Fuel efficiency
There are several factors that influence a vehicle's fuel efficiency. Firstly, the type of vehicle is important. Smaller cars, for example, tend to be more fuel-efficient than larger SUVs. Similarly, a less powerful engine will use less fuel. Other factors include the weight of the vehicle, with heavier cars consuming more fuel, and the aerodynamics of the vehicle, where accessories and ornaments can increase drag and fuel consumption.
Maintenance of the vehicle is also key to fuel efficiency. Ensuring the engine is properly tuned can enhance fuel efficiency, although this is often done to increase horsepower. Fixing a car that has failed an emissions test or is noticeably out of tune can improve fuel mileage by around 4%. Keeping tyres inflated to the correct pressure can also reduce fuel consumption by up to 3%.
Beyond vehicle choice and maintenance, external factors such as the macroeconomic environment also play a role in fuel efficiency. The cost of crude oil, geopolitical instability, and government interventions such as taxation can impact fuel prices and, consequently, the overall fuel efficiency of a vehicle in terms of cost.

Car maintenance
The amount of fuel used weekly depends on several factors, including the distance travelled, the fuel efficiency of the car, and the price of gas. The average American driver spends about $3,000 per year on gas, according to the American Automobile Association.
Tyre Maintenance
Ensure your tyres are inflated to the correct pressure. Properly inflated tyres can reduce fuel consumption by up to 3%. Check your tyre pressure at least monthly, and preferably weekly, as tyres lose about 1 PSI per month and are subject to pressure changes due to temperature variations. The recommended inflation pressure is for cold tyres; add about 3 PSI if the tyres are warm. Always inflate to the pressure suggested by the car manufacturer, not the number stamped on the tyre.
Engine Tuning
A well-tuned engine can enhance fuel efficiency. Fixing a car that has failed an emissions test or is noticeably out of tune can improve gas mileage by an average of 4%. Fixing a serious issue, such as a faulty oxygen sensor, can improve mileage by up to 40%. Avoid adding accessories like spoilers and ground effects kits, as they increase drag and, consequently, fuel consumption.
Driving Habits
Plan your routes carefully to minimise stops, diversions, and traffic. Highways are preferable to local routes or city streets as they allow for a steadier speed, maximising fuel efficiency. When in a city, consider parking in a central location and walking or using public transportation to reach your destinations. Stop-and-go city driving can significantly reduce your gas mileage. Additionally, driving with less haste, especially when hauling more weight, can help conserve fuel.
Regular Maintenance and Inspections
Keep your car well-maintained to ensure optimal fuel efficiency. Regularly clean or replace spark plugs to maintain efficient engine performance. Clogged fuel injectors can also lead to increased fuel consumption, so cleaning or replacing them is essential. Change fluids and filters as needed, and consult a reputable mechanic to identify and fix any issues.
Alternative Transportation
Consider alternative transportation options to reduce fuel consumption. Walking, biking, carpooling, and using public transportation are all excellent ways to reduce your fuel costs and environmental impact.

Route planning
Firstly, it is important to consider the time of day when planning routes. While some roads may be free-flowing during the majority of the day, they can become congested during rush hour. Stop-and-go traffic can negatively impact both your route times and fuel efficiency. Utilize routing software to mark out routes based on the time of day and take advantage of open roads to maintain momentum and cruise efficiently.
Secondly, while shorter routes generally use less fuel, longer routes can sometimes be more fuel-efficient if the speed limits and ability to cruise without excessive acceleration are considered. Light-duty trucks, for example, are most efficient at speeds between 40 and 50 miles per hour, with a significant drop in efficiency after 60 mph. Thus, planning routes with speed limits within this range can improve fuel efficiency.
Additionally, utilizing a fuel-efficient route planner can be beneficial. Applications like Google Maps, Upper Route Planner, and FarEye offer features such as real-time traffic updates, elevation analysis, and turn-by-turn directions to help optimize routes, reduce fuel consumption, and lower emissions. These planners can identify areas of congestion, suggest alternative routes, and provide insights to make informed decisions about driving habits.
Finally, it is important to note that driving habits can also impact fuel economy. Aggressive driving and excessive speeds can reduce fuel efficiency. Additionally, carrying excess weight or hauling items on the vehicle's roof can decrease fuel economy. By combining efficient route planning with improved driving habits, significant fuel savings can be achieved.
