Frequently Asked Questions

Q: Which unit system should I use?
A: Use Metric (L/100km) if you live in Europe, Asia, Australia, or most other countries. Use Imperial (MPG) if you are in the United States or the United Kingdom.

Q: How accurate is the fuel cost estimate?
A: The estimate is based on your inputs. For best accuracy, use your vehicle's real-world fuel consumption rather than the manufacturer's advertised figure.

Q: Can I calculate fuel cost for a round trip?
A: Yes, simply enter the total round-trip distance. For example, if your round trip is 600 km, enter 600 as the distance to get the total cost both ways.
