What is E20 Petrol? Difference Between E20, E25 and E85 | Benefits and Drawbacks of Ethanol Blending

• India has achieved its target of 20% ethanol blending in petrol (E20 Petrol) ahead of schedule.
• The government is now moving towards E25 and E85 fuels as part of its long-term clean energy strategy.
• While higher ethanol blending is expected to reduce crude oil imports, improve farmers' income and lower carbon emissions, it has also raised concerns among vehicle owners regarding reduced mileage, engine compatibility and maintenance costs.
• This article explains what E20 petrol is, how ethanol blending works, why mileage decreases, what E25 and E85 are, how flex-fuel vehicles function, and what India can learn from Brazil's ethanol programme.

What is E20 Petrol ?

• E20 Petrol is a fuel blend consisting of 20% ethanol and 80% petrol.
• Ethanol is a renewable biofuel primarily produced from sugarcane, maize and other agricultural feedstocks.
• The objective of ethanol blending is to reduce petrol consumption, improve energy security and lower greenhouse gas emissions.

India's Ethanol Blending Programme

• India introduced the National Policy on Biofuels in 2009, setting a target of 20% ethanol blending in petrol by 2017.
• The target could not be achieved due to production and supply constraints.
• In recent years, the government significantly expanded ethanol production, enabling the country to move from E10 to E20 within just three years, much faster than originally planned.

Why is E20 Petrol in the News?

• India recently achieved its E20 petrol target five years ahead of schedule.
• In June 2026, the government launched E85 fuel and is now preparing to promote E25 fuel and flex-fuel vehicles.
• Since many vehicles on Indian roads were originally designed for E10 fuel, the rapid transition has sparked concerns over mileage loss and engine compatibility.

Why Does E20 Petrol Reduce Mileage ?

This is one of the most frequently asked questions.

The answer lies in the energy content of ethanol.

• Ethanol has a lower calorific value than petrol.
• It produces less energy when burned compared to the same quantity of petrol.
• As a result, engines require more fuel to generate the same amount of power.
• This leads to lower fuel efficiency (mileage), particularly in vehicles that were not originally designed for E20 fuel.

Major Concerns Associated with E20 Petrol

1. Reduced Fuel Efficiency :- Due to its lower energy density, E20 petrol may deliver fewer kilometres per litre compared to conventional petrol.

2. Impact on Older Engines :- Ethanol is hygroscopic, meaning it absorbs moisture from the atmosphere.

This can increase the risk of :

• Corrosion in metal components
• Damage to fuel pipes
• Deterioration of rubber seals
• Wear in older fuel systems

3. Cold Starting Issues :- Because of ethanol's combustion characteristics, some older vehicles may experience difficulty starting in extremely cold weather.

4. Lack of Consumer Choice :- At present, most fuel stations in India primarily supply E20 petrol, leaving consumers with limited options to choose lower ethanol blends.

Why is Ethanol Considered Environment-Friendly ?

The chemical formula of ethanol is C₂H₅OH, whereas petrol contains heavier hydrocarbons.

Using ethanol helps :

• Reduce carbon dioxide (CO₂) emissions.
• Lower dependence on fossil fuels.
• Increase demand for agricultural produce such as sugarcane and maize.
• Improve farmers' income.
• Strengthen India's energy security.

Why Does Mileage Drop Despite Ethanol's High Octane Rating ?

Ethanol has a Research Octane Number (RON) of around 108, which is significantly higher than regular petrol.

A higher octane rating :

• Reduces engine knocking.
• Improves combustion efficiency.
• Allows engines to operate at higher compression ratios.

However, because ethanol has lower energy density, existing engines cannot fully utilize these advantages, resulting in reduced mileage.

Future engines specifically designed for E20 or E85 may achieve better efficiency.

What are E25 and E85?

Following the successful rollout of E20, the government plans to promote higher ethanol blends.

• E25: 25% ethanol and 75% petrol.
• E85: 85% ethanol and 15% petrol.

These fuels are primarily intended for flex-fuel vehicles.

What are Flex-Fuel Vehicles ?

Flex-fuel vehicles are specially designed automobiles that can operate on different proportions of petrol and ethanol.

These vehicles use :

• Modified engines
• Ethanol-compatible fuel injectors
• Corrosion-resistant fuel systems
• Advanced electronic control systems

Why Will the Transition from E20 to E25 Be More Challenging ?

