NEW DELHI: The Ministry of Petroleum and Natural Gas has issued a detailed defence of India’s Ethanol Blended Petrol Programme, saying E20 fuel is safe for older vehicles, has undergone extensive testing and was introduced after more than two decades of policy development rather than through an overnight decision.
In a fresh set of frequently asked questions, the ministry also acknowledged that some vehicles may experience a 3% to 5% reduction in fuel economy when using petrol blended with 20% ethanol. It argued, however, that the mileage impact must be weighed against higher octane levels, lower emissions, reduced dependence on imported crude oil and increased income for farmers.
The clarification follows an earlier ministry statement issued on June 23, 2026, and explanations provided by automobile manufacturers at a press conference on July 4. The government said concerns about engine damage, consumer choice and the pace of India’s transition to E20 had persisted despite those interventions.
Ministry says E20 was not introduced in haste
Rejecting comparisons suggesting that India had rushed its ethanol targets while Brazil took decades to build its programme, the ministry said India’s ethanol journey began with a pilot project in 2001.
The programme was formally announced in 2004, while E5 petrol—containing 5% ethanol—was introduced in several states by 2006. A policy framework was notified in the Gazette of India in January 2013 during the United Progressive Alliance government.
Despite these early steps, ethanol blending remained at about 1.5% until 2014, largely because India lacked sufficient production capacity. At the time, the country depended heavily on sugarcane and had an annual ethanol production capacity of approximately 400 crore litres.
The government subsequently expanded the programme through the National Policy on Biofuels, introduced in May 2018. The policy widened the range of feedstocks, encouraged new production capacity and involved coordination among the petroleum, food, road transport, heavy industries and railway ministries.
In June 2021, NITI Aayog published the “Roadmap for Ethanol Blending in India 2020–25” following consultations with automobile manufacturers, oil companies, agricultural experts and other stakeholders.
The same year, Indian Oil Corporation, Bharat Petroleum Corporation and Hindustan Petroleum Corporation invited proposals for Dedicated Ethanol Plants in ethanol-deficit regions. These projects were supported by long-term purchase agreements and financing arrangements involving public-sector banks.
According to the ministry, India needed roughly 500 crore to 600 crore litres of ethanol annually to achieve 10% blending. As production capacity expanded towards 1,200 crore litres, the government concluded that a 20% target was achievable.
India reached 10% ethanol blending in June 2022, five months ahead of schedule. The country achieved the 20% target in 2025, five years before the original 2030 deadline under the National Policy on Biofuels, 2018.
From April 2026, all petrol sold across India was mandated to contain 20% ethanol and meet a minimum Research Octane Number of 95. Bharat Stage-VI vehicles were also required to comply fully with E20 emission standards.
The ministry said India shortened the implementation period by using technologies and lessons already tested internationally, rather than by compromising safety or scientific evaluation.
Why motorists cannot routinely choose pure petrol
The government also addressed demands that petrol pumps offer pure petrol, E10 and E20 simultaneously, allowing owners—particularly those with older vehicles—to select their preferred blend.
It rejected the proposal on logistical and economic grounds.
India has more than one lakh fuel retail outlets supported by refineries, depots, terminals, pipelines and transportation networks. Maintaining three separate base-fuel streams nationwide would increase storage and handling requirements, complicate inventories and raise distribution costs, the ministry said.
Premium petrol was not a suitable comparison, it added, because premium fuels are niche products made by mixing specialised additives into petrol and are sold in relatively limited quantities. Operating parallel nationwide supply chains for pure petrol, E10 and E20 would be a much larger exercise. Fuel stations, it appears, are not being encouraged to acquire restaurant-style menus.
The ministry also pointed to investments made in ethanol plants, distilleries, storage facilities and transportation infrastructure. It said public-sector banks had financed nearly ₹1 lakh crore a year in ethanol production and associated infrastructure over recent years.
Reverting to lower blending levels, it argued, could leave excess production capacity and affect investments made by farmers, cooperatives, businesses, financial institutions and public-sector companies.
Older vehicles and E10 compatibility labels
One of the most prominent concerns involves older vehicles whose manuals describe them as compatible with petrol containing up to 10% ethanol.
The ministry said such labels reflect the fuel standard in effect when a vehicle was homologated and certified. It argued that an E10 label does not automatically mean a vehicle becomes unsafe when national fuel specifications are subsequently upgraded following testing and regulatory approval.
