stops while keeping the engine warm, rather than constantly returning to your starting point.
Secondly, consider the speed limits on your route. Light-duty trucks, for example, are most efficient at between 40 and 50 miles per hour, with a significant drop in efficiency after 60 mph. While driving faster may reduce the time spent on the road, it does not necessarily reduce fuel consumption, as your engine will be less efficient.
Thirdly, plan your route to avoid high-traffic areas and peak traffic hours as much as possible. Traffic congestion can increase fuel consumption and cause stress. Utilize GPS apps to find alternative routes with less traffic, even if they are longer.
Fourthly, when planning your route, consider the weight and cargo of your vehicle. Every 100 pounds of added weight can cause a 1% decrease in miles per gallon, so only bring what is necessary for the trip. Similarly, ensure your tires are properly inflated, as this can save you up to 11 cents per gallon, according to the National Highway Traffic Safety Administration.
Finally, if you are managing a fleet of vehicles, consider using a delivery route planner or dynamic routing. This can help you optimize multiple delivery addresses and increase productivity. Fixed routing, where each vehicle follows the same route daily, may be effective for consistent customer bases, but it lacks flexibility and can be challenging for drivers to adapt to unexpected changes.
