Government Debunks E20 Petrol Myths, Says Ethanol Blend Is Safe for Vehicles

The Indian government has dismissed a series of viral social media claims about E20 petrol, saying the fuel is safe for vehicles and does not damage engines, reduce warranty coverage, or affect insurance. The Ministry of Petroleum and Natural Gas said the E20 programme is backed by scientific research and global experience, urging motorists not to be misled by misinformation.

E20 petrol contains up to 20% ethanol blended with petrol and is part of India's strategy to reduce dependence on imported crude oil and promote cleaner fuels. Recent social media posts claimed that the fuel causes engine damage, significantly lowers mileage, wastes large amounts of water during production, and even attracts insects because of its sugar content.

Responding to these claims, the ministry issued a detailed clarification covering ten key points.

The government said the claim that producing one litre of ethanol requires 10,000 litres of water is incorrect. According to the ministry, ethanol plants use only around 3–5 litres of processed water per litre of ethanol, with many facilities recycling water through Zero Liquid Discharge (ZLD) systems.

It also stressed that E20 is not a new experiment. Countries including the United States, Brazil, Canada, Japan, Thailand and several European nations have been using ethanol-blended fuel for years.

On concerns over engine performance, the ministry cited studies by the Automotive Research Association of India (ARAI) and other agencies, which found no major negative impact on vehicle performance. However, some older vehicles may require replacement of certain rubber components to ensure compatibility.

The ministry said mileage tests showed only a marginal difference, with no significant impact on driving performance. It also clarified that vehicles designed or approved for E20 fuel will not lose warranty or insurance coverage.

Addressing another viral claim, the government said fuel-grade ethanol contains no sugar. It is denatured for industrial use, and the smell of petrol dominates, making claims that it attracts ants or bees scientifically baseless.

The ministry also clarified that a court case cited on social media was related to ethanol procurement contracts, not the legality or safety of the E20 programme.

It further stated that modern vehicles and fuel stations are equipped with systems that prevent water contamination in fuel tanks. The government also labelled viral videos showing sugarcane juice being mixed directly into petrol as fake, explaining that fuel-grade ethanol is produced through a regulated industrial process and meets strict quality standards.

Highlighting the programme's benefits, the government said ethanol blending has helped India save more than ₹1.9 lakh crore in crude oil import costs. It added that farmers have earned over ₹1.6 lakh crore through ethanol production, while crude oil imports have been reduced by 31 million metric tonnes, contributing to lower emissions and reduced pollution.
