The Mileage Formula
Mileage (km/l) = Distance Travelled (km) ÷ Fuel Consumed (litres)
Getting an Accurate Reading
For the most accurate mileage figure, always measure from one full tank to the next full tank — this ensures you're calculating fuel consumed by actual litres refilled, matched to the exact distance covered on that fuel.
Why Mileage Varies
- Driving style: Aggressive acceleration and braking reduces mileage significantly
- Traffic conditions: Stop-and-go city traffic typically gives lower mileage than steady highway driving
- Vehicle load and tyre pressure: Extra weight and underinflated tyres both reduce fuel efficiency
- AC usage: Running the air conditioner increases engine load and reduces mileage
