Frequently Asked Questions
How to calculate fuel cost per km?
Fuel cost per km = Fuel price per litre ÷ Vehicle mileage (km/litre). For example, if petrol is ₹105/litre and your car gives 15 km/litre, your cost per km is ₹105 ÷ 15 = ₹7 per km.
What is the average mileage of cars in India?
Average real-world mileage in India: Petrol hatchbacks 14-18 km/l, petrol sedans 11-15 km/l, diesel cars 16-22 km/l, petrol SUVs 8-12 km/l. CNG vehicles typically give 20-30 km/kg. Actual mileage depends on driving conditions, traffic, and AC usage.
Is CNG cheaper than petrol for daily commute?
Yes, CNG running cost is typically 40-60% lower than petrol. For example, if petrol costs ₹7/km and CNG costs ₹3/km, you save ₹4 per km. For a 30 km daily commute, that’s ₹120/day or ₹3,600/month savings. Use our CNG vs Petrol Calculator for detailed comparison.
