The rollout of 20% ethanol-blended petrol (E20) may cause a small dip in vehicle mileage, but experts say the wider benefits for India’s economy, farmers, and environment far outweigh the marginal impact on fuel efficiency.

Mileage Impact and Vehicle Safety

According to the Automotive Research Association of India (ARAI), E20 fuel typically reduces mileage by only 2–4%, depending on the vehicle type. This drop is due to ethanol’s lower calorific value, which is about 30–35% less than petrol.

Auto industry body SIAM (Society of Indian Automobile Manufacturers) stressed that consumer concerns about higher efficiency losses or warranty issues are misplaced. “Not a single vehicle breakdown has been reported due to E20. Warranties will be honoured without conditions,” SIAM Executive Director P.K. Banerjee said, dismissing claims of a 20–50% fall in efficiency as misinformation.

ARAI studies from 2016 and 2021 also confirmed no adverse impact from ethanol blending.

Benefits for Farmers and Economy

Beyond the minor fuel efficiency drop, officials highlighted the major economic and social benefits. Ethanol procurement worth ₹40,000 crore has already been paid to farmers in 2025, boosting rural incomes and prosperity, according to the Federation of Indian Petroleum Industry (FIPI).

Since 2014-15, ethanol blending has helped India:

• Substitute 245 lakh metric tonnes (LMT) of crude oil
• Save ₹1.44 lakh crore in foreign exchange
• Cut 763 LMT of carbon dioxide emissions

Toyota Kirloskar Motor’s Executive Vice President Vikram Gulati said ethanol blending keeps money within India. “The money that would have gone abroad for crude imports is now going to farmers. This makes them stronger economically and helps drive consumption in the domestic economy,” he explained.

Towards Energy Independence

Industry leaders believe E20 is key to India’s smooth transition towards sustainability. By reducing crude oil imports, cutting forex outflow, and directly benefiting farmers, the program strengthens India’s push for self-reliance in energy, technology, and raw materials.
