E20 policy faces backlash over mileage and costs

The Frontline reports that widespread protests are mounting against the Indian government's mandatory ethanol-blended petrol (E20) policy, with consumers citing a significant drop in fuel economy and higher repair costs. The government initially denied any mileage loss, then attributed it to driving habits, and has only reluctantly acknowledged a marginal drop, though technical literature confirms ethanol's calorific value is 36% lower than petrol, leading to an estimated mileage reduction of over 7%.

Users have also complained of corrosion in fuel components, forcing frequent repairs. While BS-VI vehicles made after 2023 are likely E20-compliant, older BS-IV and earlier models are not. Vehicle manufacturers initially confirmed the corrosion issue but later retracted statements, allegedly under government pressure. The policy, which follows a pattern of limited concessions amid rising dissent, now threatens to become another serious challenge for the BJP-led government.
