Achieving E20 blending by 2025, five years ahead of the earlier 2030 deadline, is a 'great achievement,' and a government committee is now preparing the roadmap beyond E20, towards E27 or E30, Sanjeev Chopra, secretary in the Department of Food and Public Distribution, Ministry of Consumer Affairs, said on Monday at a SIAM event.
His remarks come amid heightened social media discussions about the impact of E20 fuel on the fuel efficiency and engines of cars.
Petroleum Minister Hardeep Singh Puri said last Friday that no engine failures had been reported since the E20 blend's rollout and that the performance

India's ethanol transition: A new blend, but a bumpy ride
Synopsis India's rapid shift to E20 fuel, containing 20% ethanol, is causing unforeseen issues for car owners. Many vehicles, designed for E10 fuel, experience reduced mileage and engine problems due to E20's corrosive properties. While the government touts economic and environmental benefits, consumers face unexpected maintenance costs and a lack of clear information about fuel compatibility. ANI The govt says that performance issues can be addressed via routine servicing and minor part upgrades. But for owners, it's about not being left in the dark. When Rahul Vaidya noticed his 2019 Volkswagen Vento's mileage drop from a steady 11-12 kmpl to just 7-8 kmpl, he initially blamed it on traffic. Or maybe it was the age of the car, he time, he figured that the response to a dab on the accelerator wasn't as crisp as it used to be. The ride felt heavier, and the fuel gauge continued to hover near E faster than ever. After months of living with these issues, he finally took his car to the service centre. The diagnosis was swift - his car wasn't E20-compliant. In case you have been living under a cave, the petrol now being sold across India contains 20% ethanol - a formulation Vaidya's Vento wasn't designed to handle. Unless reinforced, ethanol-sensitive components like rubber seals, fuel lines and gaskets degrade and the engine, uncalibrated for this new fuel mix, underperforms. The fix: replace critical parts and recalibrate the engine. "These changes restored the performance," Vaidya said. "But I had no idea my car wasn't ready for E20 in the first place."He's not Nair, who owns a 2021 Suzuki Brezza, saw his mileage drop by more than a fifth. Jerky drives, poor pick-up, and sluggish acceleration became the norm. After much back-and-forth with mechanics, he too learned the cause - and car, though newer, needed ECU tuning and E20-compatible components to handle the new fuel. Once fixed, the issues Vaidya and Nair's experience points to a larger ethanol transition is outpacing consumer awareness. And that is creating major issues for India's automobile owners, oil cos, automakers and lawmakers who are blaming each other. Simply put, one of the biggest transitions in fuel standards ever in India missed taking people along. As part of an ambitious ethanol-blending programme, the Indian government mandated E20 fuel availability across the country from nearly two and half years back. From April 2023, all new vehicles were required to be E20-compliant, with stricter enforcement from April nine out of 10 cars currently on Indian roads are only E10-ready, meaning they're built to handle a maximum of 10% ethanol in petrol. Mixing higher concentrations can affect their fuel efficiency, engine health and long-term with consumer experience playing out over a period of time, that is creating discontent among car owners. Many consumers don't even know what E20 is - or whether their vehicle can handle it. "There's a glaring gap in awareness," said Naveen Soni, former president of Lexus India. "OEMs must educate car buyers. Consumers are stakeholders too. They deserve transparency."Service centres report increasing cases of rough idling, knocking engines, worn gaskets, and fuel pump failures. The fixes are usually straightforward - replacing rubber hoses and recalibrating engines - and can often be done during regular servicing. But not all technicians know what to look for, and there's no escalation protocol in place the issues consumers are facing lagging the rolling out of the fuel by a few months at the very least, attribution of the problem to the fuel is creating simmering discontent the average driver, the shift to E20 feels subtle - until it isn' no standardised labeling at fuel pumps to indicate what blend is being dispensed. Car owners unknowingly fill up with E20, assuming it's the same petrol they've always used. But behind the scenes, the ethanol's corrosive and hygroscopic nature - it absorbs water from the air - wreaks havoc if the vehicle sits idle for fuel itself doesn't help. Ethanol has around 34% less energy content than petrol, meaning it naturally delivers fewer kilometers per executives estimate a 7% efficiency drop in non-E20 vehicles, though official studies, like those from ARAI and the Ministry of Petroleum and Natural Gas (MoPNG), claim it's only 1-6%.Reji Mathai, director, ARAI says in the run up to the implementation of E20, ARAI, Society of Indian Automobile Manufacturers (SIAM) and Indian Oil, under the directive of Ministry of Petroleum and Natural Gas (MoPNG) had undertaken a joint study where they picked up new and old E10 compatible vehicle mix of two and four wheelers (BS VI & BS IV) and evaluated them on E20."The vehicles performed satisfactorily and there was a minor increase of 2 to 6% in fuel consumption. The accelerated lab tests for material compatibility showed some degradation of certain plastics & elastomers that come in contact with the fuel. However, field trials showed no abnormalities."Car and two-wheeler manufacturers are walking a tightrope. Many unofficially admit that warranties may not hold if E10-designed cars use E20 companies, including market leader Hero MotoCorp, have issued advisories to customers on the potential impact of the E20 fuel ."Older vehicles, manufactured prior to April 2023, may require modifications in the engine-fuel system for it to be tuned to run efficiently on E20 fuel," it said on its website. "We didn't ask for ethanol blending," said a senior executive at a major carmaker, speaking anonymously. "So why should we foot the repair bill? Rubber and plastic parts corrode, especially when the car isn't driven regularly. It's a known issue."

