Fuel offset
Fuel offset defines how much the daily change in fuel prices may be (the maximum price fluctuation).
The fuel offset field is located in the task’s advanced settings tab.

It allows entering only numeric values (matching the defined price format), or leaving the field empty. (The system does not require the user to set an offset. If the user leaves the field empty, the system will enter the value “0” in it.)
Visibility of the Price offset field:

With the CanDisplayFuelsDashboard permission enabled, the Price format and Price offset fields are visible on the task edit screen
After the CanDisplayFuelsDashboard permission is disabled, both fields disappear from the task edit screen; you can open the task edit and save both newly created and edited tasks
