Knowing how much fuel to put in your car is important for maintaining your vehicle and can help you save money on fuel costs. The type of fuel you use depends on your vehicle's engine and octane rating, which can be found in the owner's manual. Diesel engines, for example, require diesel fuel, while some vehicles may require premium fuel. The amount of fuel you need depends on factors such as the size of your tank, fuel efficiency, and distance travelled. Properly inflated tires, driving style, and engine tuning can also impact fuel consumption. Additionally, carpooling and public transportation are alternatives to reduce fuel costs. Understanding these factors can help you make informed decisions about fuelling your vehicle and optimize your fuel usage.

What You'll Learn
Fuel efficiency of vehicles
Fuel efficiency is a measure of how much energy a vehicle can extract from a given amount of fuel. It is typically measured in miles per gallon (MPG) or litres per 100 kilometres. The fuel efficiency of a vehicle depends on several factors, including the type of fuel used, the vehicle's weight and drag coefficient, engine efficiency, drive train losses, and the amount of regenerative braking (in the case of hybrid or electric vehicles).
In the United States, the Corporate Average Fuel Economy (CAFE) standards set fuel efficiency targets for different types of vehicles. For example, the CAFE standard for 2-wheel drive light trucks was 16.0 mpg in 1980, while 4-wheel drive light trucks had a lower standard of 14.0 mpg. The sales-weighted harmonic average of the combined passenger car and light truck fuel economies is used to represent the fuel efficiency of light-duty vehicles.
To improve fuel efficiency, it is generally recommended to choose vehicles with smaller engines, hybrid or electric powertrains, and aerodynamic designs. For example, the Prius, Civic Hybrid Hatchback, and Kia Niro are often cited as fuel-efficient options. Additionally, proper tyre inflation and regular maintenance can also help improve fuel efficiency.
When considering fuel efficiency, it is important to note that fuel storage and transportation have specific guidelines and regulations. For example, in the UK, you can store up to 30 litres of petrol at home or non-workplace premises without a licence, but larger quantities require notification to the local Petroleum Enforcement Authority (PEA). Additionally, spillage of fuel on road surfaces can create hazardous conditions for other road users and should be avoided.

Cost-saving measures
There are several cost-saving measures one can take to reduce fuel consumption and, in turn, reduce costs.
Firstly, consider the type of vehicle you are using and the efficiency of its engine. Driving a smaller car, such as a small sedan, can significantly reduce fuel costs compared to a larger vehicle like an SUV. Similarly, opt for a vehicle with a smaller engine—a four-cylinder engine will use less fuel than an eight-cylinder one, unless you routinely haul heavy loads. Keep your vehicle's engine properly tuned to maximize power and enhance fuel efficiency. It is important to note that tuning the engine to increase horsepower will likely result in higher fuel consumption.
Another way to reduce fuel costs is to carpool or share rides with others travelling to the same destination. Carpooling with even one other person can reduce fuel consumption and costs by almost half. Additionally, consider walking, biking, or using public transportation as these options do not incur fuel costs.
To optimize your vehicle's fuel efficiency, ensure that your tires are inflated to the correct levels. Properly inflated tires can reduce fuel consumption by up to 3%. Check your tire pressure regularly, preferably weekly, as tires lose about 1 PSI per month and their pressure decreases in colder temperatures. Inflate your tires to the pressure recommended by the car manufacturer, which can usually be found in the user manual.
Lastly, when planning longer trips, utilize tools such as fuel cost calculators to estimate fuel costs based on factors like fuel efficiency, distance, and fuel price. These calculators can help you make informed decisions about your mode of transportation and anticipate fuel expenses.

Fuel consumption calculators
For example, a fuel consumption calculator can help determine the fuel consumption per 100 km by dividing the amount of fuel used in litres by the distance in kilometres and multiplying the product by 100. This can also be calculated for other units of distance, such as miles.
There are several online calculators that can be used to estimate fuel costs. One such calculator is the Fuel Economy Trip Calculator, which allows users to edit vehicles to personalise the MPG and fuel prices. The calculator also enables users to modify the route by dragging the route line on the map, which will update the cost of fuel for the trip.
Additionally, fuel consumption calculators can provide practical ways to reduce fuel costs. For instance, carpooling or using public transportation are more fuel-efficient options than driving separately or using private cars. Driving a smaller car or one with a less powerful engine can also significantly reduce fuel costs. Properly inflating tires can also reduce fuel consumption by up to 3%.

Tyre inflation
Firstly, locate the valve stem on your tyre. This is usually covered with a plastic or metal cap to protect it from dirt and debris. Remove the cap by twisting it counterclockwise and set it aside safely.
Next, attach the air compressor hose to the valve stem. If you are at a gas station, you may need to insert coins or tokens to activate the air machine. Set the machine to your desired PSI (pounds per square inch). You can find the correct PSI for your vehicle in the owner's manual or on a sticker on the inside of the driver's door.
Now, inflate the tyre gradually, checking the pressure with a tyre pressure gauge to avoid over-inflation. You can do this by hand, pressing down on the hose for 45 seconds to a minute, or by using a digital pump that will automatically stop when it reaches the desired PSI. Remember to stop inflating once you reach the recommended pressure.
Finally, once the tyre is inflated to the correct pressure, remove the hose and replace the valve stem cap by screwing it back on tightly.

Public transport
The relationship between high ridership and increased service frequency and efficiency can lead to a reduction in vehicle miles traveled (VMT), congestion, and fuel used by private vehicles. The COVID-19 pandemic had a significant impact on public transit ridership, revenue, and operations, but the Bipartisan Infrastructure Law of 2021 allocates funds to support the recovery of public transit operations.
Employee passes and transit subsidies are effective incentives for corporate decision-makers to build mass transit ridership, conserve fuel, and reduce VMT. Employers may benefit from reduced investments for private car parking and a tech-savvy, energy-conscious image. Public transportation agencies are forming partnerships with transportation network companies and micromobility providers to improve mobility choices for customers.
Some public transportation agencies offer mobile ticketing apps or pre-loaded transit cards, which are sometimes interoperable with bike-sharing systems or micromobility services. Making bicycle or scooter storage available on buses or at transit stations can also enable travelers to move between transportation modes easily.

Frequently asked questions
A Boeing 747 uses approximately 1 gallon (4 litres) of fuel every second. Over a 10-hour flight, it might burn 36,000 gallons (150,000 litres) of fuel.
You can calculate the fuel cost of a trip by using a fuel cost calculator. This will estimate the cost based on fuel efficiency, distance, and gas price.
There are several ways to reduce fuel costs:
- Carpooling or using public transportation
- Driving a smaller car
- Driving a car with a less powerful engine
- Keeping your tires properly inflated
Fuel consumption is a measure of how efficiently a vehicle uses fuel. It tells us how much fuel a vehicle burns at a certain distance, e.g., in liters per kilometer (L/km) or liters per 100 kilometers (L/100km).
To calculate fuel consumption, divide the amount of fuel used by the distance travelled. You can then multiply this number by the fuel price to get the cost per mile or kilometre.
