The Supreme Court is set to tackle a contentious issue on September 1, 2025, as it hears a public interest litigation (PIL) challenging the nationwide rollout of 20% Ethanol Blended Petrol (EBP-20), sparking fears that millions of Indian motorists are being forced to use fuel incompatible with their vehicles. Filed by advocate Akshay Malhotra, the plea, slated before a bench led by Chief Justice B.R. Gavai, demands urgent action from the Ministry of Petroleum and Natural Gas to address the growing crisis affecting car and two-wheeler owners across the country.

The PIL alleges that vehicles, particularly those manufactured before 2023 and even some newer BS-VI models, are not designed to handle the high ethanol content, leading to severe mechanical issues. Petitioners are calling for the availability of ethanol-free petrol at all fuel stations, mandatory labeling of ethanol levels on pumps, and clear notifications to consumers about vehicle compatibility during refueling. The plea also seeks a nationwide study to assess the impact of EBP-20 on engine degradation, fuel efficiency losses, and mounting repair costs, which have left motorists grappling with unexpected expenses.

Reports of engine corrosion, reduced mileage, and rejected insurance claims due to ethanol-related damage have fueled public outrage. The petition highlights a stark contrast with global practices, noting that countries like the US and EU offer ethanol-free options and transparent labeling, empowering consumers with choice. In India, however, the lack of disclosure about fuel composition at dispensing units has left drivers vulnerable, with no alternative but to purchase potentially harmful blends.

The ethanol push, part of India’s renewable energy initiative, aims to reduce oil imports and carbon emissions, but critics argue it overlooks vehicle compatibility and consumer rights. The PIL warns that without intervention, the policy could lead to widespread vehicle damage, economic loss for millions, and a public health risk from faulty engines. As the court prepares to deliberate, stakeholders from the automotive industry and environmental groups are watching closely, hoping for a ruling that balances sustainability goals with practical safeguards for India’s vast motorist population.
