The government cited logistical challenges and investments in ethanol infrastructure while acknowledging that E20 fuel delivers 3-5 per cent lower mileage than conventional petrol
Brazil avoided it, but India seems to be rushing through the ethanol transition at consumers' expense viewpoint
Petrol blended with 20 per cent ethanol (E20) can reduce fuel economy by 3-5 per cent in some vehicles, the Oil Ministry said on Friday, but argued the impact is outweighed by benefits, including a higher octane rating, superior anti-knock characteristics, faster combustion, better pickup, smoother acceleration, cleaner engine operation, and lower lifecycle carbon emissions. In a detailed question-and-answer document issued to counter criticism of the Ethanol Blended Petrol Programme, the Ministry of Petroleum and Natural Gas said E20 was a "cleaner, higher-quality and more efficient fuel" than E10 or pure petrol and had been rolled out only after years of scientific testing, consultations with automobile manufacturers and the expansion of domestic ethanol production. The ministry rejected concerns that the programme had been implemented too quickly, saying India's ethanol blending initiative dates back to pilot projects launched in 2001, with 5 per cent blending introduced in parts
If one-fifth of every litre of petrol is now ethanol, why hasn't E20 become cheaper? Here's the government's answer
India has already achieved 20% ethanol blending and is now looking beyond E20. But as debates over mileage, vehicle compatibility and consumer concerns continue, Brazil's decades-long biofuel journey
Petroleum minister says E20 has been used safely for nearly two years and argues higher ethanol blending will reduce crude imports, support farmers and strengthen India's energy security
India's E20 rollout should balance energy security with consumer choice, smoother vehicle transition and a shift towards more sustainable ethanol feedstocks
Aam Aadmi Party national convenor Arvind Kejriwal on Tuesday said he would write to three major automakers, seeking written assurances that the use of E20 fuel does not damage engines or reduce mileage. He also said that he would write to Prime Minister Narendra Modi regarding the "strong protest" by people against ethanol blending and would urge him that the fuel be made optional. Addressing a press conference, Kejriwal named Maruti Suzuki, Toyota Kirloskar and Hero MotoCorp, alleging that their public statements contradicted the guidance in the owner manuals of their vehicles. "I will write letters to all of them... I will tell them that your owner manual says one thing, but you are saying something else. Give in writing that if the mileage of your vehicle drops by more than 10 per cent, will you compensate the customer," Kejriwal said. "If using E20 ethanol in your vehicle damages the vehicle or causes wear and tear, will you compensate for the replacement of those components?,"
A LocalCircles survey says 66 per cent of pre-2023 petrol vehicle owners reported a mileage drop of more than 10 per cent, while 31 per cent want the option to return to E0 or E10 fuel
The government and automakers have been on the defensive after weeks of complaints on social media
Maruti Suzuki's Rahul Bharti said E20 fuel has 3-3.5 per cent lower calorific value than E10 petrol, adding that driving and maintenance factors cause wider mileage variation
Industry experts defended India's E20 rollout, saying the ethanol blending programme followed years of testing and consultations, with no major concerns found by automakers and research bodies
The government on Friday issued a detailed rebuttal to what it described as misinformation circulating on social media about the country's E20 ethanol blending programme, rejecting claims ranging from excessive water consumption and engine damage to insurance invalidation and environmental harm. In a 10-point clarification, the Ministry of Petroleum and Natural Gas said the programme, under which petrol contains up to 20 per cent ethanol, is supported by scientific studies, international experience and regulatory safeguards. Rejecting claims that producing one litre of ethanol consumes 10,000 litres of water, the ministry said only surplus rice, cleared after meeting national food security requirements, is diverted for ethanol production. It added that ethanol distilleries consume about 3-5 litres of processed water per litre of ethanol and increasingly operate Zero Liquid Discharge systems to recycle water. The ministry also said maize, which now accounts for more than 40 per cent
The Centre defended the mandatory use of 20 per cent ethanol-blended petrol after criticism over fuel efficiency and vehicle performance fuelled calls for protests
From E20 petrol and EVs to rooftop solar and rising electricity use, India's energy transition is reaching households. But are consumers ready for the costs and is government support enough?
BPCL's Rs 1,775 crore integrated 1G-2G bio-ethanol refinery in Bargarh will convert paddy straw into fuel, support farmers and strengthen India's clean energy transition
Ministry says reports misrepresented the Attorney General's submissions before the Supreme Court on ethanol allocation and stressed the national E20 programme was never described as an experiment
Compared with May 2026, the share of respondents reporting a mileage decline of more than 10 per cent increased by 21 percentage points within a month, representing a 47 per cent jump
