India hit 20% blending target ahead of schedule
The government on Friday issued a detailed rebuttal to what it described as misinformation circulating on social media about India’s E20 ethanol blending programme, rejecting claims ranging from excessive water consumption and engine damage to insurance invalidation and environmental harm.
In a 10-point clarification, the Ministry of Petroleum and Natural Gas said the programme — under which petrol contains up to 20 per cent ethanol — is supported by scientific studies, international experience and regulatory safeguards.
Water consumption claims rejected
Addressing claims that producing one litre of ethanol consumes 10,000 litres of water, the ministry clarified that only surplus rice, cleared after meeting national food security requirements, is diverted for ethanol production. It said ethanol distilleries consume about 3-5 litres of processed water per litre of ethanol and are increasingly adopting Zero Liquid Discharge systems to recycle water. The ministry added that maize, which now accounts for more than 40 per cent of ethanol supplied under the programme, requires significantly less irrigation than paddy and is being promoted through higher minimum support prices.
E20 not an untested fuel, government says
The government dismissed claims that E20 is untested, pointing out that ethanol-blended fuels have been used internationally for decades in countries including the United States, Brazil, Canada, Thailand, Japan and several European nations.
No significant impact on vehicle performance, ARAI trials show
On concerns over drivability, the ministry cited Automotive Research Association of India (ARAI)-led trials covering roughly 40,000 kilometres in passenger cars and 20,000 kilometres in two-wheelers, which found no significant adverse impact on drivability or fuel efficiency, with only marginal changes in mileage. It added that vehicles calibrated for E20 could actually benefit from ethanol’s higher octane rating.
Engine damage and corrosion claims dismissed
Responding to allegations that E20 damages engines or corrodes components, the ministry cited joint studies by ARAI, Indian Oil Corporation, the Indian Institute of Petroleum and the Society of Indian Automobile Manufacturers, which found no issues with drivability or compatibility of metal and plastic components — though certain rubber parts in older vehicles may need earlier replacement.
Warranty, insurance coverage unaffected, ministry clarifies
The ministry also rejected claims that using E20 could void vehicle warranties or insurance coverage, noting that manufacturers and insurers have confirmed vehicles designed or approved for E20 remain covered under existing warranty and insurance terms.
Insects-attracted-to-fuel claims called false
On viral posts suggesting ants and bees are drawn to E20 because it contains sugar, the ministry said fuel-grade ethanol undergoes distillation that removes residual sugars and includes denaturants that repel insects, with petrol’s hydrocarbon odour dominating the blend regardless.
Supreme Court “experiment” claim called inaccurate
The government also denied reports claiming it had described the E20 programme as an “experiment” before the Supreme Court, clarifying that the court proceedings concerned contractual provisions on ethanol procurement, not the programme’s merits. It cited a clarification from the Office of the Attorney General stating that media reports suggesting otherwise were inaccurate.
Water ingress and sugarcane-juice videos dismissed as fabricated
The ministry rejected claims that E20 allows water to enter vehicle fuel tanks, saying modern vehicles and retail fuel infrastructure have built-in safeguards against water ingress. It also described viral videos purporting to show sugarcane juice being mixed into petrol as fabricated, noting that fuel ethanol is manufactured through industrial processes under prescribed quality specifications.
Environmental safeguards and savings highlighted
On environmental concerns, the government said ethanol plants require statutory environmental clearances, must comply with groundwater regulations, and are mandated to run Zero Liquid Discharge systems. It said the programme has delivered foreign exchange savings exceeding Rs 1.9 lakh crore, expedited farmer payments of more than Rs 1.6 lakh crore, cut carbon dioxide emissions by around 930 lakh metric tonnes, and displaced over 310 lakh metric tonnes of crude oil imports since 2014-15.
India hit 20% blending target ahead of schedule
India achieved its 20 per cent ethanol blending target in petrol in December 2025, ahead of schedule, up from about 1.5 per cent in 2013-14, the ministry said. Installed ethanol production capacity has reached approximately 2,000 crore litres, with procurement projected to exceed 1,200 crore litres during the 2025-26 ethanol supply year.
