Ministry of Petroleum and Natural Gas has on 4 August 2025 issued a detailed response to certain concerns raised on the impact of _____ percent Ethanol Blended Petrol on mileage and vehicle life.
Show answer & explanation
Correct answer: A
Explanation
The Ministry of Petroleum and Natural Gas issued a detailed response on August 4, 2025, regarding the impact of 20 percent (E20) ethanol-blended petrol on mileage and vehicle life.
The Indian government aims to phase out E20 fuel (a blend of 20% ethanol and 80% petrol) across the country. The Ministry's clarification in August 2025 was intended to address concerns raised about the potential reduction in engine longevity and fuel efficiency (mileage) in older vehicles.
Key points of E20 fuel and the Ministry's clarification:
Impact on mileage: The Ministry clarified that the reduction in mileage in modern 'ethanol-compliant' engines is negligible (approximately 6-7%), which can be offset by improved engine tuning.
Vehicle Life: The government has assured that most vehicles manufactured after 2008 can tolerate partial mixing, while new vehicles are being built specifically with E20-compliant materials (rubber and plastic parts that are corrosion-resistant).
Environmental Benefits: The use of E20 significantly reduces carbon monoxide and hydrocarbon emissions.
