AAP convenor Arvind Kejriwal on Friday, 3 July 2026, announced he will write a formal letter to Prime Minister Narendra Modi over public grievances linked to E20 petrol, the government-mandated fuel blended with 20% ethanol, saying the policy is being forcibly imposed on citizens whose vehicles are suffering as a result.

Posting in Hindi on X, Kejriwal wrote: 'मोदी सरकार के लिए पूरा देश एक experiment lab है' ('For the Modi government, the entire country is an experiment lab'). He alleged that ethanol blending is causing vehicles to stall, damaging engine parts, and reducing mileage — and that public anger over the issue is running high. He invited followers to DM or comment with suggestions on what the letter should include.

Context

The E20 programme mandates a blend of 20% ethanol in petrol at fuel stations across India. The central government, under the Ministry of Petroleum and Natural Gas, has been rolling out progressively higher ethanol blends since the early 2000s, with the pace accelerating sharply after 2014. The National Policy on Biofuels 2018 originally set the 20% blending target for 2030; in June 2021, the government advanced that deadline to 2025 and released a phased roadmap.

The programme is designed to reduce India's dependence on crude oil imports and provide assured offtake for sugarcane farmers, making it a dual-purpose energy and agricultural policy. Oil marketing companies have been central to its implementation, coordinating supply chains for ethanol procurement and blending.

Policy Backdrop

Ethanol is derived primarily from sugarcane molasses and, increasingly, from damaged food grains. Higher ethanol content in fuel has long been associated with concerns about material compatibility — rubber seals, fuel-line components, and carburettors in older vehicles were not designed for high-ethanol blends. The automobile sector has raised these compatibility questions periodically at each phase of the programme's expansion.

Newer vehicles sold after a certain model year are typically certified as E20-compatible by manufacturers, but a large share of India's vehicle fleet on the road predates those standards. Consumer complaints about reduced mileage under higher ethanol blends have also appeared in earlier phases, as ethanol carries lower energy density than pure petrol. NationPress notes that the specific claims of widespread breakdowns and mileage loss cited by Kejriwal have not been independently verified.

Stakeholders and Impact

The most directly affected group is India's vast base of private vehicle owners — two-wheeler and four-wheeler users alike — many of whom operate older models not rated for E20. If Kejriwal's letter triggers a formal parliamentary or ministerial response, oil marketing companies and automakers could face pressure to clarify warranty and compatibility positions publicly.

Sugarcane farmers and ethanol producers, on the other hand, have benefited from the programme's assured demand. Any rollback or slowdown in the blending mandate would affect that supply chain. The Ministry of Petroleum and Natural Gas and the auto industry's submissions to it on E20 compatibility standards are expected to be closely watched, particularly during the ongoing monsoon parliamentary session.

What's Next

Kejriwal's announcement is explicitly participatory: he has asked citizens to contribute to the letter's content via direct messages and comments, a tactic that doubles as public mobilisation. The actual letter to Prime Minister Modi is expected to follow once he consolidates the feedback.

Whether the government responds formally — through the petroleum ministry or the Prime Minister's Office — will determine how far the issue travels in the policy arena. With the monsoon session of Parliament under way, opposition parties are likely to watch for an opening to raise vehicle-compatibility and consumer-protection questions on the floor of the House.
