Protesters in India are demanding a rollback of the nationwide E20 ethanol-blending mandate after the government hinted at a move toward E25 [1, 2].

The dispute centers on whether the shift to biofuels actually benefits the consumer or primarily serves state fiscal goals. While the government aims to reduce crude-oil import costs and increase farmer incomes, critics argue the policy lacks a scientific basis and creates technical risks for existing vehicles [3, 4].

Nationwide protests reached a peak on June 10, 2026 [3]. Entrepreneur and TV personality Tehseen Poonawalla has led the movement, challenging the central government's assertion that the policy would lower fuel prices for the public [4].

The current mandate targets an ethanol blend in petrol of over 20%, known as E20 [3]. However, reports indicate the government is planning a further increase to a 25% blend, or E25 [1].

Opponents of the policy said that the transition has not resulted in any fuel-price relief for drivers [4]. They further cite concerns regarding vehicle compatibility, as higher ethanol concentrations can corrode engine components not designed for such blends [3, 4].

Poonawalla described recent developments as a "first victory" [4]. Despite this, he said "the battle is far from over" [4].

The central government said that the strategy is essential for national energy security. By substituting imported oil with domestically produced ethanol, the state intends to lower the overall fuel import bill [3].

"first victory"

The tension between India's environmental and fiscal goals and the practicalities of its automotive fleet highlights a significant policy gap. If the government pushes E25 without ensuring widespread vehicle compatibility or delivering direct price cuts to consumers, it risks intensifying public backlash and causing widespread mechanical failures in older vehicle models.
