Poor Maintenance: Delaying or neglecting your car's maintenance can significantly increase fuel consumption. To avoid this, ensure your mechanic is skilled, or take your car to a dealership certified by your car's manufacturer. Certified dealerships usually have the right tools and equipment to care for your vehicle correctly, though they tend to be more expensive than local mechanics. Keep a service schedule in your car to track maintenance dates, ensuring timely servicing.

Short Distances: Cars consume the most fuel when starting a journey, particularly on short trips when the engine hasn't warmed up. To optimise fuel efficiency, try to complete as many errands as possible in one outing. Short trips, especially those under five kilometres, are generally less fuel-efficient. Combining multiple short trips into one longer journey can improve your car's fuel economy and save time.

Faulty Engine: An improperly tuned engine or delayed servicing can lead to higher fuel consumption. This often results from issues like worn-out spark plugs, clogged filters, faulty oxygen sensors, or damaged engine valves. Dirty or malfunctioning fuel injectors can also cause the engine to burn fuel more quickly. Replacing faulty engine components promptly will improve fuel efficiency and prevent more severe damage.

Weight: A vehicle's weight directly impacts its fuel consumption. Lighter vehicles, such as compact cars, require less energy and, therefore, less fuel than heavier vehicles like trucks or SUVs. Additionally, smaller vehicles often have smaller engines that don't need to work as hard to generate power. Between vehicles of similar size, the materials used in their construction can influence their weight and fuel efficiency.

Engine Displacement: Engine displacement refers to the volume of air an engine uses in a single revolution, typically measured in litres. Larger displacement engines require more fuel to move because they push more air during operation. The greater the displacement, the more fuel the engine consumes while driving.

Aerodynamic Efficiency: Aerodynamics plays a crucial role in fuel economy by reducing drag and air resistance as the vehicle moves. Vehicles designed with smooth curves and sleek shapes are more aerodynamic and, therefore, more fuel-efficient. Taller, boxier vehicles, like trucks, encounter more air resistance, leading to higher fuel consumption. A vehicle's design is often optimised to minimise drag and improve efficiency.
