Ethanol Blending Fuels Performance Concerns in India
Adding ethanol to petrol can cause problems for cars.
Ethanol has less energy than petrol, so cars may use more fuel.
Older cars can be damaged by the mix.
The fuel mix may corrode fuel tanks, damage fuel pumps, fuel injection systems and can scar engine cylinder walls, potentially leading to long-term damage.
Many people don't like the change and believe this impacts performance.
Using high-octane fuel without ethanol is a safer solution, but more expensive.
Many E20 users report decreased mileage and performance.
Ethanol has a lower energy density than petrol, affecting mileage.
Older cars may experience corrosion and engine damage with E20.
A survey shows a majority are against the government's move to mandate ethanol-blended fuel.
100-octane petrol is a safer but more expensive option for older vehicles.
