E20 Petrol Crisis: Why India's Opposition Won't Unite Against It

The entire ethanol issue could have been one of the greatest breaking points for the opposition in years, allowing it to target this government directly. A policy rushed five years ahead of schedule, a fuel mandate with no opt-out, millions of angry vehicle owners, a court ruling against a car manufacturer and even the government's own admission in Parliament that it never measured what it was mandating. And yet the opposition, as a bloc, has done almost nothing with it. That gap, between how big this issue should be politically and how small the opposition has chosen to make it, is the question that matters most here, and it is the one this piece sets out to answer with facts rather than assumptions.

The scale of the anger, in numbers

Start with what is actually documented, because the scale of public frustration here is not in dispute, even where its political response is. Arvind Kejriwal's online petition demanding E20 be made optional rather than mandatory crossed two lakh signatures, and on August 1 he held a "National Town Hall Against E20" at Delhi's Constitution Club that reportedly drew participation, online and offline combined, of more than seven lakh people. He used the platform to lay out three demands: pure petrol and E20 both available at every pump, E20 priced cheaper than pure petrol, and petrol brought below ₹84 a litre. Three days later, on August 4, Kejriwal and roughly 100 AAP supporters, including Manish Sisodia, Rajya Sabha MP Sanjay Singh, and Jasmine Shah, tried to march to the Prime Minister's residence, carrying more than 2.3 lakh petitions. Delhi Police stopped them at Firoz Shah Road and, after a stand-off, took custody of the petitions once the organisers were told the Prime Minister would not meet them. The BJP dismissed the entire effort as political theatre, with Delhi BJP president Harsh Malhotra accusing Kejriwal of copying an earlier opposition protest near the same residence.

That same day, the Delhi Taxi and Tourist Transporters and Tour Operators Association, backed by the All India Motor Transport Congress and the All India Motor and Goods Transport Association, had planned its own march to Parliament to demand an independent scientific review of the ethanol-blending policy. Delhi Police denied that permission, too. The transporters redirected to Rajghat instead, laid flowers at Mahatma Gandhi's memorial, and held their demonstration there, with association president Sanjay Samrat telling reporters that the group had chosen "the path of truth and non-violence" after the march itself was blocked. A grassroots online movement calling itself the "E-20 Janata Party" had already built a substantial following on Instagram and X in the days before, entirely outside any political party's involvement, and the transporters were careful, both before and after August 4, to say they had no association with it or with any political outfit.

Two days before all of this, on Saturday, Poonawalla alleged he was placed under house arrest at his Greater Kailash home, without any written order, hours before a planned solo walk to Gandhi Smriti and a day-long hunger strike, with Delhi Police reportedly citing fears that thousands of protesters would show up. Taken together, the past week has produced a genuinely large, genuinely public reckoning with this policy, a town hall in the hundreds of thousands, a blocked march to the Prime Minister's house, a blocked march to Parliament, and a commentator confined to his own home. What it has not produced is a single opposition party, transport union, or grassroots movement standing on the same stage at the same time.

Set against all of that, the government's own numbers in Parliament this week landed with real weight. Officials admitted they have never assessed how many vehicles in India are actually E20-compatible, an extraordinary gap for a mandate that removed every other option from nearly 90,000 fuel stations nationwide. Nitin Gadkari himself told the Lok Sabha that mileage loss runs between two and six per cent, a wider band than the government had previously cited. It offered manufacturer service data alongside this: one automaker reported servicing 28.4 million vehicles in FY 2025-26, of which around 15 million were never certified E20-compatible, with no cases of corrosion or abnormal wear attributed to the fuel. Owners describe something else entirely. Saurav Joshi, India's most-subscribed individual YouTuber, said his Mercedes dropped from 16 or 17 kilometres per litre to 5. A Chandigarh-based owner separately flagged a ₹4-crore G-Wagon developing problems soon after switching to the blend. A Raipur consumer court ruled on July 14 that Maruti Suzuki must replace a doctor's Grand Vitara after repeated stalling, in a case where the company's own "adulteration" defence collapsed once the court found the vehicle had simply been filled with E20 instead of the E10 it was built for. Maruti is contesting the order.

