Key Points

The Petroleum Ministry refutes claims that E20 petrol drastically reduces fuel efficiency, stating the impact is marginal. Ethanol blending improves engine performance due to its higher octane rating. India has saved Rs 1.4 lakh crore in oil imports and reduced CO2 emissions significantly. The government assures that E20-compliant vehicles are already available and safe for use.

Key Points: Petroleum Ministry Says E20 Petrol Improves Engine Performance

  • E20 petrol causes only 1-6% fuel efficiency drop
  • Ethanol blending cuts CO2 emissions by up to 65%
  • Higher octane number improves engine performance
  • India saved Rs 1.4 lakh crore in oil imports

E20 Petrol does not cause drastic drop in fuel efficiency, even improves engine performance: Petroleum Ministry

Govt clarifies E20 petrol has minimal impact on fuel efficiency, boosts engine performance, and reduces emissions—debunking social media myths.

"Vehicles tuned for E20 deliver even higher performance – Petroleum Ministry"

New Delhi, August 5

The Ministry of Petroleum and Natural Gas has dismissed recent claims circulating on social media that E20 petrol, petrol blended with 20 per cent ethanol, causes a drastic drop in fuel efficiency.

In a detailed statement, the ministry said such allegations are factually incorrect and not backed by scientific analysis or expert opinion.

The ministry clarified that while ethanol has lower energy density than petrol, the impact on fuel efficiency is only marginal.

In a social media post the ministry stated that "the allegation that E20 leads to drastic drop in fuel efficiency is factually incorrect".

The ministry stated that for vehicles designed for E10 and calibrated for E20, mileage may drop by just 1-2 per cent, while in other vehicles, it could be around 3-6 per cent.

This drop can be further reduced with better engine tuning and use of E20-compatible parts, which leading automobile manufacturers have already adopted.

The Society of Indian Automobile Manufacturers (SIAM) has confirmed that E20-compliant vehicles with upgraded components have been available since April 2023.

On the issue of material corrosion, the ministry stated that safety standards for E20 are well-established through BIS specifications and Automotive Industry Standards.

In some older vehicles, minor replacements such as rubber parts or gaskets may be needed after 20,000 to 30,000 kms, but these are inexpensive and usually done during regular servicing.

Addressing environmental concerns, the ministry highlighted that ethanol is a renewable fuel that helps reduce CO2 emissions. India's ethanol is now produced not only from sugarcane but also from surplus rice, maize, damaged foodgrains, and agricultural waste, especially under the push for second-generation (2G) biofuels.

A study by NITI Aayog found that ethanol made from sugarcane and maize emits 65 per cent and 50 per cent less greenhouse gases, respectively, compared to petrol.

The ministry also emphasized the benefits of ethanol in improving vehicle performance. Ethanol has a higher octane number (~108.5) than petrol (~84.4), which helps improve engine performance and ride quality in modern vehicles.

The ministry stated "Vehicles tuned for E20 (having increased RON) deliver even higher performance".

Additionally, its higher heat of vaporization lowers the intake manifold temperature, increasing air-fuel mixture density and engine efficiency.

The government noted that ethanol blending also boosts energy security by reducing crude oil imports. Since 2014-15, India has saved over Rs. 1.40 lakh crore in foreign exchange due to ethanol substitution. It has also led to payments of over Rs. 1.20 lakh crore to farmers, supporting rural incomes and employment. Ethanol blending has helped reduce carbon dioxide emissions by 700 lakh tonnes.

The ministry concluded that the concerns about E20 harming vehicles or causing consumer hardship are not based on facts.

While I appreciate the government's efforts towards cleaner fuel, I'm still concerned about the long-term effects on older vehicles. My 2012 Swift might need modifications and that means extra expenses. Why can't they offer some subsidy for these upgrades?

This is great news for both farmers and the environment! Using agricultural waste for ethanol production is a win-win solution. More income for farmers and less pollution for our cities. Bharat should be proud of this initiative 🇮🇳

I appreciate the detailed explanation but wish the ministry would share more real-world test data. The 1-6% efficiency drop sounds minimal, but over years of usage and lakhs of kilometers, the cost difference might add up significantly for commercial vehicle owners.

The foreign exchange savings are impressive! ₹1.4 lakh crore saved means more money for infrastructure and development. We need to support indigenous solutions like this instead of always depending on imported crude oil. Jai Hind!

My husband is an auto engineer and he says the higher octane number is actually beneficial for performance cars. Maybe we'll see Indian tuners taking advantage of E20 for better racing performance soon! 🚗💨
