Fuel Monitoring: How to monitor, analyze and optimize fuel consumption?

In a context where fuel costs represent between 30 and 40% Of the total operating expenses of a car fleet, the question of consumption is becoming crucial. Add to this another challenge: the fight against fuel theft, a widespread phenomenon that is difficult to assess and correct without tools. The Fuel Monitoring solution comes into play!

What is Fuel Monitoring?

Fuel Monitoring is an intelligent fuel monitoring technology. It makes it possible to monitor the fuel consumption of a vehicle in real time. This device is based on the fuel probe and software platform that collect, analyze, and compare fuel data. The objective of this intelligence is to optimize consumption, reduce costs and prevent anomalies or thefts.

OPTIMUM's Fuel Monitoring solution

Optimum offers a complete solution for monitoring the fuel of your vehicle fleet. Integrated into the Optimum platform, the Fuel Monitoring solution allows accurate fuel monitoring for all types of vehicles (light to heavy vehicles). Here are the main features of this system:

1 — Real-time fuel monitoring

Each type of vehicle is equipped with a suitable device:

  • For light vehicles: the CAN (Controller Area Network) telematics unit or the manufacturer's unit is connected to the vehicle's electronic system and returns dashboard data, including the fuel level.
  • For heavy vehicles: a probe placed in the tank makes it possible to measure the fuel level.

These technologies offer a real-time vision of the fuel level of each vehicle in the fleet.

2 — Anomaly detection and alerts

The Optimum solution not only reports data, it can act by sending alerts automatically during 3 events:

  • Sudden drop in fuel level when stationary: the hypothesis of theft is plausible
  • Critical fuel level
  • Refilling the tank

The Optimum platform goes further, it crosses the filling data with the fuel bills recorded in the system. If a discrepancy occurs between the invoiced volume and the volume measured in the tank, an alert is sent to the manager. This makes it possible to detect and prove fuel theft at the pump.

3 — Analysis reports

The Optimum platform generates automated and customizable reports, here are the different types of reports related to fuel:

  • The consumption report: it highlights consumption and identifies the driving habits of the most energy-consuming users and vehicles.
  • The standstill consumption report: it highlights the consumption when the vehicle is stopped with the engine running.
  • The billing discrepancy report: it makes it possible to identify the differences between the invoiced fuel and the fuel actually put into the tank.
  • The alert report: it is a summary of the various alerts related to fuel.

OPTIMUM Fuel Monitoring, a concrete response to challenges in the field

Fuel theft represents a significant financial loss for transport companies in France. According to the National Federation of Road Transporters (FNTR), more than 20 million liters of diesel are stolen each year, i.e. an estimated damage of around 20.6 million euros per year (2023). This situation has a direct impact on the profitability of businesses.

In conclusion and in the face of this observation,

OPTIMUM Fuel Monitoring offers an effective solution to prevent and detect fuel theft. By providing transparency and traceability in fuel management, it becomes possible to secure supplies, empower drivers and take corrective measures if necessary.
