The Indian government has not taken any decision to raise ethanol blending in petrol beyond the current 20 per cent (E20) level, Minister of State for Petroleum and Natural Gas Suresh Gopi told the Rajya Sabha on Monday, 20 July. Any future increase, the minister stated in a written reply, would be considered only after comprehensive scientific and technical studies and consultations with all relevant stakeholders.

Government's Position on E20 and Beyond

'Any proposal to increase the blending level would be considered only after comprehensive scientific and technical studies and consultations with automobile manufacturers, oil marketing companies and research institutions,' Gopi said in his written reply to the upper house.

The minister's statement comes amid ongoing public debate and media reports questioning the safety of high-ethanol blends for older vehicles not certified for E20 use. The government's position signals that no push to E25 or higher is imminent, and that the current programme will be consolidated before any further escalation.

India's Ethanol Blending Journey: A Milestone Achieved Early

India achieved its 20 per cent ethanol blending target five years ahead of its original schedule — a significant policy win. The average blending level climbed from approximately 1.53 per cent in 2013-14 to 20 per cent during the 2025-26 ethanol supply year, the result of more than two decades of phased implementation across the country's fuel distribution network.

Notably, this progression represents one of the fastest ethanol blending scale-ups among major emerging economies, driven by a combination of government mandates, procurement guarantees for farmers, and infrastructure investment by oil marketing companies.

Economic and Environmental Gains Since 2014-15

According to Gopi, the ethanol blending programme has delivered measurable economic and environmental benefits since 2014-15. These include:

Foreign exchange savings of more than ₹1.97 lakh crore, a reduction in crude oil imports of nearly 316 lakh tonnes, a cut of approximately 952 lakh tonnes in carbon dioxide emissions, and additional income of over ₹1.66 lakh crore generated for farmers who supply sugarcane and other feedstocks to the ethanol value chain.

Vehicle Safety Concerns: What the Data Shows

Addressing widespread concerns — amplified through media reports and social media — about engine failures, fuel pump damage, corrosion, and water contamination linked to E20 fuel, the minister said these issues have been scientifically examined and found to lack verified evidence of widespread impact.

He cited data showing that more than 20 crore two-wheelers and over 3 crore petrol cars — including many manufactured before E20 certification standards were introduced — have been running on E15-plus and E19-E20 fuel for between two-and-a-half to three-and-a-half years without confirmed widespread engine failure or vehicle breakdown.

Industry data cited by the minister further reinforced this position. One leading passenger vehicle manufacturer analysed service records of 2.84 crore vehicles during 2025-26, including around 1.5 crore vehicles not certified for E20, and found no damage attributable to the fuel. A leading two-wheeler manufacturer reported similar findings, according to Gopi.

What Comes Next

With E20 now embedded in India's fuel supply, the policy focus is expected to shift toward ensuring consistent blending quality and expanding feedstock diversity — including rice, maize, and agricultural waste — beyond the traditional sugarcane base. Any decision on higher blending targets will hinge on the outcomes of scientific consultations that have not yet been formally commissioned, according to the government's current position.
