E20 petrol may cut mileage by up to 5%

The Centre has admitted that vehicles using E20 petrol could see their fuel efficiency drop by 3% to 5% compared with regular petrol. However, it says the cleaner fuel offers long-term benefits by reducing pollution and cutting India’s dependence on imported crude oil.

According to the Ministry of Petroleum and Natural Gas, ethanol contains less energy than petrol, which explains the slight reduction in mileage. While motorists may need a little more fuel to cover the same distance, the government believes the impact will be limited for most users.

E20 fuel, a blend of 20% ethanol and 80% petrol, is a key part of India’s strategy to promote cleaner transport. Officials say it produces lower emissions, helping improve air quality and reduce the country’s carbon footprint.

The government also highlighted the economic benefits of ethanol blending. Higher ethanol production creates demand for crops such as sugarcane and maize, providing additional income opportunities for farmers while reducing India’s fuel import bill.

Motorists will continue to have the option of using lower ethanol blends depending on their vehicle’s compatibility. The Centre has advised owners of older vehicles to follow manufacturers’ recommendations before switching to E20 fuel.

Despite concerns over mileage, the government says the environmental and economic gains outweigh the small loss in fuel efficiency. It plans to continue expanding ethanol blending as part of India’s clean energy transition while ensuring consumers have suitable fuel choices.

India makes E20 petrol mandatory nationwide

Starting April 1, 2026, every petrol pump across India will sell E20 petrol, fuel blended with 20% ethanol. The decision, announced by the Ministry of Petroleum and Natural Gas, marks a major change in the fuel Indians use every day.

For millions of motorists, the shift may go largely unnoticed at the pump. But behind the scenes, it reflects India’s push to cut pollution, reduce crude oil imports and support farmers who produce crops used to make ethanol, such as sugarcane and maize.

Ethanol is a biofuel made from plant-based materials. Blending it with petrol helps lower harmful emissions from vehicles. Officials say the move will help India reduce its carbon footprint while also saving foreign exchange by importing less crude oil.

Under the new rule, all petrol sold must meet a minimum standard of RON 95, which refers to fuel quality and engine performance. Higher RON fuel reduces engine knocking and supports smoother functioning. Most cars manufactured in recent years are already compatible with E20 fuel.

However, owners of older vehicles may have concerns. Experts say while older cars can generally run on E20, there could be a slight drop in fuel efficiency. Automobile companies have gradually upgraded engines to handle higher ethanol blends, and consumers are being advised to check their vehicle manuals for compatibility.

For farmers, the policy offers a potential boost in income. Increased demand for ethanol means higher demand for crops used in its production. For the government, it is also a step toward energy security and reduced dependence on volatile global oil markets.

While drivers may simply notice a new label at fuel stations, the change represents a broader shift in how India balances environmental responsibility, economic growth and everyday mobility.
