E20 Petrol Debate Gets Heated Again… Government Defends Ethanol Fuel, Cites Maruti Suzuki & Hero MotoCorp Data

The debate around E20 petrol has intensified once again, with the Ministry of Petroleum and Natural Gas releasing a detailed set of Frequently Asked Questions (FAQs) defending India’s ethanol blending programme and addressing concerns raised by vehicle owners and industry observers.

The ministry said the clarification was issued after continued questions regarding ethanol-blended petrol, despite previous explanations and statements from automobile manufacturers.

According to the government, the Ethanol Blended Petrol (EBP) Programme has been developed after years of consultation with automobile companies, testing agencies and research organisations, and is aimed at reducing India’s dependence on imported crude oil while supporting cleaner energy alternatives.

Government Says Ethanol Blending Was Not Introduced Suddenly

Responding to criticism that India moved too quickly towards E20 petrol, the ministry stated that ethanol is not a new fuel technology and has been used internationally for decades.

The government highlighted that India’s ethanol blending journey began much earlier, with a pilot programme launched in 2001, followed by a formal policy framework in 2004. The rollout of E5 petrol, containing 5% ethanol blending, began across several states in 2006.

However, the ministry said ethanol blending remained limited for years due to challenges in ethanol production capacity.

It stated that blending levels remained around 1.5% until 2014, after which the government introduced measures to expand production through the National Policy on Biofuels launched in 2018.

The ministry said multiple government departments worked together to improve ethanol availability, develop infrastructure and encourage investment in the sector.

Why Can’t Consumers Choose Between Pure Petrol, E10 and E20?

One of the major concerns raised by consumers has been the lack of a choice between different petrol blends.

Addressing this issue, the ministry said automobile manufacturers were involved in discussions before increasing ethanol blending levels.

It stated that consultations for E10 compatibility began during 2020-21, and India achieved its E10 target ahead of schedule in 2022.

For E20 petrol, the government said extensive discussions were conducted with vehicle manufacturers, component suppliers, testing organisations and research institutions before implementation.

The ministry argued that manufacturers would not have supported E20 if they had concerns about vehicle safety or durability.

It said companies are continuing to honour warranties because they were part of the development and testing process.

Maruti Suzuki and Hero MotoCorp Data Cited on Older Vehicles

To address concerns about older vehicles, the government referred to real-world service data from major automobile manufacturers.

The ministry cited Maruti Suzuki, stating that the company serviced approximately 2.84 crore vehicles during FY 2025-26, including around 1.5 crore older vehicles that were not specifically E20-certified.

According to the ministry, Maruti Suzuki reported no major E20-related issues such as corrosion, abnormal engine wear or reduced component life.

The government also pointed to similar field experience reported by Hero MotoCorp.

The ministry described this data as practical evidence from millions of vehicles rather than isolated individual complaints.

E20 May Reduce Mileage Slightly, Government Says

The government acknowledged that some vehicles could experience a 3-5% reduction in fuel efficiency after switching to E20 petrol.

However, it argued that mileage is only one factor when evaluating fuel quality.

According to the ministry, E20 offers benefits such as:

• Higher octane rating
• Improved anti-knock performance
• Faster combustion
• Smoother acceleration
• Cleaner engine operation

The government also claimed that E20 can significantly reduce lifecycle carbon emissions and contribute to lower particulate emissions.

Why Not Supply Multiple Petrol Options Nationwide?

The ministry also addressed demands for separate availability of pure petrol, E10 and E20.

It said maintaining separate fuel supply chains across India’s massive network of more than one lakh fuel stations would create major logistical challenges, increase costs and complicate inventory management.

The government explained that premium petrol products are different because they are specialised fuels sold in limited quantities, unlike nationwide base fuel categories.

Government Highlights Economic Benefits of E20

The ministry also pointed towards the economic impact of ethanol production.

It stated that public sector banks have supported nearly ₹1 lakh crore per year in investments related to ethanol production and infrastructure.

The government argued that reversing the ethanol programme would affect investments made by farmers, cooperatives, entrepreneurs, financial institutions and energy companies.

According to the ministry, the E20 initiative aims to balance several objectives, including energy security, environmental protection, farmer income growth and reducing India’s crude oil import dependency.

E20 Debate Continues as India Moves Towards Cleaner Fuels

The government’s latest clarification comes amid ongoing discussions among consumers, automobile experts and policymakers about the benefits and challenges of ethanol-blended petrol.

While supporters highlight reduced oil imports, cleaner emissions and benefits for farmers, some vehicle owners continue to seek more transparency and long-term studies on vehicle performance.

For now, the government remains firm on its position that E20 petrol is a scientifically tested fuel standard and that India should continue moving forward with ethanol adoption rather than reversing the policy.