According to the automobile industry, adopting E25 will require :

• Recalibration of engines.
• Stronger fuel systems.
• Better corrosion-resistant materials.
• Fresh testing and homologation (official vehicle certification).

Experts believe that older vehicles and two-wheelers are likely to face the greatest challenges.

Why is Brazil's Ethanol Model Important ?

Brazil began its ethanol programme during the 1970s oil crisis.

Today, consumers in Brazil can choose between :

• Petrol blended with 27–35% ethanol, and
• E100 (100% hydrous ethanol).

The Brazilian government also offers price incentives for ethanol, making flex-fuel vehicles highly popular.

India can learn that higher ethanol blends become successful when consumers are offered :

• Multiple fuel choices,
• Attractive pricing,
• Vehicles specifically designed for higher ethanol content.

Benefits of E20 Petrol

• Reduces crude oil imports.
• Saves foreign exchange.
• Increases farmers' income.
• Promotes the biofuel industry.
• Lowers carbon emissions.
• Enhances India's energy security.

Drawbacks of E20 Petrol

• Reduced mileage in many vehicles.
• Potential corrosion in older engines.
• Higher maintenance costs.
• Not all vehicles are E20-compatible.
• Limited fuel choices for consumers.

Conclusion

• E20 petrol represents a significant step toward India's clean energy transition and energy security goals. 
• It has the potential to reduce dependence on imported crude oil, support farmers and lower greenhouse gas emissions. 
• However, before moving towards E25 and E85, India must ensure that vehicle technology, fuel infrastructure and consumer awareness are adequately developed. 
• Providing consumers with greater fuel choices and appropriate price incentives, similar to Brazil's successful ethanol model, will be crucial for the long-term success of higher ethanol blending.

The government has granted administrative approval for the project and will soon issue a tender and appoint an expert consultant. The aim is to preserve the original architecture of these historic gates while protecting their structure.

What is Char Kaman ?

• Char Kaman is a group of four grand ornamental gateways surrounding Hyderabad's famous Charminar. They were built during the Qutb Shahi period as entrances to the old city of Hyderabad.
• A large square and garden, called Char Kaman, was built at the entrance to the Qutb Shahi palace complex, located north of the Charminar. A beautiful water fountain called Gulzar Houz (Char-Su-Ka-Houz) was located in its center.

The Four Gates of Char Kaman

• The four gates are located on the four sides of Gulzar Hauz:
  • North: Machli Kaman
  • South: Charminar Kaman
  • East: Kali Kaman
  • West: Sher-e-Batil ki Kaman
• Three stories were built on either side of each Kaman, which served as quarters for the royal soldiers and security personnel.

History of Char Kaman

• Charminar was built by Muhammad Quli Qutb Shah, the fifth ruler of the Qutb Shahi dynasty, between 1589–1591.
• According to historians, Char Kaman was built around 1594, a few years after the construction of Charminar.
• Its purpose was to grand the entrance to the royal palace complex and to create a large public square for administrative activities.

The original names of the four arches

At the time of construction, these gates had different names than they do today.

How did they get their current names?

• Over time, the names of these gates changed, and today they are known by the following names:
• Machhli Kaman (North): A giant fish made of bamboo and paper was hung here on the occasion of the Lunar New Year.
• Charminar Kaman (South): This name is derived from its location facing the Charminar.
• Kali Kaman (East): It is also known as Shambhu Prasad's Kaman.
• Sher-e-Batil Kaman (West): It is believed to mean "Gate of the Lionhearted" or "Gate that Destroys Evil."

Historical Significance of the Char Kaman

• During the Qutb Shahi period, the Char Kaman was not only a gateway but also a major center of administrative activity.
• Royal officials and nobles visited here daily.
• Officials would leave their attendants in the royal courtyard located between the four gates and would go alone to meet the king.
• This area was the main entrance to the royal palace complex.

What will the restoration plan include?

• Under the government's proposed project:
  • Historic structures will be repaired.
  • Damaged areas will be conserved.
  • Original architecture and heritage features will be preserved.
  • Efforts will be made to repair damage caused by pollution and urbanization.

Significance of Char Kaman

• An excellent example of Qutb Shahi architecture.
• A historical landmark of the Charminar complex.
• An important part of Hyderabad's cultural heritage.
• An excellent example of medieval urban planning and architecture in India.
• ​​A monument of immense importance from the perspective of tourism and heritage conservation.

Conclusion

The Char Kaman are not just four gateways, but a precious relic of Hyderabad's glorious history, Qutub Shahi architecture, and urban planning. The Telangana government's restoration plan will significantly help preserve these historical monuments and safeguard their legacy for future generations.

