Note the odometer
Read it at the pump, before you drive away and forget.
A fuel tracker for every fill-up
Fuel economy is a feeling until you write down the liters, the money, and the kilometers. RPMBase is a car fuel tracker: each fill-up is a row, and the mileage comes from those rows.
Free to start. Fill-ups live on your phone. This website does not save a fuel log.

What a fill-up stores
Liters or gallons
The volume you bought, in the unit on the pump. Partial tanks still belong in the log.
What you paid
The amount on the receipt, in your currency. Fuel cost is then a history, not a single expensive week.
The odometer at the pump
Read it before you drive away. Distance without fuel, or fuel without distance, is a weak row.
Economy from your rows
Liters per 100 km or mpg come from fill-ups you actually kept. A trip computer that resets is not the log.
Separate from insurance and tax
Those bills sit on the expense tracker. The fuel log is only the pump.
A one-off calculator when you need it
The fuel economy tool on this site does the arithmetic once. The tracker is for the pattern across months.
A fill-up takes four facts
What the fuel log is for
You want liters per 100 km, or mpg
Use the fuel economy tool for a one-off sum. Use the log when you want the pattern across months.
You share the car
Each fill-up names the car, so two drivers do not mix receipts.
You are watching what the car costs
Fuel is usually the largest running cost. It should be visible next to everything else, not buried in a bank statement.
One tank does not tell you the month
The trip computer resets. A single full-tank calculation ignores the three partial fill-ups you did not write down. Receipts show the money and not always the odometer.
A fuel mileage tracker needs the distance and the fuel together. Without both, cost per kilometer is a guess, and so is the difference between summer and winter.
When you fill up, you record how much fuel you bought, what you paid, and the kilometers on the car. Do that most of the time and the history becomes a fuel mileage tracker you can trust more than memory.
Fuel stays separate from insurance, tax, and repairs. Those belong on the expense tracker. The fuel log is only the pump.
One full tank is a weak answer. Three partial fill-ups you did not write down will skew the month. A fuel mileage tracker needs the distance and the fuel together, most of the time, not perfectly every time.
Sharing a car is where receipts get mixed. Each fill-up names the vehicle. Two drivers can see the pump history without forwarding photos of slips.
This website will not track your location or your trips. RPMBase is a fuel tracker for fill-ups you record. Get App is how you wait for the phone log.
Questions
Do I have to fill the tank every time?ShowHide
No. Log the fuel you bought and the odometer. Full-tank habits make economy easier to read, but partial fill-ups still belong in the tracker.
Is this a fuel mileage tracker and a navigation app?ShowHide
It is a fuel mileage tracker for fill-ups you record. It does not track your trips or your location.
Where do insurance and parking go?ShowHide
On the car expense tracker. Keeping them off the fuel log is how you can see fuel on its own and ownership cost as a whole.
