Since April 1, 2026, every petrol pump in the country quietly stopped giving you a choice. It’s E20 now, twenty percent ethanol mixed into your petrol, whether your bike is a 2024 model or a faithful old scooter that has been part of the family longer than some cousins. Nobody voted on this. Nobody got a WhatsApp forward explaining it in advance either, which for India is genuinely unusual.
The government’s version of events is simple. Ethanol blending was supposed to hit twenty percent by 2030, and instead it arrived five years early, which the Petroleum Minister announced with the pride of someone who finished a marathon nobody else agreed to run. Less oil imported, cleaner emissions, better prices for sugarcane and grain farmers. On paper it sounds lovely, the kind of thing you’d nod along to in a PowerPoint.
Then you actually drive the vehicle.
A survey by LocalCircles in June found that 66 percent of people with pre 2023 petrol vehicles reported their mileage dropping by more than ten percent, up sharply from 45 percent just a month earlier. Over 44,000 people across 305 districts responded, and more than half also said they were visiting the mechanic more often than before. Mechanics themselves have been saying the same thing for months, quietly, the way mechanics say most true things, while charging you for a new gasket.
Automakers, through their industry body SIAM, have a slightly gentler number. They say mileage drops by two to four percent, not the double digit figures owners are reporting, and insist the fuel is safe even if older engines feel it a bit. Which is the automotive equivalent of “it’s not you, it’s your car,” except somehow it’s still your problem to solve.
Somewhere in the middle of all this a claim started going around that E20 cuts mileage by thirty percent, and the government stepped in firmly to correct the record. Thirty percent, it clarified, is actually just ethanol’s lower calorific value compared to plain petrol, not an actual real world mileage drop. Which is a bit like a restaurant insisting the smaller portion isn’t smaller, it’s just measured differently. Technically true, spiritually exhausting.
Then came the Supreme Court moment. In June, the government’s own Attorney General reportedly told the Court that the administration was, in his words, “experimenting” with the twenty percent blend, a phrase that landed with all the reassurance of a pilot casually mentioning mid flight that they’re still getting the hang of the plane. The ministry later clarified that the case was actually about ethanol procurement contracts, not the fuel’s merits, and called the experiment framing incorrect. Everyone nodded, filed it away, and moved on, the way we’ve all learned to do.
Politicians, naturally, could not resist. Delhi’s Chief Minister showed up personally at a petrol pump and a repair shop this month to talk to motorists and mechanics about lower mileage and mechanical trouble, then asked the Prime Minister to look into it. Which is a very efficient way to turn a fuel additive into a press conference, and honestly, fair play, the opportunity was sitting right there at the pump.
Meanwhile the official myth busting has taken on a life of its own. Concerned that ethanol’s sugar content might attract ants and bees to fuel caps, the government clarified that fuel grade ethanol is fully distilled, the sugars are gone, and the fuel actually contains insect repellent denaturants. There is also an official position now on whether ethanol’s water absorbing nature might quietly ruin your fuel tank, the short version being don’t worry, modern vehicles are built to keep water out anyway, ethanol or otherwise. It is genuinely remarkable that a government press note now doubles as pest control advice.
For vehicles that have crossed 20,000 kilometres, the official guidance is that rubber gaskets may need replacing, described helpfully as a “low cost fix,” which is technically accurate and also exactly what you’d expect someone to call a cost that isn’t theirs.
And here’s the part that never quite makes it into the ministry backgrounders. Ethanol procurement itself has gotten pricier than refined petrol, the government has admitted as much, yet the mandate rolls on regardless because of the bigger picture, energy security, farm incomes, the environment. All real, all fair points, and also all somewhat cold comfort to someone whose scooter now needs a service every third week instead of every third month.
There’s a public interest case sitting with the Supreme Court on all of this, which means eventually a bench of judges will get to decide whether a fuel additive constitutes a legal grievance, which feels like the natural endpoint for absolutely everything in this country these days.
For now the choice, such as it is, remains theoretical. You can complain to your mechanic, tag a minister on social media, or read a government FAQ explaining why the bees aren’t a real threat. What you cannot do, at any pump, anywhere, is simply ask for the petrol your vehicle was actually built for. That option quietly left the building back in April, and nobody’s inviting it back.
