You can calculate fuel consumption for every trip at any period of time, even if your GPS device is not equipped with the physical fuel sensor.
To do that, you simply need to specify a “Fuel consumption per 100 km (or miles)” parameter in the vehicle profile.
After you specify this parameter, fuel consumption readings will be available in:
1. Trip report – in a column called “Fuel consumption by norm”, next to every trip and also in the summary over a period.