Tehseen Poonawalla, in conversation with French Press Global, put the accountability question in the plainest terms he could. "If the fuel is adulterated, who fills the fuel? Who sends that fuel?" he said. "Obviously, the government sends the fuel. So the government needs to be blamed for it." On the Raipur case specifically, he said the ruling exposed exactly the problem owners have been describing for months. "If in E10-compliant vehicles E20 fuel is going, then who's responsible for it?"

He was equally direct about what the crowd at Jantar Mantar was actually asking for. "The police thought that people would not come up. They restricted us to only two hundred people," he said. "However, more than five thousand people turned up at Jantar Mantar to protest, and these were ordinary people who owned vehicles. 99% of them had their vehicles on loan, and I was overwhelmed. These were the citizens of India who were honest, who paid their taxes." He tied that anger to a simple, almost domestic grievance. "When we purchase a vehicle, we pay taxes for fifteen years in advance," he said. "It should be a matter of joy and convenience for us to own a vehicle, not a matter of inconvenience for us to own a vehicle." He said the protesters kept returning to the same two questions. "Why not E20 fuel be made available for vehicles that are prior to 2023 and E10 compliant? They also said if E10-compliant vehicles could not take E20 fuel, why were the vehicles later upgraded?" And on why mileage has become the flashpoint it has, he was equally blunt: "Please understand, an average or mileage is the most important thing for an Indian when they buy a vehicle."

His demand, still unmet, is for every car manufacturer to publish a full account of how many vehicles have come in for service in the past year due to fuel-related damage, whatever the official explanation given. "We are now demanding all car companies make a list of all the vehicles that are spoiled due to fuel adulteration, which could be E20, and give us a list," he said. "In the last year, how many cars have come and have been serviced due to fuel adulteration, fuel pump, fuel injectors, or engines being spoiled?"

An opposition that keeps finding one name and stopping there

Given all of this, the natural question is why the opposition has not built a single, sustained campaign around it. Individually, several leaders have spoken, and Kejriwal has now gone further than most, from a personal video tour of Delhi mechanics calling the country "an experimental lab for the Modi government," to a seven-lakh-strong town hall, to a blocked march on the Prime Minister's residence itself. AAP MP Sanjay Singh has taken the attack further still, alleging in Parliament that the policy would ultimately benefit foreign ethanol producers over Indian farmers, and pointing to a sharp rise in ethanol imports from the United States. Congress's Priyank Kharge called Indian motorists "guinea pigs." Karnataka Congress president BK Hariprasad posted about vehicles breaking down "across the country." NCP (Sharad Pawar faction) MLA Rohit Pawar raised concerns specifically about older vehicles. But even with AAP's escalation, none of these threads has merged into a shared platform, a joint press conference, or a common set of demands that the opposition, as a bloc, is willing to put its full weight behind. Congress and NCP were notably absent from Kejriwal's town hall and his march to the Prime Minister's residence, just as AAP was absent from Congress's campaign against Gadkari's family business.

Congress's national leadership has instead settled on one specific, recurring line of attack: the ethanol business run by the sons of Union Road Transport Minister Nitin Gadkari. It is worth being precise about what that business actually looks like, because the numbers are genuinely startling. Nikhil Gadkari's CIAN Agro Industries reported quarterly revenue of roughly ₹17 crore in the first quarter of FY24, before the company pivoted hard into ethanol production. By the first quarter of FY26, that figure had reportedly climbed to around ₹510-511 crore, with profit rising by a factor in the tens of thousands of per cent over the same window, and full-year FY25 revenue reported at over ₹1,000 crore, up from roughly ₹171 crore the year before. The company's stock, trading around ₹40 in August 2024, went on to hit successive upper-circuit limits, reaching a market capitalisation of ₹9,000 crore at its peak. CIAN also absorbed Manas Agro Industries, run by Gadkari's other son, Sarang, as a subsidiary along the way. None of this is alleged or disputed; it is drawn from the company's own disclosed financials.

