Frequently asked questions
How do I find my vehicle's mileage?
Fill the tank, reset the trip meter, drive normally, then refill and divide the kilometres driven by the litres used. Your dashboard's average consumption figure is a good estimate too.
Why is cost per km useful?
It lets you compare vehicles and trips at a glance. A car that costs $0.10 per km is half as expensive to run as one that costs $0.20 per km over the same distance.
Does this include tolls and other costs?
No — this is fuel only. Tolls, parking, wear and tear and depreciation are separate costs of a trip.
How can I cut my fuel cost?
Drive smoothly at a steady speed, keep tyres at the right pressure, remove roof racks and excess weight, and avoid idling. Aggressive acceleration and high speeds raise consumption sharply. Use it as a fuel cost calculator free — no signup, nothing to install.
