What is E20 fuel: How it can help in PM Narendra Modi’s Flex fuel vision


For years, India has made considerable attempts to promote greener fuel options, and one such innovation that has recently been unveiled is the E20 fuel. The fuel is a blend of 20% ethanol and 80% petrol, and it is projected to be less polluting while also reducing the government’s reliance on oil imports.

The Indian government has set a target of achieving 20% ethanol blending in petrol by 2025, with investments of up to 41,000 crore estimated to be spent to achieve this goal. The country hopes to reach the 10% ethanol blending objective by 2022, and the introduction of E20 fuel brings it one step closer to its sustainable energy goal of 2030.

The introduction of E20 fuel in Bengaluru is an important step towards pushing cleaner fuel solutions throughout the country. In the first phase, E20 fuel would be available in 15 cities throughout India through Indian Oil Corporation stores, two months ahead of the Centre’s initial deployment schedule for April. Fuel retailing would be expanded across the country during the following two years.

What is E20?

E20 gasoline is a mixture of 20% ethanol and 80% petrol. Ethanol, often known as ethyl alcohol, is a renewable organic molecule derived from corn, sugarcane, wheat, barley, and other grains. Blending ethanol with other fuels helps to reduce hazardous emissions such as nitrogen oxide, carbon monoxide (CO), and hydrocarbons (HC). As a result, E20 fuel is a good method to go green while also saving money.

Indian research into the appropriateness of utilizing E20 in existing vehicles discovered that metals and metal coatings were not affected by E20. Elastomers performed worse with E20 than with straight petrol. The study, conducted in 2014-15 by the Automotive Research Association of India (ARAI), Indian Institute of Petroleum (IIP), and Indian Oil Corporation (R&D), discovered that fuel economy declined by up to 6% (depending on the vehicle type).

When the engine is correctly tuned, joint experiments conducted by the Massachusetts Institute of Technology (MIT) and Honda R&D show that E20 can enhance relative efficiency by up to 20% when compared to regular petrol. Ford Motor Company trials indicated that an engine optimized for E20 fuel produced equivalent volumetric fuel economy (mileage) and range (kilometers traveled on a single fill) to standard gasoline while emitting 5% less CO2.

Since 2013-14, the ethanol blending program has experienced a sixfold rise in ethanol production capacity. The program’s accomplishments have not only increased India’s energy security but have also resulted in a slew of other advantages, including a reduction of 318 lakh metric tonnes of CO2 emissions and savings of almost Rs 54,000 crore in foreign exchange. As a result, around Rs 81,800 crore has been paid for ethanol supplies from 2014 to 2022, with more than Rs 49,000 crore transferred to farmers.

The Indian government has made E20 fuel available at 84 retail locations of Oil Marketing Companies throughout 11 states and union territories. The goal is to reach a total 20% ethanol blend by 2025, and oil marketing corporations are constructing 2G-3G ethanol plants to aid efforts. The Indian government’s Ethanol Blending program is a critical focal area for achieving energy independence.

What are the effects of E20 on your vehicle?

For quite some time, people have been debating whether E20 fuel is hazardous to engines. While there is no definitive answer to this question, drivers should be aware of the potential risks and benefits of using E20 fuel. While E20 fuel can increase performance in some vehicles due to its higher octane rating and lower emissions, it also has possible hazards and drawbacks that should be considered before switching.

One of the most serious issues with utilizing E20 fuel is its corrosive qualities. Certain engine materials, such as rubber seals, gaskets, and plastic components, can deteriorate when exposed to ethanol. If used incorrectly or in an unsuitable vehicle, this can cause engine damage. Furthermore, ethanol absorbs water faster than petrol, which might contribute to corrosion difficulties over time. Too much ethanol in a vehicle’s fuel system can also produce blockage, which can lead to engine failure or other issues.

Another big difficulty with utilizing E20 fuel is the effect it has on fuel economy. According to reports, using E20 gasoline in a car can reduce mileage by 6-7%, with higher amounts of ethanol mixing in petrol reducing fuel efficiency by 6-7%. This means that the gasoline your automobile used to travel 100 kilometers will now only get you 93-94 kilometers, a considerable decrease in fuel efficiency. This decrease in fuel efficiency may raise the total cost of ownership for automobiles transitioning from E10 to E20-compliant designs.

However, several automakers are considering technology advancements like lightweight to mitigate the impact on fuel economy. They are building cars with lighter materials to reduce total weight and hence improve fuel efficiency.

Furthermore, running E10-compliant vehicles on E20 fuel would cause corrosion of some engine components. This means that the rusted parts will have to be replaced, raising the expense of vehicle maintenance for owners. As a result, drivers considering utilizing E20 biofuel should conduct a preliminary study and communicate with their car maker to discover if their vehicle is compatible with E20 fuel.

To summarise, E20 fuel has both advantages and disadvantages. It can boost performance and lower emissions, but it can also damage engines if applied incorrectly, diminish fuel efficiency, and raise maintenance costs. Before making any decisions about their fuelling system requirements, vehicle owners should carefully evaluate these factors. To reduce the danger of engine damage or other problems associated with using this type of fuel blend, drivers should check with their vehicle manufacturer and conduct routine preventative maintenance procedures.

What are the benefits and drawbacks of using E20 fuel?

Many have applauded the Indian government’s move to adopt E20 gasoline, a blend of petrol and 20% ethanol derived from sugarcane and damaged plant grains. This article examines the benefits and drawbacks of this new fuel.


1. Pollution reduction: E20 fuel is noted for being less polluting. When employed on a large scale, this will assist to reduce pollutants, benefiting air quality and public health.

2. Reduced reliance on imports: India now imports 85% of its entire fuel, resulting in a massive cost for crude oil. The country will save a lot of money by adopting 20% ethanol blended fuel, reducing its reliance on fuel imports.
