What You'll Learn
Remove excess cargo and unnecessary items from your car
The weight of your vehicle has a direct impact on fuel efficiency. The heavier the vehicle, the more fuel it requires. Therefore, removing excess cargo and unnecessary items from your car is a simple yet effective way to improve fuel economy.
Start by identifying items that are not essential for your journey. This could include things like golf clubs, sports equipment, or boxes of items you're planning to donate. Be thorough and consider every item in your boot, trunk, and passenger seats. Even small items can add up, so don't underestimate the impact of removing multiple smaller items.
Next, consider the weight of your vehicle's accessories. Items such as roof racks, roof boxes, bull bars, or extended wing mirrors used for towing can significantly affect your vehicle's aerodynamics and increase drag. Remove these items when they are not in use. Additionally, opt for lighter accessories whenever possible. For example, choosing lighter bed and floor liners can further reduce weight and improve fuel economy.
It's also important to be mindful of the weight of your wheels and tires. Lightweight rims and low rolling resistance (LRR) tires can improve fuel efficiency. However, keep in mind that while LRR tires can help with efficiency, they may not provide the best traction or handling.
Finally, remember that the impact of removing excess weight may be more noticeable in smaller vehicles. Every 50 kg of extra weight can increase fuel consumption by 2%. So, by removing unnecessary items, you can significantly improve your vehicle's fuel economy and, as a result, save money on fuel costs.

Maintain your car and keep your engine well-lubricated
Maintaining your car and keeping the engine well-lubricated is essential for maximising fuel economy. Regular servicing is crucial to ensure the engine's health and longevity. Over time, sludge and corrosion can build up between engine parts, causing friction and making it difficult for the engine to run smoothly. This can be mitigated by using high-performance engine oil, such as Mobil™, which helps reduce friction, combat sludge, and improve fuel economy.
Lubrication of the engine and transmission (gearbox) is vital. Regularly renewing the air and oil filters, replacing spark plugs, and maintaining bearings and lubrication in the moving parts of the chassis can significantly improve fuel efficiency. Choosing the right engine oil lubricants can make a difference, with some options, such as Gulf engine oil lubricants, designed to improve fuel economy while maintaining engine health.
In addition to lubrication, maintaining and servicing other parts of your car is essential. Properly inflating your tires can improve fuel efficiency, and opting for lightweight rims and LRR (Low Rolling Resistance) tires can further enhance fuel economy. When it comes to accessories, removing unnecessary items like bike racks, roof racks, and cargo pods can significantly improve aerodynamics and reduce drag, resulting in better fuel mileage.
Another critical aspect of maintenance is keeping your engine running smoothly and evenly. Jerky or aggressive driving, with sudden acceleration and hard braking, can lower your fuel mileage. Instead, aim for smooth acceleration and maintain a steady speed to optimise fuel efficiency. Driving at a constant speed on a smooth route with minimal stops is ideal. Additionally, try to avoid peak traffic, as stop-start driving can burn more fuel and put pressure on your engine.
By prioritising regular maintenance and keeping your engine well-lubricated, you can significantly improve your car's fuel economy and, at the same time, extend the life of your engine.

Drive at a steady speed and avoid accelerating and braking suddenly
Driving at a steady speed and avoiding sudden acceleration and braking is a key way to improve fuel economy. This is because your vehicle uses more fuel when accelerating and gaining speed than when maintaining a constant speed. By driving in a stop-start fashion, you are causing your engine to work much harder, which in turn uses more fuel.
To avoid this, try to plan your route so that you can drive as smoothly as possible. This means avoiding congestion, junctions, interchanges and traffic lights where you will be forced to slow down and accelerate frequently. Instead, opt for routes with a constant speed limit, where you can maintain a steady speed without having to slow down or stop.
Additionally, when approaching a red light or hill, try to slow down gradually instead of slamming on the brakes at the last moment. Similarly, when driving up a hill, start accelerating before you reach it, rather than when you are already on it. This will help you maintain a steadier speed and improve your fuel economy.
Another way to drive at a more consistent speed is to use cruise control, which can help smooth out your throttling and reduce fuel consumption. However, it is important to note that cruise control should not be used on hilly terrain or slippery roads, as it can cause a loss of vehicle control in these conditions.
By driving at a steady speed and avoiding sudden acceleration and braking, you can significantly improve your fuel economy and reduce the amount of fuel you use.

Choose a smaller, lighter car
Smaller and lighter vehicles generally tend to have better fuel efficiency than bigger and heavier ones. The weight of a car is directly proportional to the amount of fuel it consumes. Every extra 50 kg reduces fuel efficiency by 2%, and an extra 100 pounds can reduce fuel economy by up to 1%. Therefore, removing unnecessary items from the car can help improve fuel economy. Items such as roof racks, roof boxes, bull bars, bike racks, and extended wing mirrors can increase drag and reduce the vehicle's aerodynamics, so removing them when not in use can improve fuel economy.
When choosing a smaller car, it is important to ensure that it meets your day-to-day driving needs. If you need a larger vehicle occasionally, you can always rent one. It is also essential to consider the fuel efficiency ratings of different models in the small car category and choose the most efficient combination of engine and transmission that meets your requirements.
In addition to choosing a smaller and lighter car, there are several other factors that can impact fuel economy. These include keeping your vehicle well-maintained, driving smoothly and evenly, limiting rapid acceleration and hard braking, and maintaining proper tyre inflation.
By combining a smaller and lighter vehicle with these fuel-saving practices, you can further improve your fuel economy and maximise your vehicle's efficiency.
Overall, choosing a smaller and lighter car is a significant step towards achieving better fuel economy, but it should be complemented by other good habits to fully optimise your vehicle's performance and fuel efficiency.

Use cruise control on the highway
Using cruise control on the highway is a great way to improve your vehicle's fuel economy. By maintaining a constant speed, you can reduce the number of times your vehicle slows down and accelerates, which is when your vehicle uses the most fuel. This keeps your engine and transmission operating in their most efficient modes, and as a result, your fuel economy will be higher.
Cruise control is especially useful when driving on mostly level ground or on long, steady uphill or downhill grades. Electronics are generally better at maintaining a constant speed than human drivers, whose acceleration can be affected by an inattentive mind or a weary ankle. However, on highways with rolling hills, it is better to manually adjust your speed, as cruise control is less effective at making these adjustments. In these cases, it is recommended to target an average speed and then allow your vehicle to slow down and accelerate as you climb and descend hills.
It is important to note that cruise control should not be used in heavy rain, snow, or at temperatures where ice could form. Any acceleration on slick surfaces or while hydroplaning can be dangerous and cause you to lose control of your vehicle. Additionally, while cruise control can help improve fuel economy, it is not always the most effective method. In some cases, a patient driver with a light throttle foot may be more fuel-efficient than cruise control, especially when climbing hills.
Overall, using cruise control on the highway can be a helpful tool for improving your vehicle's fuel economy, but it is important to be mindful of the limitations and potential dangers of this feature.
