Frequently Asked Questions
▶ How do I find my vehicle's real mileage?
Fill the tank full, reset the trip meter, drive normally, then refill. Real mileage = kilometres driven ÷ litres refilled. Real-world mileage is usually 10–20% lower than the brochure figure.
▶ Does this work for bikes and diesel cars?
Yes — it works for any vehicle. Just enter that vehicle's mileage and the applicable fuel price (petrol, diesel or CNG in kg).
▶ How can I reduce my fuel cost?
Maintain steady speed, keep tyres properly inflated, avoid excess idling, service the vehicle on time and remove unnecessary weight. Combined, these can improve mileage by 10–15%.
▶ Can I split the cost between passengers?
Divide the total trip cost by the number of people sharing. For a ₹2,100 trip with 4 people, each person pays ₹525.
