Key takeaways

The Ministry of Petroleum and Natural Gas rejected claims of over-blending, pointing out that nationwide tests on 893 samples showed ethanol levels strictly within the 19% to 21% limit.
Since ESY 2014-15, India's ethanol blending initiative has saved over Rs 1.97 lakh crore in foreign exchange and reduced CO2 emissions by 952 lakh metric tonnes.
Official test data from ARAI confirms that E20 fuel causes only a 1% to 2% efficiency drop in calibrated vehicles, refuting claims of a widespread 10% mileage drop.

The Ministry of Petroleum and Natural Gas and public sector Oil Marketing Companies (OMCs) rejected claims made by the Karnataka Government.
State tests alleged that retail petrol sold in Karnataka contained 26% to 31% ethanol, exceeding statutory limits.

Nationwide compliance tests on 893 samples across 27 States and UTs showed ethanol levels within the 19% to 21% limit, with Karnataka averaging 19.30%.
Since ESY 2014-15, the ethanol program saved over Rs 1.97 lakh crore in foreign exchange and replaced around 316 lakh metric tonnes of crude oil.
The initiative reduced CO2 emissions by nearly 952 lakh metric tonnes and transferred over Rs 1.66 lakh crore to domestic farmers.
During ESY 2025-26, OMCs procured 1,089 crore litres of ethanol and blended 1,134 crore litres into 5,673 crore litres of total petrol sales.

Between 2001 and 2003, India ran pilot projects in select states to test 5% ethanol blending in motor petrol.
The National Policy on Biofuels 2018 expanded feedstock options to include surplus food grains, damaged rice, and maize.
In 2021-2022, the government moved the target year for 20% ethanol blending from 2030 to 2025-26, based on the NITI Aayog Roadmap.
From 2023 to 2026, E20 fuel was rolled out commercially across retail stations under updated IS 17021:2018 standards.

The National Policy on Biofuels provided regulatory support, streamlined inter-state transport, and fixed feedstock-based pricing.
The government introduced Interest Subvention Schemes offering loan subsidies for setting up 1G and 2G ethanol plants.
Automated blending systems were installed at refinery depots to stop manual tampering of fuel proportions.
The Centre for High Technology (CHT) set up Quality Coordination Cells (QCC) to perform nationwide compliance testing.

State officials drew fuel samples without OMC presence, violating the 2005 Control Order and MDG 2024.
The state failed to provide parallel retention samples or detailed lab sheets to OMCs for counter-testing.
Test certificates used incomplete Gas Chromatography methods without following ASTM D4815/D6839 standards.
The reported samples showed lower fuel density between 0.742 and 0.749 g/cc, which contradicts physical laws because adding ethanol raises fuel density above 0.752 g/cc.

Activists claimed a blanket 10% drop in mileage, but official tests by ARAI and SIAM show only a 1% to 2% drop in E20-calibrated engines and 3% to 6% in older engines.
Claims of Rs 62,000 crore annual fuel losses are based on flawed assumptions about nationwide vehicle performance.
Activists alleged Rs 39,000 crore in vehicle repair costs, but data shows over 34 crore vehicles operate on E20 daily without systemic mechanical failures.
Allegations that retailers profit by over-blending are false because excess ethanol increases procurement costs for OMCs.

State authorities, OMCs, and accredited labs must conduct all fuel quality audits through joint verifiable sampling.
Automobile manufacturers should accelerate the production of E20-calibrated engines across all vehicle segments.
Depot-level automated blending logs and QCC test reports should be published on digital portals for transparency.
State legal metrology laboratories need standardized Gas Chromatography equipment and reference fuels to eliminate testing errors.

This debate highlights the need for aligned quality testing between state authorities and central standards.
Strict compliance with legal sampling protocols and joint audits will preserve consumer trust and support national biofuel targets.
