What is the tank-to-tank method?

It is the most accurate way to measure mileage. Fill the tank completely, drive, refill it fully again, and divide the distance by the second refill liters.

Why is my real-world mileage lower than the ARAI rating?

ARAI ratings are tested in idealized laboratory conditions. Real-world traffic, braking, road quality, and AC usage reduce mileage by 20-30%.

14.86 km/L

Total Fuel Cost: ₹3,385

Cost per KM

₹6.51/km

Formula

Mileage (km/L) = Distance Traveled / Fuel Liters Cost per KM = Total Fuel Cost / Distance Traveled

Example: 520 km traveled on 35 Liters petrol at ₹96.7/L → Mileage = 14.86 km/L, Cost/KM = ₹6.51/km.

How to use

Fill up your fuel tank fully and note start odometer reading.
On the next refill, note the liters added and end odometer reading.
Provide the refilled fuel liters and distance traveled.
Check fuel mileage and cost-per-km metrics.

Benefits

Simplifies calculation of true highway vs city fuel mileage.
Budget daily commuting or delivery costs.
Check vehicle performance degradation over time.
