Read or download the official PDF of this gazette notification issued by the Ministry of Petroleum and Natural Gas on 30th July 2026. Classified under Press Release.
Executive Summary
The Ministry of Petroleum & Natural Gas has implemented the Ethanol Blended Petrol (EBP) Programme through a scientifically validated, phased rollout involving extensive stakeholder consultation. Research and real-world data from over 23 crore vehicles confirm that E20 fuel is safe, maintains engine durability, and does not adversely impact legacy vehicles. As of July 2026, manufacturers continue to honor warranties, reporting no widespread evidence of engine failure or abnormal wear attributed to the blend.
Key Points / Main Content
Scientific Validation and Testing
Comprehensive laboratory studies and field trials were conducted by ARAI, SIAM, IOCL, and IIP.
Testing parameters included engine durability, drivability, startability, corrosion resistance, material compatibility, emissions, and fuel efficiency.
E20 fuel is confirmed safe for use under prescribed standards and matches international-standard validations.
Performance and Environmental Benefits
E20 improves vehicle acceleration and ride quality compared to standard petrol.
The higher octane number of ethanol supports modern high-compression engines.
Increased heat of vaporization improves combustion efficiency while simultaneously reducing carbon emissions.
Impact on Legacy Vehicles
Studies establish that older "legacy" vehicles do not exhibit significant performance variations or abnormal wear and tear when using E20.
Data from FY 2025-26 shows that approximately 1.5 crore vehicles not originally certified for E20 were serviced with no reports of fuel-linked corrosion or component life reduction.
E15+ blends have been used for over three-and-a-half years, and E19-E20 for over two-and-a-half years without verified evidence of widespread engine failure.
Industry and Government Assessment
More than 20 crore two-wheelers and 3 crore cars currently operate on ethanol blends.
Automobile manufacturers have validated E20 for older vehicles and continue to honor all warranty obligations.
The assessment is based on large-scale nationwide implementation involving approximately 8 crore daily vehicle visits to retail outlets.
Impact Analysis
Automobile Manufacturers (OEMs)Impact
OEMs are seeing no significant increase in service issues or component failures despite the use of higher ethanol blends in both new and older vehicle models.
Action Required
Continue to monitor vehicle service data and honor warranty obligations for vehicles utilizing E20 fuel.
Vehicle Owners / ConsumersImpact
Consumers experience improved engine performance, better ride quality, and reduced emissions without the risk of abnormal engine wear or voided warranties.
Action Required
Continue using E20 fuel in accordance with prescribed standards for both new and legacy petrol vehicles.
Testing and Technical Agencies (ARAI, SIAM, IIP)Impact
These bodies are responsible for the ongoing scientific integrity and safety validation of the EBP Programme.
Action Required
Maintain rigorous international-standard testing and provide data-driven support for the continued rollout of higher ethanol blends.
Oil Marketing Companies (OMCs)Impact
OMCs are central to the nationwide distribution and implementation of the phased E20 rollout.
Action Required
Ensure the consistent supply and quality of E20 fuel at retail outlets to meet the needs of the approximately 8 crore vehicles visiting daily.

E20 ROLLOUT BASED ON SCIENTIFIC
VALIDATION AND EXTENSIVE STAKEHOLDER
CONSULTATION
प्रव तथ: 30 JUL 2026 3:04PM by PIB Delhi
The Ethanol Blended Petrol (EBP) Programme has been implemented through a phased, scientifically
validated and consultative process involving NITI Aayog, automobile manufacturers, Oil Marketing
Companies (OMCs), Automotive Research Association of India (ARAI), Society of Indian Automobile
Manufacturers (SIAM), Indian Institute of Petroleum (IIP) and other technical institutions.
The rollout of higher ethanol blends was undertaken only after extensive consultation with automobile
manufacturers, SIAM, ARAI, component manufacturers, testing agencies and Oil Marketing Companies
(OMCs).
Extensive laboratory studies and field trials conducted by ARAI, SIAM, IOCL, IIP and automobile
manufacturers covering parameters such as engine durability, drivability, startability, corrosion resistance,
material compatibility, emissions and fuel efficiency have confirmed that E20 is safe for use under
prescribed standards.
These studies also established that legacy vehicles do not exhibit any significant variation in performance
or abnormal wear and tear due to E20. These extensive laboratory studies, field validation and real-world
operating experience have not established any widespread adverse impact on vehicle performance due to
E20 fuel.
The Government's assessment is based not only on laboratory research but also on large-scale experience
after nationwide implementation. India witnesses approximately 8 crore vehicles visiting retail outlets
every day (around 80% petrol vehicles).
This is evident from the fact that E15+ blended petrol has been in widespread use for over three-and-a-half
years and E19-E20 fuel for over two-and-a-half years. More than 20 crore two-wheelers and over 3 crore
petrol cars have been operating on these blends without any verified evidence of widespread engine failure
or vehicle breakdown attributable to ethanol blending. Manufacturer service data confirm that there is no
abnormal corrosion, wear or reduction in vehicle life due to E20 fuel. Manufacturers continue to honour
warranty obligations for vehicles using E20 fuel, providing further confidence in its safety and reliability.
A leading OEM serviced 2.84 crore vehicles during FY 2025-26, including approximately 1.5 crore
vehicles that were not originally certified as E20-compatible, and reported no E20-linked corrosion,
abnormal wear or reduction in component life. A leading 2-wheeler company has reported similar field
experience. One OEM recently stated that data from 1.4 crore E20-operated vehicles tracked over an
extended period showed no evidence of ethanol-induced corrosion. ARAI reaffirmed that vehicles undergo
rigorous international-standard validation before reaching consumers.Automobile manufacturers, component suppliers, SIAM, ARAI, testing agencies and Oil Marketing
Companies were associated with every stage of the scientific evaluation and phased rollout of E20. E20
was introduced only after successful validation of fuel systems, engine durability, drivability, material
compatibility and emissions performance. These studies did not reveal any significant adverse impact on
performance, durability or material compatibility in legacy vehicles under the prescribed operating
conditions. Had automobile manufacturers not been fully satisfied with the results, they would neither
have validated E20 fuel for older vehicles nor honoured warranty obligations.
According to SIAM and ARAI, E20 improves acceleration and ride quality while reducing carbon
emissions. Ethanol's higher-octane number supports modern high-compression engines and its higher heat
of vaporisation improves combustion efficiency.

NATURAL GAS SHRI SURESH GOPI, in a written reply in Lok Sabha today.
