Union Petroleum and Natural Gas Minister Hardeep Singh Puri has rejected concerns surrounding the government’s E20 petrol programme, describing the controversy as a result of “misreporting and misinterpretation”. The minister said automobile manufacturers have not raised concerns over the use of E20 fuel and questioned why the issue has resurfaced after the blended fuel has already been in use across the country for more than a year.
The government has been expanding ethanol blending in petrol as part of its broader strategy to reduce dependence on imported crude oil, lower carbon emissions and support India’s agricultural sector. E20 petrol contains 20 per cent ethanol and has been rolled out after compatibility assessments involving vehicle manufacturers and research institutions.
Puri rejects claims over E20 fuel
Responding to criticism circulating on social media, Puri said there is no evidence to support claims that E20 petrol damages vehicle engines or creates operational problems. He noted that millions of vehicles are already running on the fuel without widespread issues being reported.
According to the minister, nearly 20 crore two-wheelers and around 20 lakh four-wheelers are using E20 fuel. He added that vehicle manufacturers as well as service professionals have consistently indicated that they have not experienced any significant difficulties with the ethanol blend.
Questioning the timing of the debate, Puri said the fuel has already been available for a considerable period, making the sudden wave of criticism difficult to understand.
Government says E20 has been in use for over a year
The minister highlighted that India had already been using E15 fuel for more than three years before transitioning to E20. He said E20 petrol has been available nationwide since April 2025, meaning it has already completed more than a year of public use.
Puri also clarified that while discussions around higher ethanol blends such as E25 continue, the government has not announced any immediate rollout. He said testing is currently underway, and any future decision will be based on scientific evaluation and consultations with stakeholders, including automobile manufacturers.
Government says future ethanol blends will undergo testing
Addressing speculation about higher ethanol blends, Puri said the government is taking a cautious approach before introducing E25 petrol. He stressed that ongoing tests will be completed first, after which the findings will be reviewed before any policy decision is taken.
The minister said discussions with automobile manufacturers and other stakeholders would be an important part of the process before moving ahead with any higher ethanol blend.
“I neither make the cars nor the fuel. The car manufacturers are comfortable with the E20 fuel. Each one of them has made a statement,” Puri said, reiterating that vehicle makers have already expressed confidence in the current fuel blend.
He also noted that the rollout of E85 fuel would take additional time as it would require supporting infrastructure, including suitable fuel dispensing facilities at petrol pumps.
Government continues to promote ethanol blending
The Centre has identified ethanol blending as a key component of its energy transition strategy. Besides reducing India’s dependence on imported crude oil, the programme is intended to cut vehicular emissions and create additional demand for agricultural produce used in ethanol production.
The government has gradually increased ethanol blending targets over the past few years while working with automobile manufacturers and research agencies to ensure vehicle compatibility with higher ethanol blends.
Puri had earlier stated that the government welcomes constructive criticism of its policies but would not accept what he described as rumours regarding biofuel blending. His latest remarks come amid renewed social media discussions claiming that E20 fuel reduces vehicle mileage or causes engine-related issues.
Reiterating the government’s position, the minister said existing data and feedback from manufacturers do not indicate widespread problems with E20 petrol, adding that any future decisions on higher ethanol blends would continue to be based on testing, scientific assessment and stakeholder consultations.
