Fuel Fill-Up Diary
Log fuel purchases and track fuel consumption across repeated fill-ups. Handle partial tanks, missed entries and metric or imperial units.
How can I track real fuel use from fill-ups?
Record fuel quantity and the odometer each time you refuel. Start with a full tank, then continue logging partial and full fills. At the next full tank, the tool divides fuel added since the baseline by the distance travelled. Mark missed fill-ups to reset the baseline. Weighted averages use only complete measured intervals.
