What You'll Learn
Calculating fuel mileage manually
To calculate fuel mileage manually, you will need to record some information about your vehicle and the fuel you put into it. This can be done in several ways, depending on what information you have to hand.
Firstly, you can calculate your fuel mileage by dividing the number of miles travelled by the number of gallons of gas it took to refill your tank. This method is simple and direct but may not be the most accurate, as it relies on an approximation of the number of gallons refilled, based on the gauge of your tank.
A more accurate way to calculate fuel mileage manually is to fill your tank with fuel and record the trip starting odometer reading. Then, at the end of the trip, fill your tank again and record the number of gallons or litres it took to refill. This is the total number of gallons or litres used for the trip. You can then record the trip-ending odometer reading, which will be the starting reading for your next trip. This method gives you a more precise figure for the number of gallons or litres used, and therefore a more accurate calculation.
You can also calculate fuel mileage using trip distance. Simply enter the total distance travelled and the amount of fuel used for the trip. This method does not require you to refill your tank at the end of the trip, but you will need to keep track of the amount of fuel used.
Another way to calculate fuel mileage is to use a fuel mileage calculator. These are available online and can estimate fuel mileage based on odometer readings, fuel price per gallon, and the amount of gas in the tank. They can also calculate the fuel cost of a trip based on fuel efficiency, distance, and the price of gas.
It is worth noting that there are ways to improve your fuel mileage. For example, keeping your vehicle in good shape and removing unnecessary weight can help improve fuel efficiency. Properly inflated tires can also reduce fuel consumption by up to 3%.

Improving fuel mileage
Car Maintenance
- Keep your car well-maintained: Regular maintenance can improve fuel mileage. For example, replacing a dirty or clogged air filter can improve mileage by 15%.
- Check your spark plugs: Worn spark plugs can reduce gas mileage by 30%. It's recommended to replace them between 30,000 and 60,000 miles.
- Use the correct motor oil: Using the manufacturer's recommended grade of motor oil can improve mileage by 1-2%.
- Maintain proper tyre pressure: Under-inflated tyres can lower gas mileage by 0.3% per PSI drop. Properly inflated tyres can reduce fuel consumption by up to 3%. Check your tyre pressure at least monthly, and inflate to the pressure recommended by the manufacturer.
- Remove unnecessary weight: Heavier vehicles use more fuel. Removing unnecessary items can save you money on fuel.
- Clean your fuel injectors: Adding a fuel additive can help clean your fuel injectors and improve performance.
Driving Habits
- Plan your route: Drive shorter distances and plan your route to include the fewest stops and diversions. Take highways instead of local routes when possible, as a steady speed maximizes fuel efficiency.
- Slow down: Driving above 50 mph significantly decreases fuel mileage. Driving slower and maintaining a consistent speed with cruise control can save fuel.
- Avoid aggressive driving: Rapid acceleration, deceleration, and braking can lower gas mileage by up to 40%. Conservative acceleration and deceleration can result in significant MPG gains.
- Minimize idling: An idle vehicle gets 0 mpg. Avoid unnecessary idling, and turn off the engine if you'll be stationary for more than 10 seconds.
- Limit AC usage: Air conditioning can decrease fuel economy, especially in hot climates. Use AC only when necessary, and consider rolling up windows and using AC when driving at higher speeds.
- Consider alternatives: Carpooling, public transportation, walking, or biking are the most fuel-efficient options.

Tracking fuel usage
Use a Fuel Mileage Calculator:
There are many free fuel mileage calculators available online and as smartphone apps. These calculators can estimate fuel costs based on odometer readings, fuel price per gallon, the amount of gas in the tank, and the total distance travelled. Some calculators can also provide fuel rates, i.e., the cost per mile or kilometer.
Manual Calculation:
You can calculate your fuel mileage manually by dividing the number of miles travelled by the number of gallons of gas used to refill your tank. This method is simple but may be less accurate due to variations in pump nozzles and differences in tank refill levels.
Record Odometer Readings:
Another way to track fuel usage is to record your odometer readings and fuel consumption over a specific period, such as a long trip or weekly usage. Before starting, fill up your tank and record the starting odometer reading. At the end of the trip or period, fill up your tank again and record the number of gallons or liters required to refill, along with the ending odometer reading. This method provides a more accurate estimate of your fuel usage and cost per mile or kilometer.
Maintain Vehicle and Tires:
Improving your vehicle's fuel efficiency can also help you manage fuel usage. Properly inflated tires can reduce fuel consumption by up to 3%, while using the recommended motor oil can improve gas mileage by 1-2%. Regular maintenance, such as keeping the engine tuned and the air filters clean, can also enhance fuel efficiency.

Comparing fuel efficiency
Fuel efficiency is a measure of how well a vehicle uses fuel, or, in other words, how far it can travel using a particular amount of fuel. This is usually measured in miles per gallon (MPG) or kilometres per litre (kmpl).
There are several ways to calculate fuel efficiency, and many free online calculators that can help you do so. One way to calculate MPG is to divide the number of miles travelled by the number of gallons of gas used to refill the tank. This can be done using a smartphone app, or manually. To do it manually, you can reset the trip odometer to zero when you fill up the tank, and then write down the odometer and the amount of gas used to refill the tank each time you need gas. You can then divide the miles travelled by the amount of gas used to refill the tank. This method is most accurate when the tank is filled to the same level each time.
There are several ways to improve the fuel efficiency of your car. One way is to keep your vehicle in good shape. For example, using the manufacturer's recommended grade of motor oil can improve fuel efficiency by 1-2%. Keeping your tires properly inflated can also improve fuel efficiency by up to 3%. Underinflated tires can lower gas mileage by 0.3% per PSI drop.
Another way to improve fuel efficiency is to reduce the weight of your vehicle. The heavier the object, the more energy (and therefore fuel) is required to move it. Removing unnecessary weight can improve fuel efficiency.
Finally, fuel efficiency can be improved by choosing a more efficient vehicle. Four-wheel-drive vehicles tend to be less fuel-efficient than FWD or RWD, as powering all four wheels requires more energy. The latest generation of hybrid vehicles can achieve 50+ MPG, even in large cars.
