Frequently asked questions
Does this include tolls or parking?
No, this covers fuel only; add tolls, parking and accommodation separately for a full trip budget.
What fuel economy figure should I use?
Use your own recent L/100km figure from the Fuel Economy calculator for the most accurate trip estimate, since real-world use often differs from the sticker figure.
Can I use this for a return trip?
Yes, enter the total return distance, or calculate one way and double the result.
