3 to 5 percent - that is the mileage some drivers are losing at the pump right now and the government's own Ministry admitted it in writing. The real story isn't the number. It's why the Ministry chose to publish it instead of burying it.

WHO ACTUALLY PAYS FOR INDIA'S ETHANOL BET 3 to 5 percent. That is the mileage loss the Ministry of Petroleum and Natural Gas admitted to in its own FAQ document - not a leaked estimate, not an opposition claim, but the government's own number, published voluntarily.

For the average car owner filling up at any of India's one lakh-plus retail outlets, that is a real, recurring cost measured in extra trips to the pump. The interesting question isn't whether the loss exists - the government has conceded that it does.

The interesting question is who is actually absorbing the cost of India's ethanol transition and why the government decided this particular trade-off was worth defending publicly rather than quietly managing. THE PERSON PAYING TODAY IS NOT THE PERSON THE POLICY IS DESIGNED FOR Ethanol procurement is fixed at ₹71.86 per litre for maize-based supply - a price set high enough to guarantee farmers a stable, remunerative income regardless of what crude oil is doing globally.

That fixed floor is exactly why, when international crude sits around $70 a barrel, E20 ends up costlier to produce than plain petrol: the farmer's price doesn't fall with oil, but the market alternative does. The driver at the pump ends up cross-subsidising the farmer's price stability, through mileage loss now, without directly seeing that transfer reflected in a lower price today.

The Ministry's own defence - "public policy must balance consumer interest with energy security, environmental sustainability, farmer welfare" - is, read carefully, an admission that these interests do not currently align; someone has to bear the near-term cost while the others catch up.

WHY THE GOVERNMENT ISN'T BACKING DOWN The government's refusal to offer a pure-petrol option isn't just administrative convenience, even though it frames it that way - citing the "enormous logistical challenge" of stocking multiple fuel grades across a vast retail network.

It's also about sunk capital: nearly ₹1 lakh crore a year in bank-financed ethanol infrastructure, built on the assumption that E20 is the standard, permanent product. Reversing course now wouldn't just annoy consumers already adjusted to E20 - it would strand investments made by farmers, cooperatives and public sector banks who acted in good faith on a stated national policy.

That sunk-cost logic is precisely why the Ministry is choosing transparency about the mileage hit over silence: it needs public buy-in to hold the line against reversal, not just tolerance of the current arrangement. This is the mechanism a general summary would miss: the mileage loss isn't a side effect the government is managing away.

It's the visible price tag of a cross-subsidy running from urban and semi-urban vehicle owners to rural ethanol producers, wrapped inside a broader energy-security bet against crude-price volatility. Whether that trade-off is fair depends entirely on whose costs you're counting - which is exactly the kind of tension a GS3 answer on energy policy should surface, rather than treating "energy security" and "consumer welfare" as automatically compatible goals.
