- E20 Petrol may cost more at $70 crude.
- Government highlights energy security over immediate fuel savings.
The Government of India has stated that producing E20 petrol can be more expensive than manufacturing conventional petrol when international crude oil prices remain around US$70 per barrel. The clarification challenges the common belief that blending ethanol into petrol automatically lowers fuel costs. According to the Ministry of Petroleum and Natural Gas, the objective of the ethanol blending programme extends beyond short-term fuel pricing and instead focuses on strengthening India's long-term energy security, reducing dependence on imported crude oil and supporting domestic agricultural production.
Why E20 Petrol Can Cost More at Lower Crude Oil Prices
The ministry explained that maize-based ethanol is currently procured at approximately ₹71.86 per litre, excluding goods and services tax, transportation, storage and handling expenses. Since E20 fuel consists of 20% ethanol and 80% petrol, the cost of the ethanol portion remains fixed through government procurement mechanisms designed to provide stable returns to domestic producers and farmers. As a result, when international crude oil trades near US$70 per barrel, the overall production cost of E20 can exceed that of conventional petrol.
How Rising Crude Prices Change the Economics
The ministry noted that the economic comparison changes significantly when crude oil prices increase. If international crude prices rise to approximately US$120-130 per barrel, ethanol becomes relatively cheaper than petrol refined from imported crude oil. Therefore, whether E20 costs more or less than pure petrol depends on global crude prices together with ethanol procurement costs rather than remaining constant under all market conditions.
Key Cost Factors Affecting E20 Fuel Production
The overall production cost depends on several variables beyond crude oil prices. These include the type of ethanol feedstock used, taxes, logistics and distribution expenses. Ethanol procurement prices also differ according to feedstock.
Government-Notified Provisional FY26 Ethanol Procurement Prices
| Feedstock | Procurement Price (₹/Litre) |
|---|---|
| C-heavy molasses | 57.97 |
| B-heavy molasses | 60.73 |
| Maize-based ethanol | 71.86 |
Domestic Ethanol Provides Stability Against Global Volatility
The ministry stated that nearly one-fifth of petrol consumed in India now comes from domestically produced ethanol. Unlike imported crude oil, the procurement price of ethanol does not fluctuate daily because of geopolitical events, shipping disruptions or movements in international benchmark crude prices. This fixed domestic component helps reduce the impact of sudden changes in global oil markets on the country's overall fuel supply.
Average ethanol blending reached 20% between November 2025 and June 2026, compared with 19.2% during the previous ethanol supply year. However, the ministry also clarified that actual E20 production costs vary depending on the combination of ethanol feedstocks, taxes, transportation costs, storage charges, dealer margins and the price of the petrol component. It did not publish city-wise comparisons between E20 production costs and retail petrol prices.
Government Focuses on Long-Term National Benefits
According to the Ministry of Petroleum and Natural Gas, the ethanol blending programme should be evaluated based on its broader economic and strategic benefits rather than only on daily fuel prices. The government estimates that since the 2014-15 ethanol supply year, the programme has saved more than ₹1.97 lakh crore in foreign exchange, displaced nearly 316 lakh tonnes of crude oil imports and transferred over ₹1.66 lakh crore to farmers through ethanol procurement. These outcomes are intended to strengthen energy security while reducing exposure to fluctuations in global crude oil markets.
The ministry also emphasized that its assessment should not be interpreted to mean E20 is always more expensive than conventional petrol. The cost comparison varies with international crude oil prices, ethanol feedstock costs, taxation, logistics and other market factors that influence the final production and retail price.
Frequently Asked Questions
Why can E20 petrol cost more than pure petrol?
E20 petrol can cost more when international crude oil prices are around US$70 per barrel because ethanol used in the blend is procured at fixed government prices that support domestic producers and farmers. Additional expenses such as taxes, transportation, storage, dealer margins and the mix of ethanol feedstocks also influence production costs. The comparison changes as crude oil prices fluctuate, meaning E20 is not always more expensive than conventional petrol.
What are the main benefits of India's ethanol blending programme?
The government's ethanol blending programme aims to improve long-term energy security rather than simply reduce daily fuel prices. It helps lower dependence on imported crude oil, reduces exposure to global oil price volatility, supports domestic farmers through ethanol procurement and saves foreign exchange by replacing imported crude with locally produced ethanol. These broader economic and strategic benefits remain central to the programme even when E20 production costs temporarily exceed those of pure petrol.
