What You'll Learn
Check tyre pressure and wheel alignment
Checking your tyre pressure and wheel alignment is an important step in increasing your car's fuel efficiency. Underinflated tyres create more resistance, causing your engine to work harder and burn more fuel. This is because tyres with low pressure create more friction, which results in lower fuel economy. If your tyre pressure is too high, it can make your ride uncomfortable and increase tyre wear. Therefore, it is important to maintain the recommended pressure. You can do this by checking your tyre pressure once a month and adjusting it according to the manufacturer's recommendations. Modern tyres have an economy rating that indicates their impact on fuel efficiency, so you can choose tyres that are more fuel-efficient.
In addition to tyre pressure, wheel alignment also plays a role in fuel efficiency. Mismatched tyres can cause drag and affect the smoothness of your ride, reducing your fuel economy by up to 10%. Therefore, it is important to get your wheel alignment checked and fixed as soon as possible. This can be done during routine maintenance or when you notice any issues with your tyres or wheel alignment.
Another factor to consider is the weight of your vehicle. A heavier car requires more fuel to move, so removing unnecessary items from your boot, trunk, or passenger seats can increase fuel efficiency. This includes items such as extra bags, books, or tools. Additionally, external features like roof racks, roof boxes, or bike racks can increase aerodynamic drag, especially at higher speeds. Removing these when not in use can improve fuel efficiency.
Planning your route in advance can also help you optimise fuel efficiency. By choosing the most direct route and avoiding busy traffic, you can reduce the amount of stopping and starting, which uses more fuel. Using a sat nav system can help you find the most fuel-efficient route, and driving at a slower, steady speed can also improve fuel economy.
Overall, by maintaining correct tyre pressure, ensuring proper wheel alignment, reducing vehicle weight, and planning your route efficiently, you can significantly increase your car's fuel efficiency and improve your vehicle's performance.

Remove unnecessary items from the car
The weight of your vehicle has a direct impact on fuel efficiency. The heavier the car, the more fuel it will consume. Therefore, removing unnecessary items from your car is a simple yet effective way to increase fuel efficiency.
Start by removing any extra items from your boot, trunk, or passenger seats. Items such as extra bags, books, shoes, tools, and sports equipment can quickly add up, making your vehicle heavier and reducing fuel economy. Even a small amount of extra weight can make a difference. For example, an additional 100 pounds in your vehicle can decrease gas economy by up to 1%.
Outside the car, remove any wind-resistant items such as cargo boxes, bike racks, and roof racks when they are not in use. These items can significantly affect your vehicle's aerodynamics and increase drag, making the engine work harder and consume more fuel.
It is also important to note that while removing unnecessary items can improve fuel efficiency, it is not recommended to remove essential safety items such as your spare wheel. Doing so could be inconvenient, dangerous, and, in some countries, against the law.
By regularly removing unnecessary items from your vehicle, you can not only increase fuel efficiency but also reduce weight-related strain on your engine, tires, and other components. This can lead to improved vehicle performance, reduced maintenance costs, and a smoother overall driving experience.

Avoid high speeds and quick acceleration
Driving at high speeds and accelerating quickly can significantly reduce your car's fuel efficiency. This is because your car requires more energy to increase its speed than to maintain it at a steady rate. Driving at high speeds can also increase aerodynamic drag, especially if you have items on your roof rack, and this can cause your vehicle to use more fuel.
To improve fuel efficiency, it is recommended to drive within the speed limit and to accelerate slowly and smoothly. Driving at a slower, steadier speed can improve your fuel efficiency by up to 20%. For example, driving at 65 mph instead of 75 mph can increase your fuel efficiency by up to 20%. Similarly, driving at 80 mph uses 25% more fuel than driving at 70 mph.
It is also beneficial to plan your route in advance to avoid traffic jams and stop-start driving, which can cause your engine to use more fuel. Using cruise control can also help to maintain a smooth and economic speed, especially on long highway trips and multi-lane highways and roads.
In addition to driving at lower speeds, removing unnecessary items from your car can also help to improve fuel efficiency. The heavier your vehicle, the more fuel it will require to move, so removing items such as golf clubs, tools, or other non-essentials can help to reduce weight and improve fuel economy.

Plan your route to avoid traffic
Planning your route efficiently is a great way to increase fuel efficiency and save money. By avoiding traffic jams and congested areas, you can reduce the amount of time spent on the road and the number of stops, which in turn reduces fuel consumption.
The impact of traffic on fuel efficiency
Traffic jams are a common occurrence due to the high number of vehicles on the road. They can cause significant delays and impact the productivity of delivery businesses, drivers, and regular motorists. Stop-start traffic puts pressure on your engine, causing it to burn more fuel. Additionally, aggressive driving behaviours such as speeding, rapid acceleration, and sudden braking can lower your fuel economy by up to 30% at highway speeds and up to 40% in stop-and-go traffic. Therefore, it is essential to plan your route to avoid these high-traffic areas and improve fuel efficiency.
Strategies for planning your route
- Utilize route optimization tools: Many navigation apps and software applications offer route optimization features that use algorithms to analyze real-time traffic data, road types, and user preferences to determine the most efficient route. These tools can help you identify routes with less traffic congestion, reducing the time spent on the road and improving fuel efficiency.
- Combine trips: Long excursions allow your engine to reach its fuel-efficient temperature. By combining multiple errands or deliveries into a single trip, you can reduce the number of cold starts and improve fuel efficiency.
- Plan ahead and keep track: Stay informed about the traffic conditions and be mindful of other vehicles' activities. This will help you anticipate potential delays and make necessary adjustments to your route.
- Avoid peak traffic hours: Whenever possible, plan your commute to and from work to avoid peak traffic hours. This will significantly reduce the time spent in traffic and improve your overall fuel efficiency.
By implementing these strategies, you can optimize your routes, reduce time spent in traffic, and increase fuel efficiency for your vehicle.

Regular maintenance and tune-ups
One of the most important things you can do to ensure your car is fuel-efficient is to keep up with regular maintenance and tune-ups. Little or poor maintenance of car parts can lead to major fuel consumption. This includes regular check-ups, servicing the engine, and changing your oil and replacing your filters regularly. Clean air filters improve airflow, helping your engine burn fuel more efficiently. Dirty filters can choke your engine, reducing airflow and fuel efficiency. Get your filters checked regularly and replace or clean them as needed. You can also add synthetic oil along with your engine oil to enhance fuel efficiency rates.
It is also important to keep an eye on your wheel alignment and tyre pressure. Mismatched tyres or underinflated tyres create more resistance, meaning your engine has to work harder and burn more fuel. This may result in a 10% reduction in your car's fuel economy. The greater the resistance to the road, the more fuel your vehicle will use to maintain speed. Keeping your tyres properly inflated can improve your gas mileage by up to 3%. It is recommended that you check your tyre pressure at least once a month. All tyres are provided with a manufacturer’s tyre pressure recommendation, which gives the best balance of grip, comfort, long life and fuel economy.
It is also a good idea to get to know your vehicle and how to best optimise its fuel consumption. Learn about the care it needs and its different driving modes to understand how to make your vehicle fuel-efficient. For example, driving beside tyres causes friction, which raises fuel consumption. The fuel economy of your automobile is also determined by the tyre's fuel efficiency rating. According to their fuel economy, tyres are categorized by the European Commission from A to G. Compared to G-rated tyres, A-rated tyres may increase fuel efficiency by up to 7.5%.
