E27 Fuel Explained: What 27% Ethanol In Petrol Means For Your Car, Mileage & Wallet

India’s move to increase ethanol blending in petrol from 20% to 27% (E27) brings environmental and economic benefits, but also raises key concerns for consumers. Ethanol is made from crops like sugarcane and maize—so diverting more for fuel could reduce food supply and push up prices. At the same time, ethanol has lower energy content than petrol, which can reduce mileage by 5–10%, leading to higher fuel costs over time. Most existing vehicles aren’t fully compatible with higher ethanol blends, raising risks of engine wear and corrosion. While the policy supports sustainability, it may strain consumer wallets in the short term.
