Fuel Loss Report Follow

Overview

The Fuel Loss Report identifies assets that experienced a drop in fuel level between the ignition turning off and the asset's next movement. This report is designed to assist in identifying potential fuel loss incidents.

Important Notes

• IntelliShift only displays assets with a Fuel Type of Gasoline or Diesel. Assets with other fuel types or no designated fuel types within the Asset Profile will not be shown.
• The report uses 10 data points to create a fuel percent average(For Ignition Off & First Movement Fuel Levels) to compensate for fuel fluctuations.

Report Fields

• Asset Name: The unique identifier for the vehicle.
• Fuel Type: The type of fuel used by the vehicle (Defined within the Asset's Profile).
• Ignition Off Time: The time when the vehicle's ignition was turned off.
• Ignition Off Location: The location where the vehicle's ignition was turned off.
• First Movement Time: The time when the vehicle started moving after the ignition was turned back on.
• Ignition Off Fuel %: The calculated average fuel percentage at the time the ignition was turned off.
• First Movement Fuel %: The calculated average fuel percentage when the vehicle started moving.
• Fuel Loss %: The percentage of fuel lost between the ignition off and the first movement fuel level.
• Fuel Loss Gallons: The number of gallons of fuel lost(Requires the Asset's Profile to be set with Fuel Tank Capacity).
• Fuel Loss Dollars: The estimated dollar value of the fuel lost(Requires the Asset's Profile to be set with Fuel Tank Capacity) .

How to Use the Report

1. Access the Fuel Loss Report from the IntelliShift platform Analytics product or Telematics > Reports Product
2. Select to run the Report By Asset or Branch, and make a section.  
3. Select the desired date range for the report.
4. Set the Stop Duration threshold (minimum 30 minutes) if needed.
   1. Default is set to 120 minutes
5. Set the Fuel Loss Percent threshold (minimum 10%, maximum 100%).
   1. Default is set to 15%
6. Click "Next"

The report will display a list of assets with fuel loss information based on the selected criteria.

Understanding the Report

• IntelliShift Methodology: The report leverages 10 data points to calculate average fuel levels at ignition off and first movement.
• Fuel Loss Calculation: The fuel loss percentage is determined by comparing the ignition off fuel percentage to the first movement fuel percentage.
• Fuel Loss Dollars: The estimated dollar value of the fuel loss is calculated based on the fuel price.

Additional Tips

• Use the report to identify trends in fuel loss.
• Investigate assets with high fuel loss percentages for potential issues/theft of fuel.
• Consider using the report in conjunction with other reports for a comprehensive analysis.

How IntelliShift Captures Fuel Data

IntelliShift captures fuel level % from J1939 and OBDII Engine Parameters. J1939 is a standard communication protocol used in heavy-duty vehicles, while OBDII is a standard communication protocol used in most light-duty vehicles.

Fuel Level Fluctuations

Fuel level fluctuations are common in vehicles due to a number of factors, including:

• Fuel Sloshing: Fuel sloshes around in the fuel tank as the vehicle moves, which can cause the fuel level to appear to change.
• Temperature Changes: Fuel expands and contracts with changes in temperature, which can also affect the fuel level.
• Vehicle Dynamics: The way a vehicle is driven can also affect fuel level readings. For example, accelerating and braking can cause the fuel level to fluctuate.
• Fuel Sensor Faults: Are a significant factor that can cause fluctuations in fuel readings. These sensors, which measure the amount of fuel in the tank, can malfunction due to various reasons, including Physical Damage, Electrical Issues, Calibration Errors

IntelliShift compensates for fuel level fluctuations by using a 10-point average to calculate the fuel level at ignition off and first movement. This helps to ensure that the fuel loss percentage is accurate.
