Fuel Drain Incorrectly Considered as Consumption

Fuel consumption figures may appear incorrect when a fuel drain event is calculated as fuel consumption instead of being identified separately as a drain event.

This can cause the reported fuel consumption to be higher than the actual fuel used by the vehicle and may result in discrepancies in fuel reports and graphs.

Example Questions

• • Why is fuel consumption higher than expected?
  • Why is a fuel drain being included in fuel consumption?
  • Why does the fuel report show incorrect consumption?
  • Why is fuel drained from the tank not appearing as a separate drain event?
  • How can I verify whether fuel drain is being calculated as consumption?

Symptoms / How to Identify

• Fuel consumption is higher than the expected vehicle usage.
• A noticeable fuel level decrease is included in consumption.
• The fuel graph shows a sudden decrease that appears to be treated as consumption.
• Fuel drain and normal fuel consumption are not being distinguished correctly in the report.

Information Required Before Troubleshooting

• Vehicle/Object name.
• Date and time of the reported discrepancy.
• Fuel Consumption report.
• Fuel Fill/Drain report.
• Fuel graph for the affected period.
• Fuel calibration settings.
• Raw fuel data, if required.

Troubleshooting Steps

1. Review the Fuel Consumption Report for the affected period.
2. Compare the consumption figures with the Fuel Fill/Drain Report.
3. Check the fuel graph for sudden decreases in fuel level.
4. Identify whether the decrease represents normal fuel consumption or a fuel drain event.
5. Verify the fuel calibration and Fill/Drain configuration.
6. Check whether the drain event is being detected separately from consumption.
7. If a drain is being included in consumption, review the applicable fuel configuration and calibration settings.
8. After making the required changes, regenerate the relevant fuel reports and compare the results.

Possible Cause

• Fuel drain is being considered as normal fuel consumption.
• Fuel Fill/Drain detection or calibration is not configured appropriately.
• A sudden fuel-level decrease is not being identified as a separate drain event.

Resolution / Action

Verify the fuel graph and reports to determine whether the fuel decrease is a drain event or actual consumption.

If the drain is being calculated as consumption, review and correct the relevant fuel calibration and Fill/Drain configuration so that fuel drain is identified separately from normal consumption.

After making the required changes, regenerate the fuel reports and verify that fuel consumption and fuel drain are reported separately and accurately
