How fuel cost is calculated

Fuel needed = Distance ÷ Mileage, and Cost = Fuel needed × Fuel price. For example, a 700 km round trip in a car that gives 15 km/l, with petrol at ₹103, needs about 46.7 litres and costs about ₹4,807.

Tips to improve mileage

  • Keep tyres at the recommended pressure — under-inflated tyres waste fuel.
  • Drive smoothly at steady speeds; avoid hard braking and sudden acceleration.
  • On highways, 60–80 km/h is usually the most fuel-efficient range.
  • Remove unnecessary weight and roof carriers.
  • Service your vehicle on time and switch off the engine at long signals.

Real-world mileage is often 10–20% lower than the company-claimed figure, especially in city traffic. Fuel prices differ between cities — enter your local price.
