Will E20 Petrol Increase Fuel Prices? Government Says Delhi Petrol Could Have Hit ₹125/Litre Without Ethanol

India's ethanol blending programme has once again become the centre of debate after the government claimed that petrol prices in Delhi could have touched ₹125 per litre if ethanol had not been blended with petrol during the recent surge in global crude oil prices. According to the Ministry of Petroleum and Natural Gas, blending ethanol with petrol helped shield consumers from the full impact of expensive crude oil when international prices climbed to nearly $135 per barrel.

At the same time, the rollout of E20 petrol, which contains 20% ethanol and 80% petrol, continues to generate discussion among vehicle owners over mileage, maintenance, and compatibility with older vehicles.

Government Says Ethanol Helped Control Petrol Prices

Defending the ethanol blending programme, the Petroleum Ministry stated that domestic ethanol procurement played a crucial role in limiting retail fuel prices.

According to the government, if Indian Oil Marketing Companies had relied entirely on imported crude oil without ethanol blending, petrol prices in Delhi could have reached approximately ₹125 per litre during the peak of the global crude oil crisis.

Instead, consumers paid around ₹94.77 per litre, as ethanol formed nearly 20% of every litre of petrol, reducing dependence on expensive imported crude oil.

Why Ethanol Blending Makes a Difference

Ethanol is produced domestically from agricultural feedstocks such as sugarcane and certain grains. Unlike crude oil, which is subject to international price fluctuations, ethanol is purchased at pre-determined domestic prices.

By replacing a portion of petrol with locally produced ethanol, India reduces its overall import bill while protecting consumers from sudden spikes in global crude prices.

The government says this strategy not only improves energy security but also supports Indian farmers and reduces foreign exchange expenditure.

Retail Fuel Prices Remained Stable During the Crisis

The Ministry highlighted that despite significant volatility in global crude oil markets following the West Asia conflict, petrol and diesel prices in India remained unchanged for nearly 75 days.

Only later were petrol prices increased by ₹7.50 per litre.

According to official figures, E20 petrol currently costs ₹102.12 per litre in Delhi, while premium 100-octane petrol is priced at ₹169 per litre.

Government Rejects Claims Over Foodgrain Diversion

The ethanol programme has faced criticism from some groups alleging that food grains meant for public welfare schemes are being diverted for ethanol production.

The Petroleum Ministry has strongly denied these allegations.

Officials clarified that subsidised rice supplied through the Food Corporation of India (FCI) is not being diverted to support ethanol manufacturing, and rejected claims that food meant for economically weaker sections is being used for fuel production.

Will E20 Petrol Reduce Mileage?

While supporting ethanol blending, the government has also acknowledged that E20 petrol may slightly reduce fuel efficiency.

Road Transport and Highways Minister Nitin Gadkari informed Parliament that studies conducted by the Automotive Research Association of India (ARAI), Society of Indian Automobile Manufacturers (SIAM) and Indian Oil Corporation (IOCL) found that vehicles running on E20 fuel may experience a mileage reduction of approximately 2% to 6%.

The actual impact depends on factors such as the vehicle's age, engine type, and overall condition.

Older Vehicles May Need Minor Modifications

Another concern relates to older vehicles, particularly those built under BS-III emission norms.

According to the government, E20 petrol does not damage engines. However, some rubber components used in older fuel systems may wear out faster and could require replacement over time.

Newer vehicles manufactured to support E20 fuel are generally designed with compatible materials and are expected to operate without major issues.

Automobile manufacturers also continue to honour warranty claims for vehicles officially certified as E20-compatible.

What Are the Benefits of E20 Fuel?

Apart from reducing India's dependence on imported crude oil, ethanol-blended petrol offers several environmental and performance-related benefits.

Government studies indicate that E20 fuel can:

• Lower carbon emissions by nearly 30%
• Improve engine acceleration
• Deliver smoother driving performance
• Support cleaner fuel combustion
• Strengthen India's energy security

These advantages form the basis of the government's long-term transition towards cleaner transportation fuels.

Why Is the E20 Programme Still Controversial?

Despite the government's support, E20 petrol continues to face criticism from some consumers and opposition parties.

The main concerns include:

• Reduced fuel efficiency
• Higher long-term maintenance costs
• Compatibility with older vehicles
• Possible replacement of rubber fuel-system components
• Confusion regarding warranty and servicing

Many vehicle owners remain cautious, particularly those driving older models that were not originally designed for ethanol-blended fuels.

What Does This Mean for Vehicle Owners?

For owners of newer vehicles, especially those manufactured in recent years, E20 compatibility has largely been incorporated into engine design.

Owners of older vehicles should consult their vehicle manufacturer regarding E20 compatibility and inspect fuel-system components periodically if they regularly use ethanol-blended petrol.

Following the manufacturer's recommendations remains the safest approach as India gradually expands the availability of E20 fuel nationwide.

Final Thoughts

India's ethanol blending programme has become a key pillar of the country's energy strategy. The government argues that blending 20% ethanol with petrol prevented fuel prices from soaring to nearly ₹125 per litre during the recent global crude oil surge, helping consumers while reducing dependence on imported oil. At the same time, officials acknowledge that E20 petrol may reduce mileage by 2% to 6% and may require minor modifications for some older vehicles. As the nationwide rollout continues, consumers will need to balance the short-term impact on fuel efficiency with the programme's broader goals of lower emissions, greater energy security, and long-term price stability.
