E20 Fuel: India's Ethanol Blend Plans Face Challenges
India is switching to petrol with 20% ethanol, called E20.
This is to help the environment and use less imported fuel.
E20 is made from things like sugarcane.
Newer cars are designed to work with E20.
Older cars might need changes because ethanol can damage parts.
E20 might slightly reduce how far a car can go on a tank of gas.
The government is encouraging more ethanol production.
The switch to E20 is planned for 2025, but there will be some problems with older vehicles.
E20 fuel contains 20% ethanol and 80% petrol.
The government lifted restrictions on ethanol production for 2025-26.
E20 aims to reduce petroleum imports and promote cleaner combustion.
Older vehicles may require retrofitting due to ethanol's corrosive properties.
Mileage reduction is estimated at 1-6% depending on the vehicle.
