It was highlighted that ethanol blending has been a measured, scientifically driven, step-by-step process, and vehicle owners were reassured that E20 fuel poses no cause for concern.
Mr Vikram Gulati, Country Head & Executive Vice President, Toyota Kirloskar Motor, said the automotive industry is among the most strongly regulated sectors, with vehicles undergoing rigorous testing and certification by independent, globally accredited agencies before and after market introduction.
He described ethanol as a high-performance, clean fuel used since the early 1900s, including in Formula racing. He added that the decision to move to E20 was made only after rigorous testing on older vehicles, and clarified that the recently launched E85 dispensing stations are intended exclusively for flex-fuel vehicles, signalling the direction of future policy.
On questions regarding the independence of testing agencies, Mr Gulati clarified that testing protocols are not set in India alone; India is a party to UNECE, testing procedures are internationally standardised, and testing agencies are accredited, globally compliant, and undertake testing for exported vehicles. He stated that these protocols cannot be compromised.
Mr Rahul Bharti, Senior Executive Officer, Corporate Affairs, Maruti Suzuki, gave a “statement of confidence” to customers, stating that vehicles designed for E10 have been tested with E20 fuel across all parameters and found to have no areas of concern.
He informed that of the 2.84 crore cars serviced by Maruti Suzuki in FY 2025-26, more than 1.5 crore were over three years old and hence not E20-certified, and no E20-related issues of corrosion, wear and tear or damage to component life were reported from the field.
On mileage, Mr Bharti stated that the calorific value of E20 is lower than that of E10 by about 3 to 3.5 per cent, and the mileage impact is limited to this extent.
Illustrating this, he said that for a car giving 20 km per litre, the impact works out to roughly 0.6 km per litre, whereas factors such as tyre pressure, driving pattern, correct gear usage, acceleration, braking, and maintenance cause far greater variation in mileage.
This loss in mileage is more than compensated for by better acceleration, better anti-knock, and far less pollution with ethanol compared to pure petrol.
He clarified that vehicles are designed with safety factors well beyond E20 compliance, and that no retrofit kit is being offered on the market; such solutions are currently confined to R&D.
Ms Vartika Shukla, Former Chairman and Managing Director, Engineers India Limited (EIL), said that the ethanol blending programme was structured through deliberation with all stakeholders and is supported by scientific evidence and extensive testing by automotive manufacturers, in line with global best practices.
She noted that E20 fuel conforms to the BIS standard and BS-VI emission norms and is uniformly available across retail outlets in the country. She added that several countries have used ethanol blends for many years.
Mr Ashutosh Varma, Chief Business Officer, Hero MotoCorp, said that, as one of the world’s largest two-wheeler manufacturers, the company has analysed extensive service data and found no instances of more serious damage in vehicles running on E20 compared with earlier fuels.
The panel concluded by reaffirming the industry’s collective confidence in the ethanol blending programme and its commitment to addressing consumer queries with transparency.
