Fuel Efficiency Explained: How to Calculate It and Its Benefits!
Fuel efficiency is a crucial aspect of business‑vehicle management. By improving fuel efficiency, not only will it save fuel consumption and enhance the operation of business vehicles, but it will also impact other areas. So, what exactly is fuel efficiency?
Definition of fuel efficiency
Fuel efficiency is a way to maximise fuel use to save money. Fuel efficiency is calculated by comparing vehicle distance traveled per liter. The further the distance traveled per liter of fuel, the better your fuel efficiency will be.
To improve fuel efficiency, here are several influencing factors that you need to address:
-
Vehicle size and load
-
Fuel quality
-
Tyre condition
-
Road conditions and traffic congestion
-
Driver behaviour
-
Poor maintenance

Why do we need to calculate fuel efficiency?
Monitoring fuel efficiency has various benefits for your business vehicles, including:
-
Daily cost efficiency
When calculating fuel efficiency, we can compare changes in fuel consumption and identify the source of the issue. We can then find solutions to maximise fuel usage, which overall helps reduce the daily operating costs of business vehicles. -
Positive environmental impact
Fuel efficiency contributes to environmental protection efforts by directly reducing carbon emissions. As a result, fuel efficiency helps support a greener and more sustainable environment worldwide. -
Better vehicle maintenance
After implementing vehicle efficiency measures, you will gain a clear picture of vehicle performance. By understanding performance and vehicle condition, you can schedule maintenance in the future to continuously improve or maintain your vehicle’s performance. -
Improved driving safety
With a better understanding of fuel efficiency and consumption, you can focus on improving safe and responsible driving behaviour. Reducing speed and maintaining a safe following distance are some key aspects that help improve road safety while driving.

How can you measure the fuel efficiency of business vehicles?
The only way to know the fuel efficiency level of a business vehicle is to calculate the amount of fuel consumption in the following steps:
-
Fill the fuel tank completely.
-
Collect data
Fuel consumption is a clear indicator of how efficiently fuel is being used by your business vehicles. Manually, this can be done by checking fuel receipts and tracking vehicle mileage for each trip (odometer readings). Want to collect data faster? Use Cartrack’s fleet management system, which automatically calculates fuel refills and business fleet mileage. -
Calculate fuel efficiency
After collecting the data, use it to calculate the average fuel consumption per 100 km. How? Divide the amount of fuel used by the distance travelled, then multiply by 100. -
Compare fuel efficiency results
Use the result you obtained to compare it against industry fuel efficiency standards.
As an example, if a vehicle travels 300 kilometres using 25 litres of fuel, then fuel consumption can be calculated as follows:
Fuel consumption = 25 liters/300 km = 12 km/liter
Calculating the amount of fuel consumption of business vehicles can increase the level of fuel efficiency and improve vehicle operation.
What is a good litres per 100 km?
If your vehicle is in good condition, any number of liters per 100 km indicates good fuel efficiency. However, other factors such as vehicle type, weight and size, and driving conditions can affect fuel consumption.
