This issue is caused by fuel movement in the tank. If in object setting “Detect stops using” is set to GPS when the object stops fuel can move by inertia inside the gas tank causing incorrect Fuel level readings which may cause wrong fuel level data.
To fix this issue you need in Object settings->Accuracy tab set "Detect stops using" to ACC. This will provide you more accurate fuel consumption data.
