There are many ways to save fuel in your car, from driving habits to vehicle maintenance. Driving smoothly and maintaining a steady speed are key to fuel efficiency, as well as looking ahead and keeping a safe distance from the car in front. Keeping your tires at the correct pressure and removing unnecessary weight from your vehicle can also help, as underinflated tires and extra weight increase fuel consumption. Planning your trips efficiently and using cruise control can further reduce fuel usage. Finally, regular car servicing and the use of high-performance engine oil can improve fuel economy by reducing friction and keeping your engine in good condition.

Maintain correct tyre pressure
Maintaining correct tyre pressure is a simple yet vital practice to ensure your car is fuel-efficient. It is one of the most common aspects of a car that drivers neglect, but it can make a significant difference to your fuel consumption and your wallet. Underinflated tyres can increase fuel consumption by up to 4%, and every 1% decrease in tyre pressure correlates to a 0.3% reduction in fuel economy. This is because underinflated tyres have a higher rolling resistance, which means more of the tyre's surface area touches the road, increasing friction and wear. This leads to a reduction in fuel efficiency and the longevity of your tyres.
You can find the correct tyre pressure for your vehicle on a sticker in the driver's side door jamb, the glove box, or in your owner's manual. It is important to note that you should not use the maximum pressure printed on the tyre's sidewall. Checking your tyre pressure is simple and can be done with a tyre pressure gauge, which measures the PSI of your tyres. For the most accurate reading, check when the tyres are cold as heat can cause tyre pressure to rise. It is recommended to check your tyre pressure at least once a month and more frequently during significant weather changes, as temperature fluctuations can impact tyre pressure.
By maintaining optimal tyre pressure, you can improve your vehicle's performance, decrease fuel costs, and extend the lifespan of your tyres. It is also important for your safety on the road, as underinflated tyres are among the leading causes of tyre failure.
To make maintaining tyre pressure easier, you can invest in a reliable tyre inflator gauge, which will help you keep your tyres at their ideal pressure and improve fuel economy over time.

Plan your route and drive smoothly
Planning your route and driving smoothly are two of the most effective ways to save fuel in your car. Here are some tips to help you do this:
Plan your route
Before you set off, take a few minutes to plan your route. Check a map and try to avoid roads with lots of stoplights, intersections, and pedestrians. These obstacles will require you to stop and start your car frequently, which wastes fuel. Instead, opt for a route with fewer interruptions, even if it is slightly longer. This will allow you to drive more smoothly and maintain a more consistent speed. If you're combining multiple trips into one, plan your route to be as seamless as possible. This will not only save time but also fuel, as your engine won't have to go through multiple warm-up cycles.
Drive smoothly
Once you're on the road, focus on driving as smoothly as possible. This means maintaining a steady speed and avoiding sudden acceleration or deceleration. Look ahead while you drive and anticipate what other drivers and pedestrians are going to do. This will help you adjust your speed gradually rather than having to brake or accelerate suddenly. Keep a comfortable distance from the vehicle in front of you to avoid unnecessary stops and starts. If you're driving a manual car, try to stay in a higher gear when appropriate. This will reduce the number of revolutions per minute (RPM) your engine makes, leading to lower fuel consumption.
Slow down
When it comes to saving fuel, it's important to slow down. The faster you drive, the more fuel your car will consume. Most cars are most fuel-efficient when travelling between 50 and 80 km per hour. Above this speed range, fuel consumption increases significantly. For example, at 120 km per hour, your vehicle uses about 20% more fuel than at 100 km per hour. So, when you can, take it slow and stay within the speed limit to maximize fuel efficiency.

Remove unnecessary weight from your car
To save fuel, it is important to remove unnecessary weight from your car. This is because the heavier the car, the more fuel it consumes. For example, the fuel consumption of a mid-size car increases by about 1% for every 25 kilograms of weight it carries. Therefore, it is advisable to unpack the car when you get home and leave only what you need for your next trip.
If you are going on vacation, it is advisable to combine all your trips into one. Making a list of what you need and mapping out the route will save time and gas. This is because warming up the car engine consumes gas and energy, and combining trips means fewer warm-ups.
In addition, it is important to remove items such as salt, sand, and sports equipment from your vehicle. These items can add significant weight to your car, increasing fuel consumption. It is also worth considering removing the back seats and passenger seats if you do not need them.
Furthermore, keeping your tires properly inflated can also help reduce fuel consumption. Underinflated tires have higher rolling resistance, increasing fuel consumption by up to 10%. Therefore, it is important to check your tire pressure regularly and ensure that your tires are inflated to the recommended pressure.

Servicing and engine oil
Additionally, engine oils play a crucial role in reducing friction and improving fuel economy. High-performance engine oils can help combat sludge and corrosion, improving the engine's performance. It is advised to use good quality, energy-conserving (EC) oils with a viscosity grade consistent with the manufacturer's recommendations. The owner's manual can provide guidance on the appropriate grade of motor oil for your vehicle. Using the recommended grade of motor oil can improve fuel economy by 1-2%.
Changing your oil regularly and according to the recommended schedule is also essential for maintaining fuel efficiency. While it may be tempting to change the oil frequently, it is important to follow the manufacturer's guidelines to ensure optimal performance and fuel economy. Over time, engine oil can break down and become less effective, so changing it at the recommended intervals helps to maintain engine performance and fuel efficiency.
Furthermore, proper maintenance of your vehicle, including regular servicing and timely oil changes, can help ensure you get the most out of your fuel tank. By keeping your car in good condition, you can maximize its fuel efficiency and minimize fuel consumption. This proactive approach can lead to significant savings in fuel costs over time.
In conclusion, servicing and engine oil play vital roles in saving fuel in your car. By maintaining your vehicle through regular servicing, using high-performance engine oils, and changing the oil as recommended, you can improve fuel efficiency, reduce friction, and optimize engine performance. These simple yet effective measures can help you save fuel and, ultimately, money on your fuel costs.

Avoid aggressive driving
Aggressive driving can reduce fuel mileage by up to 33%. So, to save fuel, it's important to avoid weaving through traffic, hard braking, revving the engine, and slamming on the gas. Here are some tips to help you avoid aggressive driving:
Look ahead and maintain a steady speed
Keep your eyes on the road and look ahead to anticipate what other drivers and pedestrians are doing. This will help you maintain a steady speed and avoid unnecessary braking and acceleration, which waste fuel. Drive at a consistent speed, especially on highways, and use cruise control if your car has this feature.
Maintain a comfortable distance
Keep a safe distance from the vehicle in front of you to avoid tailgating. This will help you avoid sudden stops and reduce the need for hard acceleration, which can increase fuel consumption by up to 30%.
Plan your route
Plan your route in advance to avoid roads with heavy traffic, multiple intersections, and stoplights. This will help you maintain a steady speed and reduce the need for frequent stops and starts.
Avoid rapid acceleration
When starting from a stop or climbing a hill, gently press the accelerator pedal to gradually build up speed. Rapid acceleration can increase fuel consumption and put unnecessary strain on your engine.
Keep your tires properly inflated
Underinflated tires can increase fuel consumption by up to 10%. Check your tire pressure regularly and maintain the recommended pressure listed on the sticker inside your driver's side door or on the tire information placard.
