India’s government and vehicle manufacturers respond to public concerns about mandatory E20 petrol, which contains up to 20% ethanol. The government issues a 10-point clarification and says the E20 programme is supported by scientific studies, regulatory safeguards, and international experience. It also addresses circulating claims on social media, stating that ethanol blending in petrol does not damage vehicle engines. Industry representatives similarly assert that they have not observed engine damage following implementation. At the same time, both sides acknowledge potential performance changes for some older vehicles. The expected impact is described as marginal: older models may see a slight reduction in fuel efficiency, attributed to ethanol having a lower calorific value than petrol. Field experience so far is described as generally positive. Separately, manufacturers say discussions with the government continue on developing flex-fuel vehicles as a longer-term pathway to better accommodate ethanol-blended fuel. Overall, the communications emphasize engine compatibility and safety while noting limited efficiency effects for older vehicles.
