Frequently asked questions

How do I find my car’s fuel economy?+

Check the manufacturer figure or divide distance travelled by fuel used since the last fill. Real-world economy is usually a little worse than the sticker figure.

What is L/100km versus mpg?+

L/100km measures litres used per 100 kilometres (lower is better); mpg measures miles travelled per gallon (higher is better). The tool converts automatically.

Does it include tolls or parking?+

No. It estimates fuel only. Add other costs separately.

Is my data saved?+
