What You'll Learn
- Declutter your car to reduce weight and improve fuel efficiency
- Avoid idling, rapid acceleration, and driving in the wrong gear
- Keep tires properly inflated to reduce rolling resistance and friction
- Choose a smaller, hybrid vehicle for lower fuel costs
- Drive smoothly, avoid over-acceleration and over-braking
Declutter your car to reduce weight and improve fuel efficiency
Keeping your car free of clutter is an effective way to improve fuel efficiency. The more weight in your car, the more petrol it uses, so removing unnecessary items can help to reduce fuel consumption. This is especially true for city driving, where you are frequently accelerating, and for driving at slow speeds, where drag from extra weight is more noticeable.
Roof racks, roof bars, and cycle racks can weigh around 5kg and significantly increase aerodynamic drag, so removing them when they are not in use can make a big difference to your fuel efficiency.
Infrequently used items in your boot or backseat could be adding unnecessary weight. For example, items like prams, kids' scooters, and beach gear are not needed for every trip, so consider removing them when they are not required.
You can also improve fuel efficiency by focusing on driving smoothly. Avoid over-acceleration, over-braking, and sudden stops, as these waste energy and increase fuel consumption. Instead, practice gradual acceleration and early braking, and keep your inputs smooth by changing gears as quickly as possible.
Finally, consider removing spare seats, sound insulation, and other heavy items that are not essential for your trips. Each car will vary, so assess your own vehicle to identify areas where weight can be reduced.

Avoid idling, rapid acceleration, and driving in the wrong gear
Idling, rapid acceleration, and driving in the wrong gear are all factors that negatively impact fuel efficiency.
Idling, or leaving the engine running while the vehicle is not in motion, consumes fuel and increases costs. This is particularly costly for businesses operating fleets of vehicles. For example, medium-heavy trucks weighing between 19,700 and 26,000 pounds waste approximately 0.84 gallons of fuel per hour when idling. Idling for prolonged periods can also cause mechanical degradation, leading to even higher fuel consumption and engine damage. Additionally, idling releases harmful toxins and greenhouse gases, contributing to poor air quality and environmental damage.
To improve fuel efficiency, it is advisable to turn off the engine if you anticipate idling for more than 10 seconds. This simple action can help reduce fuel wastage and minimize the negative environmental impact of idling.
Rapid acceleration, or stepping hard on the gas pedal, also decreases fuel efficiency. Accelerating requires more energy than maintaining a steady speed, and accelerating quickly demands even more energy. As a result, rapid acceleration leads to increased fuel consumption and higher costs. To optimize fuel efficiency, it is recommended to gradually build energy over time rather than immediately flooring the accelerator. This allows for a more efficient utilization of the engine and can help you reach the "cruising sweet spot" where fuel consumption is significantly reduced.
Driving in the wrong gear can also impact fuel efficiency. While the ideal operating conditions vary for each vehicle, engines generally run most efficiently at their peak torque, wide-open throttle, and the lowest RPM possible. To achieve better fuel efficiency, it is important to understand your vehicle's specific engine characteristics and adjust your driving habits accordingly.

Keep tires properly inflated to reduce rolling resistance and friction
Keeping your tires properly inflated is one of the most important things you can do to improve your car's fuel efficiency. Underinflated tires can increase fuel consumption by as much as 3%, and if all your tires are underinflated by 10 psi, this could reduce fuel efficiency by up to 10%. This is because underinflated tires have a higher rolling resistance on the road, which means that with every kilometer traveled, your tires generate more friction and rolling resistance, increasing fuel consumption.
Checking your tire pressure regularly is important, especially during winter when temperatures can cause a drop in pressure. You can find the correct PSI for your tires in your owner's manual or on the sticker on the inside of the driver's door. Maintaining proper tire pressure will not only improve your car's fuel efficiency but also help prevent premature wear on your tire treads and reduce the risk of a blowout.
In addition to keeping your tires properly inflated, there are other simple steps you can take to improve fuel efficiency. These include removing clutter and unnecessary weight from your vehicle, driving smoothly and avoiding rapid acceleration and hard braking, and limiting idling. Regular car servicing and maintenance, such as oil changes and air filter replacements, can also help to maintain your engine's fuel efficiency.

Choose a smaller, hybrid vehicle for lower fuel costs
If you're looking to save on fuel costs, choosing a smaller, hybrid vehicle is a great option. Hybrid vehicles combine a gasoline engine with an electric motor, resulting in improved fuel efficiency compared to their gas-only counterparts. The electric motor provides additional power, making these cars responsive and smooth to drive, especially in urban areas.
The fuel efficiency of hybrids is further enhanced by regenerative braking, which captures the car's momentum as it slows down or coasts, converting it into electricity. This feature, along with the inherent efficiency of the drivetrain technology, contributes to the impressive fuel economy of hybrids, with some models achieving over 40 mpg.
While the upfront cost of a hybrid vehicle tends to be higher, the improved fuel efficiency can lead to significant savings over time. In some cases, the additional cost of a hybrid can be offset by reduced fuel costs and even lower insurance rates. Federal and state governments often offer tax credits to encourage the purchase of hybrid vehicles, making them more financially accessible.
When considering a smaller, hybrid vehicle, it's worth noting that advancements in technology have made modern hybrids more budget-friendly, versatile, and enjoyable to drive. They also offer lower emissions and require less maintenance compared to traditional gasoline-powered cars.
By choosing a smaller, hybrid vehicle, you can expect lower fuel costs, improved driving dynamics, and reduced environmental impact, making it a smart choice for both your wallet and the planet.

Drive smoothly, avoid over-acceleration and over-braking
Driving smoothly and avoiding over-acceleration and over-braking is a key aspect of fuel-efficient driving. The force applied to the accelerator pedal directly impacts fuel consumption, with harder acceleration leading to higher fuel usage. Gradual acceleration and early braking are effective strategies to enhance fuel efficiency. For example, taking five seconds to accelerate to 20 kilometres per hour from a stop can significantly improve fuel economy.
Maintaining a steady speed is crucial for reducing fuel consumption. Small adjustments in speed, such as varying between 75 and 85 kilometres per hour every 18 seconds, can increase fuel usage by up to 20%. Smooth driving techniques, such as avoiding rapid acceleration and sudden braking, help maintain a consistent speed, improving fuel efficiency. Additionally, driving at moderate speeds between 50 and 80 kilometres per hour is generally more fuel-efficient than higher speeds.
Cruise control is a valuable feature that assists in maintaining a steady speed, particularly on highways. By reducing unnecessary acceleration and braking, cruise control can improve fuel economy, especially during long-distance trips. It is also beneficial to anticipate traffic flow and adjust your speed accordingly to minimise the need for sudden stops or rapid acceleration.
Removing clutter and unnecessary items from your vehicle can also contribute to smoother driving and improved fuel efficiency. Excess weight increases fuel consumption, so decluttering your car and removing roof racks when not in use can enhance fuel economy. Additionally, keeping your tires properly inflated can improve fuel efficiency by up to 3%.
Overall, adopting a smooth driving style, avoiding over-acceleration and over-braking, utilising cruise control, decluttering your vehicle, and maintaining proper tire inflation are effective strategies to maximise fuel efficiency and reduce fuel costs.
