The Government of India has indicated that any increase in ethanol blending in petrol beyond the current 20% (E20) will be implemented gradually, following testing to ensure vehicle compatibility.

Road Transport and Highways Minister Nitin Gadkari stated on 12th September that any increase in ethanol blending beyond 20% will only be carried out after all necessary testing has been completed to confirm it does not adversely affect vehicles.

He explained: "India already has standards in place. Based on these, ARAI will conduct all the necessary tests. If the tests are successful, ARAI will submit its proposal to the Petroleum Ministry. Once the ministry is satisfied, it will recommend it to the Cabinet and the Prime Minister for approval. Only then will a final decision be taken. There is no confusion about the process."

Gadkari made these remarks during a discussion with media sources at the 65th Annual Session of the Automotive Component Manufacturers Association of India (ACMA).

As India progresses with its ethanol-blending programme, the transition to E20 fuel has raised concerns among consumers, particularly owners of older vehicles. A primary issue is that potential damage or performance problems resulting from E20 use may not be covered under manufacturer warranties, leaving vehicle owners responsible for repair costs.

The Society of Indian Automobile Manufacturers, ARAI, and Oil Marketing Companies (OMCs) have stated that E20 can be safely used by consumers. They have also noted that the shift supports the economy, benefits farmers, and contributes to energy independence.

Gadkari rejected claims that E20 fuel reduces vehicle life or causes significant drops in mileage, describing such allegations as "a paid propaganda by some lobbies." He stated that the social media backlash was politically motivated rather than technically substantiated and characterised the claims as part of a "political campaign" directed against him.

On 11th September, Gadkari noted that automobile companies had initially raised concerns regarding the compatibility of E20 with existing vehicle engines. "The concerned auto companies, ARAI and others submitted their findings. The Supreme Court also took their stand," he further added.

To date, no government decision has been taken regarding an increase in ethanol blending beyond 20%.
