Frequently asked questions
Should I include the driver in the passenger count?
Yes, if you want the cost split equally among everyone in the car. If the passengers are covering the driver's fuel as a thank-you, simply enter the number of passengers excluding the driver.
How accurate is the fuel cost estimation?
It provides a solid baseline, but real-world consumption varies based on traffic, AC usage, and how heavily loaded the vehicle is with passengers and luggage.
How can I reduce my fuel costs on a road trip?
Maintain proper tire pressure, drive at a consistent speed, and remove unnecessary roof racks to improve aerodynamics.
