E100 Petrol In India: Can Your Regular Car Run On 100% Ethanol? Explained

India has opened the regulatory pathway for vehicles designed to run on higher ethanol blends, including E100. But does this mean you can fill your regular petrol car with pure ethanol? Absolutely not. Flex-fuel vehicles are specially engineered to handle different petrol-ethanol mixtures, while ordinary petrol cars have specific fuel compatibility limits. India Today TV’s Akshita Nandagopal explains the difference between E20, E85 and E100, what the government’s latest rule changes mean, and why India is promoting ethanol as an alternative fuel. The explainer also examines concerns around mileage, engine compatibility and the cost for vehicle owners.
