Government Defends E20 Ethanol Blend Amid Efficiency Concerns
The Indian government says that a fuel called E20, which mixes 20% ethanol with petrol, is safe for cars and bikes.
It has a higher octane rating, which helps engines run smoother and cleaner.
Some studies show that cars not designed for E20 may use 2‑6% more fuel, but this depends on how the car is driven and kept.
The government says no major engine damage has been seen in millions of vehicles using E20.
They will not raise the ethanol level until more research is done.
E20 ethanol blend offers higher octane, cleaner combustion, and smoother engine performance.
Studies show a 2‑6% fuel‑efficiency drop in some E10‑designed vehicles, influenced by driving habits and maintenance.
No widespread engine failures or vehicle breakdowns reported in over 20 crore two‑wheelers and 3 crore petrol cars using ethanol blends.
The Ministry of Petroleum and Natural Gas introduced the Ethanol Blended Petrol programme through a consultative process with NITI Aayog, manufacturers, and technical bodies.
Officials will not increase ethanol blending beyond 20% until further scientific studies and stakeholder consultations are completed.
