If the fuel is not filled to the maximum during calibration, the uncalibrated volume will not be included in the fuel-up when the tank is overfilled.

🚨 If the discrepancy is unrealistic, there is reason to believe that the missing fuel has been filled into a canister rather than a tank or stolen.

Technical specifics: CAN fuel-up readings rely on a built-in fuel level sensor of the vehicle, meaning that the sensor does not account for the dead zones that exist in the upper and lower parts of the fuel tank. These dead zones can represent a significant portion of the tank's volume, potentially up to 10%.

Vehicle Age and Condition: Older vehicles may have less precise CAN data due to potential sensor wear and tear. Additionally, the accuracy of CAN data can be affected by the condition of the vehicle's components.

Sensor Calibration: The accuracy of CAN data depends on the calibration and accuracy of the vehicle's sensors. Any discrepancies in sensor readings can lead to variations in reported fuel consumption.

Two-tank system: There is only one fuel level sensor in the main tank. Therefore, if the fuel is being filled in the second tank, you will not see any fuel changes at all until the level in both tanks will come to a balance.
