The Centre has officially notified higher ethanol-blended petrol variants, including E22, E25, E27 and E30, marking the next phase of India’s push towards cleaner and more energy-secure fuels.
The Bureau of Indian Standards (BIS), which is responsible for framing regulatory standards for the ethanol blending programme, said it has established a new standard — IS 19850:2026 — for “E22, E25, E27 and E30 Fuel, Admixture of Anhydrous Ethanol and Motor Gasoline for Usage in Positive Ignition Engine Powered Vehicles.”
The move comes after India’s successful rollout of the E20 blending programme and signals the government’s intention to further increase ethanol content in petrol in the coming years. Officials have said higher ethanol blending can help reduce dependence on imported crude oil, lower emissions and support domestic sugarcane and agricultural sectors.
The notification also comes at a time when fuel prices are rising across the country, with Brent crude prices remaining above USD 100 per barrel amid supply concerns linked to the ongoing West Asia conflict. The government has been increasingly focusing on ethanol blending as part of its long-term strategy to reduce exposure to global crude oil volatility.
However, the government has not specified a timeline yet for the commercial rollout of E22-E30 fuels at retail outlets.
India’s ethanol blending programme has witnessed rapid expansion over the past decade. In 2014, ethanol blending in petrol stood at just 1.53%. By 2022, the country achieved 10% blending — five months ahead of schedule — before successfully reaching the 20% ethanol blending (E20) target in 2025.
The ethanol blending programme is a major step towards reducing India’s dependence on imported crude oil. India currently imports nearly 85% of its crude oil requirement, making the economy highly vulnerable to global price fluctuations and geopolitical disruptions.
What It Means For Your Vehicles
Despite growing consumer concerns over the impact of E20 fuel on vehicle engines, Union Petroleum and Natural Gas Minister Hardeep Singh Puri has maintained that there has not been a single officially reported case of engine failure or breakdown since 20% ethanol-blended petrol became the base fuel across India.
Drawing comparisons with global practices, Puri has repeatedly cited Brazil’s long-running ethanol programme, noting that the South American country has successfully operated vehicles on E27 fuel for years without major operational issues.
The government’s reassurance comes amid complaints from some motorists who claim that the shift to higher ethanol blends has led to reduced mileage, performance lag and premature engine wear in older vehicles. Officials, however, have dismissed these concerns, saying they are not backed by verified statistical data. According to the government, E20 fuel offers better acceleration, smoother ride quality and nearly 30% lower carbon emissions compared to the earlier E10 blend.
Automobile manufacturers have already started producing newer vehicles that are factory-compatible with ethanol blends up to E20. However, experts have pointed out that older vehicles may face compatibility issues due to ethanol’s higher corrosive properties and different combustion characteristics.
To address such concerns, the ministry has said vehicle owners who believe their older vehicles require tuning or component replacement can approach authorised manufacturer service centres, which have been equipped to handle modifications linked to higher ethanol usage.
The recent notification of higher ethanol-blended petrol variants — including E22, E25, E27 and E30 — does not mean these fuels will immediately become available at retail fuel stations. Their rollout is expected to happen gradually over time.
While countries such as Brazil provide successful examples of higher ethanol adoption, the long-term impact of fuel blends above E20 on India’s large base of older vehicles will likely be closely watched in the coming years.
