Growing Complaints Cloud India's E20 Rollout

Complaints about E20 petrol are no longer confined to the world of social media threads. A fresh nationwide survey and accounts from workshop owners across India point to a widening gap between official assurances and what pre-2023 vehicle owners say they are experiencing on the road.A survey conducted by LocalCircles in June 2026 found that 66% of owners of pre-2023 petrol vehicles reported a fuel efficiency drop of more than 10%. This was up sharply from 45% in a similar survey the platform ran in May 2026.
