Government Defends E20 Petrol, Says It’s Safe and Backed by Research

Government authorities have issued a firm statement in support of E20 petrol, addressing rising concerns from vehicle owners who fear damage to their engines and a drop in fuel efficiency. With the country now transitioning to 20% ethanol-blended petrol across fuel stations, the Ministry of Petroleum and Natural Gas has made it clear that the blend is both safe for use and scientifically backed.

In its clarification, the ministry said that concerns circulating on social media and in sections of the press were “largely unfounded.” It cited multiple long-term studies and testing conducted by reputable institutions to assure the public that E20 has undergone comprehensive evaluation before its rollout.

According to government sources, both older and newer vehicles were tested with E20 petrol for over 100,000 km under various conditions. The results showed no meaningful decline in power or torque, and more importantly, no engine damage. Testing intervals of every 10,000 km also revealed stable emissions and mechanical durability, proving that E20 is suitable for the Indian market.

Government Explains E20 Impact on Mileage, Engine Life and Environment

One of the most common concerns has been around fuel efficiency. Ethanol contains less energy than regular petrol, which naturally results in a small reduction in mileage. However, the ministry clarified that this drop is minimal only around 1–2% for cars that are already designed for E10 and calibrated for E20. Even for older vehicles, the drop is manageable, ranging between 3–6%.

To make the transition smoother, automakers have already started using E20-compatible components in new vehicles since April 2023, ensuring fuel systems are protected against wear or corrosion. The Society of Indian Automobile Manufacturers (SIAM) also confirmed that manufacturers are well-aligned with the E20 rollout roadmap.

In terms of vehicle maintenance, the government admitted that some older rubber parts or gaskets in legacy vehicles may need replacement after extended use with E20. However, this is neither expensive nor unusual it is a part of standard upkeep and doesn’t involve any critical damage to the engine.

Corrosion concerns were also addressed. The fuel formulation already includes corrosion inhibitors and adheres to BIS and Automotive Industry Standards, ensuring long-term safety and material compatibility.

Government Pushes Ahead with Ethanol Fuel Plan Despite Doubts

The Government’s ethanol policy is not just about fuel it is a multi-layered strategy for environmental, economic, and rural development goals. Ethanol, being plant-based, helps reduce carbon emissions significantly. According to NITI Aayog, sugarcane-based ethanol lowers lifecycle emissions by around 65%, while ethanol derived from maize reduces emissions by up to 50%.

Ethanol production is now happening using a wide variety of raw materials, including surplus grains, damaged rice, and agricultural residues. This supports second-generation (2G) biofuel technology and gives Indian farmers an additional income stream through ethanol supply contracts.

Since the blending programme began, India has saved over ₹1.40 lakh crore in foreign exchange by reducing petrol imports. At the same time, over ₹1.20 lakh crore has been paid directly to farmers as part of ethanol procurement, showing how the policy is helping stimulate rural economies while pushing for energy self-reliance.

Planned and Phased Not Sudden

The Government clarified that the E20 rollout wasn’t a hasty decision. The Roadmap for Ethanol Blending in India 2020–25 was released in public domain back in 2021, and since then, fuel companies, automakers, and regulatory bodies have worked in coordination to ensure a gradual shift.

E20’s higher octane rating (around 108.5 compared to 84.4 for petrol) supports better combustion in modern engines. Ethanol’s properties also help reduce intake air temperature, improving engine efficiency in compatible vehicles.

Government representatives emphasised that E20 is a step toward the future of clean energy combining scientific research, environmental responsibility, and rural economic empowerment.

Conclusion

The Government has firmly backed E20 petrol, stating that it is safe, reliable, and an essential part of India’s energy transition. While minor changes in mileage may occur, long-term tests show no major impact on engine life or driving performance. With added benefits to the environment and farmers, the shift to ethanol-blended fuel is set to continue, forming a key pillar in India’s sustainable energy future.