India–Indonesia Strategic Partnership 2026: BrahMos, Astra Missiles, Critical Minerals & Sabang Port

Himalayan pangolins are considered independent species, not subspecies of the Chinese pangolin

Why in the news ?

• An international study recently published in the journal Communications Biology has re-recognized the Himalayan pangolin (Manis aurita) as an independent species, distinct from the Chinese pangolin (Manis pentadactyla). Researchers based this conclusion on extensive genomic and morphological analysis.
• Scientists believe this discovery will be crucial for the conservation of one of the world's most trafficked and critically endangered mammals.

Key Points

• The Himalayan pangolin is now recognized as an independent species, Manis aurita.
• It was previously considered a subspecies of the Chinese pangolin, Manis pentadactyla.
• The two species diverged approximately 1.8 million years ago due to climate change.
• The research was published in the journal Communications Biology.
• Major distribution in Nepal, South Tibet, and the northeastern states of India (especially Assam).
• Illegal wildlife trade and inbreeding are its major threats.

What's the whole matter ?

• For many decades, the Himalayan pangolin was considered a subspecies of the Chinese pangolin. It was classified based on the original specimen (lectotype) obtained from Nepal in 1836, but its actual taxonomic status was unclear.
• A team of international researchers performed DNA sequencing of the original specimen and compared it with modern genetic data and anatomy. The study confirmed that the Himalayan pangolin is a distinct and independent species.

How did the two species diverge ?

• According to research, the ancestors of the two species split into different regions during global climate change about 1.8 million years ago (Early Pleistocene Epoch).
• The western group evolved in the Himalayan region to become Manis aurita.
• The eastern group evolved in China and Southeast Asia to become Manis pentadactyla.
• This process is called allopatric speciation, in which geographical barriers cause the evolution of new species.

The Role of Climate Change

• According to the study, habitat in the Himalayan region became increasingly limited due to the extremely cold and dry climate during the Pleistocene.
• As a result,
  • The Himalayan pangolin population declined drastically.
  • Its habitat became unstable.
  • Genetic diversity was affected.
• Meanwhile, the coastal forests of southern China remained relatively stable, which made the Chinese pangolin population more secure.

Key Features of the Himalayan Pangolin

Research has found the Himalayan pangolin to differ from the Chinese pangolin in several ways.

Key Differences

• Additionally, significant differences were found in several genes associated with olfaction in both species.

Distribution in India

• The Himalayan pangolin has a limited natural distribution.
• This species is found in:
• Nepal
• South Tibet
• India's northeastern states
• Assam in particular
• According to researchers, the Brahmaputra Drainage and the Arakan Mountains played a key role in keeping the two species separate for millions of years.

Major Threats

1. Illegal Wildlife Trade

• The Himalayan pangolin is among the most trafficked mammals in the world.
• Its scales, meat, and other organs are used in the illegal wildlife trade and some traditional medicine systems.
• The study also found that illegal products derived from this species are reaching the market through formal supply chains.

2. Inbreeding

• Research found that overall, Himalayan pangolins have lower inbreeding than Chinese pangolins.
• However, significant inbreeding has been observed in the population around the Kathmandu Valley.
• This situation could lead to genetic weakness (Inbreeding Depression) in the future.

Researchers' Recommendations for Conservation

• Scientists have suggested that Manis aurita be included as an independent species in CITES Appendix-I.
• A complete ban on international commercial trade should be implemented.
• The new taxonomic identification should be promptly incorporated into global conservation policies.
• Illegal wildlife trafficking should be strictly monitored.
• Scientific conservation programs should be implemented to maintain genetic diversity.

About Pangolins

Scientific Classification

• Phylum: Chordata
• Class: Mammalia
• Order: Pholidota
• Family: Manidae
• Genus: Manis

Key Features

• The world's only fully scaled mammal.
• Main food: ants and termites.
• Highly developed sense of smell.
• Curls itself into a ball when threatened.
• Nocturnal and solitary.

What is CITES Appendix-I ?

• Appendix-I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) includes species that are at high risk of extinction.
• International commercial trade in these species is almost completely prohibited.

Conclusion

The recognition of the Himalayan pangolin as an independent species is a significant achievement in the field of biogeographical classification and wildlife conservation. This study demonstrates that climate change, geographic isolation, and genetic evolution played crucial roles in the evolution of this species. Furthermore, this new identification provides a basis for more effective conservation strategies for the Himalayan pangolin.