There is also a structural oddity here that deserves more attention than it has received. Nitin Gadkari is not India's Petroleum Minister. That portfolio belongs to Hardeep Singh Puri, with Suresh Gopi as Minister of State. And yet Gadkari has, for years, been the government's single most visible and vocal evangelist for ethanol blending, publicly championing it at rallies and industry events well before it became mandatory policy, and defending the mileage figures in the Lok Sabha himself this week, in a portfolio that is not formally his to speak for. Whether that pattern is a coincidence or something closer to a family business finding a very convenient political tailwind is precisely the kind of question a serious, sustained opposition campaign would be built to answer. Congress has raised it. What Congress has not done is take that same question and turn it on itself.

The mills nobody in the opposition wants to talk about

Because the uncomfortable truth is that Gadkari's family is far from alone in this picture. Maharashtra's sugar cooperative sector, which supplies a meaningful share of India's ethanol, is not a BJP-only institution. It is a patronage network that runs through every major party in the state, and reporting on its ownership has consistently identified NCP- and Congress-linked leaders as among its largest stakeholders, with the Sharad Pawar family's own cooperative network cited as one of the most extensive in the sector. Rohit Pawar, who has publicly raised concerns about E20's effect on older vehicles, sits inside a party whose own network of sugar interests would be directly implicated by the kind of full ownership disclosure that a genuine anti-ethanol campaign would eventually have to demand. Congress's state units in Maharashtra carry the same exposure.

Some numbers put a finer point on it. Swabhimani Shetkari Sanghtan, a sugarcane farmers' union that has tracked the state's defaulting sugar mills, has counted roughly 180 such mills across Maharashtra, of which 77 are linked to BJP leaders, 53 to NCP leaders, and 43 to Congress leaders, with the remainder tied to Shiv Sena, and cane price arrears across these mills reported at close to ₹5,000 crore.* Read plainly, that is not a story of one party's ethanol windfall. It is a story of every major party, including the ones currently criticising the government, holding a direct financial stake in the same cooperative economy that ethanol policy has made more valuable.

*This figure reflects one farmers' union's count of defaulting mills specifically, not a comprehensive census of all sugar mill ownership in Maharashtra.

This is the asymmetry that explains the silence better than anything else does. Attacking Gadkari's sons is free. It costs Congress nothing, implicates only the ruling party, and lets the opposition look like it is holding power to account without ever turning the microscope on itself. Attacking the cooperative sugar economy as a whole would not be free. It would require opposition leaders to ask for disclosure from their own state units, their own allies, their own financial backers, and that is a bill nobody in the opposition has so far been willing to pick up. The result is a campaign that talks about one family's stock price while staying almost entirely silent on an entire industry that has quietly enriched leaders on every side of the aisle.

What comes next?

This past week answered one question and left the bigger one hanging. It proved, decisively, that the public appetite for this fight is real: seven lakh people engaging with a single town hall, over 2.3 lakh petitions carried to the Prime Minister's doorstep, transporters willing to march on Parliament and, when blocked, on Gandhi's memorial instead. What it has not produced, even now, is a moment where AAP, Congress, NCP, and the transporters stood on one stage with one set of demands. Every ingredient for that unified campaign is already sitting on the table: a documented government admission of no compatibility data, a court ruling, a Supreme Court hearing that conceded most vehicles were never built for this fuel, a commentator confined to his own home for planning a silent protest, and now two blocked marches in a single day. What has been missing for over a year is an opposition willing to take it all on at once, rather than the piece that costs each of them nothing to say out loud.
