Fuel consumption is a measure of how efficiently a vehicle uses fuel, comparable to fuel economy (or fuel efficiency). The fuel efficiency of motor vehicles can be expressed in multiple ways. Fuel consumption is the amount of fuel used per unit of distance, for example, litres per 100 kilometres (L/100 km). Fuel economy is the distance travelled per unit volume of fuel used, for example, kilometres per litre (km/L) or miles per gallon (MPG). The average American driver spends about $3,000 per year on gas, and there are many ways to reduce fuel costs.

Fuel efficiency
There are several factors that can impact a vehicle's fuel efficiency. One of the most significant factors is the type of vehicle. Smaller, lighter cars with less powerful engines tend to be more fuel-efficient than larger, heavier vehicles with bigger engines. Additionally, the number of wheels being powered also makes a difference—4-wheel drive vehicles are generally less fuel-efficient than FWD or RWD vehicles as the engine has to work harder to move the car at higher speeds.
Another factor that affects fuel efficiency is the maintenance and condition of the vehicle. Properly inflating your tires, using the recommended grade of motor oil, and keeping the engine tuned can all improve fuel efficiency. Removing unnecessary weight from the vehicle, such as a roof rack or bike rack, can also help. In addition, external accessories like spoilers and ground effects kits can increase drag, leading to higher fuel consumption.
Driving habits can also impact fuel efficiency. Driving at steady speeds on highways is generally more fuel-efficient than city street driving with frequent stops and diversions. Additionally, driving above speed limits can increase fuel consumption, as cars tend to achieve maximum efficiency between 40 and 50 mph (65 and 80 km/h). Idling can also reduce fuel efficiency, as an idle vehicle gets 0 mpg.
By understanding the factors that affect fuel efficiency, drivers can make informed choices to optimize their vehicle's performance and reduce fuel costs. This can include choosing fuel-efficient vehicles, maintaining proper tire pressure, planning fuel-efficient routes, and adopting fuel-saving driving habits.

Fuel consumption
There are several factors that influence a vehicle's fuel consumption. Firstly, the type of vehicle and its engine size can have a significant impact. Smaller, lighter vehicles with less powerful engines tend to be more fuel-efficient than larger, heavier vehicles with bigger engines. Additionally, the maintenance and condition of the vehicle can also affect fuel consumption. Properly inflating tyres, using the recommended grade of motor oil, and ensuring the engine is properly tuned can all improve fuel efficiency. External accessories, such as roof racks or spoilers, can increase drag and lead to higher fuel consumption.
Driving habits and conditions can also impact fuel consumption. Driving at higher speeds, particularly above 50 miles per hour, can increase fuel consumption. Highways are generally more fuel-efficient than local routes or city streets due to the ability to maintain a steady speed. Traffic jams and peak travel seasons can also contribute to higher fuel consumption. Additionally, environmental factors, such as hot climates, can affect fuel efficiency due to the increased use of air conditioning.
To calculate the cost of fuel consumption, one can use a fuel cost calculator. This takes into account the number of miles driven, the vehicle's average miles per gallon (MPG), and the current price of fuel. By dividing the miles driven by the MPG, one can determine the fuel consumption per mile. This value can then be multiplied by the fuel price to estimate the fuel cost per mile.
In summary, fuel consumption is an important factor to consider when budgeting for travel and can be influenced by various factors related to the vehicle, driving habits, and environmental conditions. By choosing fuel-efficient vehicles, maintaining proper vehicle conditions, and adopting conscious driving habits, one can optimise fuel consumption and reduce overall fuel costs.

Cost of fuel
The cost of fuel is a major expense for most drivers, with the average American driver spending about $3,000 per year on gas. The cost of fuel depends on several factors, including the distance travelled, the fuel efficiency of the car, and the price of gas.
Fuel consumption is a measure of how efficiently a vehicle uses fuel, typically expressed in miles per gallon (MPG) or litres per 100 kilometres (L/100 km). The fuel efficiency of a car can be improved by driving a smaller, lighter car, removing unnecessary weight, and ensuring proper tyre inflation. Additionally, using the manufacturer's recommended grade of motor oil and keeping the engine properly tuned can also enhance fuel efficiency.
To calculate the cost of fuel for a trip, you can use a fuel cost calculator. This involves determining the number of miles driven, the vehicle's average MPG, and the current price of gas. By dividing the miles driven by the MPG, you can estimate the cost of fuel for the trip.
It is worth noting that driving above the speed limit can significantly increase fuel costs. According to the U.S. Department of Energy, for most vehicles, every five miles driven over 50 MPH results in an additional $0.24 paid in gas. Therefore, it is advisable to maintain speed limits and plan routes carefully to maximize fuel efficiency.
Furthermore, reducing the number of miles driven is the most obvious way to save on fuel costs. Opting for walking, biking, or using public transportation can significantly reduce fuel expenses. Proper maintenance of the vehicle, such as fixing serious issues like a faulty oxygen sensor, can also improve fuel mileage by up to 40%.

Vehicle weight
However, it is important to note that vehicle weight is not the only factor that affects fuel efficiency. Vehicle optimizations and hybrid powertrains can significantly improve fuel efficiency, even for heavier vehicles. For example, fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve mileage by up to 40%. Ensuring proper tire inflation can reduce fuel consumption by up to 3%. Using the manufacturer's recommended grade of motor oil can also improve gas mileage by 1-2%.
Additionally, external accessories such as ornaments, ground effects, and spoilers increase the car's drag and lead to higher fuel consumption. On the other hand, carpooling is more fuel-efficient than multiple people driving separate cars to the same destination, even though a heavier car consumes slightly more fuel.
In summary, while vehicle weight does impact fuel efficiency, there are also many other factors that play a role. Optimizing these factors can help improve fuel efficiency, even for heavier vehicles.

Fuel economy metrics
There are several ways to express fuel economy. In countries that use the metric system, fuel economy is usually stated as "fuel consumption" in litres per 100 kilometres (L/100 km). This is also known as "energy intensity", where the input is measured by the amount of fuel and the output is measured by the distance travelled. In some countries, fuel economy is expressed in kilometres per litre (km/L or kmpl). In the US and UK, fuel economy is usually expressed in miles per gallon (mpg), although there is sometimes confusion as the imperial gallon is 20% larger than the US gallon, so mpg values are not directly comparable.
Fuel consumption is the reciprocal of fuel economy. It tells us how much fuel a vehicle burns at a certain distance, for example, in litres per kilometre (L/km). This is a more accurate measure of a vehicle's performance because it is a linear relationship, whereas fuel economy can lead to distortions.
There are several factors that influence fuel economy, including engine efficiency, transmission design, and tyre design. Driver behaviour can also have an impact, with sudden acceleration and heavy braking wasting energy. Properly inflated tyres can reduce fuel consumption by up to 3%, and fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve mileage by up to 40%.
