India Adopts Stricter Fuel Standards as Crude Oil Crisis Intensifies

India Establishes Regulatory Framework for Higher Ethanol Blends

The Bureau of Indian Standards (BIS) has formally notified fuel specifications for higher ethanol-blended petrol variants, including E22, E25, E27, and E30. This move creates a regulatory framework for the next phase of India's ethanol blending programme.

In a notification dated May 15, 2026, the BIS established the 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 standards define specifications for higher ethanol-petrol blends intended for use in petrol-powered vehicles.

India's ethanol blending programme has been accelerated in recent years, with the government advancing the target for 20 percent ethanol blending in petrol from 2030 to the ethanol supply year 2025-26. According to data released by the Ministry of Petroleum and Natural Gas earlier this year, India had already crossed the 18 percent ethanol blending mark nationally.

The government had launched E20 fuel at select retail outlets in 2023 as part of a phased introduction. Automobile manufacturers subsequently began introducing E20-compatible vehicles across segments in line with government timelines and fuel transition plans.

The latest BIS standards indicate that regulators are preparing the framework for fuels with ethanol content higher than 20 percent, even as the wider E20 transition remains underway across the country. Government officials have discussed the possibility of moving towards even higher ethanol blends such as E85, with a focus on examining the readiness of fuel distribution systems, vehicle compatibility, and supply chains.

India's ethanol blending programme has become a central part of the country's energy diversification strategy, aimed at reducing dependence on imported crude oil and increasing the use of domestically produced biofuels. The government imports more than 85 percent of its crude oil requirement, making fuel diversification and import substitution a recurring policy focus.

The BIS notification does not specify a timeline for commercial rollout of E22-E30 fuels at retail outlets. Fuel availability and deployment decisions are expected to depend on subsequent policy directions from the petroleum ministry and oil marketing companies.
