Fuel management software is a tool that combines real-time measurement of each vehicle’s fuel consumption, integration of fuel card transactions, automatic detection of anomalies, and cost reporting in an exportable dashboard. It allows a fleet manager to determine the actual fuel cost on a per-vehicle basis, rather than relying on fleet averages derived from consolidated invoices. Fleeti covers the entire process, from the sensor installed on the vehicle all the way to data export to the finance department and ESG reporting.

Fleeti collects engine data via the CAN bus or the vehicle’s OBD port for newer fleet vehicles, providing access to real-time fuel consumption, engine RPM, speed, and idle time. For construction equipment, older heavy-duty trucks, and vehicles without an FMS interface, a capacitive sensor is installed directly in the fuel tank: it measures the fuel level independently of the original ECU. Both modes can coexist within the same fleet on a single platform.

The CAN bus measures the engine fuel consumption calculated by the vehicle's ECU: it provides very accurate real-time readings, but only works on newer vehicles equipped with the FMS protocol. The capacitive sensor directly measures the fuel level in the tank: it is less accurate for real-time fuel consumption but more reliable for detecting a sudden drop (fuel siphoning), and it works on all vehicles, regardless of their model year or engine type. Most fleet management software on the market (Geotab, Webfleet, Quartix) relies solely on the CAN bus, which leaves construction equipment and older fleets out of coverage. Fleeti systematically combines both approaches into a single platform to cover heterogeneous fleets, particularly construction equipment running on GNR and older heavy-duty trucks.

Three combined mechanisms make it possible to detect fuel theft. First, an abnormal drop in the tank level between two trips, measured by the capacitive sensor: siphoning is immediately flagged. Second, refueling outside authorized zones or outside working hours, cross-referenced with the vehicle’s GPS location: fuel card fraud becomes traceable. Third, a transaction volume that is inconsistent with the tank’s technical capacity at the time of refueling: the excess volume is flagged as an anomaly. Like Optimum or SuiviDeFlotte, Fleeti detects these anomalies in real time. What sets Fleeti apart is that it systematically archives time-stamped evidence (date, GPS location, fuel level before and after, associated transaction) to build a case that can be presented to an insurer or law enforcement, without any manual intervention by the manager.

Fleeti automatically cross-references each fuel card transaction with the GPS location of the vehicle to which the card is linked. A transaction made while the vehicle is elsewhere (e.g., the card is used by a third party or fuel is purchased for a personal vehicle) triggers an alert. Similarly, refueling with a volume of fuel exceeding the tank’s remaining capacity at the time of refueling, or refueling at a gas station located far from the vehicle’s usual route, is flagged as suspicious. You have access to a complete history for each driver and each card.

Typical savings observed after deploying fuel management software range from 15% to 25% of the annual fuel bill. Several factors contribute to these savings: identifying vehicles with high fuel consumption, providing targeted training for drivers with costly driving habits, detecting phantom refueling and fuel card fraud, and eliminating excessive idling time. For a fleet of 100 vehicles that consume 8 liters per 100 kilometers and travel 25,000 kilometers per year, a 15% savings translates to tens of thousands of euros in fuel saved annually. The return on investment for fuel management software is typically achieved in less than twelve months.

Yes. Construction equipment powered by non-road diesel is one of the most common use cases on the Fleeti platform. The measurement system relies on a capacitive sensor installed directly in the fuel tank, independent of the machine’s computer, which allows for measuring fuel levels and detecting theft even on older excavators, loaders, dump trucks, and compactors. Monitoring is expressed in terms of consumption per engine hour rather than liters per 100 kilometers, which is more relevant for construction equipment. Engine hours are also tracked, which helps determine when to replace parts and schedule preventive maintenance.

Yes. Fleeti integrates with the major fuel cards used by commercial fleets. Integration is achieved through the automatic retrieval of transaction records, without any action required from your provider. You keep your current contract; you simply add the management and anomaly detection layer. If your provider isn’t yet integrated, the Fleeti team can develop the connector as part of the deployment.

Fuel management for a mixed fleet relies on three levels of fuel consumption monitoring. First, measurement: CAN bus for newer vehicles, capacitive sensors for older vehicles and heavy-duty trucks, and self-reporting and fuel cards for service sector fleets without onboard telematics. Next comes monitoring: liters per 100 kilometers, liters per hour of engine operation, and cost per kilometer, continuously compared to the fleet median. Finally, alerts: any excessive fuel consumption, excessive idling, or unusual refueling is reported in real time. Fleeti centralizes fuel management for the entire fleet on a single platform, regardless of the vehicle’s powertrain (gasoline, diesel, GNR, hybrid, electric).
