India just reached E20 petrol. Is pushing to E27 or E30 a smart move or a risk for engines?

With India achieving E20 ethanol blending, policymakers are already discussing E27–E30 blends.

Supporters say it:

• reduces oil imports

• boosts farmer income

• lowers emissions

Critics say it could:

• reduce mileage

• affect engine components not designed for high ethanol

• shift agriculture away from food crops

What do you think — energy independence or unintended consequences?
