It is absolutely necessary to provide an end-of-month odometer reading in order to create a mileage log. Click the Add button to record one.

We recommend that you record your odometer reading at each refueling / charging and at the end of the month, and enter this into the program as well! Enter the value and click Add.

If the data may not be available, you can see in the Details window what odometer readings you have previously recorded.

The end-of-month odometer reading must always be greater than the value specified at the last refueling. You can calculate these with the Calculator assistant.
