India's E20 Petrol Rollout Raises Vehicle Concerns Amid Shift Toward Higher Ethanol Fuels
India has implemented E20 petrol nationwide to reduce crude oil imports and boost domestic ethanol production. A survey found nearly half of owners of older petrol vehicles report reduced mileage and some engine issues since the rollout, raising concerns about ethanol's effects on vehicle components. Meanwhile, policymakers and automakers are discussing higher ethanol blends like E100 fuel, which could further decrease fuel imports and support sustainability goals, especially for compatible flex-fuel vehicles.
