Rajdeep E20 Petrol Debate: Experts Weigh In On Mileage, Engine Safety, Experts Explain | India Today

India's E20 ethanol-blended petrol program, which achieved its 2025 target five years ahead of schedule, presents a complex trade-off between environmental benefits and practical challenges. While ethanol reduces crude oil imports, lowers carbon dioxide emissions, and supports farmers' economies, experts acknowledge genuine fuel efficiency losses of 3.8-12% and potential corrosion issues in older vehicles. The government cites extensive vehicle trials covering 40,000 km in cars and 20,000 km in two-wheelers, demonstrating only minor mileage changes with no adverse engine impact. However, the debate highlights the importance of consumer choice, proper vehicle maintenance, and balanced policy implementation to ensure energy security without compromising consumer confidence.
