The Government That Said E20 Was Safe, Then Said It Needed More Study

At 2:30 in the morning on July 30, Nitin Gadkari rose in Parliament to defend India's E20 ethanol blending program. The studies were in, he said, and they were clear.

These studies confirmed that even legacy vehicles did not exhibit any significant variations in performance, nor do they show abnormal wear-and-tear when operated with E20 fuel. — Nitin Gadkari

Then, in the same statement, he added that vehicles built between 2005 and 2016 might need their gaskets and rubber parts replaced, and that fuel efficiency in older vehicles could drop by 2 to 6 percent. ^[1] Hours later, at 10:15, Suresh Gopi, the Minister of State for Petroleum, told the same Parliament that the government would not raise the ethanol blend beyond 20 percent. The reason was straightforward.

Had automobile manufacturers not been fully satisfied with the results, they would neither have validated E20 fuel for older vehicles nor honoured warranty obligations. — Suressh Gopi

Proven in the morning, unproven by the afternoon. The contradiction was not a slip between two ministers who had not compared notes. It was the government's ethanol policy in miniature — a position that insists the science is settled while its own actions treat it as anything but. The arc that delivered the government to this point is barely a hundred days long. On April 21, Gadkari himself had called for India to push further still. ^[2]

In the near future, India should aspire to achieve 100 per cent ethanol blending. — Nitin Gadkari

On June 3, Petroleum Minister Hardeep Singh Puri stood beside the country's first mass-market flex-fuel vehicles — a Hero motorcycle and a Maruti Suzuki WagonR, both engineered to run on blends up to E85 or E100 — and declared the trajectory irreversible. ^[3]

India’s ethanol journey is unstoppable. — Hardeep Singh Puri

The government was not merely defending E20. It was building the architecture for E25, E85, E100. In June, it waived excise duties on blends up to E30, legally authorized pure ethanol as a vehicular fuel, and announced plans for 5,000 E100 dispensing stations by 2027. ^[4][5] The ethanol production capacity had been built to match: nearly 2,000 crore litres, almost double what E20 alone could absorb. ^[6] Then the backlash arrived. Delhi motorists protested reduced fuel efficiency and engine trouble. The Odisha Petroleum Dealers Association reported jammed carburettors even in BS-6 models — the newest generation — and urged a rollback to E10. ^[7] An estimated 75 percent of vehicles on Indian roads are not E20-compliant. ^[7] On July 23, the government announced it had not decided to raise blending beyond 20 percent, effectively capping the program. ^[8] On July 30, it made the cap explicit: no E25. The Supreme Court episode, a month earlier, had already revealed the gap between what the government says in public and what it concedes in a courtroom. On June 30, the Attorney General reportedly told the Court something striking.

The government is trying to experiment with 20% ethanol blending. We will have results of that by next year. — Government of India

The government rushed to deny the report.

These reports are completely false and do not reflect anything even close to the actual submissions made before the Hon'ble Court. — R. Venkataramani

But the Attorney General's reported framing — an experiment, results pending — is precisely what the government's own actions have been saying for weeks. The Automotive Research Association of India has only just begun testing E25 on compliant vehicles, with a final report not expected until late 2027. ^[9] The scientific basis for any decision beyond E20 does not exist yet. The government's lawyer said in a courtroom what its policy machinery has been signaling: E20 is still under observation. What turned a technical calibration into a political lockdown was the opposition's entry into the debate. On July 7, Arvind Kejriwal alleged the government had pressured automakers to falsely assure consumers that E20 was safe in pre-2023 vehicles, and demanded written compensation guarantees for any driver whose mileage dropped more than 10 percent or whose engine sustained damage. ^[10]

the government got Maruti Suzuki, Toyota Kirloskar, and Hero MotoCorp to falsely assure consumers that using E20 in E10 vehicles will cause no damage despite their owner manuals warning against using fuel with more than 10% ethanol — Arvind Kejriwal

The demand changed the stakes. Any government concession that E20 caused real-world problems would now vindicate Kejriwal's charge and potentially open the door to compensation claims. The political cost of admitting a problem had just exceeded the technical cost of denying one. The government's defense hardened in lockstep. Gadkari called the damage reports "paid campaigns and false narratives" and challenged critics to name a single vehicle damaged by E20. ^[10] Gopi, on July 27, told Parliament the complaints did not exist.

The Government has not received any widespread or substantiated complaints from vehicle manufacturers, automobile associations or consumer organisations regarding drastic reduction in mileage, slow pick-up and rusting of petrol tanks, attributable to E20 fuel. — Suressh Gopi

Two days later, his own ministry disclosed it had sold 6.35 million tonnes of rice to ethanol distilleries at 40 percent below cost — continuing to subsidize the very fuel whose problems it was denying. ^[11] The harder the government defends, the more it concedes. Gadkari's admission about gasket replacements and 2-to-6-percent efficiency losses contradicts Gopi's claim, made hours later the same day, that studies had found no meaningful effect on performance, durability, or material compatibility. ^[12] Gasket and rubber replacement is a material compatibility impact — by the government's own description. And a 2-to-6-percent mileage drop, confirmed by the government's own data, is precisely the kind of substantiated complaint Gopi insisted did not exist. The government cannot retreat without vindicating its critics. It cannot advance without studies it does not yet have. And it cannot defend its position without conceding the very problems — gasket wear, efficiency loss — that its political opponents are using to attack it. The political cost of admitting E20 has problems now exceeds the technical cost of denying them, so the denial continues. But every denial requires a concession, and every concession makes the next denial harder.
