India’s transition to E20 petrol offers an opportunity to enhance energy security, reduce crude oil imports, and promote environmental sustainability. However, for ordinary citizens, the shift raises concerns about vehicle compatibility, fuel efficiency, costs, and access to accurate information. This research emphasizes the need for an E20 policy that is truly common man–friendly, balancing technological feasibility, consumer protection, and environmental sustainability. The study examines the socio-economic impact on farmers and consumers, evaluates vehicle and infrastructure readiness, and assesses environmental implications of large-scale ethanol adoption. It identifies gaps in the current regulatory framework, showing that reliance on policy notifications and voluntary standards leaves consumers vulnerable to engine issues, warranty exclusions, and inconsistent fuel availability.
