2. Petrol vs Diesel Running Cost in 2026 – Which Saves More?

This is one of the most searched car-related questions in India.

Average Fuel Price (2026 Estimate)

• Petrol: ₹100 per litre (approx)
• Diesel: ₹90 per litre (approx)

Example Calculation (10,000 km per year)

Petrol Car (Mileage: 18 km/l)

Fuel required: 10,000 ÷ 18 = 555 litres

Annual Fuel Cost: 555 × ₹100 = ₹55,500

Diesel Car (Mileage: 22 km/l)

Fuel required: 10,000 ÷ 22 = 455 litres

Annual Fuel Cost: 455 × ₹90 = ₹40,950

Difference Per Year:

Diesel saves approx ₹14,000–₹15,000 annually.

But Here’s the Catch
