Mumbai.The Centre has strongly defended its nationwide E20 ethanol-blended petrol programme amid mounting criticism from vehicle owners and questions raised over its long-term impact on engines. Seeking to dispel growing apprehensions, government officials and leading automobile manufacturers on Saturday asserted that the transition to E20 fuel has followed years of scientific research, extensive testing and phased implementation rather than being a hurried experiment. They maintained that no credible evidence has emerged to show that E20 petrol damages vehicle engines, even as the debate has intensified after recent observations made during proceedings in the Supreme Court.

Scientific Testing Backs E20 Fuel Rollout

Addressing a joint press conference in New Delhi, former Engineers India Limited CMD Vartika Shukla said ethanol blending has been introduced through a structured and evidence-based process involving government agencies, automobile manufacturers and technical institutions. She noted that India has steadily increased ethanol blending in petrol from around 1.5 per cent in 2013-14 to 20 per cent by December 2025, achieving the national target five years ahead of schedule. According to her, agencies such as the Automotive Research Association of India (ARAI) and the Society of Indian Automobile Manufacturers (SIAM) have carried out detailed evaluations before the rollout. She said the programme conforms to global best practices and complies fully with BS-VI emission standards.

Industry Leaders Reject Engine Damage Claims

Representatives of Maruti Suzuki, Toyota Kirloskar Motor, Hyundai Motor India, TVS Motor, Hero MotoCorp and Bajaj Auto echoed the government's position, saying extensive testing has not revealed any major concerns over engine safety or performance. Maruti Suzuki's Rahul Bharti acknowledged that most apprehensions relate to petrol vehicles manufactured before 2023, but said the company's studies have not found anything alarming about the use of E20 fuel.

Key takeaways from the industry:

• No scientific evidence has linked E20 petrol to engine damage.
• Vehicle performance remains within expected standards.
• A marginal drop in fuel efficiency may occur.
• Modern E20-compatible vehicles have shown normal performance in testing.

Energy Security Drives Ethanol Push

The government said the programme is aimed at reducing India's dependence on imported crude oil while lowering carbon emissions and increasing farmers' income through higher ethanol production. Former Indian Oil Corporation Chairman B Ashok said scientific studies have not established that E20 fuel causes significant engine wear or serious mileage loss. He argued that many concerns circulating on social media are not supported by scientific evidence and often exaggerate isolated experiences. Toyota Kirloskar's Vikram Gulati also pointed out that ethanol-based fuels are used even in high-performance Formula One racing, underscoring their technical reliability.

Supreme Court Remarks Trigger Fresh Debate

The government's defence comes just days after submissions made during Supreme Court proceedings triggered confusion over the E20 programme. Reports quoting the hearing suggested the government had described the initiative as an ongoing experiment whose complete impact would become clear only next year. The subsequent clarification, however, stressed that the court proceedings related to ethanol allocation issues and should not be interpreted as questioning the scientific foundation of the E20 fuel programme. Even so, the remarks have fuelled fresh public debate over the compatibility of older petrol vehicles with higher ethanol blends.

Questions Persist Despite Official Assurance

Despite repeated assurances from the government and automobile manufacturers, concerns continue among owners of older petrol vehicles, many of whom claim that E20 petrol has reduced mileage, increased maintenance costs and affected engine components. Officials, however, insist that the programme is based on rigorous scientific assessment and aligns with international practices adopted by several countries.

What the government maintains:

• E20 petrol does not damage vehicle engines.
• The rollout followed years of scientific evaluation.
• Top automotive agencies validated the fuel before implementation.
• The programme strengthens energy security and reduces emissions.
• Concerns over older vehicles will continue to be monitored as adoption expands across the country.
