One of the most common assumptions about E20 is that blending 20 percent ethanol — a cheaper feedstock — into petrol should make the final product cheaper. It does not. The government itself has confirmed this. This article explains why, with the numbers.

The price at the pump: May 2026

On May 1, 2026 — exactly one month after E20 became the only petrol sold in India — fuel prices were hiked by ₹5.61 per litre in Delhi. Not reduced. Hiked. The price went to ₹102.12 per litre in Delhi, with other cities seeing similar or higher levels:

CityPetrol price (₹/litre, July 2026)
Ahmedabad₹102.01
Delhi₹102.12
Chennai₹107.76
Bengaluru₹110.44
Mumbai₹111.21
Kolkata₹113.51
Hyderabad₹115.73

These are E20 prices. There is no E0 or E10 option at a lower price. There is no option at all.

The government’s own admission

In a FAQ published in 2026, the Ministry of Petroleum & Natural Gas (MoPNG)stated plainly that E20 is costlier to produce than pure petrol at current crude-oil prices. This was reported independently by both Business Today and The Federal.

The logic: ethanol procurement in India currently costs around ₹71.86 per litrefor maize-based ethanol (one of the primary feedstocks). E20 petrol would only be cheaper than E0 if crude oil prices were in the range of $120–130 per barrel. As of mid-2026, Brent crude has been trading between $70 and $85. At these prices, blending ethanol into petrolraises the production cost, it does not lower it.

So why does the government push E20 as a cost saver?

The government’s cost argument is about macro-level forex savings, not consumer savings. The claim is that replacing imported crude oil with domestically produced ethanol reduces India’s foreign exchange outflow. The Ministry has cited cumulative savings of ₹1.36 lakh crore in crude imports since the blending programme began.

This is a sovereign balance-of-payments argument. It may or may not hold up to scrutiny (ethanol production itself requires inputs with import components, and the opportunity cost of diverting agricultural land to fuel crops is debated). But even if it does hold, it is irrelevant to the consumer question: you are not paying less at the pump.

The forex savings accrue to the national accounts. The cost is borne by individual vehicle owners through unchanged-or-higher pump prices and reduced mileage.

The hidden cost: less energy per litre

Even if the per-litre price had stayed the same (it didn’t — it went up), the effective cost of driving would still have risen. E20 delivers about 6–7 percent less energy per litre than pure petrol because ethanol has roughly a third less energy content. To travel the same distance, you burn more litres. For a detailed mileage breakdown, see our companion article.

So the real consumer equation is:

The real math

  • Price per litre: same or higher
  • Energy per litre: 6–7% less
  • Litres needed for the same distance: more
  • Net cost to the consumer: higher

Who captures the value?

If the consumer is not saving money, where does the economic benefit go?

  • Ethanol producers and distillers: The government guarantees procurement at administered prices. Ethanol production has become an enormously profitable business. Companies in the space have seen revenue growth of 10x or more.
  • Sugar mills (diversifying into ethanol): India’s sugar industry has pivoted significant capacity toward ethanol, backed by government subsidies, soft loans, and guaranteed offtake.
  • The exchequer: Taxes on petrol (central excise + state VAT) are levied on the per-litre price. If consumers burn more litres for the same distance, total tax collection can rise even without a rate change.

The losers are clear: every vehicle owner paying the same or more for fuel that goes less far.

Comparison: what would E0 cost today?

This is the question no one in government answers. If E20 is costlier to produce than pure petrol at current crude prices, what would E0 cost at the pump? The answer depends on assumptions about refinery margins, tax structure, and whether the government would pass the production savings through to consumers. But directionally, the government’s own FAQ implies that E0 would be either cheaper or no more expensive than E20 — and it would deliver more energy per litre.

This is why the demand for fuel choice is also a demand for price competition. If E0, E5, E10, and E20 were all available, consumers could compare the cost per kilometre and choose the fuel that makes economic sense for their vehicle. The current monopoly on E20 removes that choice entirely.

The price paradox, summarised

ClaimReality
“E20 saves consumers money”Pump prices went up, not down. MoPNG says E20 is costlier to produce at current crude prices.
“Ethanol is cheaper than petrol”Only at crude $120+/barrel. Current crude: $70–85. At today’s prices, ethanol is the more expensive component.
“E20 saves the country ₹1.36 lakh crore”A forex/import-bill argument. Does not mean consumers pay less — they pay the same or more for fewer km.
“Blending brings down fuel prices”No mechanism for this exists. OMCs set prices; the govt sets ethanol procurement prices. Neither is linked to consumer savings.

E20 is not cheaper for consumers by any measure — per litre, per kilometre, or per month. The government’s cost argument is about national forex savings, not your fuel bill. The demand is straightforward: if E20 is more expensive and delivers less energy, let consumers choose. Bring back E0 and E10 alongside E20, and let the market decide.
