The Ministry of Petroleum and Natural Gas has categorically dismissed social media rumors claiming that ethanol-blended petrol is causing ants to swarm vehicle fuel tanks. Clarifying the government's stance during a press briefing on Tuesday, officials stated that the integration of ethanol into petrol is a strictly scientific process subjected to continuous quality monitoring.

The clarification comes in the wake of a viral video showing ants crawling near a vehicle's fuel tank, sparking speculation that the fuel contains raw sugarcane juice.

Fuel-Grade Ethanol Contains No Sugar, Says Ministry

"Fuel-grade ethanol contains absolutely no sugar," the ministry stated, adding that malicious actors are recycling old, unverified videos and photographs to trigger panic among motorists.

Authorities confirmed that there have been zero validated reports of engine damage linked to the use of E20 petrol across the country. Addressing separate consumer anxieties regarding vehicle insurance validity, the Central government explicitly stated that using E20 fuel (petrol blended with 20% ethanol) has absolutely no bearing on insurance policies, a consensus reached after thorough consultations with industry stakeholders.

Global Precedent and Rs 1.4 Lakh Crore Savings

To counter domestic skepticism, officials pointed out that ethanol-blended fuels have been successfully deployed for years in major global economies. Brazil has long relied on E27 blends, while the United States and Japan maintain extensive blending programs.

The government highlighted three primary macroeconomic breakthroughs driven by India's domestic ethanol program:

• Foreign Exchange Savings: The reduction in crude oil imports has saved the national exchequer over ₹1.4 lakh crore in foreign exchange to date.

• Rural Economy Boost: Surging demand for agricultural feedstock used in ethanol production has provided a direct price support mechanism for farmers, strengthening rural liquidity.

• Energy Security & Decarbonization: Increased blending is actively reducing the country's carbon footprint while insulating it against global oil volatility.

Understanding the Chemistry and Generation of Ethanol

Technically an alcohol derived from the fermentation of starch and sugars, ethanol serves as an eco-friendly fuel additive. While sugarcane juice remains a primary source, it is increasingly produced from agricultural waste, damaged food grains, maize, and rotten potatoes.

Production is categorized across distinct phases:

1. First Generation (1G): Derived directly from sugarcane juice, sugar beet, damaged potatoes, sweet sorghum, and maize.

2. Second Generation (2G): Sourced from cellulosic and lignocellulosic biomass like rice straw, wheat straw, corncobs, bamboo, and woody biomass.

3. Third Generation (3G): Currently under development, focusing on advanced biofuels derived from algae.

The Push for Flex-Fuel and E85

The government's push for alternative biofuels hit a major milestone just a fortnight ago with the introduction of E85 fuel for flex-fuel vehicles. Retailing at ₹82.12 per liter in New Delhi, E85—which features a blend of up to 85% ethanol and 15% petrol—is significantly cheaper than regular E20 petrol, undercutting it by a flat ₹20 per liter.

However, the ministry cautioned that E85 cannot be pumped into standard petrol engines. It requires dedicated flex-fuel technology capable of recalibrating for high-ethanol concentration.

Among the compliant fleet ready for the transition is the Maruti Suzuki WagonR Flex-Fuel, India’s first mass-market car engineered to run on blends up to E100. In the two-wheeler segment, Hero MotoCorp is set to retail its flex-fuel iterations of the Splendor+ and HF Deluxe in selected regions of Delhi and Maharashtra starting July 2026, while the Suzuki Gixxer SF also stands certified for high-ethanol compatibility.

This infrastructure push coincides with Union Road Transport Minister Nitin Gadkari’s recent policy announcement in Nagpur, where the government gave its formal nod to 100% pure ethanol (E100) as an official fuel type.

Despite official assurances, local mechanics in transit hubs like Delhi report a contrasting narrative on the ground. Some independent garage owners claim an uptick in fuel-sensor failures and moisture-linked corrosion inside older fuel tanks over the last two years, attributing it to the hygroscopic nature of ethanol. Government agencies, however, maintain that standardized vehicle manufacturing compliant with E20 norms completely mitigates these risks.