IBC vs PMLA: Key points, significance and impact of the historic NCLAT verdict

Why in the news ?

• Recently, the National Company Law Appellate Tribunal (NCLAT) delivered a significant and historic ruling. The court made it clear that if a company has amassed wealth through crime or fraud, it cannot be protected under the Insolvency and Bankruptcy Code (IBC).
• The tribunal stated in very strong terms, "Parliament has not made the IBC a 'holy Ganges' in which a company's criminal acts can be washed away and forgiven."

What is the matter ?

• This entire case involves a company called Siddhi Vinayak Logistics Limited:
• The company's owners (promoters) are accused of fraud, defrauding banks, and misappropriating funds worth approximately ₹1,600 crore
•  In 2017, the Enforcement Directorate (ED) took action and temporarily attached the company's assets under the Prevention of Money Laundering Act (PMLA).
• Shortly thereafter, the company became bankrupt and a moratorium was imposed on it under the IBC.

What is a 'moratorium' ?

• When a company is on the verge of bankruptcy, the court grants it a moratorium (relief period) for a period of time.
• During this period, no new cases can be filed against the company.
• Banks or creditors cannot sell the company's assets to recover their dues.
• Its purpose is to give the company a chance to get back on its feet.

Where did the conflict occur ?

• The liquidator overseeing the company's bankruptcy proceedings argued in court that the Enforcement Directorate (ED) cannot seize or confiscate the company's assets while the moratorium is in effect, as this would result in loss of funds for the banks.

Why the conflict between the two laws (IBC and PMLA) ?

• The objectives of both the laws are completely different from each other :

• When a property is acquired from fraudulent proceeds and the company goes bankrupt, then both the laws come face to face.

What did the NCLAT say in its decision ?

Clearing this conflict once and for all, the NCLAT made the following key points :

• Moratorium only on 'honest' assets: The Insolvency and Bankruptcy Code (IBC) moratorium only protects a company's legal and legitimate assets. It has no jurisdiction over assets earned through fraud or crime.
• National interest paramount: Even if banks or creditors receive a little less money in the insolvency process, the country's national interest against money laundering cannot be compromised.
• ED's action justified: The insolvency process cannot be used as a shield to prevent the ED from seizing scam assets.

Can bankruptcy courts (NCLT/NCLAT) stop ED action ?

• No. NCLAT clarified that bankruptcy courts (NCLT or NCLAT) have no authority to investigate whether ED's attachment is correct or incorrect.
• If anyone has a complaint about ED's action, they will have to approach the PMLA Special Court.

Can bankruptcy courts (NCLT/NCLAT) stop ED action ?

• No. NCLAT clarified that bankruptcy courts (NCLT or NCLAT) have no authority to investigate whether ED's attachment is correct or incorrect.
• If anyone has a complaint about ED's action, they will have to approach the PMLA Special Court.

Conclusion

This NCLAT decision is a major step towards cleaning up India's economic system. The message is clear: incurring business losses (for which the IBC exists) is one thing, but committing crimes and fraud (for which the PMLA exists) is quite another.

Doctrine of Per Incuriam: Meaning, Constitutional Basis, Supreme Court Judgment & Key Case Law

Why in News ?

• The Supreme Court recently clarified the circumstances under which a judicial decision can be declared per incuriam.

Constitutional and Jurisprudential Foundations

• The term per incuriam means "through lack of care" and applies to judgments delivered in ignorance of binding law.
• It is closely linked to the doctrine of stare decisis, which promotes certainty through judicial precedents.
• The doctrine operates as an exception to Article 141 of the Constitution, under which Supreme Court decisions are binding.

Scope of Application

• A judgment may be declared per incuriam if it ignores a relevant statute or a binding precedent.
• The doctrine applies only to ratio decidendi and not to obiter dicta.
• Such judgments are not treated as binding precedents due to incorrect legal interpretation.

Supreme Court Clarifications

• A judgment is per incuriam when its ratio conflicts with an earlier decision of an equal or larger bench.
• Overlooking a relevant statutory provision, rule, or regulation can also attract the doctrine.
• The binding force of a judgment depends on bench strength rather than the number of judges supporting a view.
• A co-equal bench disagreeing with an earlier decision must refer the matter to a larger bench.

Important Case Law

• In State of Assam v. Ripa Sarma, the Court held that a judgment ignoring decisions of similar or larger benches would be per incuriam.
