Enter a value in one of the fields.
Fuel consumption, (driving) distance, fuel amount (and cost if the price is entered) can be calculated directly by entering a number in the field that you have a value for. When values have been entered in two of the entities mentioned above, the third can be derived. E.g. enter a fuel amount and a distance, hit the "Derive" button in the fuel consumption area to calculate its value based on the values entered.
Microsoft Internet Explorer users may have to click outside of the input fields to get results.
