In this short

FUEL COST GUIDE Calculate Your Monthly Fuel Bill Use real kilometres, measured mileage and a dated local rate to budget petrol, diesel or CNG.

DELHI EXAMPLE Petrol Costs ₹6.81 Per Km ₹6.81/km That uses ₹102.12 per litre and an illustrative 15 km/l efficiency as of October 2026.
COMPARE CAREFULLY Fuel Units Are Different ₹86.98/kg Delhi CNG is priced per kilogram, so compare it using km/kg rather than km/l.
PRICE IMPACT A Rate Change Adds Up ₹333/month A ₹5/litre petrol increase adds about ₹333 to a 1,000 km month at 15 km/l.
