Fuelbook
What core data does Fuelbook require to calculate my fuel economy?
Fuelbook needs the four key pieces of information from each fill-up: odometer reading, gallons pumped, total cost, and price per gallon. From these, it automatically calculates your tank MPG, overall average, and cost per mile.
Can I export my fuel logs from Fuelbook to use in a spreadsheet?
Yes, you can export all your logs to a CSV file directly from the settings menu. This is a great feature for data lovers who want to analyze their fuel history in Excel or Google Sheets.
My MPG seems off after the first few fill-ups. Is there a way to see a more reliable trend?
Fuelbook automatically shows a rolling 3-tank average alongside your lifetime average after you've logged a few fill-ups. This helps you spot real trends and smooth out the impact of a single anomalous tank, like a bad batch of gas or a heavy-traffic week.
I accidentally entered the wrong odometer reading. Can I edit or delete a past fill-up entry?
Yes, you can edit or delete any past entry by tapping on it in your log. Just correct the odometer, gallons, or cost, and Fuelbook will recalculate all your averages and charts automatically.
How does Fuelbook compare to other mileage apps like Fuelly or GasBuddy?
Unlike apps that try to be social networks or ask for unnecessary permissions, Fuelbook is a focused, utilitarian tool. It strips away all the fluff and gives you exactly what you need: quick fill-up logging, accurate MPG calculations, and a clean CSV export, without trying to connect you to other drivers.