According to MoPNG, from 2014 to 2025, ethanol blending has helped India save over ₹1.44 lakh crore in foreign exchange, substitute 245 lakh metric tonnes of crude oil, and reduce CO₂ emissions by 736 lakh metric tonnes - equivalent to planting 30 crore the economic alignment with agriculture and energy security - including benefits to sugarcane farmers and lower crude oil dependency - has left average consumers playing catch-up."Earlier, sugar prices were down and farmers struggled," said Deepak Ballani, Director General of the Indian Sugar & Bio Energy Manufacturers Association.

"The extent will vary by manufacturer and model, depending on how the engine is tuned, and actual mileage will still be influenced by driving style and road conditions." The ministry maintains that performance issues can be addressed via routine servicing and minor part upgrades.

By adding 40 mL of fuel system cleaner per full tank, riders can prevent gum formation and protect parts like gaskets and butterfly walls. This cleaner is easily available at fuel stations for around ₹80-100. It's about the right to know what's going into their tanks - and what it is doing to their vehicles.

Ethanol-blended petrol E20: Counting gains
India's transition to E20, petrol blended with 20% ethanol, is aimed at cutting emissions, enhancing energy security, saving foreign exchange, and boosting farmer income, according to government assurances. These statements come in response to public concerns that E20 use reduces fuel efficiency, accelerates wear and tear, and could result in rejection of insurance claims for non-compliant vehicles. Independence Day 2025 Before Trump, British used tariffs to kill Indian textile Bank of Azad Hind: When Netaji gave India its own currency Swadeshi 2.0: India is no longer just a market, it's a maker Ethanol Blending Milestones (OMCs) 1.53% – 2014 10% – June 2022 12.06% – ESY* 2022–23 14.60% – ESY 2023–24 19.93% – ESY 2024–25^ 27% Ethanol Norms by Aug: Nitin Gadkari *ESY: 1 Nov–31 Oct | ^July 2025 Concerns Fears raised about drastic mileage reduction and faster wear of some rubber and gasket parts in older vehicles when using E20. Ministry of Petroleum and Natural Gas (MoPNG) admits a marginal decrease (1–2%) in mileage in E10 vehicles and those calibrated for E20, and 3–6% for others. However, MoPNG says this can be minimised through improved engine tuning and use of E20-compatible materials. Post-April 2023 vehicles are E20-compliant, MoPNG quotes SIAM. (Inexpensive) replacement of some rubber parts/gaskets advised in certain older vehicles after 20–30K km run, says ministry. Argument raised that ethanol-blended fuel should be sold cheaper because of its lower calorific value; however, MoPNG says current weighted average ethanol procurement price (Rs 71.32/L as of July) is now higher than petrol. Fears of insurance cover not valid, says ministry. Benefits From ESY 2014–15 to ESY 2024–25 (July): Crude oil substitution: 245 lakh metric tonnes Foreign exchange saved: Rs 1,44,087 crore CO2 emission reduction: 736 lakh metric tonnes (equivalent to planting 30 crore trees) GHG emissions: Sugarcane and maize-based ethanol emit up to 65% and 50% less GHG than petrol, respectively. Lower carbon emissions: ~30% vs E10 fuel. Farmer income: E20 programme expected to pay farmers Rs 40,000 crore in 2025 alone. Higher octane ethanol: E20's RON is 108.5 vs petrol's 84.4. Better Acceleration RON (Research Octane Number) 95 with blending of E20, resulting in better anti-knocking properties and performance. Economic impact: Large forex savings, rural income improvements, elimination of sugarcane arrears, support for maize cultivation. The Brazil Template Brazil has had E27 ethanol blend in place for years, with no significant issues reported. By 2011, 83.1% of new cars sold in Brazil used flex-fuel technology, enabling engines to run on any mix of ethanol or petrol. Toyota, Honda, and Hyundai produce vehicles designed for ethanol blends. Brazilian regulators recently approved an increase in ethanol and biodiesel blending into fossil fuels, effective 1 August. Brazil's CNPE (National Energy Policy Council) to increase ethanol–petrol blending rates to 30% (E30). Brazil is the largest producer and user of ethanol from sugarcane, and the biggest ethanol exporter in the world. However, Brazil's ethanol production programme Proálcool (launched in 1975 and ended in 1990) faced problems. Risks include: Cheaper oil prices Rise in ethanol procurement prices Diversion of sugarcane to making sugar for exports
