The Central Government has announced new fuel standards for petrol blended with up to 30% ethanol as concerns grow over energy security due to the ongoing West Asia crisis and rising crude oil prices.
The Bureau of Indian Standards (BIS) on May 18, 2026, issued new technical norms for E22, E25, E27 and E30 fuel variants. These fuels contain 22%, 25%, 27% and 30% ethanol mixed with petrol respectively.The notification only sets technical standards for these higher ethanol blends and does not make E30 fuel compulsory for immediate sale across the country.
The move is aimed at reducing India’s dependence on imported crude oil amid fears of global supply disruptions. Concerns over the possible closure of the Strait of Hormuz, a key route for nearly 20% of the world’s oil supply, have further pushed the need for alternative fuel options.
Over the past few years, the government has actively promoted E20 fuel. However, some vehicle owners and experts have expressed concerns about reduced fuel efficiency and higher maintenance costs, especially in older vehicles using higher ethanol blends.Union Petroleum and Natural Gas Minister Hardeep Singh Puri had earlier stated that no cases of engine failure or breakdown linked to E20 fuel had been reported. He also pointed to Brazil as an example where E27 fuel has been used successfully for several years.Industry groups and biofuel manufacturers have welcomed the move, saying India has surplus ethanol production and needs to cut dependence on imported oil.
At the same time, experts have cautioned that introducing fuel blends beyond E20 will require proper coordination in vehicle compatibility, fuel supply systems, and distribution infrastructure across the country.
