Avoid aggressive driving habits like rapid acceleration, braking hard and speeding
Aggressive driving habits such as rapid acceleration, braking hard, and speeding can significantly reduce fuel efficiency. By driving more calmly and avoiding sudden manoeuvres, you can improve your gas mileage by up to 33% on the highway and 5% in the city.
Firstly, avoid rapid acceleration. When approaching a red light or stop sign, take your foot off the gas early and allow your car to coast down to a slower speed until it is time to brake. Accelerate smoothly with light to moderate throttle. This allows the automatic transmission to upshift into higher gears sooner, reducing engine rpm and saving fuel. You can also make this easier by keeping a distance from the person driving in front of you, releasing the accelerator well before you have to turn, or getting up to speed quickly and maintaining the same speed.
Secondly, avoid braking hard. You can brake using the engine, which means that you release the accelerator completely (and still stay in gear). When you do this, the engine won't be supplied with any more fuel until you accelerate or brake again. The same is true by driving in as high a gear as possible, letting the engine run the car rather than boosting the combustion yourself.
Thirdly, avoid speeding. Increased speed is known to reduce the amount of gas in your tank at a faster rate. Driving at a slower and steadier speed will help you conserve fuel.

Remove unnecessary items from your car to reduce weight
The weight of a car has a direct impact on its fuel efficiency. Excess weight increases fuel consumption, so it is advisable to avoid carrying heavy items or tools that are not needed for your journey. For instance, those with a habit of keeping everything in the boot should reconsider and only carry what is essential. Every extra 50 kg of weight increases fuel consumption by 2%.
Removing unnecessary items from your car can significantly improve fuel efficiency and reduce weight. This includes taking out heavy objects from the trunk, backseat, and even the glove compartment. It is also beneficial to remove roof racks and carriers when they are not in use, as they create aerodynamic drag that reduces fuel efficiency, especially at higher speeds.
Additionally, it is important to keep your car well-maintained. Regular servicing helps maintain your engine's fuel efficiency. Engine parts work closely together, and if they are not properly maintained, sludge and corrosion will build up, making it harder for the engine to function smoothly. This is also where engine oils are essential. A good high-performance engine oil can help reduce friction in the engine, combat sludge, and improve fuel economy.
By removing unnecessary items and maintaining your vehicle, you can significantly improve its fuel efficiency and reduce weight, ultimately saving money on fuel costs and reducing your carbon footprint.

Keep your tires properly inflated to avoid increased fuel consumption
Keeping your tires properly inflated is one of the most important aspects of making your fuel last longer in your car. Underinflated tires can decrease your fuel efficiency by up to 3%, resulting in higher fuel consumption and increased emissions. This is due to the increased rolling resistance, which makes your engine work harder to move the vehicle.
To avoid this, it is recommended to maintain the proper tire pressure for your vehicle. You can usually find the correct PSI in the owner's manual, or on a sticker in the driver's side door jamb or glove box. Monthly pressure checks are advised to ensure your tires are at the correct PSI, and quarterly inspections should be carried out to look for signs of wear and tear.
The type of tire you use can also impact fuel efficiency. For example, larger, wider tires have higher rolling resistance and reduced fuel economy due to their increased contact area with the road. Conversely, smaller, narrower tires can improve fuel efficiency but may compromise handling and stability. All-season tires offer a good balance between fuel efficiency and performance, while high-performance tires have higher rolling resistance due to their maximum grip and handling capabilities.
Additionally, the tread design of your tires can also affect fuel efficiency. Tires with aggressive treads, such as off-road or winter tires, have higher rolling resistance due to their deeper grooves. For urban driving, it is recommended to use tires with a smoother tread to reduce rolling resistance.
Proper tire maintenance, including regular rotations and alignments, is crucial for optimal tire performance and longevity. This will help ensure that your tires are contributing to, rather than detracting from, your vehicle's fuel efficiency.

Use cruise control wisely to maintain a constant speed
Cruise control is a feature on some vehicles that allows the driver to set a speed and then take their foot off the accelerator while the onboard computer maintains the vehicle's speed. This can be especially useful on long drives on large, straight roads such as an interstate highway with cars travelling at a relatively constant speed.
Using cruise control can help you save fuel by limiting unnecessary acceleration and braking. It can also help you maintain a constant speed, which is more fuel-efficient than quick acceleration and deceleration, which waste fuel by drastically changing the vehicle's momentum.
However, cruise control should not be used in all driving situations. It is inappropriate in stop-and-go traffic, in bad weather conditions such as snow, ice, or heavy rain, on narrow or curvy roads, or when there are frequent speed limit variations. In these situations, the time and attention it takes to disengage the cruise control could lead to a crash.
It's also important to note that when using cruise control, you may be using more fuel than necessary. This is because, with cruise control, you are always holding down the throttle, which increases fuel consumption.
Overall, cruise control can be a useful tool for maintaining a constant speed and saving fuel, but it should be used wisely and only in appropriate driving conditions.

Plan your route and drive smoothly to reduce braking and acceleration
Planning your route and driving smoothly can help you reduce braking and acceleration, thereby making your fuel last longer. Here are some tips to help you achieve this:
Plan Your Route
If possible, plan your route before getting behind the wheel. Knowing the way ahead of time can help you anticipate traffic lights, stop signs, and potential hazards, allowing you to adjust your speed accordingly. This reduces the need for sudden braking and acceleration, which can consume a lot of fuel.
Drive Smoothly
- Avoid aggressive driving: Aggression does not equal speed. Avoid the temptation to 'chuck' your car into corners. Instead, ease into turns, allowing the weight to shift progressively to the outside of the car. Smooth driving reduces the chances of losing control and helps you maintain better grip and balance.
- Brake smoothly: Avoid stamping on the brakes. Instead, apply gentle, progressive pressure on the brake pedal. This keeps weight transfer spikes to a minimum and reduces the chances of wheel lock.
- Accelerate smoothly: Avoid rapid acceleration, especially in powerful cars, as it can lead to spinning wheels and loss of control. Use light to moderate throttle pressure, allowing your car to gradually build speed.
- Maintain a steady speed: Holding your accelerator steady helps maintain a constant speed. This steadiness reduces fuel consumption and improves fuel efficiency.
- Use cruise control: When driving on highways or open roads, use cruise control to maintain a steady speed. However, avoid using cruise control on slippery roads, as it may lead to a loss of vehicle control.
- Time the traffic lights: When driving in urban areas, adjust your speed to 'time' the traffic lights. This helps you avoid unnecessary stops and reduces the need for acceleration and deceleration.
- Coast to a stop: When approaching a red light or stop sign, take your foot off the accelerator early and let your car coast down to a slower speed until it's time to gently brake. This saves fuel and reduces wear and tear on your brakes.
- Upshift early in manual cars: If your car has a manual transmission, upshift as soon as possible without 'lugging' the engine. This technique helps save fuel and reduces engine rpm.