Before E20 was introduced, evaluations were conducted covering engine durability, fuel systems, corrosion resistance, material compatibility, drivability, emissions, performance and fuel efficiency, according to the clarification.
The consultations involved automobile manufacturers, component suppliers, the Automotive Research Association of India, the Society of Indian Automobile Manufacturers, oil companies, testing agencies and technical institutions.
The government said manufacturers would not have certified E20 vehicles or continued honouring warranties had they not been satisfied with the testing and transition process.
As evidence from actual vehicle use, the ministry said Maruti Suzuki serviced 2.84 crore vehicles during the 2025–26 financial year, including 1.5 crore older vehicles that were not originally certified for E20.
According to the statement, the manufacturer reported no E20-linked corrosion, abnormal wear or reduction in component life. Hero MotoCorp was said to have reported a similar field experience.
The ministry maintained that India had not seen the volume of warranty claims, fuel-system failures or engine complaints that would be expected if E20 were causing widespread damage.
Mileage may decline in some vehicles
While dismissing claims of widespread mechanical damage, the government acknowledged that fuel economy may decline by between 3% and 5% in some vehicles.
Ethanol contains less energy per unit of volume than petrol, but the ministry emphasised other claimed benefits of E20, including a higher octane rating, better resistance to engine knocking, faster combustion, improved acceleration and cleaner engine operation.
It said the fuel produces negligible particulate emissions and can reduce lifecycle carbon emissions by approximately 40%.
The ministry therefore presented the mileage reduction as one part of a broader calculation involving emissions, energy security and agricultural income.
Why E20 petrol is not necessarily cheaper
The government also addressed the expectation that petrol should become cheaper because ethanol replaces a portion of conventional petrol.
It said maize-based ethanol is currently procured at approximately ₹71.86 per litre, excluding GST, transportation, storage and depot-handling expenses.
When international crude oil trades at around $70 a barrel, the ministry said, E20 can be more expensive to produce than pure petrol. If crude rises to between $120 and $130 a barrel, ethanol becomes comparatively cheaper.
The principal benefit, according to the government, is therefore not necessarily an immediate reduction in the price displayed at the petrol pump. Instead, ethanol reduces exposure to unpredictable international oil prices.
Nearly one-fifth of every litre of petrol sold in India now comes from domestically produced ethanol, whose procurement price is not directly affected by daily changes in Brent crude, geopolitical conflicts or shipping disruptions.
The ministry argued that this domestic component helps moderate the effect of global crude-price volatility on Indian consumers.
Government cites forex, emissions and farmer benefits
Since the 2014–15 Ethanol Supply Year, the programme has saved more than ₹1.97 lakh crore in foreign exchange, according to the government.
The ministry said ethanol blending had also substituted nearly 316 lakh metric tonnes of crude oil, reduced carbon dioxide emissions by approximately 952 lakh metric tonnes and transferred more than ₹1.66 lakh crore to Indian farmers.
“Our farmers are no longer merely Annadatas; they have become Urjadaatas, contributing directly to India’s energy security,” the ministry said.
India’s ethanol production capacity has risen to nearly 20 billion litres, compared with an estimated annual requirement of about 11 billion litres for sustaining E20, according to the programme’s 2026 milestones.
The government is also promoting E85 flex-fuel vehicles and examining higher ethanol blends. Flex-fuel versions of the Hero Splendor+ and HF Deluxe motorcycles were introduced in New Delhi as part of this transition.
Warning against adulteration
The ministry said ethanol and blended petrol must comply with Bureau of Indian Standards specifications and are subject to quality checks from distilleries to storage depots and retail outlets.
State Chief Secretaries have been asked to ensure strict enforcement against adulteration or procedural violations in the fuel supply chain.
While the government has presented industry servicing data and testing records to reassure motorists, the debate is unlikely to disappear solely through another round of FAQs. For consumers, especially those driving older vehicles, confidence will ultimately depend on consistent fuel quality, transparent warranty practices and continued publication of real-world performance data.
India’s E20 transition is no longer merely an environmental programme. It now sits at the intersection of transport policy, agricultural income, fuel affordability and national energy security—meaning that what enters a vehicle’s fuel tank has consequences extending well beyond its mileage display.
